Tannery Effluent Treatment with Aerobic System (Flow Rate: 950 KLD)

Key Problems in Handling Tannery Effluent:

High COD and BOD:
Organic matter from hides and chemicals used in tanning lead to very high COD and BOD, making biological treatment challenging and energy-intensive.

Salinity and TDS Issues:
Large quantities of salt used in hide preservation and soaking stages significantly raise the TDS, which affects microbial health and limits reuse potential, requiring high TDS wastewater solutions.

Toxicity from Sulfides and Solvents:
Effluents often carry toxic sulfides and various solvents or dyes that can inhibit biological activity, corrode equipment, and pose environmental hazards.

Reach out to us today to explore effective, sustainable solutions for managing tannery effluent and ensuring compliance with environmental standards.

Sludge Handling and Disposal:
The treatment of tannery wastewater generates hazardous sludge, especially with high chromium content, requiring safe disposal as per hazardous waste norms. This highlights the importance of chromium removal technology in modern industrial effluent treatment solutions.

A tannery ETP with a flow rate of 950 KLD had several basic issues in its aerobic treatment plant. The plant was equipped with a single aeration tank with one partition and a single clarifier. Due to multiple streams and heavy ammoniacal nitrogen, the plant was facing operational inefficiencies.

The Initial Approach

Our team conducted a comprehensive site evaluation to identify issues and areas of improvement. The following key challenges were observed:

  • High COD levels (>10,000 ppm) due to sulfides and other pollutants.
  • BOD levels exceeding discharge standards (>5,000 ppm).
  • Higher Ammoniacal Nitrogen Levels at the outlet of the aeration tank (<450 ppm).
  • Very high MLSS and poor settling.
  • High SRT.

T1B Aerobio: Enhancing Aerobic Treatment Performance

T1B Aerobio is a scientifically formulated microbial consortium designed to optimize aerobic wastewater treatment. Its robust strains have the ability to survive in high TDS wastewater solutions with halophilic strains, degrade ammoniacal nitrogen, sodium acetate, and other nutrients, and perform under variable pH & temperature. The bioculture also secretes various enzymes, regulates sludge levels, and supports sustainable ETP plant operations.

Execution

Plant Optimization:

  • Removal of excess sludge to improve oxygen transfer and microbial activity.
  • The recirculation rate was adjusted, and its stream was uniformly distributed in both sections.

Dosing Regime:
A 60-day dosing schedule was implemented:

  • Phase 1 (Days 1–30): High initial dose to establish microbial dominance.
  • Phase 2 (Days 31–60): Maintenance dose to sustain treatment efficiency.

Monitoring Parameters:

  • COD and BOD reduction.
  • Ammoniacal Nitrogen levels in both aeration tanks.
  • Sludge volume index (SVI) and microbial activity.

Observations

The addition of T1B Aerobio resulted in significant improvements in the aerobic system’s performance. Key observations are summarized below:

Parameters Day 1 Day 15 Day 30 Day 45 Day 60
COD (ppm) 8500 7469 4331 1345 423
BOD (ppm) 3770 2891 1761 760 181
AN (ppm) 652 545 291 166 82

Results

  • COD Reduction: Achieved a 95.02% reduction by Day 60, ensuring compliance with regulatory standards.
  • BOD Reduction: Achieved a 95.19% reduction, meeting safe discharge norms.
  • AN Reduction: Achieved an 87.42% reduction by Day 60, aligning with discharge compliance.
  • Improved Sludge Quality: Enhanced microbial flocculation reduced SVI and improved sludge settling.
  • MLSS Levels: Controlled effectively, improving sludge settling quality.

Conclusion

The application of T1B Aerobio significantly enhanced the performance of the tannery’s aerobic treatment system. The plant achieved regulatory compliance for COD and BOD levels, stabilized DO levels, and improved sludge quality.

GREEN-ENERGY-FROM-WASTEWATER-Biogas-and-Beyond.
Green Energy from Wastewater: How Anaerobic Biocultures Drive Biogas Production in India

The best word that can be an example of a paradox would be ‘Wastewater’. The word itself suggests it’s a waste, and one needs to get rid of it for the sake of saving the environment. But what if I say that this very wastewater can be “useful” too? in chemical energy (think COD/BOD). With the right biology and engineering, you can convert that into biogas, electricity, heat, biomethane (RNG), even hydrogen-and push your plant towards energy neutrality or better.

As one of the agile biotech companies in India, we blend R&D with field deployment for measurable outcomes. We supply targeted biocultures for wastewater treatment to accelerate digestion and reduce operating costs. Our Bioculture programs are designed for both etp and stp facilities, covering shock‑load resilience and sludge reduction. Contact us here.

Why wastewater = energy

Conventional aerobic treatment spends energy on aeration. Anaerobic digestion (AD) flips the script: microbes break down organics in the absence of oxygen and produce biogas (≈55–65% methane) you can burn in CHP engines of oxygen for electricity + heat, or upgrade to biomethane for grid/CNG use. Numerous facilities have demonstrated energy-neutral to energy-positive operation using AD, process efficiency, and on-site generation like the Strass in Austria or Sheboygan in US.

Why going the nature’s way is a game changer?

While anaerobic digestion (AD) is the technology, biocultures are the heart of the process. In AD, specialized microbes break down organics in the absence of oxygen to produce biogas (55-65% methane). The quality and productivity of this gas depend on the microbial community’s health and efficiency. Optimized inoculation and co‑digestion increase biogas production while improving digester stability and dewatering.

Team One Biotech’s anaerobic biocultures are designed to:

  • Rapidly adapt to different waste loads and compositions
  • Boost methane yield and volatile solids reduction
  • Stabilize digestion during shock loads pr toxic events
  • Minimize foaming and scum formation
  • Improve sludge dewaterability, reducing disposal costs

Without strong microbial activity, digestion slows, gas yields drop, and energy recovery becomes uneconomical. We partner with etp stp plant manufacturers to integrate anaerobic digesters, gas handling, and CHP in new builds.

Turning wastewater into Energy: How it works
  1. Anaerobic Digestion + Biocultures

Our Anaerobio biocultures accelerate the breakdown of organics in wastewater and sludge, converting them into methane-rich biogas efficiently and consistently. For plants evaluating anaerobic bioculture price, we provide transparent quotations based on COD load, flow, dosing plan, and target methane yield. We are among reliable anaerobic bioculture suppliers offering consistent strains, QA/QC documentation, and startup support.

  1. Co-Digestion for More Gas

Feeding digesters with FOG (fats, oils, grease), food waste, or dairy residues alongside sludge boosts biogas yields significantly. Our targeted microbial blends handle these high-strength wastes without process instability, giving you more gas from the same infrastructure. Optimized inoculation and co‑digestion increase biogas production while improving digester stability and dewatering.

  1. Biogas Utilize Pathways
  • CHP (Combined Heat & Power) – Run engines on biogas to power blowers, pumps, and heat digesters, cutting energy bills.
  • Biomethane (RNG)-Upgrade biogas for grid injection or CNG vehicles, accessing renewable energy credits and new revenue streams.
  1. Beyond Biogas

Advanced microbial and electrochemical processes are enabling hydrogen production, while wastewater heat recovery systems are capturing thermal energy for building use.

The Business Case

Energy Savings: Reduce grid electricity dependence by up to 80-100% in optimized systems.

Revenue Generation: Sell excess power, biomethane, or renewable energy certificates.

Lower OPEX:  Minimize Sludge disposal costs through higher volatile solids destruction

Sustainability Goals: Lower greenhouse gas emissions and improve ESG scores.

A Practical Roadmap for ETP/STP Owners
  1. Assess your biogas potential — measure COD load and sludge availability.
  2. Strengthen your microbial engine — dose Anaerobio biocultures for faster, more stable digestion.
  3. Explore co-digestion — partner with food industries for high-energy wastes.
  4. Decide your offtake model — CHP for self-powering, or biomethane for revenue.
  5. Plan for future add-ons — hydrogen, nutrient recovery, and heat reuse.
Bottom Line

Wastewater isn’t waste — it’s renewable energy in disguise.
If you operate a biogas generator, gas cleaning (H2S/moisture) and steady feed improve uptime and efficiency. We collaborate with leading green energy companies in india to deliver waste‑to‑energy and biomethane projects. Our portfolio includes end‑to‑end green energy solutions from feasibility to commissioning and operator training.

With the right biocultures, you can turn your plant from an energy consumer into an energy producer, cut operating costs, and generate new revenue streams — all while meeting sustainability goals. Beyond energy recovery, our Bioremediation services address phenols, PAHs, sulfides, FOG, and color bodies.

ReducingReplacing RELIANCE ON MEE in HIGH TDS Effluents
Reducing/Replacing RELIANCE ON MEE in HIGH TDS Effluents

Multi-effect evaporators (MEEs) are widely used in industries dealing with high TDS effluent COD testing. They are highly effective—reducing COD by up to 90–95% even when the TDS of effluent water is extremely high. However, the shine of MEE’s efficiency often masks the significant operational costs that come with it. This blog explores whether MEEs can be replaced or minimized and the role of biological systems in reducing reliance.

This blog explores all sides of this technology and how its usage can be reduced or replaced. Get in touch to learn how innovative bioculture-based treatments can optimize COD reduction and lower operational costs in your effluent systems.

What is an MEE- How it works?

A Multi-effect evaporator (MEE) is an energy–efficient system used to concentrate high-TDS effluents by evaporating water in multiple stages or “effects”. It utilizes steam in the first stage to heat the effluent, causing water to evaporate. The vapor generated is then reused as a heating source for the next stage, progressively reducing energy consumption. This cascading use of steam maximizes thermal efficiency and minimizes operational cost. MEEs are widely used in zero liquid discharge (ZLD) systems, especially in industries with high salinity wastewater. The result is a concentrated brine and distilled water, both of which can be handled or reused appropriately.

Why is MEE in trends?

MEE is one of the most trending technologies in wastewater treatment, owing to its high efficiency in reducing higher levels of COD and tackling tough and toxic effluents with compounds like Cyanide, Toluene, Phenols, and aldehydes. Also, the condensate quality is top-notch. MEE is very popular in industries located near the sea, as it has excellent efficiency up to 98% in effluents with COD up to 150000 PPM and above, and delivers in TDS above 100000 PPM as the sea discharge with higher TDS is permissible.

Technology comes at a Cost

Multiple Effect Evaporator (MEE) systems, while highly efficient in reducing wastewater volume and achieving zero liquid discharge (ZLD), are often cost-prohibitive for many industries. The initial capital investment for an MEE plant typically ranges from Rs 50 lakh to Rs 2 crore, depending on capacity and design complexity.

Operational costs are also steep—electricity and fuel expenses can exceed Rs. 3-5 per liter of treated effluent, especially when steam boilers or thermic fluid heaters are involved. Despite incorporating energy recovery through multiple effects, MEEs still consume 1.2-1.5 kg of steam per liter of evaporated water.

Maintenance adds another layer of expense; anti-scalant chemicals, descaling routines, and part replacements can cost Rs. 5-10 lakh annually for a mid-sized plant. Skilled manpower and automation support further raise the cost.

Additionally, industries must manage the disposal of high-TDS concentrate or salts, which may cost Rs. 2-3 per kg in transport and treatment. Pre-treatment requirements—like neutralization, oil removal, or biological treatment-can add another Rs. 0.5-1 per litre.

While MEE ensures regulatory compliance and high performance, the total cost of ownership makes it unviable for many small and medium enterprises. Hence, despite its technical merits, MEE remains financially challenging, pushing industries to explore cost-effective biological or hybrid solutions.

 

What are the alternatives?

MEEs are known to reduce high COD values in effluents with high TDS values. Hence, it may sound ridiculous, but the best alternatives are BIOCULTURES. Now, the first question coming into the readers’ minds will be Why & How?

Well, let’s first answer Why? There is a certain class of bacteria that survives and thrives in extremely high saline conditions called Halophilic bacteria. These bacteria, when combined with other strains, as biocultures, can effectively work in high TDS effluents and reduce COD with great efficiency.

Now, let’s find out how?

The best way is to gradually divert the primary treated influent stream/inlet stream to MEE to the aeration tank.

Suppose A MEE has a capacity of 30 KLD that treats a stream with COD 75000 and TDS 50000, and the ETP is of 200 KLD that handles an inlet COD of 10000 PPM. In this case, initially, a stream of 5 KLD inlet to MEE can be diverted to the 200 KLD ETP. Then the average COD can be calculated by the below formula:

formula

Hence, the average inlet of 200 KLD ETP after diverting 5 KLD ETP will be approximately 12000 PPM, which can be treated by effective biocultures with strains of halophilic bacteria.

The 5 KLD stream can be increased to 10 KLD and 15 KLD, depending on the performance of the ETP.

How can this strategy be a game-changer?

Well, it is self-explanatory from the above information that diverting the MEE stream can reduce OPEX up to 30-35% straightaway, along with increasing the efficiency of the ETP. However, this strategy is more applicable in industries where sea discharge with High TDS effluent is permitted. But, it is not restricted also; options can be analysed too in other cases.

Technical efficiency and product viability is a must

While, the strategy looks very easy on paper but it is very tough to execute. It requires technical know-how of the whole plant, analysis of trends, and effective identification of strains and its amalgamation into an effective bioculture, its dosing and most important acumen of troubleshooting in real-time as we will be handling a stream which is very toxic , filled with tough-to degrade and shock load inducing compounds.

Treating Petroleum refinery effluent with high Sulfide concentration
Industrial Wastewater Treatment for Petroleum Refineries: High Sulfide Removal Using Biocultures

A reputed petroleum refinery approached us due to high concentration of sulfides in their effluents. They tried multiple solutions, including electroplating, RO, etc., but they were very cost-intensive. Also, they received multiple notices from the pollution control board and were paying heavy fines.

In such industries wastewater treatment methods like RO and chemical dosing prove unsustainable so we offered them biological wastewater treatment as an eco-friendly alternative.

To upgrade your facility’s efficiency with proven biological wastewater treatment methods, microbial solutions, and expert consultation, Contact Us.

 
ETP Details:
Parameter Value
Flow (current) 450 KLD
Flow (design) 450 KLD
Type of process Facultative
Capacity of UASB 1250 KL
Capacity of AT 450 KL
Retention Time 90.66 hours (combined)

Challenges:

Parameters (PPM) Avg. Inlet Avg. Outlet

PAH 1250 680
 
Operational Challenges:
  • The primary treatment was working at 10% efficiency in terms of COD reduction
  • The biological treatment worked at an average of 50% efficiency in terms of COD reduction

They were struggling to control the higher Sulfide levels, and it was inducing shock loads as explained earlier. In this case, the Inadequate aeration in water treatment,   systems contributed to sulfide accumulation, highlighting the need for advanced ETP water treatment process design and management.

 
Tackling Sulfides in ETPs:

To tackle sulfides in ETP, the presence of SOBs or sulfide-oxidising bacteria is a must. The SOBs oxidize sulfides into sulfates. To prevent sulfate accumulation, SRBs or sulfur-reducing bacteria are required; however, SRBs are only effective in anaerobic systems.

Issues with Process:

The main issue with the process was that there was no provision of a separate aeration tank before UASB, where sulfides need to be oxidized into sulfates. This gap in the industrial wastewater treatment design reduced system effectiveness and highlighted the importance of using effective biocultures for wastewater treatment.

 
The Approach:

The industry partnered with us to commission their UASB and aeration tank with increased capacity and restart the plant at its full capacity in terms of hydraulic load.

We adopted a 3D approach:

  1. Research/Scrutiny:
  • Our team visited their facility to go through the process of the new ETP and to scrutinize the value-addition factors.
  1. Analysis:
  • We analyzed the 3-month cumulative data of their ETP to see trends in the inlet-outlet parameters’ variations and the permutation combinations related to it.
  1. Innovation:
  • After the research and analysis, our team curated customized products and their dosing schedules with formulation keeping in mind the plan of action to get the desired results.

This process is called bioaugmentation.
Our tailor-made microbial blends reflect Team One Biotech’s leadership among top biotech companies in India, offering scalable solutions based on site-specific microbial demand.

Desired Outcomes:

  1. Reduction in Sulfide levels in the final outlet
  2. Development of strong biology to withstand shock loads and prevent upsets
  3. Making ETP more efficient regarding COD/BOD and PAH degradation
  4. Reduction in FOG
  5. Improved microbial culture for wastewater treatment effectiveness under both aerobic and anaerobic conditions

Plan of Action:

  1. A tank of 300 KL before UASB was converted into an aerobic tank, and T1B Aerobio with SOBs was dosed for sulfide oxidation.
  2. T1B Anaerobio was dosed in UASB for sulfate and COD reduction.
  3. The addition of T1B Aerobio was also done in the aeration tank after UASB every day.

This strategic integration of wastewater treatment methods significantly boosted operational stability and treatment consistency.

 
Results:
Parameters (PPM) Avg. Inlet Avg. Outlet (Secondary Clarifier)
COD 5500–9010 900–1300
BOD 2500–5800 350–750
Sulfides 2000 180
PAH 1250 220
 
Before & After Bioaugmentation:

Performance Highlights:
  • The COD/BOD degrading efficiency increased from 50% to 83%
  • Sulfide reduction was achieved up to 91%
  • PAH was also getting degraded up to 82.4%
  • MLSS: MLVSS ratio was optimized
  • Biomass in the ASP system displayed great stability even during shock load situations

Sulphate Removal in Wastewater Treatment Challenges, Methods & Field Realities
Sulphate Removal in Industrial Wastewater Treatment-Challenges, Methods & Field Realities

Sulphate removal from wastewater has led to stricter regulations on industrial discharge due to its impact on environmental infrastructure. Specifically, in industries like textile, and tanning sectors, the sulfate in textile dyeing effluents can accelerate corrosion from sulphate and burden downstream processes

Sulphate (SO42- ) is a naturally occurring anion commonly found in industrial wastewater, particularly from:

  • Textile dying and printing (due to sodium sulfate and sulfur-based dyes)
  • Pulp and Paper (via bleaching agents)
  • Tanneries
  • Pharmaceutical and chemical industries (acid-base reactions, reaction byproducts)

While sulfate is non-toxic at low levels, high sulfate concentrations (>1000–1500 mg/L) can cause:

  • Corrosion of concrete and metal ETP infrastructure

  • Toxic hydrogen sulphide (H₂S) generation under anaerobic sludge conditions

  • Soil and crop damage if treated water is reused in agriculture

  • Ecosystem stress upon discharge into surface water

Reach out to us to learn how our advanced bioculture and treatment solutions can efficiently manage sulfate in industrial wastewater.

Understanding sulfate concentration limits in each industry is crucial for designing appropriate industrial effluent treatment plant strategies. Tailored treatment of sulfate-rich industrial effluent helps ensure effluent sulfate compliance and sustainable operations.

Mechanisms of Sulphate Removal

Among the chemical methods, gypsum precipitation using lime and barium chloride precipitation are still widely discussed in specialized treatment scenarios.*

However, these techniques often fall short when handling high COD to sulphate ratio environments, calling for integrated solutions.

Sulfate cannot be removed by conventional BOD/COD treatment processes.

It requires targeted strategies, categorized below:

  1. Chemical Precipitation:

Principle: Convert sulfate ions into insoluble salts for removal via sedimentation or filtration.

Pros: Fast, controllable

Cons: Expensive. High sludge volume, safety hazards ( Ba2+ toxicity)

  1. Biological Sulfate Reduction (BSR)

The growing preference for biological sulfate reduction stems from its adaptability to anaerobic sludge zones and reduced operational costs over time. For many ETPs, BSR bioreactor design now forms the core of sulfate management.

Recent advances in anaerobic treatment process technology enable desulfovibrio bacteria and other SRBs to work efficiently even under high sulphate from chemical manufacturing loads.

What is BSR?

Biological Sulfate Reduction (BSR) is a natural microbial process in which sulfate-reducing bacteria (SRB) convert sulfate (SO42- ) to hydrogen sulphide (H2S) under strictly anaerobic conditions.

The SRBs utilize sulfate as a terminal electron acceptor, similar to how aerobic bacteria use oxygen. The carbon source (typically lactate, acetate or ethanol) serves as the electron donor.

Typical reaction:

SO₄²⁻ + Organic matter → H₂S + CO₂ + Biomass

The process is energy-generating for the bacteria and occurs naturally in anaerobic environments such as sediments, digesters, and deep sludge zones.

Key Microbial Players:

Operating Conditions for BSR:

Maintaining correct redox potential in ETP and ensuring low sulfide toxicity in bioreactors are essential for optimal performance of sulphate-reducing bacteria.

Several studies suggest adding specific carbon sources in sulfate-rich wastewater can improve outcomes in mesophilic BSR operation.

System Configurations for BSR:

BSR can be integrated into ETPs in the following configurations:

  • Dedicated Anaerobic Suphate Reduction Bioreactor (SBBR)

Compact take or plug-flow reactors packed with anaerobic sludge

  • UASB Reactors

Natural sulfide reduction may occur in deeper sludge blanket zones

  • Anaerobic Biofilters or Reactors with Immobilized SRBs
  • Hybrid Reactors

Combining SRB zone with methanogenic or denitrification sections

  • Constructed wetlands

With anaerobic root zones and carbon-rich substrates.

H2S Management Post-BSR

Advanced plants now include FeS precipitation method and oxidation with oxygen as standard steps for managing H₂S in wastewater.

In systems handling acid-base waste management, this step is particularly crucial to avoid cross-reactions and odour complaints.*

A major by-product of BSR is hydrogen sulphide (H2S)- which is:

  • Toxic to humans and microbes at even low ppm levels
  • Corrosive to concrete and metal surfaces
  • Malodorous (rotten egg smell)

Common removal or control methods include:

Advantages of BSR

For facilities treating sulphate from tanning processes or sulfate in bleaching process, BSR offers a more stable and adaptable solution compared to chemical routes.

  • Sustainable and low operating cost (after seeding & startup)
  • High sulfate removal efficiency (>90%)
  • Can operate under high TDS and COD conditions( with acclimatized culture)
  • Reduces corrosion potential if followed by H2S polishing
Challenges in BSR
  1. Hydrogen Sulfide Capture (Post-BSR Step)

Because BSR produces H2S, you must neutralize or remove it:

Is Your ETP Ready for Sulfate Compliance?

If your facility is part of the pulp mill wastewater sulfate stream or pharma effluent sulfate levels are high, integrating a sulfate removal technology like BSR or hybrid reactors is not optional—it’s essential.

Moreover, plants without anaerobic bioreactor for sulphate zones risk failing standards repeatedly during monsoons or batch discharges.*

  • Do you monitor sulfate in inlet & outlet monthly?
  • Is your ETP equipped with any anaerobic or anoxic zones?
  • Do you see corrosion or foul odour is sludge handling areas?
  • Have you tested sulfate levels in recycled water used for dyeing?
  • Are discharge limits being met consistently in the monsoon season?

If the answer is “ NO” to any of these, it’s time to review the sulfate removal strategy. Consult with us to get a comprehensive review and strategy today.

At Team One Biotech, we specialize in advanced sulfate removal from wastewater using proven technologies. Whether you’re dealing with high sulfate in textile, chemical, or pharmaceutical effluents, our solutions are tailored for high efficiency and long-term compliance.

Understanding BOD & COD: Beyond the Numbers
The real meaning of BOD & COD-Treat the problems, not the numbers

In the world of wastewater treatment, BOD (Biochemical Oxygen Demand) and COD (Chemical Oxygen Demand) are the most prominent parameters that are considered as pollution indicators. Treated as villains on an EHS dashboard—targets to be brought down, values to be minimized. But what do these numbers truly represent? What kind of organics do they qualify, and more importantly, who in the microbial world is responsible for bringing them down?

Many experts associate these with bod and cod in wastewater practices and their real impact on treatment efficiency.

Effluent treatment is not just a numbers game. It’s a microbial battleground—a complex “tug of war” between different microbial groups vying for pollutants/substrates, adapting to environmental pressures, and working together (or competing) to mineralize organics. In this blog, we explore the microbiological nuances behind bod and cod removal, how substrate complexity affects microbial degradation, and why a high COD isn’t always as alarming as it appears.

Understanding BOD and COD analysis can help in refining real-time operations and system design. Reach out to us to discover how advanced microbial solutions can optimize BOD and COD reduction while improving overall treatment efficiency.

The Basics: What BOD and COD Really Measure?

Before we dive into the microbial dynamics, let’s clarify the distinction.

BOD (Biochemical Oxygen Demand) is the amount of oxygen aerobic microbes require to degrade the organic matter, while COD (Chemical Oxygen Demand) quantifies the total oxygen equivalent required to chemically oxidize all organic matter (biodegradable + non-biodegradable) using a strong oxidizing agent like potassium dichromate.

These two are the cornerstone parameters in industrial wastewater treatment systems and compliance monitoring.

BOD < COD always, because COD includes organics that microbes simply cannot digest or take longer to degrade.

The bod cod ratio offers deeper insight into treatment feasibility and system design.

From an EHS perspective: High COD indicates total organic pollution load, while high BOD reflects readily biodegradable organics. Both values are essential to understand how much pollution is treatable biologically and what might need polishing steps or advanced oxidation.

Tracking wastewater parameters like BOD and COD regularly can optimize the sewage treatment process.

Microbes on the Frontline: Who Eats What?

In biological treatment, different microbes have different dietary preferences. Let’s break down the microbial players and the type of organics they typically handle:

Microbe Type Preferred Substrates Typical Zone
Heterotrophic bacteria Simple organics: sugars, alcohols, VFAs Aerobic & Anoxic
Autotrophs (e.g., nitrifiers) Ammonia and nitrite (not BOD/COD reducers) Aerobic
Facultative bacteria Complex and simple organics Facultative zones
Anaerobic consortia Proteins, lipids, cellulose (via hydrolysis → VFAs) Anaerobic digesters
Fungi Lignin, dyes, complex non-biodegradable organics Low-pH, low-DO

These microbial consortia play a vital role in bioaugmentation and microbial treatment in wastewater.

The ability of microbes to remove BOD and COD depends heavily on the complexity of the organic compounds:

  • Simple organics (low molecular weight): Easily removed in an activated sludge or aerobic digestion process.
  • Complex organics (e.g., phenolics, surfactants, dyes, oils): Require anaerobic process and longer retention time.

Effective treatment starts by understanding the organic load in wastewater and choosing the right microbial tools.

Substrate Complexity: Why It Matters

Not all COD is equal. Consider this:

A sugar-rich food processing effluent with COD 6000 ppm may have a BOD/COD ratio of 0.8 – meaning most of it is biodegradable.

A dye-laden textile effluent with the same COD might have a BOD/COD ratio of 0.2—signifying poor biodegradability.

Such complex effluents need multi-stage biological systems or pre-treatment with specific cultures.

Key Insight:

The BOD/COD ratio is a more insightful metric than standalone COD. Ratios:

  • 0.6: Easily biodegradable
  • 0.4–0.6: Moderately biodegradable
  • <0.4: Poorly biodegradable; may need physico-chemical treatment

In wastewater management, this ratio informs engineers whether nutrient removal or advanced oxidation is required.

Why High COD Isn’t Always Bad?

Let’s bust a common myth:

“High COD = Bad effluent” is not always true.

Imagine a brewery effluent with COD 20,000 ppm. That’s high, but it’s primarily from sugars, alcohols, and yeast residues—all highly biodegradable. A well-seeded biological reactor can bring it down to <200 ppm BOD with minimal retention time.

This shows how biodegradable wastewater with high COD still allows for efficient treatment if the microbial ecosystem is well-managed.

The issue isn’t how much COD, but:

  • What kind of organics are present?
  • Are they toxic to microbes?
  • What is the system design (anaerobic first, aerobic polishing, etc.)?

This is where environmental monitoring and EHS in wastewater become indispensable.

Winning the Microbial Tug of War

If COD removal is a tug of war, here’s how to tip the balance:

  • Pre-treatment & Equalization: pH adjustment, oil & grease removal, and flow equalization prevent microbial shocks.
  • Segmented Treatment Zones: Anaerobic → Anoxic → Aerobic → Polishing ensures sequential degradation of complex substrates.
  • Use of Custom Biocultures: Tailored microbial blends (like lignin-degraders or surfactant–eaters) enhance specific removal.
  • Nutrient Balancing: C:N:P ratio is essential. Too much carbon without nitrogen/phosphorus slows down microbial growth.
  • Monitoring & Feedback: Online DO, ORP, and real-time COD analyzers help in dynamic adjustment

Each of these is critical for maintaining optimal microbial load and ensuring full biological oxygen demand reduction.

Final Thought: Treating the Problem, Not Just the Number

COD and BOD are not just compliance metrics—they are windows into the microbial and chemical world inside your ETP. A high COD is only dangerous if:

  • It overwhelms the biological system
  • It contains toxins
  • Or it is mismanaged

With the right microbial consortia, proper process staging, and continuous EHS vigilance, even high-COD effluents can be efficiently treated—transforming a ‘problematic’ effluent into a sustainable output.

This makes bod cod full form far more than a definition—it’s a philosophy for modern types of wastewater management.

After all, in the tug of war between pollution and treatment, it’s the micro-warriors who win it for us—if we give them the right battlefield.

Sludge Bulking vs. Sludge Settling Ways to improve wastewater treatment in India
Sludge Bulking vs Settling: Biotech Companies in India

“Our MLSS is quite high, but we are not getting enough settling. “ or “Our biomass development is very good as our MLSS is high, but we have very little BOD/COD reduction”. these statements are often given by EHS managers. However, the concept of MLSS is completely misunderstood; it’s never the quantity of MLSS, it’s always the quality of MLSS. The settling of sludge and BOD reduction always correspond with how good the MLSS is, and not how much it is.

This blog intricately explains the difference between sludge bulking and sludge settling, and which factors are necessary to look out for.

Sludge Settling vs Sludge Bulking:

With the growing awareness of operational efficiency, several biotech companies in India are now addressing sludge bulking challenges through microbial innovation and advanced diagnostics.

Healthy Sludge Settling:

In a well-operating secondary clarifier, biomass flocs are compact, dense, and settle rapidly. The supernatant above appears clear, and the sludge blanket remains stable.

Sludge Bulking:

Here, the sludge appears fluffy, loose, and struggles to compact at the bottom. The supernatant turns turbid, and sludge blankets may rise or disperse.

Parameter Healthy Settling Sludge Bulking
SVI (Sludge Volume Index) 80–120 mL/g >150 mL/g
Sludge appearance Dense, compact flocs Loose, filamentous flocs
Supernatant Clear Turbid
Settling time 20–30 mins >45 mins
Cause Balanced system Filamentous overgrowth, F/M imbalance
Why Good MLSS ≠ Good Settling

Operators often celebrate high MLSS as a sign of strong microbial population. But MLSS is a mass reading-It doesn’t distinguish between healthy floc-formers and problem-causing filamentous organisms.

“ Think of it like body weight: Two individuals weigh the same, but one may be with lean muscle, the other with excessive fat.

In bulking scenarios, the bulk of MLSS is held together by filamentous bacteria-these long, thread-like organisms stretch out of flocs, creating open, web-like structures that trap water and resist compaction.

Reliable biocultures companies have been instrumental in developing floc-forming microbial strains specifically tailored for bulking control.

What Causes Sludge Bulking?
  1. Filamentous Bacteria Overgrowth

Common species: Type 021N, Sphaerotilus, Microthrix parvicella, Thiothrix

These bacteria thrive under specific conditions such as:

Low DO (<1.0 mg/l) – especially at floc centers.

High F/M ratios – excess food leads to dominance of fast-growing filaments

Nutrient Imbalance– N and P deficiency affect floc formation

Surfactants and FOG – common in food, dairy, and textile industries

Hydraulic surges – shock loading from upstream process

Leading microbial companies in India are providing industry-specific solutions for complex ETP issues, helping clients achieve consistent results in variable conditions.

 

  1. F/M Ratio Imbalance

Too much organic load relative to MLSS results in excessive microbial growth, and filamentous bacteria often outcompete floc-formers.

Ideal F/M ratio: 0.2-0.5 kg BOD/kg MLSS/day

Bulking is more likely when F/M > 0.6 or < 0.1, especially during inconsistent feed conditions.

  1. pH and Toxic Shocks

Sudden changes in pH (below 6.5 or above 8.5) , or toxic loads (solvents, phenols, metals) can kill floc-formers and allow filaments to dominate during regrowth. However, Solutions like those from Team One Biotech, a known player among bioculture for ETP STP plant manufacturers, are reshaping how industries manage MLSS health and sludge behavior.

 

Decoding SVI and other key Indicators

Sludge Volume Index (SVI) is the gold standard for assessing settleability.

  • SVI = ( Settled sludge volume in 30 mins, mL/L) / MLSS (g/L)
  • SVI < 100 = Good settling
  • SVI 120–150 → Early warning of bulking
  • SVI > 200 → Severe bulking

Other red flags:

  • Rising sludge in the clarifier
  • Scum layer formation
  • Poor TSS in final discharge
  • Varying DO and pH patterns in aeration tanks
Countermeasures- How to fix Bulking?

In addition to microbial solutions, industrial odor control systems  also play a pivotal role in overall ETP performance and workplace hygiene.

Short-Term Fixes:

  • Chlorination or Peracetic Acid Dosing: Targets filamentous bacteria selectively. Start with 0.5–1 ppm, monitor response.
  • Increase DO Levels: Maintain >2.0 mg/L throughout the aeration tank, especially in large tanks or tanks with dead zones.
  • Sludge Wasting: Reduce SRT (sludge retention time) to control filament growth. Remove excess MLSS.
  • Polymers in Clarifier: For emergency clarity issues, short-term use of cationic polymers can compact sludge.

Long-Term Solutions:

  • Nutrient Balancing: Maintain COD:N:P at approx. 100:5:1. Add urea or DAP if needed.
  • Equalization Tank: Smooth out hydraulic/organic loading rates to the aeration tank.
  • Bioculture Regeneration: Consider seeding with robust floc-forming consortia after bulking episodes.
  • Upgrade Aeration: Switch to fine-bubble diffused aeration systems to improve oxygen transfer.
  • Micronutrient Support: Trace metals like iron, cobalt, and molybdenum support healthy floc formers.

If you’re exploring biocultures for ETP plant manufacturers in India or need effective bacteria solutions for wastewater treatment, Team One Biotech offers proven blends tested across sectors.

Conclusion:

Remember one quote: What settles well, treats well. MLSS and BOD tell only one part of the story – settleability, floc health, and microbial balance complete the picture.

As experts and EHS leaders, we must look beyond the dashboard. A 3500 mg/L MLSS might impress, but if your sludge floats and supernatant clouds, your ETP is already sending you a warning.

Anaerobic Wastewater Treatment: Demystifying Methanogenesis
Anaerobic Wastewater Treatment: Demystifying Methanogenesis

The wastewater treatment world is an unending sea of types of processes and variations. One such process, the anaerobic treatment, holds a prominent and popular reputation due to its low CAPEX-OPEX and generation of byproducts such as methane, which is valuable as well as a clean energy source.

The process that leads to methane production is known as methanogenesis-which is the final and slowest step in the anaerobic digestion chain, where intermediate acids and hydrogen are converted into methane.

However, the process is mostly underperforming in the industries due to its bottlenecks and variable mechanism. This blog helps readers understand the intricacies of methanogenesis and helps understand the concept and mechanism.

In the rapidly evolving landscape of anaerobic wastewater treatment, industries are recognizing the limitations of traditional systems and turning toward advanced, high-efficiency strategies. With increasing load from industrial effluent treatment, especially containing high COD and toxic compounds, the need for anaerobic bioreactor optimization is more critical than ever.

With the increasing demand for bacteria solutions for wastewater treatment, industries are actively seeking partners who understand both biology and process engineering.

Companies like Team One Biotech lead the way among bioculture companies and microbial companies in India, delivering high-performance strains suited for industrial ETPs.

We provide expert consulting and microbial formulations tailored for anaerobic systems. Contact us today to learn more about our solutions and transform your treatment process.

What is Methanogenesis?

Methanogenesis is the last step in anaerobic digestion, where the end products from acetogenesis and acedogenesis process are converted into methane gas and CO2 by methanogenic archaea.

Modern facilities strive for not just compliance but profitability through biogas production efficiency, transforming waste streams into energy assets. The use of engineered microbial consortia, such as T1B Anaerobio, ensures higher methane recovery from wastewater even under challenging conditions like salinity and shock loads.

Core stages of Anaerobic Digestion:

  1. Hydrolysis: Breakdown of complex organics (proteins, carbs, Fats)
  2. Acidogenesis: Fermentation into VFAs (volatile fatty acids), alcohol, H2.
  3. Acetogenesis: Conversion of VFAs into acetate, H2, and CO2.
  4. Methanogenesis: Final step producing CH4 and CO2.

Types of methanogens:

Pathway Microbial Group Substrate
Acetoclastic Methanosaeta, Methanosarcina Acetate → CH₄ + CO₂
Hydrogenotrophic Methanobacterium, Methanococcus H₂ + CO₂ → CH₄

 

These microbes are obligate anaerobes, extremely sensitive to environmental shifts-and incredibly slow-growing.

Why does methanogenesis often fail?

As evident, it is important to have success in all three processes i.e. Hydrolysis, Acidogenesis, and Acetogeneis, before Methanogenesis  to succeed. This requires proper management of pH, temperature, HRT and induction of right biomass. However, in most cases all the three preceding processes are comparatively easier to get executed, it is this methanogenetic process only where most plants struggle due to:

  1. Acid accumulation/VFA Buildup
  • Acidogenesis is rapid, while methanogenesis is slow.
  • Result: VFA overload, which causes pH to drop below 6.8—a toxic zone for methanogens.

 

  1. Toxic Inhibitors

Common industrial effluents contain:

  • Heavy metals (Zn, Cu, Cr)
  • Sulfides
  • Phenols
  • Ammonia >2000 mg/L

These compounds directly inhibit methanogenic enzyme systems.

  1. Salinity and TDS stress

TDS above 15000-20000 ppm imposes osmotic stress, especially on Methanosaeta, which is already slow-growing.

 

  1. Lack of Granular Structure in Reactors

Granules in the sludge allow the methanogens to thrive in micro-environments.

  • Poor granulation = less protection = washout
How to Improve Methanogenesis- Practical Strategies

Improving methanogenesis requires a holistic approach involving operational tuning, microbial reinforcement, and environmental stability.

  1. Maintain Optimal pH: 6.8 – 7.4

Methanogens are extremely pH sensitive; any fluctuation can halt the methanogenic process that leads to unwanted reverses.

  1. Control Organic Loading Rate (OLR)

Gradually ramp up OLR during commissioning, ideal OLR: 1.5-3.5 kg COD/m3/day for stable systems. Overfeeding typically leads to acid overload and ultimately methanogen collapse.

  1. Ensure Adequate Retention Time

The ideal HRT should be between 8-15 days (depending on the substrate). The SRT should be even longer in high-loading systems.

  1. Use advanced Biocultures enriched in Methanogens

Key Traits of Effective Methanogenic Biocultures:

  • Contains both acetoclastic and hydrogenotrophic strains
  • High cell viability in anaerobic, low-oxygen environments
  • Pre-adapted to shock loads, high COD, and salinity

At Team One Biotech, our T1B Anaerobio blend includes halotolerant Methanobacterium and facultative syntrophic partners that stabilize early acid-phase products and prevent VFA accumulation.

  1. Add Conductive Materials (Bio-Stimulation)
  • Use activated carbon, biochar, or magnetite in digesters.
  • These promote direct interspecies electron transfer (DIET), bypassing slower H2 pathways
  • Result: Faster methanogenesis and increased CH4 yield
  1. Control Sulfates and Heavy Metals

 Sulfate-reducing bacteria (SRB) compete with methanogens for substrate.

  • High sulfide also directly poisons methanogens
Key Indicators of Methanogenesis Health
Parameter Healthy Range
pH 6.8 – 7.4
VFA/Alkalinity ratio <0.3
ORP -300 to -400 mV
Biogas CH₄ content >60%
Foaming Minimal (indicates balance)
Gas production rate Steady increase or plateau
Methanogenesis is Fragile, but Fixable

Methanogenesis is the most sensitive yet rewarding step in anaerobic treatment. It’s where the “waste” becomes “resource,” and the environmental liability transforms into a clean, combustible asset.

But to get there, industries must move beyond legacy systems and general-purpose biology.

They must:

  • Understand the microbial bottlenecks
  • Deploy engineered or acclimated methanogens
  • Support them with pH buffering, controlled feeding, and granular retention

Only then can your anaerobic system realize its full potential — both in COD removal efficiency and renewable methane production.

Conclusion:

Achieving high COD removal technology performance depends heavily on maintaining organic loading rate control, optimal pH, and reducing VFA accumulation. Furthermore, granular sludge formation enhances microbial retention and process stability, which is vital in high-strength wastewater treatment systems.

Through targeted bioaugmentation for anaerobic digestion, enriched with salinity resistant methanogens, it’s now possible to manage volatile environments and optimize yield. These microbial consortium for ETP solutions include both acetoclastic and hydrogenotrophic archaea, enabling efficient conversion pathways and reduced inhibition.

One promising method includes introducing conductive material in digesters, which boosts DIET and facilitates faster VFA to methane conversion. This, combined with proper HRT/SRT balance and T1B Anaerobio application, unlocks new levels of process performance.

As we progress towards zero-waste water solutions and advanced ETP solutions, methanogenesis is no longer just a biological reaction—it’s a cornerstone of sustainable industrial practice.

In recent years, several biotech companies in India have made significant strides in anaerobic treatment technologies, offering customized microbial formulations.
