industrial holidays Anaerobic Wastewater Treatment in Industries
The effect of industrial holidays on ETP health

The ecosystem of industries is complex as well as consistent. However, shutdowns due to festivals, season, operational failure, or force give a halt to the whole system. Although mostly planned, these industrial holidays are intended to give relief, but deep down in the concrete basins of effluent treatment plants brews a storm of crisis, whether it may be in the primary, secondary, or tertiary systems.

Looking for expert solutions to manage ETP shutdown challenges? Contact Us today for tailored advice and services!

And if we focus on the secondary system, the microbial population gets the worst hit. This blog focuses on what happens inside the secondary system during an industrial holidays, its effects, precautions, and prevention.

The living Microbial world of ETP:

The secondary system is like a society where microbial populations i.e, bacteria, fungi, yeast, metazoans etc. thrive on:

Food: Readily biodegradable organic matter.

Shelter: Biofilms, flocs, or suspended habitats.

Environmental Comfort: pH, temperature, DO, and nutrients in a narrow optimal range.

Maintaining microbial diversity and stability is crucial for consistent ETP performance.

Microbial Starvation- A Hidden Shutdown Crisis

A 10-15 day shutdown without influent feed creates what we call a starvation phase in the bioreactor. The period can trigger several microbial stress responses:

Autolysis Begins:
  • Without food, heterotrophic bacteria begin digesting their own cellular reserves.
  • When reserves run out, cell walls rupture, releasing intracellular enzymes and ammonia into the mixed liquor.
Shift in Community Structure:
  • Fast-growing, high-COD degraders die off first.
  • Resilient microbes like filamentous bacteria and nitrifiers may survive longer, but their metabolic activity drops drastically.
Dissolved Oxygen (DO) Becomes Redundant:


  • With no substrate to oxidize, aeration continues but becomes wasteful.
  • High DO levels can paradoxically stress certain facultative anaerobes used to fluctuating oxygen levels.


MLSS/MLVSS Decline:
  • The Mixed Liquor Volatile Suspended Solids (MLVSS)- the biologically active portion of MLSS drops due to decay.
  • Settling characteristics deteriorate, and the SVI (Sludge Volume Index) can spike due to deflocculation.
Recovery is Not Instant – The Myth of “Rest and Run”

When production resumes, many assume the ETP will bounce back like a machine switched on. But biological wastewater treatment systems have no reset button.

Lag Phase in COD Reduction
  • Microbial populations take time to rebuild numbers and enzyme systems.
  • Expect 2-5 days of poor performance and higher COD/BOD in the outlet, especially in systems with no pre-seeding plan.
Sludge Age Misbalance
  • Sludge that has aged during the shutdown may have lost its settling efficiency.
  • Decayed sludge may also release toxins and nutrients, creating internal loading.
Shock Loads on Restart
  • Sudden reintroduction of full-strength effluent can lead to shock loading.
  • This exacerbates foaming, odor, and even system upset.
Preventive Measures

ETP health during shutdowns doesn’t have to be a gamble. Here are proven strategies, drawn from both research and field practices.

1.Feed Synthetic System:
  • Use glucose, molasses, milk whey, or diluted Urea/COD substitutes to mimic organic load at low levels (10-20% of actual COD).
  • Feed once or twice daily to maintain microbial respiration and floc integrity.\
2.Aerate intermittently:
  • Continuous aeration is wasteful. Instead, apply 4-6 hours/day intermittent aeration to maintain DO and prevent anoxic.
3.Monitor pH and ORP
  • During starvation, microbial metabolism can skew pH or ORP. Keep these in range to avoid unfavorable drift.
4.Bioaugmentation on Restart
  • Introduce high-count commercial biocultures tailored to your effluent type. This accelerates recovery.
  • Use starter cultures or preserved sludge from pre-holiday if available.
5.Sludge Management 
  • Remove aged or decaying sludge before shutdown. 
  • During long holidays, periodic recirculation or RAS/WAS adjustments prevent septic conditions.
Maintaining ETP Efficiency During Industrial Holidays with Bioculture Support

When industrial units pause operations during holidays, the ETP treatment process often slows down due to the absence of organic load. Microbes inside the aeration tank gradually lose activity, leading to poor degradation once the plant restarts. That’s where a bioculture for ETP operations becomes critical — it revitalizes the microbial community, improves resilience, and stabilizes performance without costly chemical interventions.

During downtime, parameters like ETP sludge volume, dissolved oxygen, and pH can fluctuate drastically. A pre-dosage of selected microbial strains helps maintain a balanced environment and prevents sludge bulking or odour generation. When operations resume, the system achieves faster recovery and reduced start-up lag.

To ensure long-term system reliability, work with trusted ETP plant manufacturers in India who understand the importance of integrating biological solutions into design. Many modern ETP and STP systems now include dedicated dosing points for microbial formulations and smart monitoring dashboards that track ETP standard parameters such as BOD, COD, TSS, and MLSS.

Whether you operate a textile, chemical, or food processing unit, maintaining your ETP treatment plant during holidays means safeguarding compliance and avoiding post-shutdown surges in effluent load. Explore how Team One Biotech’s Bioculture Solutions ensure consistent ETP water treatment efficiency even under variable operating conditions.

Both resources complement this article by showing how bioculture for ETP transforms operational challenges into measurable efficiency gains.

Conclusion:

Industrial holidays are an unavoidable part of operations across industries such as textiles, pharmaceuticals, and chemicals and can’t be avoided but the problems related to it in an ETP can surely be avoided by taking the right steps, proper planning, and taking proactive measures.Investing in bioaugmentation, sludge handling, and strategic aeration ensures microbial resilience during shutdowns.

Replacing Urea-DAP in a Textile Industry
Introduction:

We, at Team One Biotech LLP, help industries achieve sustainability goals with our biological wastewater treatment solutions, offering natural replacements for chemicals like urea-DAP and other nutrients.

In this success story, we are going to walk through the treatment efficiency and results achieved using SustainX for a leading textile company located at Dabhasa, GIDC, Gujarat. If you want to know more, feel free to contact us. 

The industry happens to be one of the most compliant and efficient in terms of textile wastewater treatment, they had a very good ETP mechanism and trained staff. However, they had a huge consumption of UREA-DAP, leading to high OPEX, also they used to experience sudden spikes in Ammoniacal nitrogen values during winters.

ETP Flow chart:

Primary- Biological and Tertiary systems, with RO & MEE. The activated sludge process (ASP) has 3 aeration tanks in series and one anoxic tank before the aeration tanks. 

Flow:1500 m3/day
Inlet COD:8,000 to 12,000 ppm
Inlet Ammoniacal Nitrogen:280 to 320 ppm
COD outlet after biological treatment:  1800 to 2500 ppm
Ammoniacal Nitrogen after biological treatmeent120 to 170 ppmDuring Spike: 200-250 ppm
Urea – DAP consumption800 kgs/day – 400 kgs/day respectively
Challenges:

Why traditional nutrients are inefficient in ETPS:

The commonly used urea and DAP are often overused in industrial treatment plants and they limit bioavailability for microbes. This results in poor nutrient uptake in biomass and limitations in COD and nitrogen removal causing ammonia spikes disturbing overall textile wastewater treatment systems.

1.The F/M ratio was low due to heavy consumption of UREA-DAP, leading to higher OPEX.

2.Sudden spike in ammoniacal nitrogen levels, especially in winters, due to non-consumption of ammonia from these fertilizers.

3.Saturation in COD is degrading efficiency.

The Scrutiny:

After a complete study of the plant through our WWTP evaluation form, on-site visits, and discussions with the EHS team, we concluded:

1.The F/M ratio gets lower if we stop urea-DAP addition.

2.The spike in ammoniacal nitrogen was due to the higher concentration of non-available nitrogen in the aeration tank, which was not absorbed by the biomass.

3.The indigenous microbial population was only performing at 60% efficiency in terms of COD reduction due to lower nutrient absorption despite a heavier dosage of UREA-DAP.

The Approach:

How T1B SustainX Works Better Than Urea-DAP:

SustainX is enriched with the naturally derived formulations comprising organic carbon and essential nutrients. It accelerates microbial metabolism and enhances organic waste degradation. Its unique formula helps eliminate side effects of urea and DAP and stabilizes the ammonical nitrogen. SustainX has proven benefits of optimising F/M ratio.

1. Product Selection:

Thermophilic vs Mesophilic Anaerobic Wastewater Treatment in Industries

The anaerobic treatment of wastewater heavily relies on trends, and unfortunately, adaptation and innovation are very slow in progression compared to rising pollution. 

Although we are all talking about the use of AIs, sensors, IOTs, and efficient hardware, unfortunately, when we consider the industrial wastewater treatment,and broader industrial effluent treatment, we are still stuck at the same processes we were 30 years ago. If you would like to know how we are optimising wastewater treatment methods in diverse environments, feel free to connect with us today.

There needs to be a continuous update at the process level, because 99 % anaerobic plants are mesophilic, i.e, work at a temperature of 30-38 *c. In regards to biocultures for wastewater treatment, the mesophilic treatment is prominent; however, the thermophilic treatment is much more effective and compatible. 

Although it is an uncommon type of ETP water treatment, when it comes to tough-to-degrade effluents such as those with recalcitrant COD, or those with phenols, Aldehydes, etc., the thermophilic microbes treatment can be a game changer in anaerobic digestion.

This blog explores when it makes sense to shift from mesophilic to thermophilic wastewater systems, the practical advantages and challenges, and what it means for plant operators and environmental engineers.

Let us start with the basics:

Parameter Mesophilic (30–38°C) Thermophilic (50–60°C)
Microbial growth rate Moderate High
Biogas yield Moderate Higher (10–25% increase)
Pathogen kill Limited Excellent (>99%)
Energy input required Lower Higher
Process stability High Sensitive to changes
Start-up time Shorter Longer

The core of the thermophilic system lies in its high-energy fast result mechanism. The hydrolysis process is much faster, resulting in increased metabolic rate and superior pathogen control in biological wastewater treatment.

Issues where thermophilic treatment can be effective:
  1. High-Strength Industrial Wastewaters:

Effluents from industries such as dairies, food processing, slaughterhouses, distilleries and starch industries have higher levels of protiens, lipids, and polysaccharides. Thermophilic systems hydrolyze and degrade these faster, leading to:

  • Higher COD, BOD degrading efficiency.
  • Higher biogas production
  • Shorter HRT (hydraulic retention time)
  • Enhanced treatment of high-strength wastewater

2. Excess Sludge and Biomass Handling Issues:

  • While most mesophilic anaerobic systems produce higher sludge, the thermophilic system produces lower quantities of excess sludge and reduces volatile solids.

3. Strict Pathogen and Odor Control: 

  • The thermophilic systems give 99% pathogen elimination in STP/Centralized ETPs that handle fecal sludge or pathogen prone waste, which is crucial if:
  • Sludge is reused in agriculture
  • Water is recycled for non-potable uses
  • Especially relevant for optimized wastewater microbiome management

4. Waste Heat:

  • In case of high waste steam, condensate, or cogeneration (CHP) units, the thermal energy can be internally sourced.
  • This supports efficient energy recovery within the plant
Microbial Diversification: Fragility Meets Efficiency

In case of the microbial cultures for wastewater treatment, the thermophilic microbes are completely different from mesophilic ones. Although thermophiles are fewer but are formidable with higher metabolic abilities in the organic waste degradation.

Key Observations:

  • Thermophilic methanogens are more sensitive to pH, VFA spikes, and loading rates.
  • Shock loads (especially of fats, solvents, or salts) can cause faster crashes.
  • Granular sludge formation is more difficult at thermophilic temperatures; biofilms or hybrid systems are better suited.
Biogas enhancement: Quantitative and Qualitative

Thermophilic systems offer 10-25 % higher biogas yield per unit COD removed. More importantly, the methane content is often higher (up to 70-75%) compared to 60-65% in mesophilic digestion.

This makes the Thermophilic process enticing where:

  • On-site biogas is used for power/steam
  • Fossil fuel replacement is a business or ESG goal
  • Carbon credit mechanisms or green energy policies apply
  • Also aligns with zero liquid discharge (ZLD) and carbon neutrality efforts
Operational & Engineering Challenges in sewage treatment process

1. Temperature maintenance:

Temperature maintenance is the key of thermophilic processes, which is altogether challenging both technically and economically, especially in large tanks and in colder environments. 

2. Narrower process Window

Thermophiles work in a smaller range.  Any variation in:

  • pH (ideal: 7.2-7.6)
  • Alkalinity ratio (IA/TA < 0.3 )
  • VFA accumulation

Can lead to performance drops

3. Start-Up Lag

Thermophilic start-up can take 30-60 days, requiring:

  • Seeding with adapted sludge
  • Step-wise temperature ramping
  • High monitoring effort

4. Foaming & Scum

Due to high gas production and surfactant sensitivity, thermophilic systems foam more easily, especially during acidification.

Know the Process, Not just the Temperature:

To be precise, a thermophilic system is not for every ETP (Eluent treatment plant), however, it is effective for any ETP where it is applied. It no doubt is high energy, difficult in operations, and with fragile microbial populations, but it always outpaces mesophilic treatment in COD/BOD control, methane gas production, and cleaner sludge.

et, it’s not a plug-and-play upgrade. You must rethink your sludge management, monitoring protocols, nutrient balancing, and energy integration.

The question isn’t whether thermophilic digestion works—it’s whether your plant is ready to manage the precision and potential that comes with it.”

If you’re designing or upgrading an anaerobic system and want to make it future-proof—especially for energy recovery or zero-liquid discharge (ZLD) ambitions—don’t ignore the thermophilic path. Just walk it carefully.

Toxic Shockwaves Travel Through ETPs How to Deal
How Toxic Shockwaves Travel Through ETPs: A Deep Dive into Impact, Zone-Wise Failure, and Recovery

A sudden or abrupt change from regular mechanisms, schedules, habits, or play is detested everywhere, right from living to non-living beings and from nature to industries or the metropolis.  These sudden changes sometimes come with the signs of change that, if identified at the right time, either prevent or make one prepare. But not all thunders come up with lightning.

Here, as we talk about wastewater treatment in ETPs, shock loads remain one of the most common and feared issues.With the onset of shock loads or the sudden introduction of a toxic system with lethal compounds leads to complete disarray in the system, and the whole microbial population gets attacked and damaged and it a tough task to reboot it and get it back to its normal stage.

However, if we know how toxic shockwaves in ETP travel in different systems and what signs the system produces before and during the onset, we can empower us to control this unwanted phenomenon.???? Need expert support in handling or preventing toxic shockwaves in ETP? Contact our team at TeamOne Biotech for consultation, solutions, and support.

Let’s explore the shockwave travel mechanisms, early signs of warning, zone-wise failure and how to recover.

What is Toxic Shock ?

A sudden short-terms ingress of physical or chemical conditions that disrupts routine mechanisms an d disrupts microbial populations.

The Culprits: Common Toxic Agents:

  • Heavy metals (e.g., Cr⁶⁺, Zn²⁺, Cu²⁺): Inhibit enzymes and damage membranes.
  • Phenols and aromatic solvents: Disrupt cell walls, denature proteins.
  • Quaternary ammonium compounds (QACs): Destroy microbial membranes.
  • Strong acids or alkalis: Denature enzymes and destroy extracellular polymeric substances (EPS).
  • High TDS or salts: Cause osmotic shock, dehydration of microbial cells.
  • Temperature spikes: Above 40°C can be lethal to most ETP microbes.

A high COD  is not always directly proportional to toxicity. Even in a batch with COD of 2000 ppm, a 50 ppm phenol will cause disruptions.

How do toxic shockwaves in ETP travel through each zone?

1.Anaerobic Zone:

The anaerobic digestors or UASB reactors break down organics into methane or carbon dioxide by acidogenic and methanogenic bacteria.

The Effect of Toxic Shock:

Methanogens are more prone to shock as they are highly sensitive to pH shifts, metals, and aromatic solvents. A toxic load here may: 

  • Kill methanogens outright, collapsing methane production.
  • Lead to accumulation of VFAs (volatile fatty acids), crashing the pH below 6.5.
  • Result in black sludge, gas bubbles, and floating scum layers.
Indicators:

  • Drop in biogas flow rate (if monitored).
  • pH drop in digester effluent.
  • Sulphide-like odor and gas toxicity.
  • Foaming or bubbling at inlet distribution zones.
Recovery Options :

  • Stop influent flow immediately
  • Neutralize VFAs to bring pH back to 7.2 to 7.6
  • Inoculate with fresh anaerobic bioculture.
  • Feed diluted influent after 3-5 days of stabilization
2.Anoxic Zone: The Invisible Impact Zone

The function of the anoxic zone is highly dependent on nitrifying and denitrifying bacteria. 

The Effect of Toxic Shock:

Denitrifiers are facultative—more robust than methanogens—but still impacted by solvents, surfactants, and metals.

  • Nitrate remains unreduced.
  • Partial reduction leads to nitrite accumulation, which is also toxic.
  • Disruption in redox balance halts nitrogen removal.
Indicators:

  • Rising NO₃⁻ or NO₂⁻ in secondary-treated water.
  • No bubbles or gas generation from the anoxic tank surface.
  • Slight odor of chlorine or nitric oxide due to nitrite oxidation.
  • No apparent foaming or color change—this failure is usually silent.
Recovery Options :

  • Supplement the carbon source ( eg, methanol or acetate ) to restart denitrification.
  • Check and adjust DO and ORP to stay below 0.3 mg/L and -100 to -300 mV, respectively.
  • Restart mixing gently—denitrification is sensitive to turbulence.
3.Aerobic Zone: 

Aerobic microbes (heterotrophs, nitrifiers) oxidize organics and nitrogen, producing CO₂, nitrate, and water.

The effect of Toxic Shock:

It is comparatively easier to identify shocks easily in Aerobic Zones:

  • Increase in soluble COD and turbidity due to Cell lysis.
  • Release of ammonia and phosphates into the water.
  • Poor settling followed by clarifier overflows due to the disintegration of flocs.
  • Pathogen population surge due to collapsed microbial competition.
Indicators:

  • Septic-like: conditions-black, greasy foam with foul smell.
  • A sharp increase in SVI.
  • Filamentous and Nocardia become prominent.
  • Sudden DO depletion even with aeration on.
Recovery:

  • Stop the influent
  • Maintain DO at 3-4 mg/l
  • Slowly start the hydraulic load with 25-30% for the first 5-6 days and then gradually increase.
  • Waste heavily to remove lysed or decayed biomass.
  • Start adding bioculture with robust and shock-tolerant bacteria.
System-Wide Effects Ripple effects:

Secondary Clarifier:

  • Overloaded with dispersed solids → turbid effluent.
  • Sludge blanket floats or rises.
  • Polymer usage increases for sludge settling.
Sludge Dewatering:

  • Decayed biomass becomes non-dewaterable.
  • Centrifuges and belt presses clog easily.
  • Sludge has high moisture content and low calorific value.
Tertiary Treatment:

  • UF/RO membranes foul rapidly with organic colloids.
  • Sand filters choke with fine, dispersed flocs.
  • Chemical dosing (PAC, alum) surges.
Recovery Timeline Framework

PhaseActionTypical Duration
Initial ArrestStop feeding, start aeration, dose buffers0–24 hours
StabilizationAdd bio-culture, monitor parameters1–3 days
Gradual LoadingResume with diluted or treated influent4–7 days
Full RecoveryReturn to design load with full microbial function7–15 days
Conclusion:

AN ETP is like a living ecosystem with uncertainties. If we can find our early warning signs, we can prevent the discrepancies arising due to toxic shock waves in ETP. Although it is a very tough scenario to tackle but if prevented in time, the chances of vulnerability become very less.

Phosphate Removal in a Chemical Manufacturing Plant in Madhya Pradesh

A prominent chemical manufacturing unit situated in MP near Ratlam is our existing client to whom we provided technology to treat high COD and TDS effluent. They again approached us due to their experience working with us. They wanted to treat an effluent stream with high phosphate content upto 1500-2000 ppm. They asked us to use their old ETP, revive it , commission and make it efficient for phosphate treatment.

Looking to optimize your ETP for phosphate treatment, COD, or BOD removal?

Contact us to explore the right biological phosphorus and removal technologies for your industry!

1st Phase: Scrutiny

Our team of experts visited the factory to introspect and identify scope of improvements.

OLD ETP details:

The ETP had primary treatment, biological treatment (Anaerobic), and then a tertiary treatment.

Flow (current)350 KLD
Type of processUASB
No. of UASBR1
Capacity of biological tank950 KL

Parameters of the stream with Phosphate:

Parameters Avg. Inlet parameters(PPM)
COD4300
Phosphate Content1500-1800
TDS3000

2nd Phase : The Blueprint

After scrutiny and brainstorming with our R&D, we concluded to transform the old ETP apparatus into an EBPR unit, i.e., Enhanced Biological Phosphorus removal unit, which involves the introduction of PAOs (polyphosphate-accumulating bacteria) into the biological system along with physico-chemical treatment in primary and tertiary systems, respectively, of the old ETP.

ETP process optimization:

An efficient EBPR unit requires anaerobic as well as aerobic system, as in anaerobic the RbCODs get transferred into VFAs, which are then absorbed by PAOs for efficient phosphate uptake, which is dispersed during the anaerobic process. The PAOs then absorb the phosphate rapidly in the aerobic system. Hence, biomass with phosphate-absorbed PAOs is allowed to settle in the clarifier, and then WAS is removed.

In this scenario, the ETP had a UASB system, but no Aeration system, hence:

  • We utilized a spare tank of capacity 300 KL located next to USABR, and transformed it into an aeration tank by installing diffusers.
  • After our recommendation, the industry installed a 50 KL FRP clarifier after the sedimentation system.

Thus, we converted the old ETP into a facultative EBPR unit with integrated biological phosphorus removal capability.

3rd Phase : Technology and Execution

1. Selecting biocultures:

For UASB:

T1B Anaerobio: 

T1B Anaerobio bioculture solutions for phosphate treatment

The perfect solution for an Anaerobic system consists of robust bacteria that can efficiently work in anaerobic conditions, leveraging efficiency in terms of:

  • COD reduction
  • Biomass Generation
  • Methane Generation
  • F/M ratio optimization

Here, since our goal was phosphate treatment and reduction, we amalgamated PAOs as well, which made the product extremely effective to be used in the developed EBPR system.

For Aerobic Tank:

T1B Aerobio:

T1B aerobio bioculture solutions for phosphate treatment

Equipped with highly robust and selective strains of bacteria which when combined with PAOs, made T1B Aerobio the best-suited weapons to remove phosphate levels, thereby increasing the efficiency of the EBPR unit.

2.Dosing:

Initially, we provided a dosing schedule for 60 days, in which 1st 30 days was loading dose, with a higher product quantity, and the second  30 days dose was maintenance dose, which was 1/4th of the loading dose.

ProductT1B AnaerobioT1B Aerobio
Loading Dose100 kgs60 kgs
Maintenance dose40 kgs20 kgs
Point of additionUASBAerobic Tank

3.Process optimization:

Our target was to achieve MLSS of 3500-4000 in the first 15 days. After that, the WAS was wasted at 15 KLD, and RAS was recirculated at 5 KLD.

Results:

After 60 days of implementation:

Parameters Primary OutletUASB OutletClarifier Outlet
COD39001900800
Phosphate1300-1500850-900180
COD Reduction10 %~ 55 %82 %
Phosphate reduction %8-10%~ 65 %~85-90%

Conclusion

With the combined effect of T1B Anaerobio and T1B Aerobio bioculture and process optimization, the client achieved an 85-90 % reduction through the biological system, which further increased after tertiary system. This translated into:

  • Improved microbial activity and settleability.
  • Stable effluent quality, meeting compliance standards.
  • Biocultures are effective in phosphate removal.

This case demonstrates how biology-driven solutions, coupled with system know-how, can deliver tangible performance and cost benefits in industrial wastewater treatment.

Phosphate Removal with Biocultures
The menace of Phosphate- How to deal with it using Biocultures?

Phosphates are one of the prominent water pollutants, as designated by the NGT in 2019. A Suo-motu cognizance was also taken by the NGT on detergents and especially phosphate accumulation in rivers and water bodies, causing toxic foam, algal deposition, and eutrophication. Phosphates also exert odour and color. Strict limits have been issued to control phosphate accumulation. However, at the wastewater treatment levels, phosphate removal is a bit tough job as it requires multiple stages, effective bioculture solutions, and technical expertise to do so. 

Although chemical and physical separation are essential, it is the bioculture that act as  game changers in phosphate reduction.???? Want to know how to integrate biocultures in your treatment process? Contact Us to learn more.

Let’s explore the effectiveness and correct mechanism of phosphate removal using biocultures:

1.What are Phosphates?

Phosphates (PO₄³⁻)  are chemical compounds that contain phosphorus.  In industry, mostly chemical intermediates and food processing units have a high amount of phosphates.

2.Why is it a problem for ETP/STP?

  • Poor effluent quality: NGT and most pollution control boards are very stringent in the phosphate levels in the final outlet. If the criteria are not met, it may lead to a bad ESG report and even shutdowns.
  • Eutrophication: Phosphates promote excessive algal deposition and plant growth, leading to depletion of oxygen in receiving water bodies.
  • Effect on biological treatment: High phosphate content may disturb the biological/microbial population. It leads to even growth of filamentous bacteria, leading to sludge bulking, poor biomass settling, and compromising the efficiency of BOD/COD removal.
  • Increased Chemical Dosing costs: High phosphate = higher chemical use → higher sludge production → more dewatering and disposal costs.
  • Risk of Struvite Scaling:  in systems with high phosphate and ammonia, struvite (MgNH₄PO₄) may precipitate, causing scaling in pipes, pumps, and digestors, increasing OPEX and CAPEX.
3. Enhanced biological phosphorus removal (EBPR)

Enhanced biological phosphorus removal (EBPR) processes are designed to culture communities of microorganisms in MLSS that have the Phosphorus Treatment and Removal Technologies. It involves use of specific microbial strains and put in ETP as biocultures. The strains absorb phosphate and are PAOs (polyphosphate-accumulating organisms). These are likely to comprise a variety of bacterial subpopulations, including Acinetobacter, Rhodocyclus, and some morphologically identified coccus-shaped bacteria.

An ideal EBPR process starts with:

  • Anaerobic Zone: The PAOs are first subjected to an Anaerobic environment where Biodegradable COD is fermented into VFA (Volatile Fatty Acids), particularly acetate and propionate, which serve as food for PAOs. PAOs thus metabolize polyphosphate reserve and release phosphorus.
  • Aerobic Zone: In the Aerobic zone, the PAOs take up the released phosphates by multiplying and oxidizing carbon reserves built in the anaerobic phase. Here, WAS (Waste Activated Sludge ) and RAS (Return Activated Sludge) play a very important role.
Critical factors for the success of EBPR:

  • Influent Characteristics:  a minimum influent BOD:P ratio of 25:1 is necessary in order to provide adequate conditions for PAOs to thrive. Note that this ratio is applicable to the influent of the anaerobic phase of the EBPR process.
  • Integrity of the Anaerobic zone: Establishing and maintaining strict anaerobic conditions in the anaerobic zone is critical for PAOs to be able to consume VFAs and store carbon compounds. The presence of oxygen or nitrates will disrupt the process by placing PAOs at a competitive disadvantage with other bacterial populations.
  • Variability: Variability in flows can result in variable anaerobic and aerobic contact times, which can disrupt the process. Flow and load variability can also impact the influent BOD:P ratio. 
  • Dissolved Oxygen: Excessive dissolved oxygen should not travel back to the anaerobic zone hence, DO should be maintained between 0.5 to 1.0 mg/l at the end of the aeration zone.
Conclusion: 

Phosphate removal is different from conventional ETP operations. It requires the right microbes, technical know-how, and physical and chemical treatments. And when physical and chemical treatments are combined with biocultures, can enhance phosphate removal by up to 90%, and also improve microbial population management in wastewater.Ready to revolutionize your wastewater treatment system with biocultures?

No matter how many SOPs or books we read, the ground reality is different, each ETP is different, each industrial effluent is different and one of the most overlooked challenges across these systems is the malnutrition of ETP, where the biological treatment process suffers due to imbalanced or inadequate nutrient supply.

In the world of industrial wastewater treatment, biological systems are the backbone of sustainable and cost-effective operations. But even the best industrial application of microorganisms can’t function without the right nutrients. And for the right nutrients, the same old C:N:P ratio is followed. And to make up this ratio, unfortunately, the conventional nutrient sources such as UREA-DAP, which are supposed to be used for agriculture, are often used in abundance in common effluent treatment plants (CETPs), which is itself a self-sabotage practice.This leads to a common but critical issue—malnutrition of ETP, where effluent treatment plants suffer from poor nutrient availability or imbalance despite excessive chemical input.

Now, readers must be wondering as to what the ideal solution should be for this, as for every nutrient requirement, we need separate chemicals, like for nitrogen, it’s UREA, for phosphorus, it’s DAP, etc.

Well, Team One Biotech has a solution to this universal problem as well. Introducing T1B SustainX- a natural blend of nutrients in powdered form. A 100% replacement of UREA, DAP, Phosphoric acid, and other conventional nutrients.

Team One Biotech’s T1B SustainX offers a smart, eco-friendly, and efficient alternative. Here’s why it’s time to reconsider your ETP nutrient strategy—and how SustainX provides a smart, eco-friendly, and efficient alternative. Contact Us to know how SustainX can transform your operations.

The problem of using fertilizers in Industries as the nutrient source:

Despite their widespread use, these fertilizers contribute to the malnutrition of ETP, disrupting microbial health and system performance.Industrial effluent is not same as soil where we can put the traditional fertilizers. Using such products may give results, but it has some side effects too such as:

  • Nutrient Spikes & Imbalances: Urea, DAP and other products tend to release ammonia and phosphorous very rapidly causing sudden spike in nutrient availability leading to shock induction in the microbes present.
  • Limited Bioavailability: A significant portion of these nutrients is lost through runoff or chemical interactions, offering poor uptake efficiency.
  • Sludge Bulking & Odors: Excess ammonia from urea or phosphorus from DAP can trigger undesirable side effects like bulking, foaming, and odor removal.
  • Eutrophication Risk: Residual nutrients in treated effluents can pollute water bodies, leading to algal blooms and ecological damage.

The Menace of High TDS in Chemical Intermediates- Halophiles at rescue

Salts are one of the most omnipotent components present on Earth. Their presence and absence are significant in almost every chemical, physical, or biological process. Their concentration either depletes or enhances biological growth, preservation, and destruction. However, in effluent treatment plants, salts always have a destructive effect. High TDS in chemical intermediates is never welcomed by any ETP operator as it comes with operational ineffectiveness, damage to infrastructure, extreme difficulty in handling the effluent, non-compliance and high OPEX/CAPEX. Elevated TDS not only jeopardizes downstream operations, leading to scaling, corrosion, and product contamination, but also complicates effluent management, often forcing plants to deploy energy-intensive physicochemical treatments such as Multi-Effect Evaporators (MEE) and Reverse Osmosis (RO).

Although MEE/RO is effective, but is cost-intensive! so, what might be the alternative?  Well, here is the answer, HALOPHILES! Also known as halophilic bacteria, these salt-loving microbes offer a promising solution. This blog will help readers explore how halophiles in the form of microbial culture can help industries achieve operational excellence and reduce the effects and cost.

The Impacts of High TDS :

High TDS streams in chemical intermediates plants often arise from:

  • Salt‐based reactants and catalysts: e.g., chlorides, sulfates, nitrates
  • Neutralization and pH control: addition of acid/base produces salts
  • Process by-products: dissolved organics, chelating agents, metal complexes
Operational Challenges
Effects of high TDS in chemical intermediates include:
  1. Scaling & Fouling
    • Precipitation of sparingly soluble salts (e.g., CaSO₄, BaSO₄) on heat‐exchange surfaces leads to reduced heat transfer and frequent downtime.
  2. Corrosion
    • Chloride‐rich brines attack stainless steels and other alloys, raising maintenance costs.
  3. Product Quality Risks
    • Carryover of salts compromises the purity of intermediates, requiring additional downstream purification.
Hampers Biological treatment: 
  • Due to high TDS, most of the biological wastewater treatment processes fail to generate effective biomass, hence hampering the efficiency.
Regulatory and Discharge Constraints
  • Effluent quality limits: Most jurisdictions cap TDS in discharge at 2,000–5,000 mg/L.
  • Brine disposal: Concentrated RO or evaporator brines often exceed tolerable disposal limits, leading to high disposal fees or zero-liquid discharge (ZLD) mandates.
  • Membrane/Equipment Damages:  Due to hampered biological wastewater treatment efficiency, most of the COD and dead biomass is carried into RO membranes results into their scaling or fouling in MEE.
Physicochemical Solutions: MEE & RO
Reverse Osmosis (RO)

Principle: Semi-permeable membranes allow water to pass under pressure while retaining salts.

  • Recovery ratio (R):
  • Typical performance: Recovery up to 75–85% for moderate TDS (<10,000 mg/L).
Pros:
  • Modular and relatively compact
  • High salt rejection (>99%)
Cons:
  • Membrane fouling/scaling requiring frequent cleaning
  • High‐pressure energy costs (2–6 kWh/m³)
  • Brine at 15–30% of feed volume
Multi‐Effect Evaporator (MEE)

Principle: A Series of evaporators reuses steam from one stage as the heating medium for the next, concentrating brine.

  • Steam economy: up to 8–10 kg steam/kg water evaporated.
Pros:
  • Handles very high TDS (>100,000 mg/L) and organics
  • Robust to feed variability
Cons:
  • Large footprint and capex
  • High thermal energy demand (often >500 kWh thermal/m³)
  • Generates a highly concentrated sludge

Halophilic Biocultures: A Biological Alternative

What Are Halophiles?
  • Definition: Microorganisms—including bacteria, archaea, and some fungi—that not only tolerate but require high salt concentrations (≥3% w/v NaCl) for optimal growth.
  • Types:
    • Moderate halophiles: 3–15% w/v NaCl
    • Extreme halophiles: 15–30% w/v NaCl
Mechanisms of Pollutant Removal
  1. Organic Degradation
    • Many halophiles express salt-stable enzymes (e.g., dehydrogenases, esterases) that mineralize refractory organics, aiding in biological TDS reduction.
  2. Biosorption of Inorganics
    • Cell walls and extracellular polymeric substances (EPS) bind heavy metals and ammonium ions, reducing dissolved load.
  3. Biomineralization
    • Certain strains precipitate metal sulfides or carbonates, facilitating solids separation.
Case Study: Halomonas spp. in High-Salinity Effluent:
ParameterUntreated EffluentAfter Halophilic TreatmentRemoval Efficiency
TDS (mg/L)45,00028,00038%
COD (mg/L)5,2001,10079%
NH₄⁺-N (mg/L)3104585%

In a pilot study, a consortium dominated by Halomonas elongata achieved near‐complete organic removal and 30–40% TDS reduction within 48 hours, showcasing the potential of TDS reduction using microorganisms.

Integration Strategies:
4.1 Hybrid Biological‐Physicochemical Systems
  1. Pre‐treatment with Halophiles + RO
    • Step 1: Use halophilic bioreactor to ingest organics and bind metals, lowering fouling precursors.
    • Step 2: Send biologically pre-treated stream to RO, extending membrane life and improving recovery.
  2. Post‐MEE Biological Polishing
    • Concentrate via MEE to moderate brine TDS (e.g., 80,000 mg/L → 120,000 mg/L).
    • Dilute and treat with halophiles to remove residual COD and ammonia, enabling partial recycling.
4.2 Reactor Configurations
  • Sequencing Batch Reactors (SBR): Ideal for flexible loading and high-salt adaptation cycles.
  • Membrane Bioreactors (MBR): Combine biomass retention with ultrafiltration, ensuring high mixed liquor suspended solids (MLSS).
  • Fixed-Film Reactors (e.g., Biofilm Carriers): EPS‐rich biofilms on carriers that thrive in saline feed.
Design & Operational Best Practices:
AspectRecommendation
Salinity GradientsGradual acclimation: start at 3% NaCl, ramp to process levels over 2–3 weeks.
pH ControlMaintain 7.5–8.5; extremes impair enzymatic activity.
Nutrient SupplementationC:N:P ratio of ~100:5:1 for robust growth.
Temperature30–37 °C to optimize halophilic metabolism.
Hydraulic Retention Time24–72 hours, depending on target removal efficiencies.
Mixing & OxygenationEnsure DO ≥2 mg/L for aerobic halophiles; N₂ sparging for anaerobic strains.
Economic & Environmental Benefits:
MetricConventional MEE/RO OnlyHybrid with Halophiles
Energy Consumption (kWh/m³)6–10 (electrical) + 500 (thermal)3–5 (electrical) + 300 (thermal)
Membrane Cleaning FrequencyEvery 2–4 weeksEvery 8–12 weeks
Brine Volume for Disposal (%)20–3010–15
Chemical Usage (antiscalants)HighModerate
Carbon Footprint (kg CO₂e/m³)15–208–12

By biologically reducing foulants and salinity, plants can halve brine volumes, extend membrane life, and cut overall energy and chemical costs by up to 30%. Moreover, the biodegraded organics lessen the environmental hazards of any unavoidable discharges, promoting eco-friendly chemical processing.

Conclusion:

High TDS in chemical intermediates has traditionally been corralled by MEE and RO—solutions that are effective but capital- and energy-intensive, and that generate challenging brines. Halophilic biocultures, however, offer a compelling biological route to alleviate TDS and organic loads, enhancing and de-risking conventional treatment trains. By integrating salt-adapted microbes—either as a pretreatment before RO or as a polishing step after evaporation—plants can achieve lower energy footprints, reduced chemical consumption, and more manageable brine streams.

As the industry seeks sustainability and cost-efficiency, harnessing the power of halophiles represents a strategic pivot: one that turns the very menace of high salinity into an opportunity for greener, sharper operations.
