Implementation of SBR system in a CETP
Implementation of SBR System in a CETP with T1B Aerobio Bioculture
Introduction: 

The SBR system in a CETP situated in Rajasthan handles effluents from over 40 industries in the RIICO sector the system faces difficulty in handling the load of COD above 2000 PPM, owing to discharges from textiles and  chemicals. The SBR system with 4 biological tanks and 4 cycles a day was struggling with its efficiency in terms  of COD reduction, due to which the outlet COD was very high and the load was carried on to the RO, leading to  damage of membranes and high OPEX. Contact us today to learn how we can help optimize your industrial effluent treatment plant (ETP) with customized bioaugmentation solutions.

ETP details: 

The industry had primary treatment, biological treatment, and then a tertiary treatment. 

Flow (current)  2 MLD
Type of process  SBR
No. of aeration tanks  4
Capacity of aeration tanks  3 MLD each
Total cycles in 24 hrs  4
Duration of fill and Aeration cycle  1.5 hrs and 2.5 hrs respectively
Challenges:
Parameters  Avg. Inlet parameters(PPM)  Avg. Outlet parameters(PPM)
COD  3000  800
BOD  1800  280-300
TDS  3000  1200
Operational Challenges: 
  • The primary treatment was working at 5 % efficiency in terms of COD reduction 
  • The whole SBR system was lagging in COD degradation efficiency and sustainability of MLVSS as well. 
  • The Carryover COD and unsettled biomass was traveling to RO, damaging membranes. 
The Approach: 

The agency operating the SBR system in a CETP approached us to solve their current issues.  

We adopted a 3D approach that included : 

  1. Research/Scrutiny :  
  • Our team visited their facility during the winter season as they encountered many issues at that  

         time. Team scrutinized every aspect of the plant to analyze the efficiency of each element. 

  • The visit gave us a complete idea of their processes, current efficiency, trends, and our scope of  

         work.  

  1. Analysis : 
  • We analyzed the previous 6-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. 
Desired Outcomes : 
  1. Reduction of COD/BOD thereby improving the efficiency of biological tanks. 
  2. Degradation of tough-to-degrade effluents and develop robust biomass to withstand shock loads. 
  3. Ensuring proper settling of Biomass to stop carryover to RO, thereby preventing damage to RO membranes.
Execution: 

Our team selected two products : 

T1B aerobio product

T1B Aerobio Bioculture: This product consisted of a blend of microbes as bioculture  

selected as per our analysis to degrade the recalcitrant COD, and ensure sustainability in  

the SBR system.  

Plan of action: 
  1. We devised a 60 days dosing plan, which was further divided into two phases: 
  • Day 1 to day 30 : Loading dose, to develop the population of bacteria and generate biomass.
  • Day 31 to Day 60: Maintenance Dose, to maintain the population of biomass generated. 
  1. Dosing pattern: We advised dosing in all 4 SBR tanks cycle wise viz. during filling and Aeration, to give  the bioculture proper mixing and necessary DO. 
Results: 
Parameters  Inlet parameters  Tank 4 outlet parameters (ppm)
COD  3000 ppm  280-300 ppm
BOD  1800 ppm  60-82 ppm

Before and after adding bioculture

The implementation of the bioaugmentation program resulted in significant improvements in the performance  of biological units in their WWTP: 

  • We were able to achieve around 90 % reduction from their current inlet parameters in COD & BOD,  which was only 70% earlier. 
  • The overall ETP OPEX was reduced by 20%. 
  • The ETP achieved full capacity operations in terms of hydraulic load. 
  • The biological process became more stable and resilient to fluctuations in the influent characteristics. 
  • The RO membrane health was restored and and their damage reduced up to 80%.

Implementation of SBR systems in CETP
Implementation of SBR System in a CETP with T1B Aerobio Bioculture
Introduction:

The Common Effluent Treatment Plant (CETP) situated in Rajasthan handles effluents from over 40 industries in the RIICO sector. Equipped with SBR system in CETP technology, the system faces difficulty in handling the load of Chemical Oxygen Demand (COD) above 2000 PPM, owing to discharges from textiles and chemicals. The SBR wastewater treatment system, with 4 biological tanks and 4 cycles a day, was struggling with its efficiency in terms of COD reduction, resulting in high outlet COD levels. This excess load was carried over to the Reverse Osmosis (RO) system, leading to membrane damage and increased operational expenses (OPEX).
