Chemical Industry Effluent Treatment with T1B Aerobio Bioculture

Introduction:

Effluent treatment is an essential process for the chemical manufacturing industry as it is a significant source of industrial wastewater pollution. Chemical industries produce a wide range of chemicals, and the effluent wastewater from these industries can contain a variety of pollutants that need to be treated before discharge into the environment. Biological wastewater treatment of effluent with bioculture for wastewater treatment is an effective and eco-friendly method for treating industrial effluent from the chemical sector.

A chemical processing industry located at Amaravati MIDC industrial area was perturbed by surging Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD), and Total Dissolved Solids (TDS) levels. Our client had an activated sludge process (ASP) wastewater treatment plant, which had 4 aeration tanks in series. The industrial effluent contained high levels of chemical pollutants such as phenol, formaldehyde, ammonia, and heavy metals like lead, cadmium, and chromium. The industry used microbial culture for effluent treatment to reduce effluent parameters. However, it was incompetent at treating wastewater discharge, which could not meet the Pollution Control Board (PCB) wastewater treatment guidelines.

The initial approach: After a complete study of the effluent treatment plant (ETP) through a questionnaire, an on-site effluent assessment, and discussions with the EHS (Environmental Health & Safety) team, our experts identified numerous challenges to be addressed:

Main Issues:

• High COD levels in wastewater
• High BOD levels in wastewater
• High Total Ammoniacal Nitrogen (TAN) in effluent

Effluent Treatability Study:

Before planning a wastewater treatment scheme, it is crucial to perform an industrial wastewater treatability study to understand the characteristics of industrial effluent and devise an appropriate biological wastewater treatment regime specific to the chemical industry wastewater. Team One Biotech provided the sample for a pilot-scale wastewater treatment trial, which is a laboratory-scale effluent treatment study that confirms the suitability of the bacterial consortium for wastewater treatment present in our product and its development in the effluent stream. These trials were specifically designed to provide a clear indication of whether the microbial solution for wastewater treatment can grow in a given type of effluent without compromising the pollutant reduction efficiency.

Microscopic analysis reports of the sample revealed satisfactory bacterial growth in industrial effluent. Understanding and developing methodologies for the treatment of chemical industry wastewater is necessary due to the scarcity of freshwater resources. The four main constituents in pharmaceutical plant wastewater treatment that regulators are generally concerned with are Total Organic Carbon (TOC), Total Nitrogen (TN), Total Phosphorus (TP), and Total Suspended Solids (TSS).

Treatment Regime Using T1B Aerobio:

T1B Aerobio: A Complete Solution for Industrial Wastewater Treatment

Our team of researchers developed this unique biotech formulation for effluent treatment, T1B Aerobio, which has proven to be extremely beneficial in solving the most challenging industrial wastewater treatment problems over the years. T1B Aerobio is a microbial consortium for wastewater treatment, isolated from nature. The microbes secrete effective biodegrading enzymes, which are completely natural and safe for humans, plants, and animals. These microbes are highly efficient in degrading organic pollutants in wastewater, refractory wastewater contaminants, and toxic industrial effluents even under high TDS levels.

Our team of experts planned to move ahead strategically for maintaining transparency in effluent treatment implementation between us and the industry. Initially, there was a laboratory-scale study, followed by a pilot plant study to build the client’s confidence in our biological wastewater treatment technology. Finally, the treatment was implemented on the actual industrial wastewater treatment plant (WWTP).

Execution:

Plant Optimization:

Team One Biotech recommended some changes in the effluent treatment plant design for the smooth functioning of the biological treatment process.

Initial Dosing Plan:

We planned a 60-day dosing schedule with a higher microbial culture dosing in the first month and a maintenance dose in the second month.

Observation:

We observed that after adding T1B Aerobio, it significantly reduced the COD in industrial wastewater, BOD in chemical effluent, and TAN levels in wastewater. The table below shows the reduction:

Results:

We observed:

• 99% reduction in COD levels
• 99% reduction in BOD levels
• 90% reduction in TAN levels
• Achieved the desired Mixed Liquor Volatile Suspended Solids (MLVSS): Mixed Liquor Suspended Solids (MLSS) ratio of 0.7
• Maintained the required Food to Microorganism (F/M) ratio
• Improved overall effluent treatment plant efficiency

Conclusion:

The use of T1B Aerobio for industrial wastewater treatment in the chemical manufacturing sector proved to be an effective and eco-friendly method. The efficiency of the effluent treatment plant (ETP) improved significantly, stabilizing the biological wastewater treatment process quickly. The treated effluent successfully met the Pollution Control Board (PCB) compliance standards for wastewater discharge norms.
