Organic Effluent Water Treatment Plant

An Organic Effluent Water Treatment Plant is a specialized Effluent Treatment Plant (ETP) designed to treat wastewater containing high concentrations of organic pollutants such as BOD, COD, oils, greases, and other biodegradable substances. These plants use a combination of physical, chemical, and biological processes to efficiently reduce organic load and ensure treated water meets environmental standards.

Key Treatment Processes

• Preliminary Treatment: Includes bar screens to remove large solids, grit chambers to settle heavy inorganics, and oil traps to separate oil and grease from the wastewater.

• Equalization Tank: Balances fluctuations in flow and pollutant concentration, stabilizing the influent for uniform treatment.

• Chemical Treatment: Uses coagulants and flocculants (e.g., alum, PAC) in flash mixers for coagulation and flocculation to remove suspended solids.

• Primary Clarification: Settles out flocculated solids as sludge.

• Biological Treatment: Utilizes aerobic processes such as Activated Sludge Process (ASP), Moving Bed Biofilm Reactor (MBBR), Sequential Batch Reactor (SBR), or anaerobic processes like UASB to biodegrade organic pollutants.

• Tertiary Treatment: Includes pressure sand filters and activated carbon filters for polishing before disinfection with UV or chlorination.

• Sludge Management: Involves thickening, dewatering, and disposal or reuse of sludge generated during treatment.

Benefits

• Effectively reduces organic pollutants, ensuring compliance with discharge norms.

• Recovers valuable water for reuse in industrial processes or irrigation.

• Minimizes environmental pollution and health hazards.

• Customizable design based on industry type, effluent characteristics, and volume.

Applications

• Industries like textiles, food processing, pharmaceuticals, chemicals, and distilleries generating organic-laden effluents.

• Municipal wastewater treatment with significant organic waste load.

• Facilities requiring zero liquid discharge (ZLD) or advanced treatment for reuse.

The design and operation of an organic effluent water treatment plant prioritize efficient removal of organic contaminants through integrated physical, chemical, and biological treatment stages, ensuring environmental safety and sustainable water management.
