A textile processing unit faced significant challenges in treating wastewater containing 0.5-1% Polyvinyl Alcohol (PVA), a synthetic polymer widely used in fabric finishing. The PVA contributed to the Chemical Oxygen Demand (COD), making the effluent non-compliant with discharge regulations. Additionally, the high COD levels limited the reuse of water within the plant, leading to increased fresh water consumption and operational costs.
Problem Statement: Challenges in Textile Wastewater
Effluent from textile processing often contains PVA, which is:
- Non-Biodegradable: Difficult to break down through conventional biological processes.
- COD Contributor: Increases COD beyond permissible discharge limits.
- Resource Intensive: Limits water recycling, increasing dependence on freshwater.
Key Parameters:
- PVA Concentration: 0.5–1% in wastewater
- Objective: Treat 50 KLD of wastewater to achieve:
- COD Reduction: Below regulatory limits
- Water Recovery: Suitable for recycling within the textile plant
