effluent treatment plant

Raj Process Equipments & Systems Pvt. Ltd. is one of the leading Zero Liquid Discharge (ZLD) plant manufacturers in India, delivering turnkey solutions to treat, recycle, and recover industrial wastewater. Our ZLD plants ensure 100% wastewater recovery, enabling industries to comply with environmental regulations while optimizing resources and supporting sustainable operations. What is Zero Liquid Discharge (ZLD)? ZLD is an advanced wastewater treatment process where effluent streams are treated, purified, and reused—ensuring no liquid waste is discharged into the environment. It provides a closed-loop solution, converting wastewater into reusable water and recovering valuable by-products such as salts and chemicals. Industries face increasing pressure from water scarcity, pollution control norms, and sustainability mandates. ZLD systems help meet these challenges while reducing environmental impact. Turnkey ZLD Plant Solutions by Raj Process Raj Process offers custom-engineered ZLD solutions for: Distilleries & Ethanol Plants Sugar Mills Pharmaceuticals & Chemicals Textiles & Dyeing Units Food & Beverage Processing Palm Oil Mills (POME) Power Plants & Refineries Key Process Flow 1.Collection & Flash Mixing → Effluent collected and treated with alum, lime, and polyelectrolytes. 2.Flocculation & Clarification → Suspended solids removed via flocculation tanks and settlers. 3.Evaporation & Concentration → Multiple Effect Evaporators (MEE) concentrate dissolved solids; vapors condensed into reusable water. 4.Crystallization & Drying → Salts crystallized and dried for reuse or safe disposal.
