Water is not just a utility — it’s a strategic resource.
At RAJ Process Equipment & Systems Pvt. Ltd., we go beyond wastewater treatment — we engineer complete resource recovery systems that transform waste into value.
Zero Liquid Discharge (ZLD) is a closed-loop approach where:
• Water is recovered and reused
• Effluents are concentrated and converted into solids
• No liquid discharge leaves the plant
Our Core ZLD Technologies
Multiple Effect Evaporator (MEE)
Efficient multi-stage evaporation system delivering high steam economy (up to ~1:6)
Mechanical Vapor Recompression (MVRE)
Next-generation evaporation with minimal external energy
Vapor Integration System
Maximizing energy recovery across the plant
ATFD / Drying Systems
Final step for true ZLD
From Waste to Wealth — Our Approach
We don’t just treat wastewater — we recover value:
• Water for reuse
• Salts & solids for disposal or reuse
• Energy via biogas (for high COD streams like POME)
• Value-added products like fertilizers or animal feed
Specialized ZLD Solutions: POME (Palm Oil Effluent)
Our engineered solutions convert high-organic effluent into:
🔸 Biogas → Energy / CNG
🔸 Concentrated solids → Fertilizer / Animal Feed
🔸 Recovered water → Process reuse
A true circular economy model — turning waste into revenue streams.
