Zero Liquid Discharge (ZLD)
Zero Liquid Discharge (ZLD) is an advanced wastewater treatment system designed to ensure complete recovery and reuse of water with no liquid waste discharged into the environment. ZLD solutions are ideal for industries facing strict environmental regulations and water scarcity challenges.
Kalpenviro’s ZLD systems are custom-engineered to treat high-strength industrial effluents and recover maximum usable water while minimizing waste generation. Our solutions support sustainable operations, regulatory compliance, and long-term cost optimization.
WE PROVIDE
OUR ZERO LIQUID DESCHARGE TREATMENT PLANTS
Zero Liquid Discharge (ZLD) System is designed to treat industrial wastewater in a way that allows complete recovery and reuse of water with zero liquid waste discharge. Our ZLD solutions ensure maximum water conservation, strict regulatory compliance, and safe disposal or recovery of solids, supporting sustainable and environmentally responsible operations.
RECOVERED WATER STORAGE & REUSE
High-quality treated water recovered from the ZLD system is stored in dedicated tanks for continuous reuse. This water can be reused in cooling towers, boilers, process utilities, and other industrial applications, reducing freshwater dependency.
ADVANCED MEMBRANE & EVAPORATION SYSTEM
Treated effluent undergoes advanced membrane processes such as RO followed by evaporation and crystallization. These technologies ensure maximum water recovery while concentrating dissolved solids for safe handling.
SALT RECOVERY & SOLID WASTE MANAGEMENT
Dissolved salts and solids are converted into dry crystals using crystallizers and sludge dewatering systems. This ensures zero liquid discharge from the facility and safe disposal or reuse of recovered solids as per environmental norms.
ZLD Process Flow
Step-by-step treatment process for complete water recovery and zero liquid discharge management
1
Effluent Collection & Pre-Treatment
Industrial wastewater is collected and treated through screening, equalization, and chemical treatment to remove suspended solids and prepare the effluent for advanced treatment.
2
Membrane Treatment (RO System)
Reverse Osmosis systems recover maximum water by separating dissolved salts and impurities from treated effluent.
3
Evaporation & Crystallization
Reject water from RO is treated using evaporation systems such as MEE and ATFD to recover remaining water and convert salts into solid form.
4
Solid Waste Handling
Recovered salts and solids are safely handled and disposed of or reused as per regulatory guidelines.
Treated Water Reuse
Water recovered through ZLD systems can be reused for cooling towers, boiler feed, process utilities, and other industrial applications. This significantly reduces freshwater consumption and supports sustainable water management practices.
