ZLD – Zero Liquid Discharge

The escalating focus on sustainability has propelled water resource conservation to the forefront of corporate agendas, with “Zero Liquid Discharge” (ZLD) emerging as a pivotal objective. ZLD entails the in-process reuse of all treated wastewater, eliminating its release into the environment.

This goal, increasingly pursued across industries, offers substantial benefits: recycled purified water, reduced disposal costs, raw material recovery, diminished environmental footprint, and regulatory compliance without discharge controls.

The attainment of ZLD hinges on vacuum evaporation technology. Through a blend of technologies like membranes and evaporators, a system capable of producing high-quality purified water for in-process recycling is achieved. Additionally, waste concentrate can yield tangible solid end-products.

Eco-Techno specializes in helping clients, in different sectors, realize ZLD objectives by implementing advanced vacuum evaporation systems tailored to their specific needs.
