Roadmap towards Zero Liquid Discharge Studies

According to CPCB, “Zero Liquid discharge (ZLD) refers to the installation of facilities and system which will enable industrial effluent for absolute recycling of permeate and converting solute (dissolved organic and inorganic compounds/salts) into residue in the solid form by adopting a method of concentration and thermal evaporation”.

ZLD helps an industry in eliminating the discharge of wastewater into nearby water bodies or on land, by enabling efficient recycling of wastewater streams. The institute has formulated an “Action Plan cum Roadmap towards ZLD” for some of it’s studies for industrial sectors such as Textile and Ferrous & Non-Ferrous.

A three-pronged approach is adopted for developing the roadmap for Zero Liquid Discharge which focusses on segregation of wastewater streams from various manufacturing operations and utilities and customized decentralized wastewater treatment for recycling in plant operations.
