Abstract

Zero Liquid Discharge (ZLD) is an ideal situation of complete closed loop cycle, where discharge of any
liquid effluent is eliminated; it is a remarkable effort of every industry who implements it to meet with the environmental
regulation in a challenging way.For achieving ZLD system for the industry, certain steps are needed to be taken. These
steps include: Analysis of major characteristics of all influent streams entering into ETP, Identification of potentially
recyclable streams and highly polluted stream, Segregation of streams on the basis of their characteristics and
applicability of 4R (Reduce, Reuse, Recycle and Recover) principle in particular plant. Optimization of Effluent
Treatment Plant (ETP), RO Plant and Multi Effect Evaporator (MEE) plant. The industry, for which we are working on
ZLD, is basically a chemical industry discharging around 370 m3/day. By achieving ZLD, this huge discharge can be
eliminated and daily water consumption of industry can be reduced significantly
