Zero discharge means elimination of effluent water through recycling and reuse of industrial waste water. Through this process, salt and other pollutants contained in the waste water are concentrated and crystallized, and then either discharged as solids to be treated in waste treatment plants or be recycled as useful chemical raw materials.
The core of E-VAP Engineering services pvt ltd Zero Liquid Discharge (ZLD) solution for industrial high-salt wastewater treatment is evaporation and concentration. Steam or electrical power is used to drive the evaporation and concentration of high-salt industrial wastewater to recover high-purity fresh water and product salt without liquid.
