Zero Liquid Discharge System

zero liquid discharge water treatment in pune

Zero Liquid Discharge (ZLD) is a treatment process with the goal of removing all the liquid waste from a system. The focus of ZLD is to economically reduce wastewater and produce clean water that is suitable for reuse, thus saving money and being beneficial to the environment. ZLD systems employ advanced wastewater treatment technologies to purify and recycle virtually all of the wastewater produced.

Also ZLD technologies help plants meet discharge and water reuse requirements, enabling businesses to:

  • Meet stringent government discharge regulations
  • Reach higher water recovery (%)
  • Treat and recover valuable products/ salts from waste streams, such as potassium sulphate, caustic soda, sodium sulphate, calcium salts and many more
  • The conventional way to reach ZLD is with thermal technologies such as evaporators (multi stage flash (MSF), multi effect distillation (MED) and mechanical vapor compression (MCV)) and crystallizers and recover their condensate. ZLD plants produce solid waste as a by-product through solid dryers.

Zero liquid discharge (ZLD) is an engineering approach to water treatment where all water is recovered and contaminants are reduced to solid waste.
