Zero Liquid Discharge (ZLD) is a water treatment process designed to remove all the liquid waste from a system. The focus of ZLD is to reduce wastewater economically and produce clean water that is suitable for reuse (e.g. irrigation), thereby saving money and being beneficial to the environment. ZLD systems employ advanced wastewater/desalination treatment technologies to purify and recycle virtually all of the wastewater produced. ZLD technologies also help plants meet discharge and water reuse requirements, enabling businesses to:

| - Zero Liquid Discharge (ZLD) is a water treatment process designed to remove all the liquid waste from a system. The focus of ZLD is to reduce wastewater economically and produce clean water that is suitable for reuse (e.g. irrigation), thereby saving money and being beneficial to the environment. ZLD systems employ advanced wastewater/desalination treatment technologies to purify and recycle virtually all of the wastewater produced. ZLD technologies also help plants meet discharge and water reuse requirements, enabling businesses to:
* meet stringent government discharge regulations
* reach higher water recovery (%)
* treat and recover valuable materials from the wastewater streams, such as potassium sulfate, caustic soda, sodium sulfate, lithium and gypsum 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. Thus, ZLD plants produce solid waste. (en)
