Zero Liquid Discharge Plant

Product Details:

Zero liquid discharge (ZLD) refers to a treatment process in which the plant discharges no liquid effluent into surface waters, in effect completely eliminating the environmental pollution associated with treatment.

Zero Liquid Discharge (ZLD) is a 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.

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 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.

A ZLD treatment system utilizes advanced technological water treatment processes to limit liquid waste at the end of your industrial process to, as the name suggests, zero.

An efficient and well-designed ZLD treatment system should be able to:

• handle variations in waste contamination and flow

• allow for required chemical volumes adjustments

• recover around 95% of your liquid waste for reuse

• treat and retrieve valuable byproducts from your waste (i.e. salts and brines)

• produce a dry, solid cake for disposal
