What are the key stages in a ZLD Plant's operation?

A Zero Liquid Discharge (ZLD) Plant treats wastewater to prevent liquid discharge. Initially, the wastewater goes through primary treatment, which removes larger solids and oily substances. This prepares the water for more advanced purification.

Next, sophisticated processes like reverse osmosis and evaporation play a crucial role. Reverse osmosis filters out dissolved impurities, yielding clean water for reuse. Evaporation concentrates the remaining brine, reducing its volume significantly and separating more water.

Finally, crystallization may extract valuable salts from the concentrated brine as solid materials. This multi-stage approach allows ZLD plants to recover near-complete water, meet environmental standards, and minimize water usage and pollution.
