Zero Liquid Discharge is a process that is beneficial to industrial and municipal organizations as well as the environment because it saves money and no effluent, or discharge, is left over. ZLD systems employ the most advanced wastewater treatment technologies to purify and recycle virtually all of the wastewater produced. Also, Zero liquid discharge technologies help plants meet discharge and water reuse requirements, enabling businesses to:

• Meet stringent cooling tower blow down and flue gas desulfurization (FGD) discharge regulations.
• Treat and recover valuable products from waste streams.
• Better manage produced water.

A Zero liquid discharge facility (ZLD), is an industrial plant without discharge of wastewaters. Target ZLD is normally reached by Wastewater strong recovery ‘clarification needed Separation by evaporation or boiling of water part of wastewater not reusable, in evaporators, crystallizers and condensate recovery. ZLD plants produce solid waste.
