Zero Liquid Discharge

Overview

Zero liquid discharge (ZLD) wastewater treatment is an advanced process designed to eliminate the discharge of any liquid waste from an industrial or municipal facility. The goal of ZLD is to recover as much water as possible from the wastewater stream and minimize environmental impact by treating and reusing the water or converting it into solid waste. The process involves multiple stages of treatment, including physical, chemical, biological processes, concentration, and crystallization to achieve complete water recovery.

Why is Zero Liquid Discharge Important?

In April 2024, the Environmental Protection Agency (EPA) announced that Effluent Limitation Guidelines (ELG) now require coal-fired powerplants to move to a Zero Liquid Discharge (ZLD) strategy for FGD wastewater, Bottom Ash Transport Water, and Combustion Residual Leachate (CRL).
