Growing Trend toward Reuse and Zero Discharge

Abstract

As water costs increase and supplies dwindle, more and more industries are turning to high‐tech water treatment systems that recycle and reuse water within plant production processes. This article describes how some of these systems include “closed loop” technology known as zero liquid discharge (ZLD) that recycles all inplant water streams and discharges none to the environment. The trend is benefiting companies like USFilter, which reports a wave of new bookings for ZLD and other industrial water reuse systems.
