Nanofiltration Process for Enhanced Treatment of RO Brine Discharge

Membranes, 2021
Brine discharge of reverse osmosis (RO) desalination plants represents a challenge for both inland and coastal desalination plants. Zero-liquid discharge (ZLD) can be accomplished by using additional stages of RO, which can recycle that brine water, but ...
