Sodium chloride recovery from brines for reuse purposes in zero liquid discharge

In the application of the Zero Liquid Discharge (ZLD) strategy, not a single drop of water leaves the waste water treatment plant (WWTP). In the recovery strategy of an actual full-scale ZLD WWTP, the focus lies on high quality water, which is fully recovered from reverse osmosis brine (RO-brine). A residual solid stream is generated and...
