ZERO Liquid Discharge (ZLD): ZERO Series: ZERO-XS90
ZERO-XS 90 is a series of nanofiltration separation membrane element. It is a highly selective fouling resistant nanofi ltration membrane product developed for sodium chloride and sodium sulfate of Low energy consumption resource recycling. It is suitable for the selective separation of TDS 35000-70000 ppm high pollution concentrated brine in zero liquid discharge process of chlor-alkali, desulfurization wastewater, remove sodium sulfate from dyeing wastewater.
◎Selectivity Separation of Zero Liquid Discharge Technology.
◎Suitable for chlor-alkali，desulfurization wastewater, Separation of Monovalent and Divalent Salt in Printing and Dyeing Wastewater.
