ZERO Liquid Discharge (ZLD): ZERO Series: ZERO-HP70
ZERO-HP 70 is a series of high pressure reverse osmosis membrane element. The highly desalinized
membrane product is developed for TDS 15000-35000 ppm brine concentration. Based on the SW serial element to improve the performance of the bearing higher pressure, and the Zeta potential and hydrophilicity of the membrane are also improved.
◎Intermediate Concentration and Reduction Stage of Zero Liquid Discharge Technology.
◎Suitable for TDS 15-35 g/L of Feed Water.
