Brackish Water RO Membrane Elements and Fouling Resistant RO Membrane Elements are characterized by low-pressure operation, higher water poductivity and excellent desalting performance. The two kind of industrial reverse osmosis membranes are applicable to treat waste water with high TDS and desalination of brackish water.
This product is suitable to treat waste water with TDS from 2000 to 4000 ppm.
High hydrophilic
Long service life
High Rejection rate and stable permeate flow
34mil feed spacers to control fouling
