Tritech® PNC and SPNC RO membranes have many advantages over the normal polymer membrane in the market. For example, Tritech® PNC and SPNC RO membranes have higher permeate, higher strength, higher flexibility, less stringent requirement for the inlet water, less requirement of the maintenance including backwash, and longer working life span.
