The Nitto Hydranautics SWC5-LD-4040 reverse osmosis membrane is designed for optimum salt rejection and high permeate flows. Suitable for use where lower permeate TDS and lower feed pressures are required. SWC5 membranes offer some of the highest energy efficiencies at low costs.

Low differential (LD) models minimise colloidal fouling when used with conventional pre-treatment equipment. Benefit from consistently low feed pressures and long durations between successive cleanings.
