SWC RO membranes meet the demands of desalination industry.  SWC membranes have improved the productivity and salt rejection for more than two decades while reducing their environmental impact.  SWC membranes come in a range of innovative formulations depending on the level of seawater salinity required.

SWC membranes come in a range of innovative formulations suitable for varying degrees of seawater salinity. Each offers the highest productivity and salt rejection rates in the industry combined with the optimized flow, low fouling and low energy consumption.

This exceptional performance and consistency creates demand for SWC membranes in seawater desalination and high TDS industrial waste water treatment applications, including conventional and hybrid designs.

SWC5 membranes provide optimum salt rejection and permeate flows. They are chosen when lower permeate TDS and lower feed pressures are needed. SWC5 membranes offer highest energy efficiency at lowest costs and are used in mega desalination plants. SWC5 membranes are available in two different types of variants, LD and MAX

Low differential LD Technology models are offered to minimize colloidal fouling when used with conventional pre-treatment equipment. They offer consistently low feed pressures and highest duration between two successive cleanings.

The MAX models have a 440 ft2 (40.9 m2) active membrane surface area.  They provide excellent performance with high TDS and boron removal from warm waters.
