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.

SWC4 are the highest salt rejecting membranes used to treat varying levels of seawater salinities and produce low TDS permeate.  SWC4 is popularly used in the treatment of sea and highly brackish waters.  SWC4 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.
