Hydranautics SWC4-LD


Individual offer for 10+ pcs. Please use our ask form.

SWC4 are the highest salt rejecting seawater reverse osmosis  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 seawater reverse osmosis  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.
