SWC (Seawater Composite) membranes offer a consistently pure end-product with lowest energy consumption
at varying levels of seawater salinities. SWC membranes are available in 4” and 8” diameters.

LD represents a patented 34 mil thickness feed
spacer that represents low differential pressure
(ΔP), prevents colloidal fouling and increases
effectiveness of membrane cleaning.

MAX represents the technology of maximized
membrane area of 440 ft2 to reduce the number
of elements, thereby saving the cost.


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

SWC5
• Provide optimum salt rejection and permeate flows.
• Offer highest energy efficiency at lowest costs and are used in
mega desalination plants.

SWC6
• Lowest feed pressure membranes offering low energy
consumption.
• Preferred when the seawater feed temperature is lower which
requires high feed pressures.
• Result in low energy consumption and lower treatment costs.
Available in “LD” for optimized fouling resistance
Available in “MAX” for highest membrane active area
