SWC6 are the lowest feed pressure membranes offering low energy consumption. They are preferred where the seawater feed temperature is low, which requires high feed pressures. SWC6 membranes provide lower energy consumption and lower treatment costs. SWC6 membranes are available in two different types, LD and MAX.
Low differential LD Technology models are offered to minimize colloidal contamination when used with conventional pretreatment equipment. They offer consistently low supply pressures and the highest time between two consecutive cleanings.
MAX models have an active membrane surface area of 440 ft 2 (40.9 m 2 ). They provide excellent performance with high TDS and boron removal from hot water.
