Designed with increased area and length to yield cost savings on system design and fabrication, the new Ultrafiltration SFP-2880 (photo) is the largest pressurized ultrafiltration module on the market, says the manufacturer. Ideal for a wide variety of treatment applications including industrial wastewaters, the SFP-2880 adds 20 inches of length when compared to the SFP-2860, but still features the high strength PVDF hollow fibers with a nominal pore size of 0.03 microns. This unit allows flexibility in system design by reducing the number of modules, required piping, skid infrastructure, and the size of the compressed air and clean-in-place systems. The 0.03-micron-nominal-pore diameter allows for removal of bacteria, viruses, and particulate matter including colloids to protect downstream processes, such as RO. The polymeric hollow fibers provide high strength and chemical resistance for long membrane life. An outside-in flow configuration offers high tolerance to feed solids that help reduce the need for pretreatment processes. — Dow Water & Process Solutions, Minneapolis, Minn.
