DuPont SFP-2860 Ultrafiltration Membrane 8-inch PVDF RO Pretreatment
The DuPont SFP-2860 is a high-performance PVDF hollow fiber ultrafiltration (UF) membrane designed for demanding water treatment applications. With a 50kDa molecular weight cutoff (MWCO) and 0.03 μm pore size, it effectively removes suspended solids, bacteria (>99.9%), and viruses (LRV≥4), making it ideal for municipal wastewater reuse, RO pretreatment, and industrial process water.

Proper start-up of a UF system is essential for preparing the membranes for operational service and preventing membrane damage. Before commencing system start-up procedures, complete membrane pretreatment, installation of membrane modules, instrument calibration, and other system checks. Refer to the product technical manual for complete instructions.
NOTICE: NSF/ANSI 61 certified drinking water modules require specific conditioning procedures before generating potable water. Drinking water modules may be subject to additional regulatory constraints in certain countries. Verify local regulatory guidelines before usage and sale.
