Raw-Water Pretreatment PP Pleated Filter Cartridge, 0.10-50 µm (CAT#: STEM-BC-2956-ZJF)

This pleated cartridge is designed for raw-water clarification after upstream multimedia treatment. It uses a polypropylene microfiber membrane supported by polypropylene nonwoven layers. The pleated configuration increases filtration area and contaminant-holding capacity. Suspended solids, rust, and other residual particles are retained before downstream treatment equipment. The cartridge is assembled without adhesives and is designed to prevent media shedding. Multiple membrane grades allow selection according to feedwater quality and required retention efficiency. The broad pore-size range supports coarse pretreatment through fine polishing duties. Integrity testing is performed on every completed cartridge.
