PSW Seires PP String Wound Cartridge Filters are manufactured with honeycomb construction with FDA approved polypropylene wound yarn material, with outer layers loose while inner layers tight. Hongtek uses computer modeling process which optimizes pp string wound cartridges geometrically and maximizes the use of cartridge surface area by the diamond-shaped depth filtration cones.
PP wound cartridges strengthen the density design to provide high flow rate, low pressure drop and excellent dirt holding capacity. PP string wound filters are effective in many industrial processing, such as pre-RO filtration, food & beverage, chemical filter solution, waste water treatment and petrochemical process etc. PP string wound cartridges are economical solutions to reduce fine sediment, including sand, silt, rust and scale particles.
