Description : Ultrafiltration Membranes
PWT hollow fiber ultrafiltraon (HF UF) membrane elements provide reliable rejection of microorganisms and viruses with low operating costs. PWT hollow fiber membrane elements are offered in standard RO Membrane sizes for use in standard pressure vessels. Our hollow fiber UF elements are ideal for use in small commercial, point-of-use and point-of-entry applications.
One simple step for both clarifying and disinfecting water
A simple procedure called “low pressure” ultrafiltration permits the clarification and disinfection of water in a single step. A membrane barrier acts like a filter for all particles over 10-20 nm in size: pollen, algae, bacteria, viruses, germs and organic molecules.The ultrafiltration procedure is mechanical: it reduces treatment waste and the need to use chemicals, while conserving the mineral equilibrium of the water.
