Ultrafiltration water filter is to assemble membrane components, pumps, pipe fittings and instruments together to form a complete system for water treatment, which is an ultrafiltration device. The design of ultrafiltration device has the same importance as membrane production, and good device design can make the performance of membrane fully play. Ultrafiltration is a new type of membrane technology for water treatment. It has been widely used in the advanced treatment of industrial wastewater and process water, the concentration, purification and separation of macromolecular solutions in the chemical, food and pharmaceutical industries, and the purification of biological solutions. Sterilization, clarification and purification, and preparation of ultrapure water (ultrafiltration water purifiers).

Ultrafiltration is one of the membrane separation technologies driven by pressure. For the purpose of separation of macromolecules and small molecules, the pore size of the membrane is between 20-1000A°. The hollow fiber ultrafilter (membrane) has the advantages of high filling density per unit and small footprint. In the ultrafiltration process, the deep water liquid flows through the membrane surface under pressure, and the deep agent (water) and small molecule solute water-permeable membrane smaller than the membrane pores become purified liquid (filtrate), and the solutes larger than the membrane pores and The solute group is trapped and discharged with the water flow to become a deep shrinkage solution. The ultrafiltration process is dynamic filtration, and the separation is completed in the flow state. The solute is only limitedly deposited on the membrane surface, and the ultrafiltration rate decays to a certain extent and tends to equilibrium, and can be recovered by cleaning.
