    Ultrafiltration water filter is the use of ultrafiltration technology to purify water mechanical equipment. The difference with other water purification equipment is the use of ultrafiltration membrane filter membrane filters in its mechanical equipment. It is a microporous filter membrane with the same diameter, specification and model, and the rated diameter range of 0.01-0.2μm. Choose ultrafiltration membrane filter filtration method with pressure difference as the driving force.

    1. ultrafiltration membrane filter water treatment steps
    Drinking water is advanced into the membrane tube. Under the action of the pressure difference, many 0.01μm microporous plates covered on the membrane surface only allow water, beneficial minerals and nutrients to pass through and become filtered water. However, harmful substances such as bacteria, rust, colloidal solution, fine sand, suspended solids, and biological macromolecule organic compounds are cut into the ultrafiltration membrane tube and discharged when the ultrafiltration membrane is flushed.
    2.ultrafiltration membrane filter cleaning steps

    After the membrane is used for a period of time, harmful substances such as bacteria, rust, colloidal solutions, suspended solids, biological macromolecular organic compounds and other compounds will adhere to the inner surface of the membrane, which will gradually reduce the water production rate of ultrafiltration water filter, especially in the drinking water environment. When the pollution is serious, it is more likely to cause ultrafiltration membrane filter blockage. Flushing on time can reasonably repair the water production rate of the membrane.

    3.the production of ultrafiltration cartridge
    After the casting process, the entire bundle of ultrafiltration membrane filaments is made into ultrafiltration cartridge as shown in the figure below, which is composed of an ABS shell and an epoxy resin shell on both sides of the shell. The epoxy resin shell is filled with the gap between the membrane filaments and the membrane filaments, resulting in protection between the original liquid and the permeate. The original liquid first enters the pore wall of the ultrafiltration membrane, and after the ultrafiltration membrane is filtered, it becomes a liquid that can penetrate the pore wall of the membrane, preventing the original liquid from directly entering the pore wall of the permeation membrane without being filtered.

    The above is an introduction to the basic knowledge of ultrafiltration membranes for water purification. If you have any other questions, please consult customer service.
