U-jm-gy is a standard micron core filter specially designed for water treatment field. Different from the general rough filter, u-jm-gy adopts up to 5-7 polishing treatments to ensure that the contact surface of material and liquid reaches 0.6 μ m, which is close to the requirements of sanitary grade. The internal and external full mirror surface polishing makes this filter meet all kinds of harsh requirements。 jingmiguolvq view working principle: The standard core filter is a kind of filter which takes the filter element as the filter medium and uses the pressure function to separate the liquid and solid. The method of liquid-solid separation with filter element belongs to microporous filtration technology, which is mainly applicable to materials with solid particles of 0.5-10 μ m or materials with particles larger than 0.5 μ m but not rigid, easy to deform, or with high viscosity between particles or between particles and filtering medium. The liquid to be filtered is pressed in from the inlet of the filter, filtered into the clarified liquid through the filter layer from the outside to the inside through the filter element, and then discharged through the outlet. Impurities are trapped in the deep layer and surface of the filter element, so as to achieve the purpose of liquid filtration. However, the service time of the filter element should not be too long, because the filter element is easy to grow bacteria.
