    Security filter principle security filter, also known as precision filter, is a widely used filter in the water treatment industry, its shell is usually made of stainless steel material, built-in single or multiple filter elements, under the action of pressure, so that the original solution through the filter media, filter residue remains on the tube wall, filtrate through the filter media outflow, so as to achieve the purpose of
    filtration.

    Depending on the filter media, the filter pore size is also different, and the filter pore size is generally in the range of
    0.
    5~120μm.

    There are many kinds of filter elements of the equipment, such as folding filters, wire wound filters, high-flow filters, activated carbon filters, etc
    .

    The filter element of the security filter appears to suck flat reasons The security filter is usually installed before the pressure vessel, which can remove the particles with a turbidity of more than 1 degree, so that the water inlet meets the water intake requirements
    of the equipment behind.

    However, after using almost a certain amount of time, the filter element will appear to suck flat phenomenon, the main reasons for this situation are: 1, the filter element is used for a long time, there is no timely replacement, not cleaned and replaced in time, the resistance of the raw water through the filter element becomes larger, the high-pressure pump in the working process, the vacuum state in the security filter appears, resulting in the filter element suction flat.
    Precision filters are generally replaced at 0.
    1-0.
    15mpa pressure difference in inlet and outlet, and are routinely replaced in 3-4 months
    .

    2, the filter core skeleton support is insufficient, the skeleton support is insufficient, the pressure resistance is poor, the pressure becomes slightly larger, and the filter element is deflated
    .

    3, the filter element is not selected well, the required filtration accuracy is not suitable The selection of filter precision is not appropriate, and not all systems are suitable for filter elements
    with high filtration accuracy.

    In the case of poor water quality, the selected filter element has aperture that is too high or the pressure exceeds its allowable z-high working pressure, which will also cause the filter element to be flattened
    .

    4, the inlet water pressure is not suitable The inlet water pressure is suddenly high and low, which will also lead to the suction flattening
    of the filter element.

    In summary: the phenomenon of squashing of the filter element is caused, which seriously affects the water purification effect
    .

    In the selection of the filter element, it is necessary to comprehensively consider the working conditions of the filter element, select the appropriate filter type and accuracy, and replace it in time to ensure the accuracy of the post-effluent and the service life
    of the post-secondary membrane element.
