    The role of reverse osmosis membranes in purified water equipment is very important.
    Therefore, if the performance of reverse osmosis membranes declines, it will inevitably affect the overall water production effect and service life of purified water equipment.
    For this reason, today Xiaobian has sorted out some how to prevent purified water.
    Tips for scaling the reverse osmosis membrane in the equipment for your reference: 1.
    Do a good job in the pretreatment of raw water, pay special attention to the qualified pollution index, and at the same time, sterilize to prevent the growth of microorganisms in the device, pay attention to chloride ions damage to the membrane
    .

    2.
    In the operation of purified water equipment, it is necessary to maintain a suitable operating pressure.
    Generally, increasing the pressure will increase the water production, but if it is too large, the reverse osmosis membrane will be compacted
    .

    3.
    The turbulent flow state on the brine side should be maintained, the concentration polarization of the solution on the surface of the reverse osmosis membrane should be reduced, and the precipitation of some insoluble salts on the membrane surface should be avoided
    .

    4.
    When the purified water equipment is out of operation, dosing and flushing should be performed in the short term, and formaldehyde protection should be added in the long term
    .

       5.
    The water output of the reverse osmosis membrane of the purified water equipment is obviously reduced, indicating that the membrane is fouled or polluted, and chemical cleaning should be carried out
    .

       6.
    Regularly analyze the raw water quality, and adjust the dosage of the antiscalants according to the water quality and the dosage plan provided by the technical support department
    .

       7.
    Strictly prevent the running, running, dripping and leaking of purified water equipment.
    Add the liquid medicine to the reverse osmosis water to truly prevent scaling
    .

       8.
    The flushing method after the outage of purified water equipment is changed to flushing with demineralized water
    .

       Regarding the introduction of how to prevent reverse osmosis membrane scaling during the use of purified water equipment, I believe that you can better manage the operation of the equipment in the future use process to ensure that the equipment can supply standard water sources stably for a long time
