      During the operation of the purified water equipment, improper operation or other conditions will inevitably cause the equipment to be in poor working condition, malfunction, etc.
    , causing the first-time user to be caught off guard, so how to effectively avoid it? You must read the following precautions for the operation of purified water equipment: 1.
    The hydrolysis of the reverse osmosis membrane of purified water equipment can easily lead to the deterioration of the performance of the reverse osmosis device.
    3-11 range

    Even if the high-pressure pump of the reverse osmosis device of the purified water equipment is interrupted for a very short time, the device may fail

    It is best to set up an independent water supply system for pharmaceutical purified water equipment using tap water as the water source, which can not only ensure the stable operation of the water supply system, but also reduce the instantaneous impact on the water supply pipe network of the whole plant when the RO system starts and stops

    When the RO device directly draws water from the raw water network, high and low pressure protection facilities should be set up, because most of the tap water network pressure fluctuates greatly

    Always pay attention to the pressure difference of the security filter

    The reason for the sharp rise in differential pressure is mainly the leakage of the turbidity of the security filter

    On the contrary, the reason for the sharp drop in pressure difference is the damage of the precision filter element and the loosening of the fastening screws of the security filter element

    When the pressure difference between the inlet and outlet of the reverse osmosis device of the purified water equipment exceeds the standard, it means that the membrane surface has been polluted or the water flow rate is above the design value

    If the pressure difference problem cannot be solved by flow adjustment, the membrane surface should be cleaned

    Prevent the filter material from entering the reverse osmosis device: choose the appropriate filter water outlet device to prevent the filter from leaking sand and activated carbon; choose the appropriate activated carbon to prevent powder removal during use

    Regularly check and replace the filter element of the precision filter in time to prevent the particle pollution of the reverse osmosis membrane caused by the leakage of the filter element due to installation or quality problems

    When the differential pressure at the inlet of the precision filter is greater than 0.
    15mpa, the filter element should be replaced

    Generally, it should be checked once a month, and the filter element should be replaced every 2 to 3 months

    During operation, it is also necessary to check whether there is gas in the precision filter, and the air cannot be brought into the reverse osmosis membrane

    For the precision filter that is in standby or out of service for a long time, the method of adding formaldehyde protection should be adopted to prevent the proliferation of bacteria

       Users must understand the precautions for the operation of purified water equipment.
    Mastering these points can effectively avoid equipment failures and other situations
