1, strict control of the quality of water intake, to ensure that does not meet the indicators of the water shall not enter the water purification equipment, otherwise it is very easy to cause fouling of the membrane element of the water purification equipment blockage, a serious impact on the effluent water quality.
2, reverse osmosis water purification equipment water inlet by RO inlet valve control, if the water inlet does not change the inlet valve, do not mess with the full open or fully closed. RO thick row of regulating valves are used to adjust the recovery rate of the system, such as the recovery rate does not change, do not mess with the thick row of regulating valves, absolutely prohibit the full open or fully closed.
3, water purification equipment is not easy to long shutdown, such as the preparation of more than 72 hours of shutdown, the application of chemical cleaning device to the components filled with 1% hydrogen sulfate and 18% glycerin implementation of protection.
4, feed water temperature control, should be based on the actual water consumption, take the critical pressure (inlet pressure below the value of the desalination rate to produce a significant drop in the pressure value) can not meet the requirements of the water and water quality of the lowest temperature as the temperature of the feed water for the period of time, so as to reduce the attenuation of the membrane water.
5, when the reverse osmosis water purification equipment occurs high and low pressure alarm, first check the security filter to the high-pressure pump between the manual valve opening is too small, and then check the RO inlet regulating valve and the thick drain valve is normal, and then press the high and low pressure alarm reset button to restart the pure water production equipment.
6, reverse osmosis water purification equipment after each shutdown should be started to let the device in the water inlet pressure of 0.4Mpa under the condition of flushing for 10 minutes.
7, operating pressure control, should meet the water production and water quality under the premise of taking the lowest possible pressure value, which is conducive to reducing the membrane of the water flux attenuation, reduce the replacement rate of the membrane.
8, the operator should be in every hour on the operating parameters for recording, testing the use of water purification equipment and water quality. The main records should include: water: PH value, conductivity, pressure, SDI, water temperature. Produced water: conductivity, flow rate, PH value, concentrated water: flow rate, pressure and water pressure of each section.
