Precautions for the installation and use of FRP reverse osmosis membrane housing FRP reverse osmosis membrane housing

When installing the two ends and the sealing plate, pay attention to the protection of the seal. The lubricant should be applied in place, especially at the end of the groove slope of the inner stop ring, to ensure the lubrication of the seal ring 0K. Check the fastening strength of the fastening nut of the support plate. Pay attention to all accessories at both ends, whether there is missing installation, whether there is missing debris in the membrane housing , so as to avoid damaging the filter membrane element and the membrane housing due to high pressure drop. Check whether the thrust ring is at the concentrated water end to prevent damage to the filter membrane element during backwashing.

Check connectors (by binding and clamping) to ensure they are properly installed. After installation and inspection, slowly add water to the membrane component (membrane housing), discharge the air in the membrane component and membrane housing , discharge the material after pressure relief, reciprocating several times to prevent water hammer phenomenon, ensure that the sealing country stretch freely and reset. The pressure in the fresh water pipe shall not exceed 125PSI. Pay attention to whether the water pipe is blocked by foreign matter. FRP reverse osmosis membrane housing can not be used as a load-bearing carrier, can not be used as a load bearing or pressure in the upper part, can not be directly related to the pressure part.

Glass fiber reinforced plastic reverse osmosis membrane housing as an important element in water treatment, in the use of water quality requirements are very strict, because the reverse osmosis membrane aperture is very small, to try to remove suspended matter, microorganisms, colloids and organic matter, otherwise the water quality does not meet the requirements, it is easy to cause reverse osmosis membrane blockage and pollutionThe influencing factors of FRP reverse osmosis membrane housing are: inlet pressure, inlet temperature, inlet PH value, and inlet salt concentration. Increasing inlet pressure can improve water production and desalting rate, but the salt permeability is basically unchanged, increasing inlet pressure can improve the desalting rate. When the inlet pressure exceeds a certain value, the intake rate and desalination rate will no longer increase, because each film has a limit, with the increase of water temperature, the intake rate will increase,PH has little impact on the intake rate, but the greater the impact on the desalination rate, the higher the intake salinity, the greater the concentration difference, through the intake rate, which leads to a decrease in the desalination rate.When replacing the reverse osmosis membrane, do a good job of protection, wear protective glasses and gloves, wear protective clothing, etc., if you accidentally splash the reverse osmosis membrane protective liquid into the eyes, you can rinse slowly with a lot of water at this time, and go to the hospital as soon as possible to take medical measures. At the beginning of use, the glass fiber reinforced plastic reverse osmosis membrane housing will have a small amount of protective liquid, if it is used in drinking water or food must be filtered for a period of time, after inspection to determine the water quality standard requirements before use.FRP reverse osmosis membrane housing is generally stored in the wet state is relatively slippery, reverse osmosis membrane around the glass fiber. When moving or installing, wear gloves and protective shoes to avoid being punctured by exposed fibers. So as not to fall off your hands or feet and cause injury. Soak the newly installed reverse osmosis membrane in low-pressure water for about 1 hour, and then enter the scheduling stage after the membrane element is fully adapted to the water quality and temperature.The newly installed reverse osmosis membrane element has a transition period during the initial installation. The length of this time depends on the storage conditions of the membrane element and the correct start-up procedure. The above is the precautions for the installation and use of the FRP reverse osmosis membrane houdsing.
