    In the whole process of osmosis membrane filter pretreatment of water supply, stainless steel membrane shell has a certain guarantee effect on membrane separation technology, so that the pure water produced by RO reverse osmosis processing technology has made great progress. The barrel body and the top tank of stainless steel membrane shell have passed the strict pavement design scheme, which improves the calculation focus, ensures the structural safety, and ensures the safety and stability of the water purification system under the pretreatment working pressure.

    stainless steel membrane shell

    Stainless steel membrane shell can be divided into two types: seam and no seam, and is made of stainless steel plate. The bearing end cover material is ABS and stainless steel plate, the silicone material O-ring has high sealing performance, high sealing performance, long service life, and the inlet and outlet water has end entry and side entry. The membrane shell is divided into card sleeve type, flange type and built-in type. The shell is made of 304 seamless stainless steel tube, which has good sealing performance, high pressure resistance, not easy to age, and is convenient to install and clean the membrane.

    The advantages and disadvantages of stainless steel membrane shell in feedwater pretreatment can directly affect the service life of ro membrane element . Whether the water supply is surface water or surface water, there will be some organic chemicals and organic pollutants. If such pollutants are not pretreated and immediately enter osmosis membrane filter for treatment, these pollutants and suspended solids will remain on the membrane surface, causing blockage of flow channels, increasing the working pressure of ro membrane element, reducing water production rate and removing water. salinity, and even cause membrane fouling or membrane damage.
    At the same time, when the concentration of substances and suspended solids in the feed water is very high, the thickness of the feed water screen will pollute the membrane.

    Stainless steel membrane shell plays the role of pressure resistance and safety protection in all system software.
