The membrane shell in water purification industry can be divided into food grade PP plastics, ceramics and stainless steel membrane shell. Because the ceramic membrane shell is fragile, the rate of using stainless steel membrane shell is relatively small. These membrane shells are made of food grade PP filter material, ceramics and stainless steel material by high temperature dissolution combination. In the production process of carbon steel filter, the membrane shell is made of food grade PP filter material, ceramic material and stainless steel material. After a very tedious division of labor, finishing, fitting, assembly process, to ensure that the production of the module shell in the size, weight, and film and module shell cover can meet the requirements. In order to ensure quality, some enterprises will set up quality inspection departments, if they do not meet the standards, they will destroy and redo directly. High quality film shell can be checked from material, appearance, size, weight and other aspects of production.

Users can first observe the whole membrane shell, to see whether the appearance of abnormal color, whether there are holes in the chute, whether the fusion at the bottom is perfect and whether the top thread cover is fine, and so on. If all these aspects are up to the standard, it means that the producer has done a better job in the production of membrane shell.
