After long-term use, a large amount of impurities will accumulate on the surface of the reverse osmosis membrane, which will greatly reduce the flow rate and cause blockage in severe cases. The reverse osmosis membrane needs to be disassembled and cleaned regularly, which not only increases the difficulty of the staff, but also affects the use efficiency of the reverse osmosis membrane. At the same time, the end covers at both ends of the membrane structure are generally threadedly connected to the outside of the membrane structure, so it is more troublesome during installation and disassembly.
