The advanced composite membrane material has a dense and uniform structure, which reduces the resistance of water molecules passing through, so that efficient water production can be achieved under low pressure. At the same time, the optimized flow channel design increases the water flow rate on the membrane surface, reduces the deposition of impurities, enhances anti-pollution performance, and ensures stable operation under low energy consumption conditions.
