First, membrane separation technology is a semi-permeable membrane based separation process that can achieve the removal of contaminants in water by selectively preventing the transport of solutes or solvents. เยื่อ separation equipment usually consists of membrane module, pressure device and other auxiliary equipment. The membrane module can select different types of membranes according to different separation processes, such as microfiltration membranes, ultrafiltration membranes, reverse osmosis membranes, etc.
