The ultra-low-pressure membrane elements are made from rolled polyamide composite membranes developed and produced in-house. The product has the characteristics of high desalination rate, low operating pressure and large membrane flux. The product can be widely used for the desalination of municipal tap water, groundwater and other raw water, such as community drinking water, food and beverage production water.
