Low Pressure Membranes Ulp Series; ULP series ultra low pressure aromatic polyamide compound membrane elements can operate under ultra low pressure to achieve a high permeate flow and salt rejection as normal low pressure membrane elements. It can be applied to the desalination of surface water and groundwater.
They operate at about two-thirds of the operating pressure of normal low pressure composite membranes. They can achieve a salt rejection rate of up to 99.5%. This can reduce the investment costs of related components such as pumps, pipes and vessels. Including the operating cost for the RO system, thus increasing the economic efficiency.
