The ULP - Industrial Ultra - Low - Pressure RO Membrane Elements developed by Beijing OriginWater Separation Membrane Technology Co., Ltd are aromatic polyamide composite membrane elements, which are used for desalination of surface water and ground water. The elements can achieve higher water permeation under low operational pressure compared with conventional membrane elements, which can greatly save customers system operation expenses and reduce the investments on pumps, pipelines, and vessels to increase the economic benefits. The elements can be applied for the desalination treatment of municipal water resource, tap water, surface and ground water, which has salt content below 2000ppm.
