♦ Part one: Frotec RO Membrane Description
1.Brief introduction and Technical Specification
Frotec Membrane ULP (Ultra Low Pressure) series are the ultra low-pressure aromatic composite membrane elements, applicable to desalination of surface water and underground water. It can work under ultra low pressure to reach as high permeate flow and salt rejection as regualr low-pressure composite membrane, and achieves a salt rejection rate of up to 99.5%, which can decrease the investment costs for such relevant facilities as pump, piping, and container etc. and operating cost for the RO system, thus increasing the economic efficiency.
Working under the conditions of ultra low operating pressure, ULP membrane series can achieve as high permeated flow and rejection rate as regular low-pressure membranes can, it rus under approximately two thirds pressure of that regular low pressure compound membranes, and can achieve a rejection rate of as high as 98%.
