Vontron RO Membrane ULP31-4040
Vontron Reverse Osmosis Membrane ULP31-4040
ULP series of ultra-low pressure aromatic polyamide compound membrane element newly developed by Vontron Membrane Technology Co., Ltd. can work under ultra low pressure to reach as high permeate flow and rejection same as regular low-pressure membrane element, and is applicable to desalination of surface water and underground water.
ULP31-4040 Membrane Element
ULP series of ultra-low pressure aromatic polyamide compound membrane element newly developed by Vontron Membrane Technology Co., Ltd. can work under ultra low pressure to reach as high permeate flow and rejection same as regular low-pressure membrane element, and is applicable to desalination of surface water and underground water. It operates under approximately two thirds of the operating pressure of regular low-pressure composite membranes, which can decrease the investment costs for such relevant facilities as pumps, pipelines, and containers, etc. and the operating cost for the RO system, thus increasing the economic efficiency.
Applicable to desalination treatment of those water sources with NaCl lower than 2000 ppm, such as surface water, underground water, tap water and municipal water, ULP series membrane elements are mainly applicable to such as pure water, boiler water replenishment, foodstuff processing, and pharmaceutical production.
