ULP(Ultra Low Pressure) series are the ultra low-pressure aromatic composite membrane elements developed by Vontron Enviro-Tech Co.,Ltd. applicalbe to surface water and underground water. It can work under ultra low pressure to reach as high permeate flow and salt rejection as regular low-pressure membrane element can. It operates under approximately 2 thirds of the operation pressure of regular 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 the operating cost for the RO system, thus increasing the economic efficiency.

 

  Being suitable for the desalination treatment of those water resources with salt concentration lower than 2000ppm, such as surface water, underground water and muncipal water, etc., ULP series membrane elements are mainly applicable to numerous applications of various scales, such as pure water,boiler water replenishment, foodstuff processing, and pharmaceutical production, etc.
