XLP series of extremely low-pressure aromatic polyamide compound membrane elements can work under ultra-low pressure to reach as high permeate flow and salt rejection as regular low-pressure membrane elements can, and is applicable to desalination of surface water and underground water. It operates under approximately half the operating pressure of a regular low-pressure composite membrane and achieves a salt rejection rate of up to 99.0%, 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 sources with low salinity not requiring high salt rejection such as surface water, underground water, tap water, and municipal water, which have a salt concentration lower than 1000 ppm, XLP series of membrane elements is particularly applicable to the second-pass desalination with two-pass RO system, and is mainly applied to numerous applications of various scales, such as pure water production, boiler water replenishment, foodstuff processing, and pharmaceutical production.

SW series of aromatic polyamide compound membrane element developed by Vontron Membrane Technology Co., Ltd. is applicable to desalination of seawater. By optimizing the structure of membrane element, the SW series increases the permeate flow, and requires fewer elements for same permeate flow. It is characterized by low operating pressure, low investment in equipment, excellent rejection rate and reliable performance.
