ULP series of ultra-low pressure aromatic polyamide compound membrane element
newly developed by Vontron Technology Co., Ltd. can work under ultra low pressure
to reach as high permeate flow and salt rejection as regular low-pressure
membrane element can, and is applicable to desalination of surface water and
underground water. It operates under approximately 2 thirds of the operating
pressure of regular low-pressure composite membrane, and achieves
a salt rejection rate up to 98%, 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.
ULP series/ Vontron ULP21 2521 Series membrane element
Vontron ULP21 2521 series of membrane element desalination for surface water and groundwater, tap water and municipal water water treatment on salinity below about 2000ppm, mainly used in various fields of all sizes of pure water, boiler water supply, food processing and pharmaceutical manufacturing industry etc..

ULP series membrane element
1, product introduction ULP (Ultra Low Pressure) series is used for ultra low aromatic polyamide composite membrane element of surface water and groundwater desalination era Walton company newest development, can operate in low pressure conditions to reach the same high and conventional low-pressure membrane water flux and desalination rate. The operating pressure is about 2/3 of the operating pressure of the conventional low pressure composite film, and the desalination rate is up to 99.5%. So as to reduce the investment cost of the pump, pipeline and container and the operation cost of the reverse osmosis system, and improve the economic benefit.
Vontron ULP21 2521 series of membrane element desalination for surface water and groundwater, tap water and municipal water water treatment on salinity below about 2000ppm, mainly used in various fields of all sizes of pure water, boiler water supply, food processing and pharmaceutical manufacturing.
