Vontron Reverse Osmosis Membrane ULP21-4040

Vontron Reverse Osmosis Membrane ULP21-4040

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.

4" LP Series Of Low Pressure RO Element

The LP (low pressure) series of aromatic polyamide compound membrane elements developed by Vontron Technology Co., Ltd. has the properties of low-pressure operation, high permeate flow, and excellent desalination and is applicable to the desalination of brackish water. Besides, it is particularly applicable to the fabrication of high-purity water for the electronic industry and electric power industry owing to its excellent performance in removing soluble salts, TOC, SiO₂, etc. Being suitable for desalting such water sources as surface water, underground water, tap water, and municipal water, etc., the LP series is mainly applicable to the treatment of various industrial water such as industrial-purpose pure water, boiler water replenishment in power plants, and can be also applied to such brackish water applications, such as treatment of high-concentration saline wastewater and production of beverage-purpose water.

LP series of the low-pressure elements is normally suitable for the treatment of brackish water, surface water, underground water, and municipality water with TDS that is less than 10000ppm. It is mainly used for producing various scales of bottle water, drinking water, industrial used pure water, high purity water, boiler replenishment water, also for wastewater reuse, material concentration, purification, and refining purposes.
