Having the properties of low-pressure, high permeated flow and excellent desalination performance, LP membrane series is mainly applicable to brackish water desalination. Furthermore, with the excellent properties in removing soluble salts, TOC and SiO₂, it is particularly applicable to preparation of high-purity water for electronic and electrical power industries.

Working under the conditions of ultra low operating pressure, ULP membrane series can achieve as high permeated flow and rejection rate as regular low-pressure membranes can. It runs under approximately two thirds pressure of that of regular low pressure compound membranes, and can achieve a rejection rate of as high as 98.0%.

     Working under the conditions of extremely low operating pressure, XLP membrane series can achieve as high permeated flow and rejection rate as regular low-pressure membranes can. It runs under approximately half pressure of that of regular low pressure compound membranes, and can achieve a rejection rate of as high as 98.0%.

       Designed for sweater desalination, the SW series can increase the permeated flow by improving the structure of membrane elements, thus decreasing the number of membrane elements installed. It has the properties of high rejection rate, persistent performance, low operation cost and low investment in equipment, and can ensure that drinking water can be produced from seawater simply by one-stage RO treatment.

      FR membrane series is mainly applied to reuse of wastewater and treatment of high-polluted surface water. For treatment of water with inferior quality grade, it adopts the design of wider feedwater inflow conduit net, which makes it easier to be cleaned. Furthermore, the membrane surface has been specially processed with special technology, thus changing the electric charge and the smoothness of membrane surface, increasing the hydrophilicity of membrane surface, reducing the contaminants and microbes adhering to the membrane surface, bringing about the performance of stronger resistant to scaling, organic contamination and microbe contamination, and therefore decreasing the contamination speed of membrane element and elongating its service life.

      HOR (high oxidation resistant) series of aromatic polyamide compound membrane element newly developed by Vontron Technology Co., Ltd. has the properties of low operating pressure, high permeate flow and excellent rejection performance, etc. Besides, the use of special synthetizing process enhances the oxidation property of membrane element and enables the membrane element to endure the impact by certain  magnitude of oxidative substance, thus simplifying and optimizing the pretreatment process of RO system, decreasing the microbic contamination of membrane element, saving the operating cost and elongating the service life.

 The 1812-sized and 2012-sized residential membrane elements are mainly applicable to various small-sized systems, such as household water purifier and other water purifying devices in hospital and laboratory.

 Being suitable for the desalting treatment of those water sources with salt concentration lower than 2000 ppm, such as surface water, underground water, tap water and municipal water, etc., ULP series are mainly applicable to numerous applications of various sizes, such as pure water, boiler water replenishment, foodstuff processing, and pharmaceutical production, etc.
