Description
The following is a brief introduction to the residential membrane elements from Vontron Technology Co., Ltd. These elements are specifically designed for small-sized systems, such as household water purifiers and other water purifying devices in hospitals and laboratories. The ULP2012-100 membrane element is suitable for desalinization systems and water sources with salt concentration lower than 2000 ppm, such as surface water, underground water, tap water and municipal water. The ULP1812-50, ULP1812-75 and ULP2012-100 membranes have an active membrane area of 3.5, 4.2 and 5.0 ft2 (0.32, 0.38 and 0.46 m2), respectively. The average permeated flow is 100 GPD (0.38 m3/d), the stable rejection rate is 95.0%, and the minimum rejection rate is 97.5%.
VONTRONResidential Membrane ElementsBrief IntroductionThe 1812-sized residential membrane elements are mainly applicable to various small-sized systems, such as household water purifiers and other water purifying devices in hospitals and laboratories.Being suitable for desalinization systems and 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.

Important Information1. Any specific application must be limited within the extreme operating conditions. We strongly recommend you to refer to the latest edition of technology manual and design guide prepared by Vontron Technology Co., Ltd., or consult experts proficient in membrane technology. In case the customer fails to follow the operating conditions as specified in this manual, Vontron technology Co., Ltd. will assume no liability for all results.2. The permeate flow listed in the table is the average value. The permeate flow of single membrane element is within a tolerance not exceeding 20% of the nominal value.3.All wet-type membrane elements have been strictly tested before leaving the factory, and have been treated with the solution of 1.0% sodium hydrogen sulfite (an antifreeze solution of 10% propanediol required in winter) for storage purpose, then sealed with plastic bag in vacuum, and further packed in carton boxes. In order to prevent the breeding of microbes during short-time storage, transportation and system standby, we recommend you to soak the membrane elements with protective solution (prepared with RO filtered water) containing 1.0% sodium hydrogen sulfite (foodstuff-purpose).4.Discard the RO-filtered water produced during the first one hour after system start-up.5. During storage time and run time, it is strictly prohibited to dose any chemical medicament that may be harmful
