Important Information
1.         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).

Brief Introduction
 
ULP series of ultra-low pressure aromatic polyamide compound membrane element newly developed by Vontron Technology Co. Ltd.
 
Membrane can operate 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 membranes, and achieves a salt rejection rate of up to 99.5%, which can decrease the investment costs for relevant facilities such as pumps, piping and the operating cost for the RO system, thus increasing the economic efficiency.
 
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 membrane elements are mainly applicable to numerous applications of various scales, such as pure water, boiler water replenishment, foodstuff processing, and pharmaceutical production, etc.
