ULP series/ Vontron ULP21 2521 Series membrane element
1, product introduction
ULP (Ultra Low Pressure) series/ Vontron ULP21 2521 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 industry etc..
2, important information
For the recommended design scope, please refer to the latest version of the Beijing times Walton Technology Co., Ltd., technical manuals, design guidelines, or consult the membrane technology experts. If the user does not strictly follow the operating conditions provided by the sample, Beijing times Walton Technology Co., Ltd. will not bear all the consequences arising therefrom.
The water quantity listed in the table is the average, and the error of water yield of single membrane element is within 15%.
Wet membrane components are rigorously tested before leaving the factory, and use the 1% Sodium Bisulfite (propylene glycol antifreeze also add 10% when winter) solution for storage processing, and vacuum packaging, packaging for cardboard boxes. In order to prevent microbial growth during storage, transportation, and standby systems in the short term, it is recommended to use a protective solution containing 1% Sodium Bisulfite (food grade) (RO).
The first hour of operation of the RO water to discharge.
In the storage and operation of the prohibition of the addition of any influence on the membrane components of chemical agents, such as the use of such chemicals in violation of the Beijing times Walton Technology Co., Ltd. will not bear all the consequences arising therefrom.
