Dow FILMTEC BW30-400FR membrane
Dow FILMTEC? BW30-400FR membrane element adopted dow proprietary fights pollution membrane technology for chemical and physical modification, especially for have a strict pretreatment, but still rich in biological and organic raw water pollutants such as the application area, it showed excellent resistance to pollution ability and can be cleaned characteristics. It is BW30-365FR products FILMTEC dow outspread, BW30-365FR has worldwide the massive customers use showed excellent fight pollution can force and system running economy. BW30-400FR has the following features:
, high effective membrane area (400 ft 2), in not improve operating flux, under the precondition of higher produce a water yield,
The desalination rate, high FILMTEC RO membrane is the world wide range of cleaning pH (pH1 ~ 12) components, able to scale, organic and inorganic microbial real now effectively clean;
, full automatic, accurate manufacturing technology, using to shorten the length, increase the diaphragm membrane leaf number of advanced structure, lower overall pollution levels, maximize the membrane efficiency.
These features user and operators in the treatment of high water polluted by RO when achieve long-term economy and the biggest trouble-free operation.

Dow FILMTEC BW30-365FR fights pollution reverse osmosis element
With reverse osmosis technology been widely accepted, its appli, , , , cation in expanded to many areas, including for high microbial pollution plugging sex of water. In order to improve the reverse osmosis element in high microbial pollution plugging conditions of performance, dow to use the patent technology FT30 film chemical and physical modification, developed FR series fights pollution membrane element. FILMTEC BW30-365FR applies both to drinking water also applies to a non-potable industries. This element also adopted the FilmTec company "shorten diaphragm length, increase membrane leaf number" the unique element structure, not only in produce a water yield but also in can be cleaned sexually, all has the excellence of high efficiency. BW30-365FR effective membrane area with 365 square feet, standard test conditions produce a water yield 36m 3 / d (9500gfd). Use FR components, users can be only less component reaches the design produce a water yield. So that the system is more compact, reduce the system accessories and installation charge. BW30-365FR and BW 30-365 of produce a water yield and desalination rate are the same. Therefore, in the reconstruction, use BW30-365FR replacement BW30-365 components can reduce dirt plugging, drop low system system pressure and prolong the service life of membrane element.
