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.Product specificationsProduct nameProduct NumbersEffective membrane areaft 2 (m 2 )Produce a water yieldgpd (m 3 /d)Stable desalination rateCl - ％BW30 － 365FR174961/174962365 (34)9500 (36)99.5Produce a water yield and desalination rate is based on test conditions: 2000ppm NaCl, 225psi (1.55 MPa), 25oC, pH = 8, 15% recovery.2.
