The core SINOMEMB ® series SNU-HO-2-860 hollow fiber UF membrane element is suitable for systems
with a capacity greater than 50m 3 /hr (220 gpm) . Compared with longer membrane modules, shorter membrane
modules (60 inches) provide higher separation efficiency and can adapt to a wider range of influent water quality ,
