Hollow fiber membrane

Low pressure membrane filtration processes are increasingly competing against conventional surface water treatment plants. In comparison with conventional processes, UF technology has many advantages, but it is also important that a kind of membrane is suitably selected and operated. In this paper,

Hydrophilic hollow fiber ultrafiltration membranes produced from a blend of polysulfone/poly(vinyl pyrrolidone) (PVP, K90) were post-treated with a hypochlorite solution. The results showed that the fluxes of all membranes that were treated with hypochlorite were 4.7–5.3 times higher but the rejecti
