We have developed a novel ozone resistant microfiltration (MF) module using an organic hollow fiber membrane made of polyvinylidenefluoride (PVDF). A new filtration system using this MF module together with ozone dose provided three to four times higher permeate flux compared with the filtration without ozone. The reaction of ozone with organic materials in feed water was necessary to occur on the surface of the membrane to have higher permeate flux.
