Ceramic membranes show superior backwash efficiency because they have excellent mechanical strength and high porosity and surface hydrophilicity. Therefore, it is considered appropriate to apply ceramic membranes to treated sewage water containing twice to ten times as much organic matter as general water source.

However, membrane fouling occurs even in ceramic membranes capable of working under extreme operating conditions due to organic. Therefore, this study aimed to control fouling in ceramic membranes by applying ozoneated water to the backwash process in the ceramic membrane process to reuse treated sewage water. This study introduced ozonated water to the backwash process. Ozonated water was produced by injecting a certain amount of ozone into the membrane-treated water produced by the ceramic membrane process in treated sewage water.

This study aimed to control irreversible fouling generating in ceramic membranes through water backwash and ozonated water backwash....
