Abstract
Disclosed are system and method for filtration which can minimize the contamination of the filtering membrane through a pretreatment and perform the pretreatment and the filtration with a filtering membrane in a single filtering unit so that any need for separate and additional space and facility for the pretreatment can be obviated. The system for filtration of the present invention comprises a fine bubble supplier for providing fine bubbles into the feed water. The pretreatment is performed by supplying the feed water to be treated into the filtering unit through a dynamic filtration layer which is formed in the filtering unit as the fine bubbles rise.
