BIOFILM SUPPORTED REVERSE OSMOSIS MEMBRANE FILTER AND METHOD FOR PREPARING THEREOF AND METHOD FOR TREATING WATER USING THE SAME

摘要

The present invention relates to a reverse osmosis membrane filter for inhibiting biofilm formation, a method for preparing the same, and a water treatment apparatus using the same. The reverse osmosis membrane filter for inhibiting biofilm formation, which treats supply water of the water treatment apparatus, comprises: a first spacer in which supply water flows in from one side, concentrated water is discharged to the other side, and antimicrobial substances are impregnated; reverse osmotic membranes which are individually installed around the outer and inner circumferences of the first spacer, and treat the supply water supplied into the first spacer; and second spacers which are installed around the outer circumferences of the reverse osmotic membranes, and discharge the permeated water treated in the reverse osmotic membranes, and in which antimicrobial substances are impregnated. Accordingly, the present invention inhibits biofilm formation in advance by impregnating the antimicrobial substances into the first and second spacers of the reverse osmosis membrane filter which treats supply water of the water treatment apparatus, thereby preventing flux caused by membrane contamination and degradation of process efficiency during a membrane filtration process, and saving operating costs through extension of a membrane replacement period.
