Title:
REVERSE OSMOSIS MEMBRANE FILTER FOR PREVENTING FORMATION OF BIOFILM, METHOD FOR MANUFACTURING SAME AND WATER TREATMENT APPARATUS USING SAME
Document Type and Number:
WIPO Patent Application WO/2015/182850
Kind Code:
A1
Abstract:
The present invention relates to a reverse osmosis membrane filter for preventing the formation of a biofilm, which treats the supply water of a water treatment apparatus, a method for manufacturing the same and a water treatment apparatus using the same, and the membrane filter comprises: a first spacer having a microbial substance impregnated therein; a reverse osmotic membrane for treating supply water flowing into the first spacer; and a second spacer discharging permeate water treated in the reverse osmotic membrane and into which a microbial substance is impregnated. Therefore, the present invention impregnates microbial substances in the first spacer and the second spacer of the reverse osmosis membrane filter treating supply water of the water treatment apparatus so as to prevent the formation of a biofilm in advance, thereby providing an effect of preventing the deterioration of flux and processing efficiency according to membrane contamination in a membrane filtration process and simultaneously reducing operating expenses through the extension of a membrane replacement cycle.
