Title:
ADSORPTION STRUCTURE, ADSORPTION MODULE, AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2012/056666
Kind Code:
A1
Abstract:
In water treatment plants there is a problem where organic matter dissolved in water adsorbs onto the surface of a reverse osmosis membrane used in high-performance treatment, thus causing membrane performance to deteriorate and necessitating frequent replacement of the reverse osmosis membrane module. In order to solve this problem, an adsorption structure is provided that adsorbs organic matter in treated water, wherein the adsorption structure comprises an outer wall, a plurality of flow paths provided on the inner side of the outer wall, and partition walls for partitioning the plurality of flow paths. The adsorption structure is characterized in that the partition walls are smaller than the diameter of the flow path and have communication holes through which the flow path and other flow paths communicate, and an adsorptive material to which the organic matter adsorbs. As a result, the organic matter in water to be treated can be selectively removed and the replacement frequency of a reverse osmosis membrane can be reduced.
