Title: Regeneration method of alginate-coated membranes to improve membrane contamination cleaning ability
Inventor: SEUNG YEOP KWAK
IPC: C02F1/44
Filed: 2020-07-15
Abstract: An objective of the present invention is to solve a problem that replacement of all membranes is inevitable to recover performance of the membrane when a processing limit of an anti-fouling functional material of the membrane is reached, thereby providing a method for regenerating a water treatment alginate gel-coated membrane having high cleaning efficiency. More specifically, the method comprises the following steps: (S1) introducing a coating layer crosslinked by a secondary bond with a metal ion on the surface of a porous membrane; (S2) removing membrane contaminants on the surface of the membrane together with the coating layer by an external stimulus; and (S3) reintroducing a coating layer crosslinked by a secondary bond with a metal ion on the surface of the porous membrane. Accordingly, the present invention provides a method for regenerating a functional water treatment membrane having a cross-linked coating layer through bonding between alginate and metal ions on the surface of the membrane with high cleaning efficiency. In addition, the functional layer is removed together with contaminants from a membrane, whose performance has been degraded due to fouling, through external stimuli and environmental changes and functional materials are reintroduced to the membrane, thereby restoring permeability of the membrane.
