FLUIDIZABLE CARRIER WITH BIOFILM FORMATION-INHIBITING MICROORGANISMS IMMOBILIZED THEREIN AND MEMBRANE WATER TREATMENT APPARATUS USING THE SAME

摘要

PURPOSE: A biofilm formation-inhibiting microorganism immobilized fluidizable carrier in which a biofilm formation-inhibiting microorganism is fixed therein and a membrane water treatment apparatus including the same are provided to increase a membrane cleaning period, to reduce a consumption amount of cleaning chemical and to perform long-term filtration by stably maintaining activation of a biofilm formation-inhabiting microorganism, by reducing contamination of membrane in a molecular biological point of view and by obtaining relaxation of membrane contamination due to physical cleaning. CONSTITUTION: A biofilm formation-inhibiting microorganism immobilized fluidizable carrier in which a biofilm formation-inhibiting microorganism is fixed therein and has mobility by underwater aeration. The fluidizable carrier includes a hydrogel. The fluidizable carrier includes at least one kind selected from the group consisting of alginate, PVA, polyethylene glycol and polyurethane. The fluidizable carrier has a three-dimensional network structure through a chemical bridge bond of the inside. The fluidizable carrier is formed with a spherical shape. The biofilm formation-inhibiting microorganism is a gene recombination microorganism or a natural microorganism capable of generating a biofilm formation-inhibiting enzyme. The biofilm formation-inhibiting microorganism is capable of generating a quorum quenching enzyme. The quorum quenching enzyme is lactonase or acylase.
