Abstract:
PURPOSE: A biofilm formation suppressing microorganism immobilizing column and a separating membrane-based water treating apparatus using the same are provided to suppress the formation of a biofilm on the surface of a separating membrane based on a molecular biological method. CONSTITUTION: A biofilm formation suppressing microorganism immobilizing column includes a hollow fiber membrane. The hollow fiber membrane is the membrane of a column for immobilizing biofilm formation suppressing microorganisms. The microorganisms are prevented from transmitting through the hollow fiber membrane. Water, introducing water components, and signal transferring materials transmit through the hollow fiber membrane to be reached to the inside of the column and a reactor. The microorganisms are trapped and immobilized in the hollow fiber membrane. The microorganisms are gene recombination colon bacillus or natural microorganisms.
