Abstract: PURPOSE: A method is provided to remove microorganisms that is excessively attached to media pore of a biofilter. According to this method, microorganisms are removed by backwashing with a mixture of backwashing water and air bubbles. Microorganisms are taken away air bubbles from media, and discharged by backwashing water. CONSTITUTION: In backwashing process, backwashing water is mixed with air bubbles having 0.1-2cm of diameter in ratio of 40-90:10-60, and is injected with 5-40m/hr of velocity; also flow rate is controlled as a size of housing.
