The removal properties of dimethylformamide were examined with filtration bio-reactor equipped with filter media. The formation of sludge cake layers to get enough good quality of the effluent by filtration was obtained within 2 minutes after aeration cleaning, where the filtrate showed over 80 NTU at the initial period and below 10 NTU at the stable filtration period. The filtration time over 2,500 ㎎/L of DMF concentration was shown more than 80 minutes, but it showed less than 60 minutes below 1,000 ㎎/L of DMF concentration. The removal efficiency of TOC was over 90% when the concentration of the influent was increased. SS and Colority of the filtrate were shown the similar removal pattern with the filtration time. Therefore, this system may be expected to the treatment of dimethylformamide wastewater. KCI Citation Count: 0
