This study was to determine the static acute toxicity on Daphnia magna for the Electric cable Factory Wastewater. Activated sludge process was used to treat the wastewater with three different F/M ratios, 0.36, 0.2, 0.1 mg COD/day.mg MLSS. The results of laboratory bioassay with Daphnia magna were as follows. 1)24hr, 48hr-LC$ of the influent were 17.33% and 11.73%. 2)24hr-LC $ of effluents treated with F/M ratio 0.36,0.26 and 0.1mg COD/day.mg MLSS were 26.69% 32.70% and 38.36% respectively, 48-LC$ of these effluents were 14.48% 27.88% and 31.58% respectively. 3)According to various F/M ratios, the ratios of dffluent 48hr-LC$ to filtrated 48hr-LC$ were 1.58, 1.83 and 1.47respectively 4)Activated sludge process effluents treated with activated carbon had little toxicity on Daphnia magna.
