Textile industry is one of fast growing industries due to rapid increment of citizen numbers. Abundance of industries must be followed with regulation to manage wastewater discharged by industries to water bodies. The inexistence of national regulation concerning wastewater toxicity demands a need to test the toxicity of industrial wastewater discharged to water bodies. This research aims to characterize and identify toxicant(s) present in textile WWTP effluent. Toxicity test was conducted using Daphnia magna as test organism. Toxicant identification is a preparatory study to assess further attempt to reduce toxicity on WWTP effluent. The research was conducted on a textile mills in Cimahi dan batik home industry in Bandung. Acute toxicity test on PT.X WWTP effluent resulted in 24,97% 96-hour LC50 while LC50 of PT. Y treated effluent is 0,362%. Toxicant identification was conducted utilizing Toxicity Identification Evaluation Phase 1. Procedures proven to reduce toxicity in X sample are pH 11 filtration, natrium thiosulfate addition, and EDTA addition. Y sample’s toxicity could be reduced by pH 11 aeration, natrium thiosulfate additon, and EDTA addition . Based on the results, it is concluded that toxicants present in X sample are chlorine and dissolved metals, while in Y sample are oil, grease, and ammonia.
