Abstract

The aim of this study was to assess the conventional coagulation/flocculation treatability efficiency and the toxicity effect of chemically treated effluent on Daphnia magna for fur-suede processing wastewater. Three different conventional coagulants (FeCl3, Al2SO4, FeSO4) were used in this study and the best treatability conditions (coagulant type and dosage) were determined based on COD and Color removal efficiencies. After then, toxicity determination of raw and chemically best treated fur-suede processing wastewater were done using with Daphnia magna standard method. The results indicated that while the highest COD removal efficiency was determined for Al2SO4 as 86 % at 800 mgL-1 and pH=8.5, the lowest efficiency was found as 67 % for the same dosage of FeCl3 . On the other hand, Color removal efficiencies were found as 95-98 % for all coagulants and the best results was observed at Al2SO4 at 800 mgL-1 and pH=8.5. By the way, the best toxicity removal was calculated as 60% for effluents (50% diluted) treated with Al2SO4. These results show that as a first treatment step for fur-suede processing wastewater, chemical coagulation-flocculation with Al2SO4 provide the best performance both to remove COD and Color and also to decrease in toxic effect.
