|Abstract||This study aimed at evaluating the effect of aluminium sulphate (Alum) and polyaluminum chloride (PAC) coagulation, ozonation, their combination, coagulant dose and bromide on the total organic carbon (TOC) removal, disinfection by-products (DBPs) formation and D. Magna toxicity in different origin waters (from Buyukcekmece and Omerli in Istanbul-Turkey and Carmine in Salerno-Italy). Optimum coagulation dose for TOC removal was found to be 40 mg/l while 80 mg/l was reported for the enhanced coagulation. TOC removal was almost the same at the alum dose range of 40-100 mg/l however enhanced coagulation dose of 80 mg/l exhibited the lowest total trihalomethane formation potential (TTHMFP). It was observed that pre-ozonation before both alum and PAC coagulation processes enhanced the removal of TOC and reduction of THMFP. In contrast, haloacetic acids formation potential (HAAFP) increased after coagulation, ozonation and their combination. As expected, adding of 300 ?g/l bromide increased the brominated disinfection by-products. The treated samples exhibited less or more toxicity on D. magna due to treatment method and origin of raw water.|
