| Abstract | ||||
| Conventional coagulation is a difficult process that may have a negative effect on the environment because of the complexity of the harmful substances in industrial wastewater and the nature of the leftover sediment. The goal of the current study is to better understand how to treat turbid and oily industrial wastewater by using combinations of kaolin and aluminum sulphate (alum, the most popular coagulant). Experiments were conducted on oil effluent samples from a refinery plant in Egypt using the standard Jar test at room temperature with a range of pH values and a hybrid coagulant dose. The samples of feed wastewater and treated water were evaluated for turbidity and oil content. The outcomes demonstrate how well an alum/kaolin hybrid coagulant works to reduce the turbidity and oil content of oily wastewater. As a hybrid coagulant, the addition of 19.5 mg/L alum and 0.7 g/L kaolin successfully reduced the treated wastewater's turbidity from 230 to 1 NTU with a turbidity removal efficiency of 99.57% . the treated water sample oil content was reduced from 820 to 2 ppm with a removal efficiency of 99.77%. | ||||
