Oil is composed of organic compounds with varied molecular structure; in water suppress the respiration of plants and animals, and have toxicity effects on flora and fauna. An important pretreatment step for the water containing oil is coagulation with optimal dose of coagulant such as polyaluminum chloride (PAC). The addition of coagulating aids had reduced the PAC optimal dose for by 25-50%. The UV analysis of the treated/untreated water showed significant preferential adsorption for total petroleum hydrocarbons at
254 nm wavelength (A254) and the correlation of this parameter with conventional control parameters - total organic carbon (TOC) and chemical oxygen demand (COD).
