The super oxidation, coagulation and flocculation system is applicable to water and wastewater chemical treatment in which oxidation, coagulation and flocculation processes take place in a single vessel.The apparatus and process can be used for treatment of domestic and industrial water and wastewater for removal of organic and inorganic contaminants.The oxidation process can be provided by several oxidizing chemicals such as ozone, hydrogen peroxide, potassium permanganate, chlorine and Ultra Violet Lights, and the coagulation process can be accomplished with several coagulants such as aluminum sulphide, ferric chloride, ferric sulphate.Selection of the chemicals depends on the quality of the water or wastewater to be treated and the treated water quality required, and it covers a wide range of impurities to be removed and specifically difficult to oxidize hydrocarbons and chlorinated organics, and iron, manganese, uranium, arsenic, cyanide, hydrogen sulphide.The apparatus and the process are economical and have a small installation footprint as several processes take place in a single vessel.
