Supercritical water oxidation (SCWO) is a technology being developed for the ultimate destruction of organic wastes in water. The process involves the reaction of organic and oxygen in an aqueous phase under the conditions that exceed the critical temperature and pressure of water. This paper discussed the physico-chemical properties of supercritical water and SCWO progress and reactors. The applications of SCWO to destruction of hazardous organic substances, wastewater and organic sludge were also reviewed....
