Özet

BACKGROUND: Supercritical water oxidation (SCWO) of dyehouse waste-water containing several organic pollutants has been studied. The removal of these organic components with unknown proportions is considered in terms of total organic carbon concentration (TOC), with an initial value of 856.9 mg L(-1). Oxidation reactions were performed using diluted hydrogen peroxide. The reaction conditions ranged between temperatures of 400-600 degrees C and residence times of 8-16 s under 25 MPa of pressure.
