Abstract
Advanced oxidation processes refer to a set of oxidative water treatments that can be used to treat toxic effluents at the industrial level, hospitals, and wastewater treatment plants. The aim of this study wastewater treatment process of BTEX compounds presented sample; the use ofH2O2 in combination with U.V. resulted in an enhanced extent of COD removal. The combination of several AOPs is an efficient way to increase pollutant removal and reduce costs. AOPs based on the UV/H2O2 system have shown high efficiency in reducing several organic compounds of environmental relevance. The UV/H2O2 process has additional advantages in that there is no sludge production and high rates of chemical oxygen demand (COD) removal by varying the operating parameters such as time, flow rate, P.H., hydrogen peroxide dosages. The COD removal efficiency of BTEX compounds decreased with increasing hydrogen peroxide dosages. When H2O2 concentration was increased, the COD removal efficiency also increased. The optimized condition for the H2O2/UV process was found at H2O2 dose of 0.5ml/L of wastewater, Toluene & Xylene concentrations maximum COD removal 77% achieved. At this same time, BTEX compounds the maximum COD removal 50% achieved when an H2O2 dose of 1ml/L is added within 60 minutes of the treatment time.
