Photocatalytic Ozonation for Treatment of Wastewater

Abstract

Due increase in population worldwide the demand of fresh water increases. So researchers are focused on the wastewater treatment so maximum water can be reused or recycled. From last few years, with the development of new approaches, technologies or designs with the objective to solve new problems or to improve existing systems in this field have increased. The focus of the researcher is now to enhance the efficiency of conventional method and reduce the cost or limitations by merging them and make the methods more economical and environment friendly. One of these development under the advanced oxidation processes (AOP) with application of different technologies. Among them photocatalytic ozonation process forms more hydroxyl radicals.By using the catalyst the decomposition of ozone and hydroxyl radical formation is controlled in photocatalytic ozonation process.This process provide fast degradation and effective mineralization of pollutant present in wastewater.
