1. Contaminations of ground water systems by organic chemicals pose a serious environmental threat. Advanced Oxidation Process is the important field in the environmental chemistry science. In this among, the tremendous amount of research that has been carried out in the two closely related fields of semiconductor photo electrochemistry and photocatalysis during the past three decades continues to provide fundamental insights and practical applications. This led to the development of new materials, improved production processes, advanced properties, and an increase in the number of applications spanning many industrial sectors. The photocatalytic oxidation of organic compounds in water has received the most attention. In this project, we made new photoreactor for photocatalitic applications in degradation of any organic and other pollutants in urban wastewater. This reactor has been worked by three important process that consist of ultrasonic, ozonation and nanophotocatalyst. At first, we synthesized novel type of nanostructured materials that possess best photocatalytic performance under visible, solar and UV light. After that, we design ultrasonic pizo under main section of rector. the ozone gas injected by a diffuser from external source. The synergitic effect of ozonatation, ultrasonic waves and nanophotocatalyst reactions led to treatment of wastewater at high efficiency. This nanoreactor can be removal surfactant, dyes and other toxic organic waste. Also, it can be sufficiently decrease COD, BOD and TOC from natural industrial and domestic wastewaters. This photoreactor contain of several section for achieving maximum efficiency in water and wastewater treatment. New Nanosystem Mixed Reactor for Urban Wastewater Treatment
