AN INVESTIGATION ON THE REMOVAL OF ANIONIC AND CATIONIC DYES IN WASTEWATER BY USING SONO-PHOTOCATALYTIC OXIDATION PROCESSES

Abstract

Depending on the development of the industry, the problem of clean water caused by wastewater and other environmental problems have emerged. Today, industrialization has increased and environmental pollution has become an important problem. Wastes released into the aquatic medium from various industrial sources disrupt the natural stabilize and adversely affect living things and the ecosystem we live on. Therefore, the removal and treatment of dye wastes in river and lake waters has started to be a important environmental problem. Classical treatment methods are used for the removal of anionic and cationic dye wastes. However, classical wastewater treatment processes are not a good approach in terms of energy efficiency in the removal of dye waste. Sono-photocatalytic process is one of the preferred alternative processes for the removal of anionic and cationic dyes from wastewater. Sono-photocatalytic oxidation process is the simultaneous use of ultrasound waves and ultraviolet radiation with catalyst support as a result of the synergistic effect. The sono-photocatalytic treatment process greatly increases the efficiency of advanced oxidation processes and chemical reaction. The effect of the sono-photocatalytic process is greater than the combined effects of the two processes (sonocatalytic and photocatalytic process).
