Treatment of municipal sewage wastewater by tio2 based heterogeneous photocatalysis


Sachin Madhavrao Kanawade

This paper describes the photo catalytic degradation of organic pollutants present in them municipal sewage water by using hydrothermally prepared supported photo catalyst. TiO2 deposited calcium aluminosilicate beads (CASB) supports were prepared by hydrothermal technique under mild preparation conditions. The photo catalytic degradation of organic pollutants in the sewage water was investigated under several experimental parameters such as catalyst load, pH, organic concentration, Irradiation time, aeration, stirring, and light sources. The photo catalytic removal of organics and its degradation efficiency was evaluated by determination of reduction in the chemical oxygen demand (COD) values. The organic pollutant degradation efficiency was over a wide range of pH values, irradiation time and optimum catalyst load. In additional effects like aeration and stirring increase the photodegradation efficiency of organic. Easy recovery and reuse of supported photo catalyst, along with higher degradation efficiency is the major advantages and it reduces the over treatment cost.
