Treatment of textile Industry Waste water using Solar photo Catalysis

摘要

The present study investigated the application of solar photo catalysis in the treatment of textile industry wastewater using zinc oxide (ZnO_(2)) and Titanium dioxide (TiO) as photo catalysts. Thin films of nanometer precision were prepared by coating chitosan and catalyst inside the glass tubes by Layer-by-layer (L-b-L) technique. A recirculation reactor set up was fabricated using the coated glass tubes and the experimental studies were carried out under solar irradiation. The experimental results indicated an appreciable decrease in Total Organic Carbon (TOC), Chemical Oxygen Demand (COD) and turbidity within two hours of exposure under solar radiation.
