—Sultanate of Oman is experiencing rapid increase in water demand due industrialization and population growth. Desalination contributes for about 35% of water demand in Oman and almost all desalination plants are based on conventional energy source. Utilization of solar energy in desalination is good option due its abundance availability throughout the year in Sultanate of Oman. In this paper, the effect of titanium dioxide (TiO2
) nano photocatalysis for the pretreatment step of reverse osmosis desalination has been studied. A tubular photo catalytic reactor was operated with TiO2
thin film coating mode as well as in suspension mode in the presence of sun light. The effect of various parameters viz., Total Organic Carbon (TOC), Dissolved Oxygen (DO), Total Dissolved Solids (TDS), pH, and Salinity were studied.
