Application of Solar Nano-photocatalysis in the Pretreatment of Reverse Osmosis Seawater Desalination
Abstract: The reverse osmosis membrane is very sensitive to contaminations present in seawater which makes the pre-treatment step very important to ensure maximum efficiency of the RO process. The photocatalysis can be used to replace the conventional chemical pretreatment process. Semiconductors photocatalysts are used to oxidize contaminated seawater. It can decompose organic matter into smaller compound and low poisonousness inorganic matter thereby increase life span of RO membrane. This research aims …

Characterization and Photocatalytic Treatment of Oil Produced Water Using TiO2
Abstract: Photo catalytic oxidation is gaining momentum in treating waste water very effectively coupled with solar energy. The solar nano photo catalytic technique involves excitation of a semiconductor through the adsorbent of the electromagnetic radioactivity, most generally within the UV spectrum. In one methodology titanium dioxide semiconductor is excited by using photons which possess sufficient electricity to motivate electrons from valence band which known as band gap, to the conduction band. …
