Abstract:
In this research TiO2 nanoparticles have been used for drinking water treatment. Two samples of contaminated water with E.coli have been used for this work. One sample has been treated with TiO2 nano powder and at the same time exposed to UV from sunlight. The other one has only been exposed to solar radiation.
The results have shown that the disinfection becomes much faster when solar radiation is enhanced with TiO2. The bacteria colonies vanished completely within 5 hours when both TiO2 and UV radiation were used compared to more than 6 hours when only UV radiation was used.
