520			_aThis study was conducted to investigate the potential of Pasaleng clay as a photocatalyst for the inactivation of Escherichia coli (E. coli). The study focused mainly on determining the effectiveness of the TiO2-Pasaleng clay catalyst for inactivating E. coli by UV treatment. Raw Pasaleng clay was beneficiated before impregnation process. The physical characterization of the different catalysts was determined by surface morphology using Scanning Electron Microscopy (SEM) which sought the visible differences in terms of the morphology of the material. The chemical characterization was done by using X-ray Fluorescence (XRF) Analysis which determined the elemental and metal-oxides composition for each type of the catalyst used in the treatment process. TiO2 concentration increased from 0.541 to 19.12 value after the impregnation process. The simulated lake water samples were irradiated using two different UV light intensities, 6W and 10W, and varying catalyst type (PC, 8%TiO2-PC, 10% TiO2-PC, and 12% TiO2-PC). The pure Pasaleng clay was found to be the best catalyst with a 99.67% E. coli reduction on the UV treatment.
