Coating of titanium dioxide crystals on glass are exposed to sunlight in two ways: mobilize and immobilize form. An experiment is conducted in consideration for household application. Coating of titanium dioxide on glass rods (immobilize) and rings (mobilize) are positioned in glass bottles filled with water. Inactivation of Fecal coliform is compared with the normal solar disinfection (SODIS) process. Experiment results shows that titanium dioxide enhances the inactivation efficiency of SODIS by 1:1.3:1.8 corresponding to immobilize and mobilize titanium dioxide, respectively. This development is intended for use by small communities, refugee camps, institutions, and during emergency and disaster situations.
