Abstract

The technical feasibility and performance of photocatalytic TiO₂ coatings in batch-process solar disinfection (SO-DIS) reactors to improve potability of drinking water in developing countries have been studied. Borosilicate glass and PET plastic SODIS reactors fitted with flexible plastic inserts coated with TiO₂ powder were shown to be 20% and 25% more effective, respectively, than standard SODIS reactors for the inactivation of E. coli K12. Isopropanol at 100 ppm concentration levels was observed to be completely photodegraded after 24 h continuous exposure to 100 mW/cm² simulated sunlight in a similar solar photocatalytic disinfector (SPC-DIS) reactor. The technique for producing the TiO₂-coated plastic inserts is described and demonstrated to be an appropriate and affordable technology for developing countries.
