Performance comparison of commercial TiO: separation and reuse for bacterial photo-inactivation and emerging pollutants photo-degradation.

This research aims to compare the disinfection and degradation effectiveness in water of a commercial suspension of nano-TiO (TiOLevenger) with the standard TiODegussa P25. Photo-inactivation and photo-degradation experiments were conducted with UVA-vis light. Concerning the disinfection, the effects of TiO dose (0-2 g/l), water matrix, bacterium type (Gram-positive or Gram-negative), and bacterial regrowth after the photo-treatments were studied for each catalyst.
