Photocatalytic disinfection of E. coli using tourmaline-N-doped TiO2 composite

Tzeng J-H, Lin Y.-T., Weng C-H, National Chung Hsing University, TW

Neither the microbicidal mechanism of TiO2 under visible radiations nor their potential effects in the light intensity have yet been well established. In this paper, the photocatalytic inactivation of bacteria was investigated using E. coli, [...]

Method of Liquid Inactivation by Supercritical Ozone

Ma H.C., Yu F.C., Liang C.C., Wang C.F., Kao M.J., Chuang B.N., Industrial Technology Research Institute, TW

Ozone is a tri-atom molecule with powerful oxidizing ability and decay to oxygen with a half-life of approximately 30 minutes. Although the precise mechanisms of ozone disinfection are not firmly established, the effectiveness was already [...]

Disinfection of Cryptosporidium Parvum Oocysts in Water using Ultrasonic Treatment

Olvera M.E., Ilangovan K., Instituto Tecnologico y de Estudios Superiores de Monterrey, MX

Ultrasound in a liquid phase cause mass and heat transfer across the liquid through cavitational processes which act as nanoreactors to generate unstable mechanical equilibrium. The effect of 1 MHz ultrasound on the inactivation of [...]
