其他摘要：Water source pollution is increasing in recent years and use of new methods of contaminants removal is required. Nanotechnology is a suitable technique for environmental applications. Titanium dioxide is one of most commonly used nanoparticles containing interesting properties for water and wastewater treatment. Purpose of this study was determination of nanoparticles efficiency for removing of heterotrophic bacteria.Spread plate method was used for enumeration of heterotrophic bacteria. Variables of pH, nanoparticle concentration, and contact time were investigated to remove heterotrophic bacteria. pH 7, contact time 90 minutes and heterotrophic population 305 were optimum condition for maximum removal efficiency. Investigation showed also suitability of titanium dioxide nanoparticles for real water samples. It showed that TiO2 nanoparticles have good antibacterial features, so that they were able to remove heterotrophic bacteria. .
