dc.description.abstractThe Central Arizona Project is a water delivery system which will bring Colorado River water to urban and agricultural areas in central and southern Arizona via a 330-mile canal. Colorado River water is a high quality source but will minimally require treatment for turbidity removal and disinfection in order to meet federal, state and municipal standards. In this research, ozone treatment of CAP canal water was investigated. A parametric study was conducted to evaluate the effects of Ozone dose, aluminum sulfate dose and mixing conditions on turbidity and particle removal, organic carbon removal and filtration characteristics. Fluctuations in raw water quality were substantial over the sampling period of several months. At a 95% confidence level, turbidity removal by filtration depended on alum dose and rapid mix duration. Particle removal and TOC removal by filtration depended on ozone and alum doses as well as mixing time. Substantial removal of organic carbon, did not occur, but the mechanism of removal was found to be adsorption and subsequent filtration. In pressurized filtration tests, volume throughput was found to be dependent on ozone and alum doses, with higher alum doses resulting in decreased filtration.
