The drinking water industry is constantly facing new increasing demands for the improvement of water quality. Disinfection criteria are concentrated on the inactivation of Giardia lamblia and viruses. At the present time, the inactivation of Cryptosporidium is unregulated in Canada, however, the presence of Cryptosporidium oocysts in source water (Detroit River) made the Windsor Utilities Commission decide to use ozone as its primary disinfectant. The ozone system at the A. H. Weeks Water Treatment Plant (WTP) is designed for a 2-log Cryptosporidium inactivation in the summer and 1-log Cryptosporidium inactivation in the winter. The ozone system was brought on-line in June 2001. The plant was monitored to see the effects that implementing ozone had on the plant operation and filtered water quality. An optimization process has been conducted to improve the operation of the ozone system at the A. H. Weeks WTP. Optimization included automation of the addition of ozone dosage using CT Trim Control, using the IDDF method approximation to calculate Performance Ratio, and the automation of the addition of quenching agent.
