Improvement and Optimization of the A. H. Weeks Water Treatment Plant Processes, Windsor, ON, Canada

Abstract

ABSTRACT After the ozone system was implemented at the A.H.Weeks Water Treatment Plant in June 2001, the plant was monitored to evaluate the effects that ozone had on the plant operation and filtered water quality. Filter performance showed an improvement since ozone was applied. Longer filter run time and lower filtered water turbidity and particle count were achieved. Average treated water turbidity was 0.07 NTU for the year before ozone was applied and 0.05 NTU for the year after ozone was applied. An optimization process was conducted to improve the operation. The benefits of the ozone system optimization resulted in more consistency in meeting performance objectives. Ozone generator power requirement was decreased while ozone generator efficiency was increased. Overdosing of ozone quenching agent was less frequent. Reduction in total operational cost was also observed for the year ozone was applied.
