摘要

The wastewater treatment system in the City of Phoenix consists of two plants at 23rd Avenue and 91st Avenue and serves five neighboring cities. The present treatment capacity available to these participating cities is 157 MGD. The current total energy bill for the two plants is approximately $2 million annually. After the expiration of contract with the utility company in 1984, the new rates are likely to mount the energy bill to $4 million annually. The object of this project is to study the feasibility of developing an energy conservation program for computerized automatic operation of the wastewater treatment system. This involves a study of variables in the system, economic automatic operation of equipment to reduce peak demands and effect optimum use of electric energy on a 24-hour, 7-day basis. 7 figs., 14 tabs.
