Abstract In April 1983, the Ridgewood, New Jersey Wastewater Treatment Plant underwent a retrofit from a coarse bubble to a fine pore aeration system. Also, process modification from contact stabilization to tapered aeration occurred. The report presents a case history of plant and aeration performance of each system from 1981 through 1986. Extensive aeration studies were conducted on the fine pore aeration system in 1985 and 1986 to highlight the changing oxygen transfer efficiency with time and evaluate cleaning frequency requirements to maintain the efficiency at a viable level. An economic evaluation including bid prices, maintenance costs, and payoff period based on power savings is included.
