Description:
In the summer of 1982, the Hartford Metropolitan District Commission, Hartford County, Connecticut, Water Pollution Control Facility underwent a retrofit form a spiral roll coarse bubble to a full floor coverage fine pore aeration system. Work performed included all new in-tank piping and diffuser equipment and the installation of new filters on the blower air intakes. From November 1985 through August 1987, on-site studies were performed using off-gas analysis as part of the ASCE/EPA Fine Pore Aeration. This report presents the results of over 340 off-gas tests together with a case history of the retrofit to upgrade the aeration system. Historical information, retrofit evolution and implementation, aeration performance after the retrofit, cleaning and maintenance experience, and comparison of performance with preretrofit data are included in the report. This report was submitted in partial fulfillment of Cooperative Agreement No. CR812167 by the American Society of Civil Engineers under subcontract to Aeration Technologies, Inc. under the partial sponsorship of the U.S. Environmental Protection Agency. The work reported herein was conducted over the period of 1985-1987. Project summary may be ordered as EPA/600/S-94/001).
