Abstract |
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. The 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 pre-retrofit data are included in the report. |
