The purpose of this analysis was to compare the actual performance of a wastewater treatment plant with the predicted operation of a wastewater treatment plant. The goal was to find out which operation process in the secondary system was limiting the treatment capacity of the plant and to eliminate that problem with some suggested upgrades and then to cost these upgrades. For this analysis, the Oconomowoc Wastewater Treatment Plant was chosen for study based on the fact that they have steadily operated under the same processes for the past several years and had reliable data readily available. The operating envelope methodology was selected for the analysis. This methodology takes into account aeration volume, clarifier capacity and oxygen transfer, developing an envelope of operation within which a plant can run within and not have operational problems. Under average flow and loading conditions, the plant was found to be operating outside of the envelope of operation due to a lack of aeration volume. A proposed upgrade is to add two additional aeration tanks to give the required volume to treat the waste. However, this proposed upgrade will create a need for additional oxygen since aeration volume is related to the necessary oxygen to treat the waste. In order to supply additional oxygen, an existing 75 horsepower blower must be replaced with a 100 horsepower blower. With these two upgrades, the plant should be able to operate effectively. The sludge pumps for the return and wasted sludge were checked and found to be within operating limits based upon the simulated maximum loadings. However, it would be recommended that a further study be done on the sludge thickeners as well as the solids holding facility to ensure they still have sufficient capacity to handle the increased solids loadings used for this analysis.   Copy/Holding information Location Collection Call No. Status   Walter Schroeder Library Master's Theses AC805 .M666 2003 Available Add Copy to MyList Format: HTMLPlain textDelimited Subject:   Email to:
