Abstract:

The Valrico Advanced Wastewater Treatment Plant (AWTP) is owned and operated by Hillsborough County, FL. The AWTP is rated for an Average Annual Daily Flow (AADF) of 4 mgd. The permit effluent limits are 5.0 ppm BOD5; 5.0 ppm TSS; 3.0 ppm TN; and 1.0 ppm TP. In order to accommodate the anticipated growth in the service area, the existing biological system was optimized to realize a 50 percent increase (4 to 6 mgd) in BNR capability without the addition of new aeration basin. Process optimization entailed (i) Implementation of tight DO control using on-line nutrient and DO analyzers to maximize simultaneous nitrification/denitrification, and (ii) Examination of the behavior of the clarification processes under various operating scenarios using the State Point approach. The opinion of probable cost and construction cost were 5 and 4.2 million, respectively. The upgraded facility was commissioned in June 2002, on schedule and under budget. Construction change orders were limited to less than 2 percent.
