Abstract Text | The City of Perry is located in Taylor County, Florida. Currently, the City of Perry obtains source water from three supply wells. The City identified elevated disinfection-by-products (DBPs) in its distribution. The City began seeking to identify the exact source of the DBP precursors and ultimately identified source well No. 7 as having elevated levels of total organic carbon (TOC), a natural organic material which is a known DBP precursor. Well No. 7 (1,400 GPM capacity) is treated at the City of Perry Water treatment Plant No. 2, a 1.95 million-gallon per day (MGD) plant. The raw water from well No.7 also has elevated iron content and has been successfully treated for years at Plant No. 2 via a treatment train consisting of a cascade aerator, a detention tank, gravity (dual media) granular filters, a chlorine contact chamber, and a clearwell that houses the high service pumps. The cascade aerator, detention basin, and granular media is used to treat the iron in the raw water via precipitation of the iron as iron oxide, which is subsequentially filtered out by the direct filtration system. Due to the unique nature of the plant layout, a means of treating the water from well 7 for DBP precursors was not feasible prior to the filtration system. This resulted in requiring treatment post filtration and offered a novel location in the treatment train to provide DBP and TOC treatment. New components used to treat the DBP, and TOC consists of:
Key aspects of the project that will be discussed include:
The proposed improvements to the Perry water treatment Plant No. 2 are fully designed and permitted and are scheduled to go into construction in the beginning of 2023. |
