Wastewater Treatment Plant History
The Springettsbury Wastewater Treatment Plant as it appeared in 1970
The Plant was Permitted for 8 Million Gallons Per Day
![Page 8: SPRINGETTSBURY TOWNSHIP](https://reader033.vdocument.in/reader033/viewer/2022061409/56815a6e550346895dc7ce9e/html5/thumbnails/8.jpg)
Wastewater Treatment Plant History
In 1984 the Wastewater Treatment Plant Underwent an Upgrade and Expansion to 15 Million Gallons Per Day

BNR Upgrade Project
Why Upgrade in 2011?
PA DEP Bay Strategy
Biological Nutrient Removal (BNR)Reduce Nitrogen and Phosphorous discharges to the Chesapeake Bay
![Page 11: SPRINGETTSBURY TOWNSHIP](https://reader033.vdocument.in/reader033/viewer/2022061409/56815a6e550346895dc7ce9e/html5/thumbnails/11.jpg)
BNR Upgrade Project
2011 BNR Upgrade
BNR Strategy The main goal of this project was to design a BNR systemthat would meet the new effluent requirements withoutincurring the substantial expense of building new tanks (about 25 % more expensive).
![Page 12: SPRINGETTSBURY TOWNSHIP](https://reader033.vdocument.in/reader033/viewer/2022061409/56815a6e550346895dc7ce9e/html5/thumbnails/12.jpg)
BNR Upgrade Project
Integrated Fixed Film System (IFAS) Conventional Aeration Systems – Microorganisms
are suspended in tank IFAS Systems – Microorganisms are attached to a
suspended media; media offers greater surface area for microorganisms to grow
More microorganisms: Provide higher degree of treatment Can offset the need for additional aeration
basin capacity
