7 Wastewater Treatment Plant History The Springettsbury Wastewater Treatment Plant as it appeared in 1970 The Plant was Permitted for 8 Million Gallons Per Day

8 Wastewater Treatment Plant History In 1984 the Wastewater Treatment Plant Underwent an Upgrade and Expansion to 15 Million Gallons Per Day

10 BNR Upgrade Project Why Upgrade in 2011? PA DEP Bay Strategy Biological Nutrient Removal (BNR) Reduce Nitrogen and Phosphorous discharges to the Chesapeake Bay

11 BNR Upgrade Project 2011 BNR Upgrade BNR Strategy The main goal of this project was to design a BNR system that would meet the new effluent requirements without incurring the substantial expense of building new tanks (about 25 % more expensive).

12 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

13 BNR Upgrade Project Kruger IFAS System Media Facts -38% Fill -85,000 CF SF/CF -23M SF ACRES

14 BNR Upgrade Project BNR System Site Plan Anoxic Stage #1 (N1) Oxic Stage #3 (N3) Internal Nitrate Recycle To 2 nd Clarifiers Sludge Digesters (N4) Influent RAS North Train South Train Anaerobic Oxic (IFAS) Stage #2 (N2) Anaerobic Anoxic Stage #1 (N1) Oxic Stage #3 (N3) Sludge Digesters (N4) Oxic (IFAS) Stage #2 (N2)

15 BNR Upgrade Project - 50 Screens -16 Diameter -10 Long Media Retention Screens

16 BNR Upgrade Project Additional Upgrades Required New High Efficiency Diffused Air System Blowers and Blower Building Internal Mixed Liquor Recycle Pumps Conversion of Primary Clarifiers to Anaerobic/ Anoxic Selectors (anaerobic portion for phosphorous removal; anoxic portion for nitrogen removal)

17 BNR Upgrade Project Additional Plant Considerations Motor Control Center (MCC) Upgrade Emergency Power Upgrade Final Clarifier Improvements Current Density Baffles Algae Control System Headworks Screening System Upgrade Relocated Septage Dump Station

18 BNR Upgrade Project Influent Screening is CRITICAL 3 mm opening
