The west and east biological treatment tanks operate in series with the wastewater influent entering the west tank. The fill pipe into the west tank was positioned such that the influent fell several feet to the liquid surface. Modeling indicated that organic compounds were stripped to the atmosphere due to the drop.
This project reduced approximately 38,000 lbs/yr of TRI emissions to air.
