Plant Combines Wastewater Treatment and Energy Conservation   Water Engineering & Management October 2002   Robert T. McMillon and D.J. "Jody" Zabolio, III, P.E.
There are not many wastewater treatment plants that can look at naturally occurring organic waste and see a renewable source of energy. However, the Village Creek Wastewater Treatment Plant in Fort Worth, Texas, has done exactly that for the last 40 years. This last year, steps were taken that could make Village Creek a net energy producer instead of an energy consumer.

Fine Bubble Aeration/Mixing System Cuts Lagoon Treatment Energy Costs   Water & Wastes Digest August 2002
The Biomixer Aeration and Mixing system is providing optimum dissolved oxygen transfer and mixing at this lagoon, in spite of the number of units being reduced from the original design of five units down to three. This is being obtained with the dissolved oxygen levels throughout the basin averaging 9.1 mg/l. Even at the influent end of the basin where the loading rate is the highest, the dissolved oxygen readings were above 8.5 mg/l.
