As required by Colorado law, the treatment plant must begin planning to expand its facility. The plant currently treats 2 million gallons per day (mgd) and must expand to 6 mgd. This project team was hired to research treatment options for the advanced water treatment processes at the plant, phosphorus removal and disinfection. Using a cost-benefit analysis, treatment options for each process were researched and evaluated and the best alternative was chosen. A conceptual design for these operations was prepared as well.enghttps://creativecommons.org/licenses/by/4.0/Wastewater Treatment in Parker, Coloradothesis
