Oklahoma City’s Lake Hefner Water Treatment Plant is in the midst of a $48.5 million expansion project. The plant will be able to pump out 100 million gallons of tap water each day after the renovation, up from the current 75 million gallons. the growth of the city and surrounding areas has significantly increased demand for water requiring the expansion.
The project started this year and will be finished in 2013. The new facility will use ozone as a pretreatment prior to coagulation and flocculation. Ozone is being increasingly used in drinking water treatment for both disinfection as well as removal of contaminants from the water, e.g. taste and odor compounds, without creating undesirable byproducts.
