•Case Study: Elected Changes Restore Compliance At Eunice, LA, Wastewater Treatment Plant
By Steve London
The activated sludge treatment process in its many variations is the most widely applied treatment process in municipal wastewater treatment plants due to its effectiveness and reliability. Reliable, that is, unless any one or more of the essential elements — healthy biomass, adequate mixing, and sufficient oxygenation — are out of balance to effectively treat a plant's influent stream.
Eunice, LA, offers a case in point, according to Bob Morris, the mayor of the town located in the Cajun heartlands of the state. His town's two plants have a 2.5-million gallons per day (MGD) combined design flow and receive influent from a 20-milelong collection system. The plants are operated manually by a five-man workforce, except for automated pump controls. Because the plants lack a Supervisory Control and Data Acquisition system, inspecting the utility's 16 pump stations is another daily duty. Scores of wastewater utilities still operate like Eunice and generally perform well if properly staffed, equipped, and maintained.
