• Sanitaire SBR System Boosts Capacity, Reliability Without Building A New Facility

  Jefferson City, the Capitol of Missouri, has operated a sanitary sewage collection system dating back to the 1800s. The generations of infrastructure included a trickling filter treatment plant that first entered service in 1967 and underwent major upgrades involving screening, primary clarification, and secondary treatment over the course of 1969-77.

• A Model Integration Of State-Of-The-Art Technologies That Satisfied Both Initial And Long-Term Considerations

  The surrounding areas of Rock Creek Public Sewer District of Jefferson County, Missouri experienced substantial development in recent years overloading existing privately owned wastewater plant capacities.

• Olathe, KS Cedar Creek Plant Boasts The First In-Line Fermenter In The Country

  The City of Olathe is located just outside of Kansas City and is home to a growing population of 126,000, making Olathe the fifth most populous city in Kansas. Residents depend on the local Cedar Creek Wastewater Treatment Plant (WWTP) to meet their water demand.

• CASPERON Solution Brings Process, Operation And Cost Benefits To Michigan Facility

  For 15 years, plans to double the capacity of Michigan’s Zeeland Clean Water Plant remained stalled as the City of Zeeland worked toward a joint wastewater treatment contract with two neighboring Ottawa County communities. As a result, maintaining efficient aeration control posed a challenge for the 1.65 million gallons per day (MGD) facility. When expansion plans moved forward in 2016, the city alleviated those problems with the Xylem Sanitaire CASPERON activated sludge solution process, which eliminated the use of lime to treat waste and significantly reduced the volume of biosolid residuals.

• Aerobic Digester Reduces Nutrient Return And Improves Energy Efficiency

  Faced with rising operational costs due to increasing energy and chemical prices, as well as stricter effluent permit limits, many operators and engineers are turning to performance optimizers and controls automation to enhance treatment processes and reduce operating costs while limiting capital expenses.
