Leoni Township WWTP Adds Capacity, Upgrades to Cutting Edge Treatment Process
|
| |
|
The Leoni Township Wastewater Treatment Plant (WWTP) was facing serious problems when Infrastructure Alternatives took over operations and maintenance responsibility in November 2005. The aging lagoon system was being overtaxed by a greater flow volume than it could properly treat. Excessive biosolids build up in the lagoons only exacerbated the problem.
Leoni Township began plans to build a new mechanical plant. A membrane bioreactor (MBR) facility was selected, which is a highly sophisticated wastewater treatment process, in direct contrast to the former lagoon system. Construction of the new plant was begun in the fall of 2008. (See photos of the new plant at left) The activated sludge process was seeded with return activated sludge from the Lansing, Michigan WWTP in early June 2010. The first discharge of effluent (treated water) from the new MBR plant occurred on June 17, 2010. The plant will be transitioned from start-up mode of operations to full operations when the mixed liquor concentration in the reactors reaches 8,000 mg/L, which is anticipated to happen sometime in late August or early September 2010.
The start up process has been successful to date, with the problems encountered typical of new mechanical plant start-ups. Tom High, Infrastructure Alternatives’ Plant Manager for the Leoni Township WWTP, has said of the new plant and the start up process, “This start-up has had challenges, but we (Infrastructure Alternatives’ plant staff) have been able to work cooperatively with the construction management team to pro-actively address issues.”
Infrastructure Alternatives’ Leoni Township WWTP staff is led by Plant Manager Tom High, a Michigan Class A licensed wastewater treatment operator, which is the highest classification a municipal wastewater treatment operator may earn in Michigan. Joining Tom are Operations Specialists Chris Crenshaw and Jared Driscoll.
Kent Trierweiler, P.E., Infrastructure Alternatives Vice President for Total Water Management, has said of the new plant and plant staff, “All have been focused on a successful start-up and transition into full operations, and Infrastructure Alternatives' main office staff has only provided support as needed. The plant staff has been very responsive to the construction manager and contractor to keep the start-up schedule on track. We are confident things will continue to progress toward a very successful outcome with this new and complicated plant and Leoni Township’s customers will be very well served with this state-of-the-art plant well into the future.”
