The facility included the following major <br /> items: lift station upgrades; construction of grit and screenings removal; construction of aeration <br /> basins with biological phosphorous removal facilities; construction of new secondary clarifiers; <br /> construction of new chlorination and dechlorination facilities; construction of new aerobic <br /> biosolids treatment and storage facilities; and construction of a blower/control building. <br /> Additionally, in 2013 the City of Long Prairie and Bolton&Menk are <br /> completing an expansion of the extended aeration activated sludge <br /> system to accommodate additional industrial flow that needed to meet <br /> more stringent effluent limits. The existing industrial pond system is <br /> utilized for pretreatment and the extended aeration activated sludge <br /> facility is used to polish the additional flow. The expansion of the <br /> \ mechanical facility included the following major items: new lift <br /> station and forcemain;metering and control vault;third secondary <br /> . - ® clarifier; expansion of the chlorination and dechlorination system; <br /> automation of the phosphorous control system; expanded aerobic <br /> biosolids storage; alkalinity addition for nitrification; storm water improvements; and construction <br /> of new pumpingiblower building. For both projects, Bolton &Menk provided Facility Planning, <br /> Design, Construction Engineering and Start-up/Operations services as well as assisted the City in <br /> obtaining project funding from multiple sources. <br /> Wastewater Treatment Facility Improvements I City of Elk River, Minnesota 5 <br />
