MBR allows for treatment of peak flows with a small plant footprint.

DESCRIPTION

The city of Dover, OH originally built its wastewater treatment facility in 1956, with upgrades and in 1968, 1992, and 2001. Beginning in 2004 the city began to plan an expansion to accommodate population growth and to plan for more stringent environmental requirements. With rainfall and population growth, the peak monthly flow was projected to rise from 1.5MGD in 2001 to 2.5MGD in 2012. The new MBR facility, commissioned in March 2008 is actually capable of processing an average 3.0MGD with a peak of 6.0MGD. The 12,000mg/L MLSS and the membrane separation process in place of conventional clarifiers allows the MBR to have a smaller footprint than the previous facility with a higher flow capacity.
