Ditch the Phosphorus
When staff at the wastewater treatment plant in Commerce Township, Mich., began upgrading the oxidation ditch facility, they had three major considerations: increasing installed capacity, meeting an effluent phosphorus limit of 0.1 mg/L, and keeping costs manageable.
Less Power, Great Performance
Membrane bioreactors are compact and provide high-clarity effluent without secondary clarifiers or filters, but as power costs continue to rise, their high energy use makes them difficult to justify on a life-cycle basis.
A Georgia treatment plant dealt with this challenge by modifying both the design and operations of its MBR facility to be more energy efficient.
