Stony Point was the first high capacity MPAC plant.
DESCRIPTION
In order to reduce engineering and construction time, a 125,000 gpd MPAC modular MBR with concrete tanks was selected. It contains a three process design with anoxic, aeration, and membrane zones. Beyond the small footprint and consistently good effluent quality, the MBR was selected for its ease of operation and limited operator input, as it is located in a remote location.
