DESCRIPTION
The Early Learning Center needed a small, modular treatment system that would be quick to install and easy to operate. The Ovivo MPAC small MBR system (9,000 gpd) was selected to satisfy these requirements. Precast concrete tanks where installed below grade to minimize the aesthetic impact, with equipment installed under an open enclosure to provide easy access. The plant is small, simple, and easy to operate.
