Project Details

Construction of two concrete pretreatment basins, with a common rapid mix system, flocculation equipment and clarification equipment. Filtration improvements included two gravity filters in concrete structures, two concrete washwater recovery tanks and associated pump room, wet well sumps, and tank equipment. The existing pre-treatment basin was converted to a building that houses ozone generation and off-gas destruction equipment, polymer blending, an engine generator, and future sludge dewatering equipment. A chemical storage building includes indoor and outdoor chemical storage tanks and outdoor liquid oxygen (LOX) storage on a concrete slab.
