The Ovivo microBlox MBR solved a real problem.
DESCRIPTION
A wastewater feasibility study of the Tule River Reservation by the Indian Health Service concluded that 30 percent of all septic tank/drainfield systems had failed and an additional 30 percent would fail in the near future. To correct this problem, the tribe decided to install an Ovivo microBlox MBR System. The microBlox was chosen for its small footprint, ease of installation, and future expansion. The plant will provide service for 850 residents. The microBlox is a single pass, high MLSS MBR utilizing concentrated oxygen for process purposes.
