MBR technology is very versatile and can handle variations in flow and loadings in a Casino on weekends
DESCRIPTION
Angel of the Winds Casino has an OVIVO MBR since 2004. With addition of a hotel, gas station, convenience store, RV park, laundry facility restaurant, and an administrative building and community centre they were maxed out on weekends requiring an expansion. A greenfield MBR was built to handle the increased flow and loadings. The old MBR facility will be reused for WAS storage and also some offline EQ for the peak instantaneous flows.
