CASE HISTORY: OZONE/HYDROXYL ION MIST ODOR CONTROL SYSTEM UTILIZATION ON WASTEWATER COLLECTION SYSTEM AND TREATMENT PLANT ODORS
Abstract:The Hampton Roads Sanitation District operates nine wastewater treatment plants in Southeastern Virginia that individually treat between 10–40 million gallons per day (MGD) and collectively treats approximately 165 MGD of wastewater. HRSD's interceptor system covers a 2,100 square mile service area, has an estimated 500 miles of pipe (80% forcemain and 20% gravity) and includes 80 pump stations (15 of which employ odor control). Both the pump stations and the treatment plants have historically used packed tower wet scrubbers utilizing sodium hydroxide (caustic) and/or sodium hypochlorite (bleach) for odor control.
