Advancing Indirect Potable Reuse in Anne Arundel County Maryland by Validating Carbon-based Treatment Process for MAR
Abstract
With a view to meeting stringent nutrient goals and provide sustainable water solutions, Anne Arundel County in Maryland is evaluating indirect potable reuse through their Our wAAter Program. Managed aquifer recharge is being evaluated by treating secondary or tertiary effluent from the Water Reclamation Facility (WRF), by advanced treatment technologies. The finished water from this advanced treatment train will be injected in the aquifer. Results from initial sampling conducted at Patuxent WRF favored a carbon-based treatment train consisting of flocculation/sedimentation followed by ozone, biofiltration, granular activated carbon adsorption and UV disinfection. Data collected from this pilot will help in validating carbon-based treatment train and help with full-scale implementation.
Drivers such as stringent nutrient regulations and sustainable water solutions have made it imperative for some utilities on the East Coast to investigate and implement water reuse. This presentation will provide guidance on implementing a carbon-based advanced water treatment approach for indirect potable reuse. Water quality results from a WRF sampling plan, strategies for selecting an appropriate treatment train, and lessons learned from pilot startup and operation will be shared.
