Rob leads our nutrient management and TMDL compliance strategy team, applying his nationwide experience in advanced nutrient removal design; treatment process evaluation; bench-scale and pilot plant testing; operational optimization and construction of advanced treatment facilities. Rob’s advanced engineering studies, research experience and professional certifications enable him to provide outstanding support to our public and private sector clients. His comprehensive knowledge of TMDL load allocation principles; active involvement with the Virginia nutrient credit exchange; and experience working with water reuse and treatment residuals management enable him to provide exemplary program support to enabling our clients to cost effectively meet water quality objectives.

Aaron has experience in advanced BNR process modeling, preliminary engineering reports and detailed design and construction administration of municipal wastewater biological nutrient removal and tertiary treatment facilities to meet strict effluent nutrient limits (TN < 3 mg/l; TP < 0.1 mg/l). Aaron’s experience include experience includes biological nutrient removal design of four stage and five stage Bardenpho systems, tertiary treatment design of physical-chemical processes, including deep bed and cloth media filters and reactor-clarifiers, used to achieve low (< 0.1 mg/l) effluent phosphorus concentrations and membrane bioreactors (MBR) to achieve limit of technology limits for both TN and TP. Aaron also has experience in solids handling, thickening, and dewatering. He also has experience in conveyance and collection system design and modeling.
