Info

Hydrologic Benefits of Bioretention • Reduce peak flows • Reduce runoff volume • Reduce flooding • Convey stormwater to downstream receiving waters • Miti Maintain pre-development groundwater recharge • Mimic pre-development hydrology
Treatment Processes of Bioretention • Settling/Filtration Stokes’ Law Added benefit of dense vegetation and check dams • Sorption – Bioretention Media Absorption Adsorption Precipitation • Transformation ii i Bioretention Treatment Efficiencies: Bioremediation Phytoremediation Pollutant % Removal Suspended Solids 90% Total Phosphorus 70% to 83% Total Nitrogen 68% to 80% BOD 60% to 80% Lead 93% to 98% Zinc 93% to 98% Hydrocarbons 90%
