Abstract: This study examines in situ phosphorus treatment using a combined unit operation and process, a volumetric clarifying filter VCF. Urban rainfall-runoff transports phosphorus in dissolved and particulate phases with the latter phase distributed across the particulate matter PM gradation. From a clean initial condition, the VCF was monitored across 19 events without maintenance, t…
Abstract: As a unit operation, filtration generally requires flow equalization and primary clarification. This study examines the separation of runoff particulate matter (PM) in a volumetric clarifying filter (VCF). The VCF is a detention/retention vault integrating filtration after sedimentation. A paved source area (1,088 m2) directly loaded the vault (4.2 m3) with five radial filte…
