Volumetric Filtration of Rainfall Runoff. I: Event-Based Separation of Particulate Matter

---

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 filters (
4 m2 of filtration surface area). PM separation was examined for 19 runoff events through monitoring of influent and effluent granulometric fractions. During the monitoring phase no maintenance was conducted and subsequent to the 19 events a measured material balance of the sedimentation vault and the radial cartridge filters generated a 94% recovery of PM. During 5 months of monitoring and PM mass, suspended sediment concentration
SSC was reduced from 334 to 34 mg/L
(90% reduction) with effluent sediment
