BMP FILTERS: UPFLOW VS. DOWNFLOW

Citation:

Clark**, S., R. Pitt, AND A. Balakrishnan. BMP FILTERS: UPFLOW VS. DOWNFLOW. Presented at ASCE Urban Water Resources Research Council/Engineering Foundation Conference, Snowmass, CO, August 19, 2001.

Impact/Purpose:

To inform the public.

Description:

Stormwater filters are typically operated in a downflow mode. This research had two objectives: 1) to determine the increased life of a filter operated in an upflow mode, and 2) to determine if the operation of a downflow, mixed-media filter could be modeled using the power equation proposed by Urbonas( 1999). The results showed that upflow operation could provide longer filter run times. Using laboratory-scale columns, the use of a power equation to model downflow filtration was also demonstrated. Model confirmation using pilot-scale columns is currently underway.
