Transport and Treatment of Entrained Particulate Matter from Elevated Transportation Infrastructure by Rainfall-Runoff
A passive treatment system adopted from in-situ adsorptive-filtration systems was installed to treat storm water from an elevated section of Interstate 10 (average daily traffic count of 140,000) in Baton Rouge, Louisiana. Results indicate pollutant removal efficiencies of greater than 90% could be realized for total suspended solids (TSS), turbidity and total chemical oxygen demand (COD). Removal efficiencies were not affected by a highly variable influent composition or extended periods of non-operation between storms. Approximately 1000 pore-volumes were treated and breakthrough of TSS and COD mass in the clarifier effluent nor excessive head loss across the adsorptive-filter media clarifier was observed, indicating treatment capacity has not been exceeded. This study documents how the logistics of elevated highways over water influence the treatment performance viability and operational design of treatment strategies and in particular and the operation of a passive sorptive media clarifier (SMC) for storm water runoff from an elevated infrastructure.
