Filtration for Metals Removal from Stormwater
Filtration as a method of stormwater treatment was investigated in a 3-year study. Equilibrium and kinetic studies of metals’ capture were performed initially on twelve media. The three best performing media: peat-sand mix, compost, and zeolite were then selected for in-depth study. Upflow filters did not clog as easily as downflow, and longer-term performance was better in the upflow column. M...
متن کاملMetals Removal Technologies for Stormwater
This study, on innovative methods for the capture of metals from stormwater, focused on two major areas of investigation: media filters and swales. The test water for both the filters and the swales was a stormwater which was collected from a parking lot during wet weather events. The characterization of the stormwater showed that the most prevalent metals detected in the runoff were iron, zinc...
متن کاملThe Role of Traditional and Novel Toxicity Test Methods in Assessing Stormwater and Sediment Contamination
Traditional effluent and ambient water column toxicity tests have been used widely for evaluating the contamination of stormwaters and sediments. These assays consist of a routine bioassay exposure design of 1 to 9 days using freshwater and marine/estuarine species known to be sensitive to a wide range of toxicants. While effluent toxicity may be indicative of sediment or stormwater toxicity in...
متن کاملMetals Removal Technologies for Stormwater: Filtration
This study, sponsored by the Water Environment Research Foundation, focused on innovative methods for the capture of metals from stormwater. The two areas of focus were media filters and swales. This paper will focus on the filter studies. Twelve media were chosen for initial evaluation. Equilibrium and kinetic studies were formed on these media to assess their performance in capturing metals f...
