15. Supplementary Notes Project performed in cooperation with the Texas Department of Transportation and the Federal Highway Administration. Project Title: Bioretention for Stormwater Quality Improvement in Texas URL: http://tti.tamu.edu/documents/0-5949-2.pdf 16. Abstract This report summarizes the results of pilot-scale bioretention experiments. Five steel boxes of 6 ft (L) × 6 ft (W) × 4 ft...

Aluminum-based water treatment residue (Al-WTR) generated during the drinking water treatment process is a readily available recycled material with high phosphorus (P) adsorption capacity. The P adsorption capacity of Al-WTR generated from Singapore’s water treatment plant was evaluated with reference to particle size range, adsorption pH and temperature. Column tests, with WTR amendments in sa...

In response to water quality and quantity issues within the Stroubles Creek watershed in Blacksburg, Virginia, a retrofit bioretention cell (BRC) was installed to collect and treat runoff from an existing parking lot. The BRC was completed in July 2007, and 28 precipitation events were monitored between October 2007 and June 2008. For each storm, inflow and outflow flow-weighted composite sampl...

Abstract Bioretention cells alleviate stormwater toxicity by permeation through soil media. Amending bioretention materials may result in increased chemical pollutant removal while maintaining hydraulic properties. Zeolite was tested media for zinc, copper, phosphorus, ammonium, and nitrate from synthetic a column study. Ecolite did not improve metal or phosphorus removal; however, significantl...

The FullSWOF-ZG (Full Shallow Water Overland Flow with infiltration determined by Zones and Grate-inlet submodules) program was used to simulate the road-bioretention (RB) stripe evaluate performance of RB three types curb inlet. revised from open-source FullSWOF-2D validation results indicated predicts accurately. model cases 27 different longitude slopes (S0), cross (Sx), inlet lengths (Lci) ...

Bioretention cells are popular stormwater management systems for controlling peak runoff and improving water quality. A case study on a functional large-scale bioretention cell laboratory column experiment was conducted to evaluate the concentrations retention efficiency of towards tire wear particles (TWP). The presence TWP observed in all soil fractions (<50 µm, 50–100 100–500 >500 µm) ...

Beyond the traditional use of ceria as an abrasive, the scope of nanoceria applications now extends into fuel cell manufacturing, diesel fuel additives, and for therapeutic intervention as a putative antioxidant. However, the biological effects of nanoceria exposure have yet to be fully defined, which gave us the impetus to examine its systemic biodistribution and biological responses. An exten...
