This study compares the performance of a field bioretention cell with and without an internal water storage (IWS) layer for treating highway runoff. Both synthetic and natural runoff tests were conducted. Hydraulic performances on peak discharge reduction and detention time extension were measured. Pollutant removal efficiencies were evaluated for total suspended solids (TSS), copper (Cu), lead (Pb), zinc (Zn), total nitrogen, nitrate, ammonia, total phosphorus, and orthophosphate phosphorus… 

Phosphorus and TSS Removal by Stormwater Bioretention: Effects of Temperature, Salt, and a Submerged Zone and Their Interactions

To prevent deterioration of receiving water bodies, phosphorus and total suspended solid (TSS) removal from stormwater is commonly targeted, e.g., by bioretention. However, their removal may vary due

Design and operation of submerged layer in bioretention for enhanced nitrate removal

Bioretention, initially designed for treating discontinuous runoff pollution, faces considerable challenges in its trade-off between the hydraulic retention time (HRT) and its treatment capacity.

Modified Bioretention for Enhanced Nitrogen Removal from Agricultural Runoff

AbstractBioretention has been found to treat many pollutants, but nitrogen is difficult to control. A modified bioretention system with an internal water storage zone to encourage denitrification was

Effect of plant species on accumulation and removal potential of copper, zinc and lead from stormwater bioretention systems

ABSTRACT: Plants are known to take up pollutants from water and soil. The metal concentration of stormwater runoff is relatively low compared to industrial waste and mine tailings, however, continual



Performance of Bioretention System in Treating Urban Highway Runoff:A Comparison Study of Designs with and without an Internal Water Storage Layer

This study evaluated the performance of two bioretention systems in treating synthetic highway runoff.The experiments were conducted on Texas AM Riverside Campus located in Bryan,Texas,an area

Laboratory Study of Biological Retention for Urban Stormwater Management

Overall results support the use of bioretention as a stormwater best management practice and indicate the need for further research and development.

Water Quality Improvement through Bioretention: Lead, Copper, and Zinc Removal

Overall, excellent removal of dissolved heavy metals can be expected through bioretention infiltration, although the accumulation of metals is a concern.

A Field Evaluation of Rain Garden Flow and Pollutant Treatment

Rain gardens have been recommended as a best management practice to treat stormwater runoff. However, no published field performance data existed on pollutant removal capabilities. Replicated rain

Field study of the ability of two grassed bioretention cells to reduce storm-water runoff pollution.

Two grassed bioretention cells including internal storage zones (ISZs) were monitored for 16 months in central North Carolina. Each cell had a surface area of 106 m2 and fill media depths were 0.75

Evaluating bioretention hydrology and nutrient removal at three field sites in North Carolina

Three bioretention field sites in North Carolina were examined for pollutant removal abilities and hydrologic performance. The cells varied by fill media type or drainage configuration. The field

Evaluation of Bioretention Nutrient Removal in a Rain Garden with an Internal Water Storage (IWS) Layer

Stormwater runoff has been identified as a major source of pollution in urban and suburban streams. There are several innovative stormwater practices that integrate stormwater infiltration and

Bioretention Technology: Overview of Current Practice and Future Needs

Bioretention, or variations such as bioinfiltration and rain gardens, has become one of the most frequently used storm-water management tools in urbanized watersheds. Incorporating both filtration

Sustainable Oil and Grease Removal from Synthetic Stormwater Runoff Using Bench‐Scale Bioretention Studies

Results indicate the effectiveness and sustainability of placing a thin layer of mulch on the surface of a bioretention facility for reducing O&G pollution from urban stormwater runoff.
