Bioretention cells remove microplastics from urban stormwater

Water Research, 2021
Microplastic pathways in the environment must be better understood to help select appropriate mitigation strategies. In this 2-year long field study, microplastics were characterized and quantified in urban stormwater runoff and through a bioretention cell, a type of low impact development infrastructure.

Bioretention Cell Construction

2008 Providence, Rhode Island, June 29 - July 2, 2008, 2008
Eight bioretention cells were installed in Grove, Oklahoma in Summer 2007 as part of a technology demonstration and evaluation project. Cell design focused on phosphorus and nitrate attenuation by utilizing fly ash as an additive to the filter medium and incorporating a biozone or anaerobic zone, respectively.

Nitrogen transfer and transformation in bioretention cells under low temperature conditions

Science of The Total Environment, 2023
The nitrogen removal effect of traditional bioretention cells is generally poor under low temperature conditions, with significant levels of fluctuation and leaching often reported. Therefore, the migration characteristics of nitrogen were explored in bioretention cells under low temperature conditions, with the aim of improving the nitrogen removal ...

Construction and Performance of Bioretention Cells

World Environmental and Water Resources Congress 2009, 2009
Bioretention cell are gaining popularity as a stormwater best management practice (BMP). This can be largely attributed to the fact that they present a broad range of potential benefits such as decreased runoff, thermal attenuation, aesthetics and improved water quality through various physical, chemical and biological processes.

Bioretention Cell Design and Construction Specifications

2007 Minneapolis, Minnesota, June 17-20, 2007, 2007
Non-point source pollution is a major concern in many watersheds. Nutrients, heavy metals, and organic chemicals contained in NPS pollution negatively impact water quality due to the large volumes and widespread nature of the flow. Bioretention cells offer a means to reduce the velocity of the flow and reduce the pollutant load associated with NPS ...

Bioretention cell age and construction style influence stormwater pollutant dynamics

Science of The Total Environment, 2020
In urbanized landscapes, green infrastructure is proposed as a method for using relatively small plots of land to manage stormwater and protect receiving ecosystems from pollutants. Bioretention cells can infiltrate stormwater from roads and parking lots, and as stormwater passed through the soils, metals can be removed.

Pollutant Removal in Bioretention Cells with Grass Cover

World Environmental and Water Resources Congress 2007, 2007
North Carolina has spent considerable effort to improve water quality in the State and its estuaries. One area of focus has been stormwater runoff quality. Bioretention is often used to treat runoff from new developments and is retrofitted in areas where development has already occurred.

Impact of Hydraulic Conductivity Variability in Bioretention Cells

2010 Pittsburgh, Pennsylvania, June 20 - June 23, 2010, 2010
Bioretention Cells are an established and growing Best Management Practice for stormwater quality treatment. Cells work by filtering and temporarily storing stormwater. The cell filter media provides physical filtration, chemical adsorption and a platform for plant biological uptake or microbial degradation of some contaminates.

Nitrogen removal performance of bioretention cells under polyethylene (PE) microplastic stress

Environmental Pollution, 2023
The use of bioretention cells as a stormwater control measure allows stormwater runoff to be collected and filtered, effectively removing microplastics and other pollutants from stormwater. This study investigated the effect of polyethylene microplastics (PE-MPs) retention on the bioretention cell, in terms of denitrification performance and microbial ...

Effects of freeze-thaw cycles on nutrient removal from bioretention cells

Journal of Environmental Management, 2023
There have been numerous summaries of the runoff purification characteristics of bioretention cells in warm climates. However, little has been done on the effects of freeze-thaw cycles (FTCs) that frequently occur in cold regions on bioretention cell performance.
