Water quality improvement through bioretention media: nitrogen and phosphorus removal.
High nutrient inputs and eutrophication continue to be one of the highest priority water quality problems. Bioretention is a low-impact development technology that has been advocated for use in urban and other developed areas. This work provides an in-depth analysis on removal of nutrients from a synthetic stormwater runoff by bioretention. Results have indicated good removal of phosphorus (70 ...
متن کاملNitrogen Chemistry in an Urban Bioretention System in Singapore
An investigation into the nitrogen chemistry of the anoxic layer of an urban constructed wetland in Singapore was conducted. This pilot-scale wetland treats stormwater runoff from the Balam Estate housing development for several water quality parameters of concern, including nitrate. Earlier sampling in the wetland had indicated that the concentration of nitrate was lower in the outflow from th...
متن کاملKinetic Modeling of Isothermal or Non-isothermal Adsorption in a Pellet: Application to Adsorption Heat Pumps
Understanding the interaction between a fluid and a solid phase is of fundamental importance to the design of an adsorption process. Because the heat effects associated with adsorption are comparatively large, the assumption of isothermal behavior is a valid approximation only when uptake rates are relatively slow. In this article, we propose to determine when it is needed to choose the isother...
متن کاملEngineered bioretention for removal of nitrate from stormwater runoff.
A bioretention unit is a simple, plant- and soil-based, low-impact treatment and infiltration facility for treating stormwater runoff in developed areas. Nitrate, however, is not attenuated in conventional bioretention facilities. Thus, this study systematically evaluated a reengineered concept of bioretention for nitrate removal via microbial denitrification, which incorporates a continuously ...
متن کاملFinding the Right Bioretention Soil Media
The successful functioning of a bioretention system depends on the use of suitable soil media. Predictive computer modelling of a bioretention system (e.g. using the MUSIC software) assumes specific characteristics of the soil media to achieve a certain level of stormwater treatment. Therefore, the soil media used in the construction of a bioretention system must exhibit the required characteri...
