“…In fact, most of the early work conducted on P removal structures was in the context of municipal, domestic, and agricultural wastewater; the structures were often used in conjunction with treatment wetlands (Table 1). Different styles of P removal structures comply with these four characteristics, including surface runoff confined bed filters [12,13], PSM beds for wastewater [14,15], subsurface beds for wetlands [16][17][18], subsurface tile drain filters [11], enveloped tile drains [19,20], drainage ditch filters [21][22][23], modular perforated boxes [21], bio-retention cells [24,25] and blind inlets [26].…”

Controlling dissolved phosphorus (P) losses to surface waters is challenging as most conservation practices are only effective at preventing particulate P losses. As a result, P removal structures were developed to filter dissolved P from drainage water before reaching a water body. While many P removal structures with different P sorption materials (PSMs) have been constructed over the past two decades, there remains a need to evaluate their performances and compare on a normalized basis. The purpose of this review was to compile performance data of pilot and field-scale P removal structures and present techniques for normalization and comparison. Over 40 studies were normalized by expressing cumulative P removal as a function of cumulative P loading to the contained PSM. Results were further analyzed as a function of retention time (RT), inflow P concentration, and type of PSM. Structures treating wastewater were generally more efficient than non-point drainage water due to higher RT and inflow P concentrations. For Ca-rich PSMs, including slag, increased RT allowed for greater P removal. Among structures with low RT and inflow P concentrations common to non-point drainage, Fe-based materials had an overall higher cumulative removal efficiency compared to non-slag and slag materials.

“…The enhancements described above cause the state of the filter to change over time and modeling this change is only required for long term continuous simulation. The original filtration model has previously been used for bioretention cells (Li and Davis 2008;Liu and Davis 2014) where it was found to provide adequate results despite its underlying assumptions, which were: steady state conditions; single suspended particle size; single filter media grain size; and retained particles do not change filter properties.…”

A numerical tool was developed to calculate the stormwater runoff total suspended solids (TSS) removal efficiency of bioretention cells to assist engineers in obtaining credit and approval for bioretention cell facilities. Numerical models for filtration were used in developing this tool, as they have previously been successfully used for bioretention cells. The equations were adapted to integrate with the widely used USEPA SWMM, through its Add-in Tools feature. The tool was first tested to ensure the model matched the monitored performance of a bioretention cell and, second, benchmarked against the TSS removal predicted by another modeling tool (WinSLAMM). The capability of the tool to accurately simulate the TSS reduction performance of the monitored bioretention cell supports its suitability for use in designing bioretention facilities. This research, model development, and verification are the first steps towards the complete development of a stormwater runoff TSS removal model capable of continuous simulation, which will aid in bioretention cell design and installation.

The acceleration of urbanization has resulted in the increase of urban surface runoff. Bio-swale is a promising stormwater control measure that has been proven to be hydrologically effective on urban surface runoff. Column studies were conducted to determine the optimal bio-swale composition. Results demonstrated that water reduction was proportional to inflow decrease. Columns that planted border privet and Ophiopogon japonicus showed a larger water quantity reduction compared with that of planted boxwood and ryegrass, glossy privet and Chlorophytum comosum 'Variegatum' in vegetation tests, which was the same as the order of measured transpiration capacity of the plants. Water reduction rate increases dramatically with decreasing planting soil thickness. By contrast, no significant change occurs once the thickness of the artificial filler layer is altered. The bio-swale column with a high-infiltration rate artificial filler produced a good hydrological control effect. Sand was found to be the optimal media among the selected media compositions. Although the inclusion of an additional ponding depth affected total water reduction, it produced a stable outflow. SPSS software was used to assess the relationship between water reduction rate and its influence. On the one hand, water reduction rate increased linearly with increasing water inflow, soil thickness, and ponding depth. On the other, water reduction rate grew linearly with increasing plant factor and artificial filler infiltration rate. The multiple linear regression model revealing the relationship between the water reduction effect, and its influencing factors were obtained via the stepwise regression method in the SPSS software.
