“…A target quantity of infiltrated water needs to be defined in order to dismissthe experiment. The target quantity isestimated by using parameters such as the 1352 mm/year average annual rainfall in Korea [25], and an expected monthly maintenance frequency of filter facility in addition to the hydrologic parameters used in determiningthe dosing flow rate in the varying head condition. The resulting target quantity is equivalent to the amount of runoff treated by the infiltration facility for aone period of maintenance interval.…”

“…Filter bed design includes the presence of vegetation, and the characteristics of filter media such as shape, size, depth, and arrangement [11,18,20,21]. On the other hand, inflow characteristics pertain to the runoff inflow rates, sediment concentration, sediment particle size and distribution, and loading regime [22][23][24][25]. In this paper, the filtration performance and clogging possibility of sand-bottom ash mixtures with different mixing ratio were evaluated by conducting a series of 1-D column infiltration experiments.…”

Abstract:The performance of stormwater infiltration systems depends significantly on the infiltration/filtration characteristics of filter media. Sand media have been frequently used due to their abundance and acceptable pollutant removal efficiency. Bottom ash media, which was known to have a high sorption capacity, are being considered as alternative and/or complement filter media to enhance the overall treatment efficiency. To verify the applicability of bottom ash as filter media, a series of 1-D column infiltration tests were conducted in this study. The filtration and clogging characteristics of the sand-bottom ash mixtures at different mixing ratios were investigated with limitedly focusing on the Total Suspended Solids (TSS) present in stormwater runoff. As a result, the presence of bottom ash was identified to improve the TSS removal efficiency in spite of having a significant increase in clogging potential. All media configurations were observed to experience the premature clogging and the clogging state for varying and constant head flow conditions, respectively. The noticeable amount of crushed bottom ash particles brought by seepage force could be accountable for the rapid occurrence of clogging phenomena. Overall, a homogeneous sand filter is preferred as long as the lifespan of filter system is the primary concern.

“…Thus, TSS removal efficiencies using BA filter media were a complex function of particle size of BA filter media and loading rate of TSS, and BA2 (D = 6-10 mm) resulted in the greater TSS removal efficiencies and longer operational period in this study. Consistent with these results, the characteristics of both filter media (i.e., shape, size, depth, and arrangement) [4][5][6][7] and surface runoff (i.e., inflow rates, sediment concentration, sediment particle size, and distribution) [5][6][7][8] need to be considered to optimize the TSS removal efficiencies in infiltration/filtration facilities.…”

“…For stormwater BMPs, both hydraulic performances considering clogging risks and pollutant removal efficiency of filter media are key design parameters for stormwater filtration and infiltration systems utilizing various filter media (i.e., sand, soil, gravel, peat, or compost) with different surface area, depth, and profile [4][5][6][7]. Although filtration performance of various filter media is a complex function of the properties (i.e., arrangement, size distribution, surface area, and depth) of filter media [4][5][6][7] and the properties (i.e., particle size, distribution, and loading of sediment) of construction site runoff [5][6][7][8], the most widely used media is sand filters with high removal efficiency of particulates and with modest removal efficiency of bacteria and dissolved metals [7][8][9][10]. Since sand filters have greater adaptability by incorporating layers of other filter media to enhance pollutant removal efficiency, sand filters can be readily constructed either above or below ground as an end-of-pipe BMP or installed as basins or filter inlets [9][10][11].…”

The potential application of bottom ash (BA) for construction site runoff control as an alternative filter media with high removal efficiency of total suspended solids (TSS) and longer operation period were evaluated. Both lab-scale single-layer and pilot-scale multi-layer filtration experiments were performed using BA filter media with different particle sizes and various volumetric flow rates. Due to the mesoporous, irregular, and spherical shape of gravel-size BA filter media used in this study, relatively low surface area, negligible pore volume, and greater pore size were observed. Both TSS removal efficiencies and clogging of BA filter media were a complex function of particle size of BA filter media and loading rate of TSS. Incoming TSS particles did not significantly penetrate beyond 46-cm BA filter media depth, accumulating on the upper layers and gradually forming a clogging layer to critical thickness, and finally the clogging filtration mechanism dominated the overall removal efficiency of TSS. Accumulation of TSS on BA filter media can be explained by the lumped sigmoidal empirical model, and an exponential decline in accumulation of TSS with depth results in minimal accumulation beneath the clogging layer. As practical implications, BA filter media depth of less than 46 cm is recommended with dual- or multi-media filters using mixtures of gravel-size BA and silt-size fine media, and a combination of detention basins can reduce frequent periodic de-clogging operation and management.

Infiltration facilities are applied increasingly as effective BMPs to the urban stormwater control. The important functions of the facilities are surface flow reduction, contaminants elimination and aquifer recharge resulting from filtration, retention and infiltration of stormwater by porous media. A major obstacle in operating infiltration facilities is clogging. Filters of porous media in the facility are clogged by deposition of sediment over time. Clogging reduces infiltration rate and lifespan of the facility. Clogging, thus, needs to be considered as one of the important design factors in constructing infiltration facilities. In this study, 3 clogging models were chosen to simulate clogging, which developed in different disciplines, environmental and geotechnical engineering. Since the models were developed initially for fine media, applicability to coarse media interested in this study needed to be examined. To examine the applicability of models, analytical procedures of models were thoroughly reviewed. Parametric studies were also conducted to determine appropriate input parameters. Finally, the models represented relatively appropriate applicability to estimate clogging developed in an artificial infiltration as well as a real infiltration testing conditions. Although further studies are still needed for considerable aspects in input parameters and equations, the models could be suggested as effective analytical tools to estimate clogging developed in infiltration facilities of urban stormwater.
