“…On contrary, the amount of particle sizes < 50 μm were found to increase with depth. This result agrees with Wang et al (2012) wherein the accumulation of fine particles (0-38.5 μm particle diameter) increases with depth. It clearly agrees with the previous statement that the pressure increase due to water built up in the allowable ponding height has the ability to push and drive the small sediments particles deeper into the filter column.…”

“…Wang et al [39] stated that the degree and location of clogging in a filter system is greatly influenced by the size of the suspended solids. In response, the particle size distribution of the accumulated sediments along the depth of the filter column was analyzed.…”

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.

“…As suspended solids continuously accumulate in the flow channel of the medium, the number of suspended solids particles which have the capability to transport through the medium decreases. Suspended solids retention position accumulates upward, ultimately forming a clogging cake on the surface of the infiltration medium [31] (Figure 3c). This clogging mode is a special type of surface clogging that takes longer time to achieve the ultimate clogging state.…”

Abstract:The implementation and development of managed aquifer recharge (MAR) have been limited by the clogging attributed to physical, chemical, and biological reactions. In application field of MAR, physical clogging is usually the dominant type. Although numerous studies on the physical clogging mechanism during MAR are available, studies on the more detailed suspended clogging types and its prediction methods still remain few. In this study, a series of column experiments were inducted to show the process of suspended solids clogging process. The suspended solids clogging was divided into three types of surface clogging, inner clogging and mixed clogging based on the different clogging characteristics. Surface clogging indicates that the suspended solids are intercepted by the medium surface when suspended solids grain diameter is larger than pore diameter of infiltration medium. Inner clogging indicates that the suspended solids particles could transport through the infiltration medium. Mixed clogging refers to the comprehensive performance of surface clogging and inner clogging. Each suspended solids clogging type has the different clogging position, different changing laws of hydraulic conductivity and different deposition profile of suspended solids. Based on the experiment data, the ratio of effective medium pore diameter (D p ) and median grain size of suspended solids (d 50 ) was proposed as the judgment index for suspended solids clogging types.
