“…Particulate P could be trapped by the soil mix as it filters through the columns, while soluble organic P could remain in the treated runoff and flow out into receiving waterbodies. Similar results were observed in Lucas and Greenway's [3] study, where 97% PO4 3− -P removal was reported as compared to only 93% removal of total dissolved P.…”

“…Column 1 containing 100% sand demonstrated limited capacity in retaining TP. TP removal deteriorated sharply beyond a TP load of 3.01 g/m 3 . This corresponded to bioretention studies that documented sandy media (at 85% sand by weight) could be exhausted after only five years' worth of TP loads from typical urban runoff [5].…”

“…This was followed by a 2-cm height of small gravels (particle size range of 1.5-3.0 cm) and a 20-cm height of soil mix as the filter media. This arrangement provided an effective empty bed volume of approximately 182 cm 3 .…”

“…The use of WTR to control excess P in runoff as a result of fertilizer, manure or biosolids application in agricultural land has been receiving increasing attention [1,2]. More recent applications focus on the use of WTR in soil media of bioretention systems, more commonly known as rain gardens, to remove phosphate content from urban runoff [3]. In bioretention systems, plants only contribute to less than 20% of P retention, and therefore, WTR amendment could aid in long-term P removal [4].…”

“…The P adsorption capacity of WTR is notably higher than other materials evaluated for P removal. These include red mud and Krazonem soil, which are native to Queensland, Australia and the U.S., respectively [3]. Likewise, the P adsorption capacities of perlite, zeolite and granular activated carbon (GAC) [9] are also lower than that of Al-WTR.…”

Aluminum-based water treatment residue (Al-WTR) generated during the drinking water treatment process is a readily available recycled material with high phosphorus (P) adsorption capacity. The P adsorption capacity of Al-WTR generated from Singapore's water treatment plant was evaluated with reference to particle size range, adsorption pH and temperature. Column tests, with WTR amendments in sand with and without compost, were used to simulate the bioretention systems. The adsorption rate decreased with increasing WTR sizes. Highest P adsorption capacity, 15.57 mg PO4 3− -P/g WTR, was achieved using fine WTR particles (>50% particles at less than 0.30 mm). At pH 4, the contact time required to reduce effluent P concentration to below the detectable range was half compared with pH 7 and 9. The adsorption rate observed at 40 ± 2 °C was 21% higher compared with that at 30 ± 2 °C. Soil mixes amended with 10% WTR and compost were able to maintain consistently high (90%) total phosphorus (TP) removal efficiency at a TP load up to 6.45 g/m 3 . In contrast, TP removal efficiencies associated with columns without WTR amendment decreased to less than 45% as the TP load increased beyond 4.5 g/m 3. The results showed that WTR application is beneficial for enhanced TP removal in bioretention systems.

The use of biochar as a filter medium amendment has shown potential for removing organic and inorganic pollutants from wastewater. The purpose of this study was to investigate the effect of biochar particle size on: (i) removal efficiency of total phosphorus (TP) from wastewater; (ii) stability of the system under overloading and flooding conditions; and (iii) desorption potential of phosphorus from the filtration medium under inundation conditions. Biochar was prepared in two different sizes: fine and coarse with a mean diameter size of 0.31 and 0.49 mm, respectively. Two treatments using sand augmented with 8% by weight fine biochar (sand–FBC) and sand augmented with 8% by weight coarse biochar (sand–CBC) were tested. The TP removal efficiency of sand–CBC was 10% higher than sand–FBC medium. The average removal efficiencies were 83.3 ± 3.2 and 75.7 ± 7.4% for sand–CBC and sand–FBC media, respectively. Positive correlations between TP load and removal efficiencies were observed. All treatments showed resilience to overloading, flooding, and inundation conditions.
