| Abstract | This study evaluated the performance of bioretention systems in terms of stormwaterrunoff quality improvement and hydraulic conductivity (Ks) efficiency. Three alternativebioretention designs were conducted under controlled conditions to compare betweennon-biochar-amended and biochar-amended reactors. Results demonstrated that the nonbiochar-amended reactor (R1) showed Ks values with an average of 251.12 millimetersper hour (mm/hr), compared to 269.98 mm/hr in the 5% biochar-amended reactor(R2) and 272.30 mm/hr in the 10% biochar-amended reactor (R3). Pollutant removalefficiencies varied significantly across designs. For R1, total suspended solids (TSS), totalnitrogen (TN), and total phosphorus (TP) were retained at 92.51%, 56.09%, and 99.20%,respectively. R2 demonstrated reductions of 95.81% for TSS, 43.13% for TN, and 84.89%for TP. R3 exhibited reductions of 99.78% for TSS, 62.05% for TN, and 92.40% for TP.These findings highlight that bioretention systems can effectively improve stormwaterrunoff quality, while biochar plays an important role in enhancing Ks. The results offervaluable insights for the design and optimization of bioretention prototypes, presentingscalable solutions for sustainable urban water management in Thailand. |
