Vegetated biofiltration system (VBS) is an effective green technology for urban stormwater and greywater treatment. However, VBS yet to be optimised treatment of wastewater, particularly if it contains trace organic chemicals (TrOCs). The effect plant species has not been addressed under TrOC wastewater loading. This study tested evaluated the effectiveness over a one-year period in removing six TrOCs commonly found namely Caffeine (CAF), Paracetamol (PCM), Sulfamethoxazole (SMX), N diethyl‑meta-toluamide (DEET), Bisphenol A (BPA) Ibuprofen (IBU). Eleven configurations were year-long laboratory column explore role seven different (with differing characteristic), varied soil media depths, characteristics, on fate systems. operational conditions (e.g., dosing volume regime) removal efficiency was investigated. results indicated able maintain high rate (>95 %) CAF, BPA, IBU throughout experiment, followed by PCM (>79 %), SMX (50 %-80 DEET (<12 %). Plant significantly impacted (p<0.05), with C. indica as best performer. Reducing hydraulic loading decreasing daily frequency contributed positively PCM, SMX, rates. Noticeable accumulations DEET, BPA (8.2, 43.1, 54.5 ng·g-1, respectively) detected filter media, within saturated zone. Higher chemical concentrations (i.e., CAF DEET) root tissue than shoot tissue. offers valuable insights into VBS's design aspects TrOCs.
