Alum sludge, a largely available by-product of drinking water facilities using aluminium salts as coagulant was used as the media. Under a hydraulic loading rate of 1.27 m3/m2.d and a range of organic loading rate of 279.4–774.7 g-BOD5/m2.d and 361.1–1028.7 g-COD/m2.d, average removal efficiencies (mean ±SD) of 90.6 ±7.5% for BOD5 and 71.8 ±10.2% for COD were achieved, respectively. P removal was exceptional with average removal efficiency of 97.6 ±1.9% achieved for soluble reactive P at a mean influent concentration of 21.0 ±2.9 mg/l. Overall, the system holds great promise as a novel CWs for simultaneous removal of P and OM, and at the same time, it transforms alum sludge from a waste into a useful material.||Funding Details:||Other funder||Type of material:||Journal Article||Publisher:||Elsevier||Copyright (published version):||2010 Elsevier Ltd.||Keywords:||Alum sludge;Constructed wetlands;Phosphorus;Tidal flow;Self organizing maps||Subject LCSH:||Water treatment plant residuals
