WebTo enhance N removal, a 40 cm internal water storage zone (IWS) was installed at the bottom of the columns, which increased the retention time and created an anoxic zone for denitrification. As a result, the average TN and NO 3 − -N removal increased to ∼75% and ∼85%, respectively, with a retention time of 2 h regardless of the WTR. WebBioretention is a water management practice that is increasingly being applied for runoff quality control. Although previous Bioretention studies have used some techniques to improve nutrient removal, some nutrients still leach out. Therefore, this
