Physico-chemical and water quality constituents were monitored at five sampling locations along the flow path of the CW. The greatest reduction in pollutant concentration was observed after passing the sedimentation zone at approximately 4% fractional distance from the inflow. The inflow hydraulic loading, flow rates and pollutant concentrations were significantly higher and variable during storm events than non-storm (baseflow) condition (p &amp;lt;0.001) that resulted to an increase in the average pollutant removal efficiencies by 10 to 35%. The highest removal percentages were attained for phosphate (51 \u00b1 22%), ammonium (44 \u00b1 21%) and phosphorus (38 \u00b1 19%) while nitrate was least effectively retained by the system with only 25 \u00b1 17% removal during non-storm events. The efficiency of the system was most favorable when the temperature was above 15 \u00b0C (i.e., almost year-round except the winter months) and during storm events. Overall, the outflow water quality was better than the inflow water quality signifying the potential of the constructed wetland as a treatment system and capability of improving the stream water quality.<\/jats:p>","DOI":"10.2166\/wst.2011.843","type":"journal-article","created":{"date-parts":[[2012,1,10]],"date-time":"2012-01-10T14:56:38Z","timestamp":1326207398000},"page":"119-126","update-policy":"http:\/\/dx.doi.org\/10.2166\/iwapcrossmarkpolicypage","source":"Crossref","is-referenced-by-count":17,"title":["Treatment performance of a constructed wetland during storm and non-storm events in Korea"],"prefix":"10.2166","volume":"65","author":[{"given":"M.
