The aim of this study is to evaluate seasonal enhancement nitrogen removal on domestic wastewater treatment performance by partially saturated and HBCWs. To achieve this, two HBCWs consisting a vertical subsurface flow constructed wetland, followed horizontal wetland (VSSF-HSSF) were evaluated. Two saturation levels used: (a) HB1:VSSF1 (0.6 m)-HSSF1 (0.15 m), (b) HB2: VSSF2 (0.8 m)-HSSF2 (0.25 ...

Dynamics of bacterial community abundance and structure of a newly established horizontal subsurface flow (HSSF) pilot-scale wetland were studied using high-throughput sequencing and quantitative polymerase chain reaction (PCR) methods. Bacterial community abundance increased rapidly within one month and stabilised thereafter in three replicate HSSF constructed wetland (CW) mesocosms. The most ...

One measure used in Sweden to mitigate eutrophication of waters is the construction of small wetlands (free water surface wetland for phosphorus retention [P wetlands]) to trap particulate phosphorus (PP) transported in ditches and streams. This study evaluated P retention dynamics in a newly constructed P wetland serving a 26-ha agricultural catchment with clay soil. Flow-proportional composit...
