Iron and manganese in sediments of constructed wetlands with horizontal
Original language description
In 2008, concentrations of iron and manganese in the sediments of seven constructed wetlands (CWs) with horizontal subsurface flow in the Czech Republic were evaluated. The surveyed constructed wetlands varied in the length of operation between 2 and 16years at the time of sampling. In each constructed wetland three samples of sediment were taken in the inflow, middle and outflow zones to the depth of 0.6 m. The sample was divided into top (0?20 cm) and bottom (20?60 cm) sections, resulting in a totalnumber of 18 samples in each system. The survey revealed that the amount of sediments in the filtration bed increases with the length of operation. In general, more sediments were located at the bottom layers due to the wastewater distribution near thebottom. Concentrations of manganese in the sediment were highest in the new systems and decreased with length of operation. With the exception of one CW, in all other constructed wetlands Mn concentration in the sediment was significantly h
