Abstract
A pilot subsurface constructed wetlands system in a cold climate region was monitored from late October 1996 to early September 1997 for BOD5, TSS, FC, NH3/NH4-N, NO2/NO3-N, TP, and TOC. The system components are: an upflow anaerobic filter with an automatic dosing siphon tank, a vertical (down flow) aerobic filter, a constructed subsurface wetland followed by an automatic dosing siphon tank, and infiltrators. In general, reduction of BOD, FC, TSS, and TP is observed as the effluent passes through the system, and reduction was higher in the summer than in the preceding winter and spring. Significant nitrification is not observed.
