An attempt was made to investigate the removal of high nutrient contents from polluted water. This study focused on the comparisons between nitrogen and phosphorus removal rates by area-based calculation and biomass-based calculation using various kinds of aquatic plants (18 emergent and 3 floating plants). Results showed that all floating plants performed maximum nutrient removal rates based on plant...
The effects of major operational factors on the performance of vertical-flow pilot-scale constructed wetlands (VFPCWs) were examined in parallel experiments. Experiments were conducted for one year in eight VFPCWs, the main substrate of which consisted of river sand at four of the wetlands, or a mixture of sand and dolomite (10:1 weight ratio) at the other four wetlands. Medium-strength synthetic...
