Abstract
Modifications were made to an existing wastewater wetland treatment system to improve its effluent quality. Modifications included installation of baffles in the pond and the planting of selected plant materials. Removal efficiencies for BOD, ammonianitrogen, TSS and phosphate were monitored and shown to be influenced more by water temperature, loading rate and hydraulic retention time than presence of sparsely established vegetation. This study shows that the plant materials selected were inappropriate for use in wetland systems for wastewater treatment systems in mid-Missouri. Also, the presence of bottom sludge in the wetland system prevented the propagation of the selected plants.
