Abstract

LARRIVA VASQUEZ, Josué Bernardo  and  GONZALEZ DIAZ, Orestes Arsenio. Kinetics of BOD₅ removal in constructed wetlands with horizontal subsurface flow. riha [online]. 2017, vol.38, n.1, pp. 17-30. ISSN 1680-0338.

In the present work, studies are presented about horizontal subsurface flow in constructed wetlands for wastewater treatment in the Ecuatorian Andes, using different hydraulic retention times and different emerging plants. The application of the dispersion axial models and series tanks model to study the removal of Biochemical Oxygen Demand shows the importance of including geometric and hydraulic elements of the reactors in the design methodologies for horizontal subsurface flow in constructed wetlands.

Keywords : constructed wetlands; dispersion axial model; plug flow model; series tank model; BOD₅ removal.
