Flow characteristics of constructed wetlands : tracer studies of the hydraulic regime

Creator:

Stairs, Darrin B.

Abstract:

Treatment efficiency in a constructed wetland is related in part to the amount of time that a wastewater remains in the system. Current design methods idealize the system as a plug flow reactor and use a "residence time" based solely on the volume of the cell and the flow rate....

Effect of plant surface area on organic carbon removal in wetlands

Creator:

Kuehn, Elaine Jinx

Abstract:

This study investigated the effect of plant surface area (plant density) on the efficiency of organic carbon removal in a bench-scale constructed wetland. Constructed wetlands are commonly assumed to be biofilm reactors in which organic carbon removal occurs primarily through sedimentation and aerobic degradation by attached microbial biofilms. In conventional...
