Abstract

The root treatment wetland (RTW) is a low cost option to wastewater treatment, which efficiency depends on support material, wastewater composition, macrophyte specie and hydraulic detention time (HDT). This paper aimed to test the performance of the hydrometer and the volumetric method (VM) on measurement of effluent flow, and the removal efficiency of different macrophyte species over physical and chemical effluent attributes. The wastewater was from the bathrooms and restaurant in the experimental farm of the University of Brasília. Four constructed wetlands were used: free water system (FWS), RTW with Cyperus giganteus, with Typha spp and with Heliconia rostrata. The evaluation occurred in four days isolated. The systems’ potential evapotranspiration (PET) was determinate by the quocient of affluent-effluent volumes balance and the wetland surface area. The hydrometer didn’t measure affluent flow properly, recommending the VM. The highest PET was on RTW-Typha spp (9.98 mm day-1), followed by C. giganteus (9.37 mm day-1). The highest HDT was 9,49 days and the lowest was 4.68 days. The dissolved oxygen, pH, turbidity and total solids content are fit the Brazilian legal requirements for release into class 2 receiving bodies.
