The objective of this research was to evaluate the efficiency ofconstructed wetlands systems
(SAC’s) grown with Heliconiapsittacorumin comparison to a control SAC (without cultivation) in
the treatment of wastewater swine. The SAC’s weresubmitted to an organic loading rate of 100
kg ha-1d-1, based on the mean value of the Biochemical Oxygen Demand (BOD) of the swine
wastewater. In order to evaluate the efficiency of the systems, BOD, Total Solids (ST), Suspended
Solids (SS), Turbidity (T), and Total Nitrogen analyzes were performed in the effluent and
effluent to the SAC’s every 15 days during Systems. The average efficiency in the removal of
the variables was calculated from the influent and effluent concentrations and flows. The SAC
Heliconiapsittacorum did not present statistical differences (p<0.05) in relationtothewitnessin
the efficiency of removal of the evaluated attributes.
