Resumo

The present article has as aim to evaluate the efficiency of Vetiver grass in removing nutrients present in wastewater. The experiment was conducted at the Research Station for Sewage Treatment Plants, located in Sewage Treatment Plant, Goiania-GO. The experimental unit is composed of twelve treatment modules, filled with superposed layers of substrate. Six modules were vegetated with Vetiver grass and six modules remained without plants. For a period of 200 days, samples were collected from sewage before and after treatment and analyzed for the determination of ammonia nitrogen and total phosphorus, and calculation of efficiency in their removal, considering the rates of evapotranspiration. The results were subjected to F tests and Tukey at 5% probability. The treatment of the plant with the presence and level of sewage H1 showed higher efficiency in removing the nutrients load, and 90.5% for total phosphorus and 93.9% for ammonia.
