SUMMARY:

Conventional wastewater treatment technologies, in general, do not remove satisfactorily nitrogen and phosphorus, nutrients responsible for the eutrophication of lakes, ponds and reservoirs. Bioclastic granules such as Lithothamnium calcareum have been widely used in rural areas and, due to their high porosity and high surface area, they have aroused interest in their use as an adsorbent in the treatment of effluents. This study aims to evaluate the removal of nitrogen and phosphorus from liquid effluents, using filters of this type of bioclastic granules on a bench scale. In order to estimate the concentration range of nutrients of interest, samples of effluent from ETE Piraí I, located upstream of the Vigário Reservoir in the Paraíba do Sul Basin, State of Rio de Janeiro, will be characterized. After performing the granulometric analysis of the adsorbent material, batch tests will be carried out for the perfect kinetic and thermodynamic understanding of the process. In this way it will be possible to know the nature of the adsorption process: as for its spontaneity and also as for the form of interaction between adsorbent and adsorbents. With these results, continuous tests will be conducted through filling beds in order to obtain the necessary parameters for its best operation. It is intended the end of this work get the kinetic and thermodynamic parameters characterizing the process as well as the parameters for the design of sewage post-treatment units in full scale.
