1. Removal of microcystins in water from eutrophic reservoir involving technical of clarification, pre-oxidation with potassium permanangate, adsorption with powdered activated carbon and post-chlorination / Remoção de microcistina em águas provenientes de reservatório eutrofizado associando técnicas de clarificação, pré-oxidação com permanganato de potássio, adsorção em carvão ativado e pós-cloração
The present work had as objective to evaluate the removal of three different concentrations of extracellular microcystins in different combinations of water treatment for supplying, in bench scale, that had as basic sequence the clarification associated or not with the processes of pre-oxidation with KMNO IND.4, adsorption on PAC and post-chlorination. The r

2. Comportamento de sistemas pós-filtros adsorvedores na remoção de compostos orgânicos precursores e subprodutos da desinfecção. / Behavior of post-filter adsorbers in the removal of organic precursors and disinfection byproducts.
The main purpose of this work was to evaluate the performance of a Granular Activated Carbon (GAC) post-filter adsorbers in the removal of organic precursors and in the formation of disinfection byproducts, especially trihalomethanes (THM) in Alto da Boa Vista Water Treatment Plant (ABV WTP), which takes raw water from a highly eutrophized reservoirs.

3. Investigação da toxicidade, tratabilidade e formação de subprodutos tóxicos em efluentes clorados de lagoas de estabilização com e sem pós-tratamento. / Investigation of toxicity, treatability and toxic disinfection by-products formation in chlorinated stabilization ponds effluents with and without post-treatment.
The main difficulties that the stabilization ponds for sewage treatment systems face to meet the requirements imposed by CONAMA Resolution 357/2005 can highlight the high concentrations of ammonia nitrogen, phosphorus and fecal and total coliform. When the systems use receivers water bodies Class 2 or 3 generate the need for disinfection. Among the different
