Aplicação do processo eletrolítico no tratamento de água e efluentes.

Abstract

In several regions of Brazil, basic sanitation services are still precarious, exposing people to the risk of contact with contaminated water because of the pollutants contained in domestic sewage and industrial effluents. The appropriate treatment for each type of effluent is a function of the pollutant load and the presence of contaminants. The electrolytic process presents itself as an alternative and complementary technique for the treatment of effluents and has been researched over the last decades. In this way, the study aimed to verify the application of the electrolytic process in the treatment of water and effluents. In order to reach the main objective, a bibliographic survey of the application of this process in the treatment of effluents and water was carried out. With the information found in the literature it was possible to construct tables presenting the main advantages and disadvantages of the process as well as the efficiency obtained by the researchers. It was verified that the process was very efficient in the removal of pollutants and nutrients. However, it still needs more detailed studies to better understand its mechanisms.
