Performance evaluation of the sewage treatment system SANEBOX

Sewage treatment processes have been increasingly the target of research aimed at developing solutions that meet environmental standards at lower costs for society. The generation of sanitary sewage and its final release, without treatment or with inefficient treatment in sewage networks, lakes, rivers or oceans have aggravated the quality of water resources and put at risk the health of the population given water-delivery diseases. This article aimed to evaluate the results obtained by the Treatment System called SANEBOX, for the treatment of sanitary sewage, considering a period of two years of monitoring campaigns in it. Additionally, a comparison is made in terms of achieving environmental goals of this System with other conventional technologies that have usually been implemented in Brazil. The guiding parameters for this evaluation were Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Sedimentable Materials (SM), Total Suspension Solids (TSS), Vegetable or Animal Oils and Greases (OGv/a), Tensoactive Substances That React to Methylene Blue (MBAS), Ammoniacal Nitrogen (N-NH4+) and Phosphorus (P). The results obtained show that the SANEBOX System has similar performance and, in some parameters, much higher than the conventional Sewage Treatment System, either in terms of removal of pollutants, or in terms of occupied area, energy consumption and nuisance to neighborhoods by bad odors.
