Comparison of Sanitary Sewage Treatment Systems: Nereda in Relation to the Stabilization Pond Treatment System in the Legal Amazon

The difficulty that great nations often suffer in relation to the lack of efficient basic sanitation for their entire population has, over the years, become a concern of global proportions. Although the rate of service with sewage collection corresponds to a high percentage of active water connections in suitable areas in Porto Nacional in the state of Tocantins, (City and therefore, state belonging to the legal Amazon) when we look at the total scenario of the Amazon Legal, only a small percentage of people living in these areas are served with sewage collection and treatment. Knowing then that the percentage of a given population served with collection and an effective sewage treatment system is directly related to the quality of life and health of its population, this work set out to present the innovative Dutch sewage treatment system that emerged on the NEREDA patent, compared to the conventional sewage treatment system used in the city of Porto Nacional - TO. Finally, the objective of this study was to present this Dutch technology based on public domain data presented by Brazilian bodies and entities, as well as other studies already carried out and the data of the company that owns the patent. Although still little known in the world, this technology presented great potential both qualitatively and economically because it presented a greater amount of treated sewage per second with quality equal to or greater than other methods, in addition to low implementation value due to the possibility of use most of the existing treatment plants.
