In Brazil, more than half of the sewage generated by the population is treated,
however, this is a reality only because the basic sanitation service, which includes
the provision of sanitary sewage services, is concentrated in the most populous
regions of the country and in its capitals , inland cities located mainly in the North and
Midwest of the country do not have access to this type of service. The objective of
this work was the implementation of a pioneering project of a Constructed Flooded
System with Vertical Flow (SAC-EV) as an alternative tool for decentralized sewage
treatment, the project was carried out at the Institute of Education, Agriculture and
Environment - IEAA/UFAM , located in the municipality of Humaitá, state of
Amazonas. Four collections were carried out to analyze the parameters of pH, Total
Solids, Turbidity, Biochemical Oxygen Demand, Dissolved Oxygen, Total
Phosphorus, Total Nitrogen, Thermotolerant Coliforms. Among the eight parameters
analyzed and compared directly with the standards established by CONAMA
resolutions 357 and 430, the SAC-EV was able to meet five of them, highlighting the
BOD results where it was removing about 49.36% of organic matter and Nitrogen
Total where about 69.15% of the pollutant was degraded within the system, proving
to be a likely path to be followed, however further studies are needed to adapt the
system to all the particularities of the region.
