| Abstract |
The objective of this work was to verify the economic viability of using sanitary sewage, treated with different levels of efficiency, for central pivot fertigation in cotton and soybean crops. The study was developed through the simulation and comparison of two sanitary sewage treatment projects to be installed in the city of Correntina (BA). For feasibility calculations, the AmazonSaf spreadsheet was used. Two scenarios were proposed for the treatment of sewage for subsequent fertigation: scenario A (pre-treatment followed by anaerobic lagoon) and scenario B (pre-treatment followed by Australian pond system and polishing with wetland ecotechnology). It was observed that the total costs were higher in scenario B, due to the increase in investment with wetland treatment. The direct increase was 0.82%, with a payback period of 8.7 years. There is economic viability in reusing the treated sanitary effluent from the municipality of Correntina for irrigation of cotton and soy, regardless of the treatment system to be adopted, although complementing the process with the installation of the wetland system is advantageous from an economic point of view, environmental and social. |
