SUMMARY:

Water security is one of humanity's greatest challenges, where water scarcity presents itself as a harsh global reality that worries states and nations on all continents. In this context, one of the most important actions to increase water security is the reuse of water in agriculture. In the Federal District, the regulation of water reuse in agriculture is being developed by ADASA and the Water Reuse Technical Chamber within the scope of the Federal District Environmental Council – CONAM/DF, constituting a relevant topic for basin committees hydrographic system of the DF, who seek to work on this topic in their socio-environmental activities. Aiming to contribute with solutions for water reuse in agriculture, this study simulates the implementation of sewage treatment alternatives Bioreactor with Membranes and Conventional Activated Sludge at ETE Brazlândia, with the main objective of comparing the viability of these alternatives for water reuse in agriculture. agriculture. The methodology adopted to analyze and compare the viability of these two alternatives considered an operational scenario of SES Brazlândia with the capacity to produce reused water and distribute it for irrigation in agriculture and multiple uses. To support the comparison between the treatment alternatives studied, the feasibility questions of the Hespanhol Matrix (1999) were answered, compliance with the reference legislation was verified and a multi-objective analysis was carried out to choose effluents for fertigation. When comparing the impacts between the alternatives, pros and cons of their viability were found. In addition to irrigation and fertigation in agriculture, the reused water produced by ETE Brazlândia could be used to recharge aquifers, reduce underground abstraction, combat forest fires in Flona, environmental preservation of the Rio Verde in Goiás, washing sewage collection networks of CAESB and dust control on local roads in Brazlândia. Given the possibilities, it is concluded that the implementation of water reuse in agriculture with effluents from ETE Brazlândia represents a potential for water availability with several socio-environmental and economic benefits. Regardless of the sewage treatment alternative chosen, it must be capable of removing nutrients and disinfecting the water to comply with the new effluent release permit from ETE Brazlândia. This improvement at the station will generate water security, environmental preservation and agricultural productivity for the Maranatha region, also enabling the recharge of aquifers for Lago do Descoberto. In the comparative analysis of the sewage treatment alternatives Bioreactor with Membranes and Conventional Activated Sludge, it was possible to conclude that both meet the requirements of the new effluent release grant, however the Conventional Activated Sludge alternative proved to be the most viable in relation to reuse. of water in agriculture, mainly due to lower costs, efficiency in nutrient removal and CAESB's vast experience in the operation and maintenance of this type of treatment.
