ESCOBAR, María Camila; TOVAR, Luis Felipe    ROMERO CUELLAR, Jonathan. DESIGN OF AN EXPERT SYSTEM FOR REUSING TREATED WASTEWATER. []. , 26, 2, pp.21-34. ISSN 0124-8170.  https://doi.org/10.18359/rcin.1827.

This work describes an expert system that uses fuzzy logic to back decision support systems (DSS) up for a municipal treated wastewater reuse project. The hydroinformatic tool calculates water reuse potential. This tool uses two parameters: a drought index and BOD5 wastewater treatment rate. The DSS was validated in the municipal wastewater treatment plant (MWTP) of Nátaga, Huila, Colombia. The methodology used water balance, water quality analysis, and expert surveys. The fuzzy logic toolbox of Matlab (MathWorks) was used to implement the fuzzy inference system (FIS). The results showed a wastewater treatment rate of 88.7% and drought index of 28.5, which means a high-medium drought index. Therefore, the expert system suggests water reuse of 92.2%. The output of systems is classified as a reliable and justified water reuse. It is concluded that the expert system is suitable to identify alternative sources of water resources. Finally, the decision support tools can help governments to implement policies that integrate management of water resources.
