Resumo: According to the Alliance to Save Energy, between 2 % and 3 % of the total electric energy consumed in the world is used for water pumping in supply systems, with the consumption reduction potential through energy efficiency and conservation measures being estimated at 25 %. In Brazil, the water supply sector corresponds to 2.6 % of the total energy consumed in the country, with pumping systems being responsible for over 90 % of the total energy consumption. It is extremely common to find supersized facilities with pump motor sets operating outside their ideal points, with it being a common practice to perform flow and pressure control through the installation of valves. The use of reducing valves inserts unnecessary pressure drops into the hydraulic system, increasing energy consumption. The objective of this work is to present an energy balance of a study sector of the Autonomous Water and Sewage Service (AWSS) of a municipality in the south of Minas Gerais, Brazil, aiming to elucidate the electric energy consumption of the system and where the reduction in such consumption may occur. For this, we measured data such as the efficiency of the pump motor sets, calculated performance indicators and water loss indices, and applied the energy balance adapted. This work presents an application of a water-energy balance with adaptations to a Brazilian water supply system, under the perspective of the energy efficiency in lift station pump motor sets.

En Brasil, el sector de abastecimiento de agua corresponde al 2,6% del total de energía consumida en el país, siendo los sistemas de bombeo responsables de más del 90% del consumo total de energía. Es muy común encontrar instalaciones de gran tamaño con conjuntos de motores de bomba operando fuera de sus puntos ideales, siendo una práctica común realizar el control de flujo y presión mediante la instalación de válvulas. El uso de válvulas reductoras introduce caídas de presión innecesarias en el sistema hidráulico, lo que aumenta el consumo de energía. El objetivo de este trabajo es presentar un balance energético de un sector de estudio del Servicio Autónomo de Agua y Alcantarillado (SAAA) de un municipio del sur de Minas Gerais, Brasil, con el objetivo de dilucidar el consumo de energía eléctrica del sistema y donde puede producirse una reducción de dicho consumo. Para ello, medimos datos como la eficiencia de los grupos motobomba, calculamos indicadores de rendimiento e índices de pérdida de agua, y aplicamos el balance energético adaptado. Este trabajo presenta una aplicación de un balance agua-energía con adaptaciones a un sistema de abastecimiento de agua brasileño, bajo la perspectiva de la eficiencia energética en grupos motobomba de estaciones elevadoras.De acordo com a Aliança para Economia de Energia, entre 2% e 3% do total da energia elétrica consumida no mundo é destinada ao bombeamento de água nos sistemas de abastecimento, sendo o potencial de redução do consumo por meio de medidas de eficiência e conservação energética estimado em 25%. No Brasil, o setor de abastecimento de água corresponde a 2,6% do total de energia consumida no país, sendo os sistemas de bombeamento responsáveis ​​por mais de 90% do consumo total de energia. É extremamente comum encontrar instalações superdimensionadas com conjuntos de motobombas operando fora de seus pontos ideais, sendo prática comum realizar o controle de vazão e pressão através da instalação de válvulas. O uso de válvulas redutoras insere quedas de pressão desnecessárias no sistema hidráulico, aumentando o consumo de energia. O objetivo deste trabalho é apresentar um balanço energético de um setor de estudos do Serviço Autônomo de Água e Esgoto (SAAE) de um município do sul de Minas Gerais, Brasil, visando elucidar o consumo de energia elétrica do sistema e onde o redução desse consumo pode ocorrer. Para isso, medimos dados como a eficiência dos conjuntos de motobombas, calculamos indicadores de desempenho e índices de perdas de água, e aplicamos o balanço energético adaptado. Este trabalho apresenta a aplicação de um balanço hídrico-energético com adaptações a um sistema de abastecimento de água brasileiro, sob a perspectiva da eficiência energética em conjuntos motobombas de estação elevatória.Research, Society and Development2021-08-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1903910.33448/rsd-v10i10.19039Research, Society and Development; Vol. 10 No. 10; e380101019039Research, Society and Development; Vol. 10 Núm. 10; e380101019039Research, Society and Development; v. 10 n. 10; e3801010190392525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/19039/16937Copyright (c) 2021 Matheus Gonçalves Silqueira; Fernando das Graças Braga da Silva; Alex Takeo Yasumura Lima Silva; Matheus David Guimarães Barbedohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSilqueira, Matheus Gonçalves Silva, Fernando das Graças Braga da Silva, Alex Takeo Yasumura Lima Barbedo, Matheus David Guimarães 2021-10-02T21:49:16Zoai:ojs.pkp.sfu.ca:article/19039Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:39:01.856167Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
