Resumo: | Allied to the saturation of conventional supply systems and the pollution of the main water sources, the recurrent situations of droughts and shortages have been affecting the availability of water in many regions of the country, once abundant in water, such as the SE. The present study is part of the development of the necessary knowledge on alternative sources for meeting society's basic water demands. In this case, we focus on the reuse of wastewater to supply industrial demands in the metropolitan region of Rio de Janeiro (RMRJ), since this reuse can contribute to reducing the pressure on already saturated springs and supply systems, saving drinking water for more noble uses. This study aimed to evaluate, in terms of quantity, the potential to meet the demand for reuse water for industrial and non-potable purposes, based on the supply of treated effluent from four sewage treatment plants (STPs Alegria, Penha, Pavuna, and Sarapuí) in RMRJ, whose characteristics, such as location and installed treatment capacity, favor them as potential suppliers of regenerated water. As potential consumers, we considered industries in the transformation sector located within a radius of 10 km from these treatment systems (STPs). The great potential for reuse in the scenarios studied was verified by comparing the installed capacity of secondary treatment systems and the production of regenerated water available at the listed STPs in relation to the industrial water demands of a total of 728 processing companies located in the respective coverage radii defined from each STP. Many of these industries can be served by more than one treatment plant and, in addition, the large availability of potential reuse water supply in relation to demand also indicates the feasibility of meeting the water supply for other sectors and industrial typologies. The most representative sectors for the four STPs, from the point of view of the number of companies, were 22-Rubber/Plastics (rubber artifacts and plastic packaging), 25-Metal products (metal structures, machining), and 28-Machinery and equipment manufacturing. From the viewpoint of flow, the most representative were 20-Chemicals (especially petrochemicals/polymer products) for all the STPs and 30-Manufacture of other transport equipment, except motor vehicles, only for the Alegria and Penha STPs. Although the four ETE's listed present good potential for supplying reuse water, the Penha STP deserved more emphasis for presenting the highest required flow rate due to the number of companies that can be served in its surroundings, besides already having a reuse water production system in operation since 2007. Despite having a lower available flow rate, in addition to a greater distance in relation to the center of mass of the demands related to the industrial blocks, the Sarapuí STP can also be considered as a priority for being the closest to the largest potential consumption of reuse water identified by the study, i.e., the companies of the REDUC complex. |

Quantitative evaluation of the potential for industrial reuse from the effluents of four sewage treatment plants in the Metropolitan Region of Rio de Janeiro, BrazilAvaliação quantitativa do potencial de reuso industrial a partir dos efluentes de quatro estações de tratamento de esgoto na Região Metropolitana do Rio de Janeiro, BrasilAllied to the saturation of conventional supply systems and the pollution of the main water sources, the recurrent situations of droughts and shortages have been affecting the availability of water in many regions of the country, once abundant in water, such as the SE.

O presente estudo insere-se no desenvolvimento do conhecimento necessário sobre fontes alternativas para atendimento das demandas básicas de água da sociedade. No presente caso, enfoca-se o reuso de águas servidas para suprimento de demandas industriais na região metropolitana do Rio de Janeiro (RMRJ), uma vez que esse reaproveitamento pode contribuir com a redução da pressão sobre mananciais e sistemas de abastecimento já saturados, resguardando a água potável para usos mais nobres. O objetivo deste trabalho é avaliar, em termos de quantidade, o potencial de atendimento a demandas por água de reuso para fins industriais e não potáveis, a partir da oferta de efluente tratado de quatro Estações de Tratamento de Esgotos (ETEs Alegria, Penha, Pavuna e Sarapuí) na RMRJ, cujas características, como localização e capacidade instalada de tratamento, as favorecem como potenciais fornecedores de águas regeneradas. Como potenciais consumidores, foram consideradas as indústrias do setor de transformação situadas no raio de 10 km a partir desses sistemas de tratamento (ETE’s). Constatou-se o grande potencial de reuso nos cenários estudados, comparando-se à capacidade instalada de sistemas de tratamento secundário e de produção de águas regeneradas disponíveis nas ETE’s elencadas em relação às demandas hídricas industriais de um total de 728 empresas de transformação, situadas nos respectivos raios de abrangência definidos a partir de cada ETE. Muitas dessas indústrias são passíveis de atendimento por mais de uma estação de tratamento e, além disso, a constatação da grande disponibilidade de oferta de água de reuso em potencial em relação à demanda indica ainda a viabilidade de atendimento do suprimento de água para outros setores e tipologias industriais. Os setores mais representativos do ponto de vista do número de empresas, para as quatro ETE’s, foram: 22-Borracha/Plástico (artefatos de borracha e embalagens de material plástico); 25-Produtos de metal (estruturas metálicas, usinagem); 28- Fabricação de máquinas e equipamentos. Sob a ótica da vazão, os mais representativos foram: 20-Produtos Químicos (especialmente, produtos petroquímicos/polímeros) para todas as ETEs e 30-Fabricação de outros equipamentos de transporte, exceto veículos automotores, somente para as ETEs Alegria e Penha. Apesar das quatro ETE’s elencadas apresentarem bom potencial para fornecimento de água de reuso, a ETE Penha mereceu maior destaque por apresentar a maior vazão requerida em função do número de empresas passíveis de atendimento no seu entorno, além de já dispor de um sistema de produção de água de reuso em operação desde 2007. Apesar de apresentar menor vazão disponível, além de maior distância em relação ao centro de massa das demandas referentes aos blocos de indústrias, a ETE Sarapuí pode ser também considerada como prioridade por ser a mais próxima do maior consumo em potencial de água de reuso identificado pelo estudo, i.g., as empresas do complexo da REDUC.ABEC2022-04-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontext/htmlapplication/pdfapplication/epub+ziptext/htmlapplication/pdfapplication/epub+ziphttps://www.revistasg.uff.br/sg/article/view/172710.20985/1980-5160.2021.v16n2.1727Sistemas & Gestão; v. 16 n. 2 (2021): AGOSTO 20211980-516010.20985/1980-5160.2021.v16n2reponame:Sistemas & Gestãoinstname:Universidade Federal Fluminense (UFF)instacron:UFFporenghttps://www.revistasg.uff.br/sg/article/view/1727/1467https://www.revistasg.uff.br/sg/article/view/1727/1493https://www.revistasg.uff.br/sg/article/view/1727/1468https://www.revistasg.uff.br/sg/article/view/1727/1469https://www.revistasg.uff.br/sg/article/view/1727/1494https://www.revistasg.uff.br/sg/article/view/1727/1470Copyright (c) 2021 Sistemas & Gestãohttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessObraczka, MarceloAlcântara Faria , Andre Soares da Silva Jr, Luis Carlos Akira Ohnuma Jr, Alfredo de Oliveira , Kelly Cabral Muricy, Bruno 2022-04-05T16:48:00Zoai:ojs.www.revistasg.uff.br:article/1727Revistahttps://www.revistasg.uff.br/sgPUBhttps://www.revistasg.uff.br/sg/oai||sg.revista@gmail.com|| periodicos@proppi.uff.br1980-51601980-5160opendoar:2022-04-05T16:48Sistemas & Gestão - Universidade Federal Fluminense (UFF)false |
