Avaliação do Índice de Qualidade da Água Fornecida Pela Estação de Tratamento de Água de Rondonópolis - MT

Abstract

Water is a natural resource of extreme importance for human life and also for other existing ecosystems, in addition to providing some economic activities such as electricity generation, production in the fields, among others. In this way, it becomes a public good, which must be distributed with good quality to the population, that is, to meet the parameters present in Brazilian legislation. Therefore, the research in question aimed to monitor the quality of the water treated and distributed by the Rondonópolis-MT Water Treatment Station, thus highlighting turbidity as an important parameter for the analyses, but also taking into account all the others that must be analyzed according to Ordinance GM/MS No. 888, of May 4, 2021. To fulfill this proposed objective, it was necessary to carry out physical-chemical and microbiological analyzes, such as the aforementioned turbidity, color, pH, chlorine and microcystin, in the water that arrives at the WTS (Water Treatment Station) through the capture, called raw water, and in the treated water that leaves the WTS after going through all the treatment stages such as coagulation, flocculation, decantation, filtration and disinfection. The results presented showed that the parameters analyzed are within what is determined by the ordinance, even with the technical difficulties presented throughout the water treatment process. And in the end, it can be concluded that the raw water presents a great variation of turbidity, which ends up making the treatment difficult, but even so it was possible to obtain a good quality of water for distribution.
