Avaliação da eficiência da dupla filtração para remoção de turbidez em uma estação de tratamento de água

Abstract

The quality of water bodies is closely tied to the uses of the basin in which they are inserted. Currently, with the disordered growth of urban centers, aquatic ecosystems suffer great pressure which eventually deteriorate the quality of its waters. This aspect is of paramount importance to assess the quality of the raw water that surge to the treatment plants, in order to produce drinking water from the removal or reduction of certain constituents of the water, natural conditions that characterize it as unclean or unfit for human consumption. Given this, it is appropriate to the prior knowledge of raw water and its features to guide the selection of treatment processes, with the basic premise of raw water quality, as well as the desired quality for treated water. The method of water treatment may pose a barrier to the transmission of diseases. The type of treatment can vary from a simple to a more complex treatment disinfection, depending on the source used. In this context, we highlight the importance of filtration in water treatment as the main stage held in an ETA, which constitutes a fundamental health barrier further disinfection supplementing the conventional treatment cycle. At the end of this work, it might be inferred that the overall efficiency of color removal was 93.6 and turbidity parameter, 97.6, whereas dry spells and rainy, which reiterates the good functioning of the ETA even when the watchman Ordinance that precedes the current one.
