Tratamento de água para abastecimento público: estudo de caso do departamento de água e esgoto de Coruripe (DAESC)

Abstract

Water is an important environmental resource and is closely linked to the social and economic development of a population, providing quality water means promoting and expanding urbanization and industrialization processes, as well as the growth of the local environment. The objective of this work was to analyze the operation of the Coruripe Department of Water and Sewage, the methods employed and to propose improvements to the system, aiming at increasing the efficiency of treatment and quality water for the population. Knowing that organic matter can be found in groundwater and that humic substances are some of its constituents, through the disinfection process, the reaction between humic substances and chlorine used can generate disinfection byproducts: Trihalomethanes, harmful agents to human health. The use of clarifying organic matter or activated carbon removal methods are alternatives to prevent or minimize the emergence of disinfection by-products. In addition, there is also a need to perform analyzes with the raw water captured so that treatment can be performed according to the characteristics of the water captured.
