Análise do tratamento e do destino final dos resíduos gerados nas estações de tratamento de água: estudo de caso no Sistema Italuís

Abstract

The work presents an analysis of the treatment and final destination of the waste generated in Water Supply Systems, having as study area the Italuís System, located in the cities of São Luís-MA and Rosário-MA. It is possible to emphasize the relevance of the theme for promoting the expansion of research on the subject and for evidencing improvements in the procedures adopted today. With the general objective to identify operational techniques, the negative and positive aspects of the treatments and final destinations of the waste in the ETS of the Italuís System. Thus, initially, a bibliographic review was carried out on the subject, including topics such as importance of water and supply systems, potability standards, unit processes, types of treatment and appropriate waste destination, focusing on sludge and water from ETAs. In addition to collecting conceptual data, technical visits and field surveys were made, so that it was possible to compare the reality of the Italuís System with the theory. With this, it was perceived that this system is compatible with the treatment of water, when compared with bibliographical studies. However, waste treatment does not exist, impacting the environment. However, it was verified that the concessionaire is seeking to reverse this situation, planning the implementation of a UTR. The treatment of waste generated in the ETAs is essential, since it contributes to minimize environmental, social and economic impacts. The Civil Engineering, being one of the responsible for the development, can and should help in order to collaborate, elaborating proposals for the mitigation of impacts in society, resulting from an ineffective waste treatment. Thus, the purpose of this paper was to explain the theme, to address the current situation of the Italuís System, located in São Luís- MA and Rosário-MA, and to suggest solutions for the negative aspects found
