"Desenvolvimento e padronização de protocolos de amostragem e análises físicas, químicas e bacteriológicas para estação de tratamento de águas

Abstract

Water is an essential natural resource for the survival of animals and plants, in addition to being part of countless human activities. Basic sanitation includes water supply, sewage collection and treatment services, urban cleaning, garbage collection and disposal, and rainwater drainage and management. Drinking water is strongly related to quality of life, public health and human development. Drinking water is water that is properly treated for human consumption, free from any type of microorganisms, suspended solids and toxic substances that cause contamination and disease. The supply of drinking water to the population requires, in general, treatment by a Water Treatment Plant (WTP), following the laws and technical standards in force, which regulate the quality standards of this water. This Course Completion Work addresses the issues of drinking water quality, legislation involved, and stages of water treatment, with a focus on improving activities in a WTP, located in Candiota-RS city. As main activities developed in this work are the knowledge of the operational routines of Dario Lassance’s WTP, the bibliographic research to the fundamental concepts and the current legislation of the water quality, and the elaboration of protocols for the performance of the water sampling, and of physical analyzes chemical and bacteriological tests carried out at WTP. The protocols formulated were intended to standardize the operation of collections and analyzes, in addition to following exactly the procedures indicated in the legislation and technical standards, according to ANVISA's Practical Manuals. 13 protocols and 3 standardized documents were drawn up for recording analysis results. All the documents prepared were presented and passed on to the administration sector of Dario Lassance’s WTP, in order to assist, facilitate and standardize the daily activities of its operation. It is expected that the knowledge acquired over the course of Chemical Engineering, applied here, will benefit the functioning of WTP and the society of Candiota, with the supply of drinking water of good quality.
