Análise bibliométrica da produção científica sobre patologias observadas em estações de tratamento de água

Abstract

This work is a narrative bibliographic review on the survey of the main pathological manifestations found in Water Treatment Plants (WTP) and their origins, causes and mechanisms. The aqueous environment in which the reinforced concrete structures are inserted in the treatment units is a facilitator for the action of aggressive agents, intensifying their action mechanisms and their deleterious effects, providing the appearance of pathological manifestations. After analysis, discussion and theoretical basis provided by scientific research on the subject, the visualization of the degree of criticality of the manifestations discussed was performed, through the use of the GUT prioritization matrix, in order to relate the anomalies with their priority for resolution. Thus, it was observed that the structural elements that are affected by corrosion of the reinforcement should be prioritized as to the degree of risk and intervention. It was also possible to see the relevance of treating pathological manifestations such as surface wear by erosion, leaching, cracking and carbonation. The extreme importance of corrective maintenance is evident, while the need for effective compliance with preventive maintenance is even more highlighted.
