    Determinación de la tendencia corrosiva e incrustante del agua potable distribuida en la ciudad de Azogues
    (2017) Pauta Novillo, Alex Damián; Quezada Sisalima, Diego Armando; García Ávila, Fausto Fernando
    Corrosion control in drinking water distribution networks is an important aspect and the effects of corrosion may not be evident. Without a monitoring record there are significant issues in relation to public health and economic aspects. There are water quality parameters that are related to the chemical stability of water, such as: pH, temperature, Total Dissolved Solids (SDT), alkalinity, calcium hardness, sulfates and chloride in mg / l. These parameters were used to determine the corrosive tendency or fouling of drinking water in the potable water supply network in the city of Azogues. The Langelier Saturation Index (IL), Ryznar Stability Index (IR) and Larson-Skold Index (ILS) were calculated using the above parameters in order to evaluate the chemical stability of the potable water samples that were taken during six month samplings. The experimental results reduced during the six months (from July to December), of the three incidents of chemical stability indicated: according to the Index of Langelier there is strong corrosion; Ryznar index indicates very severe corrosion. While according to the Larson-Skold Index there is significant corrosion, the parameters that significantly affect the indexes are for: Langelier index, pH and hardness as Calcium in mg / l, for Ryznar Index, pH, and hardness as calcium in mg / l, and for the Index Of Larson-Skold we have sulfates; The present study demonstrated the application of water stability indexes, classifying it as corrosive.
