Optimización de la unidad de floculación y calidad, microbiológica y físo-química del agua del sistema de abastecimiento de la parroquia Sinincay

Abstract

Water is a valuable and essential resource for life, thus improving access to drinking water can provide tangible benefits to health and development of society. The aim of this study was to evaluate the microbiological and physico-chemical quality of Sinincay drinking water distribution network, which some previous reports of changes in color and turbidity that it had. This study was performed among the months of July and August 2013, which was divided into three stages. First were evaluated samples taken from five different sectors of the parish through determinations of color, turbidity, pH, electrical conductivity, hardness, total and fecal coliforms. Subsequently, was developed an experiment in which the dose of aluminum sulphate to the water purification process was optimized and finally were evaluated the same determinations after the experiment. All data were entered and processed in the SPSS v.11.5 package. As indicated earlier reports, turbidity and color parameters were the most affected, besides the chlorine concentration and pH. Apparently, this depends mainly on the distance between the sampling point and the water treatment plant.

The optimal dose of aluminum sulfate in this study was 55 mg /l. The introduction of the new dose improved significantly the quality of drinking water, especially for the parameters color and turbidity.
