Evaluación fisicoquímica y microbiológica del agua potable de la planta potabilizadora del cantón Chordeleg

Abstract

Water is an indispensable resource for life; for this reason, your treatment system must be evaluated and controlled periodically, to ensure their quality for human consumption. The main objective of the present study was to assess through a physico-chemical and microbiological quality and system water treatment which is done on the water treatment plant of Chordeleg canton. We conducted a non-experimental study, field, descriptive and not slitting. For physical-chemical analysis 176 samples were evaluated in 8 weeks, doing 1 sampling day. In each sampling was carried out 11 samples which correspond: 2 sample of raw water, 2 pre-filtrada water samples, 6 samples of water filtered and 1sample of treated water to performing a total of 22 samples a week, which determined the physico-chemical parameters: temperature, total dissolved solids, turbidity and colour, pH, hardness, alkalinity, iron, sulphate, nitrites, nitrates and residual free chlorine; microbiological parameters: total and faecal coliforms. The results obtained in tests, using statistical analysis showed that physicochemical parameters conform to the standard INEN 1108-2014, while microbiological parameters established for total coliforms found outside the established range, whereas fecal coliforms are within the range established by the INEN 1108-2014 standard and total coliforms outside established by WHO (absence) .
