Control microbiológico en etapas de purificación y producto terminado de el agua de bidones

Abstract

In the present study aimed to examine the microbiological quality of water in purification steps drums and as finished product, Cuenca Factory Bottling Company , also identified the sites of contamination establishing the possible causes of it. The present study is an observational, analytical, prospective cross-sectional. We performed a simple random sample of convenience, under this criterion 432 microbiological analyzes were performed over a period of six weeks between the months of April and June.

Microbiological quality indicators selected were total coliforms and aerobic mesophilic bacteria , the same that are mentioned in the technical standard criterion Ecuadorian giving a maximum permissible levels as the water is filled into the various stages of purification , molds and yeasts were selected on three criteria , is an indicator of the factory itself , and this purified water is used as raw material for the production of soft drinks which if standardized its presence , and finally molds and yeasts are indicators of organic matter decomposition. For analyzing the microbiological indicators was employed the method of Millipore ® membrane filter. The data were statistically analyzed using SPSS v.16.0 for Windows, with a significance level of P < 0.05.

The results showed low microbiological water quality drums. The stages for the coal purifier and reverse osmosis are the sites that have more pollution in the process.
