Microbial and physico-chemical quality of MIROSI

Description
Bottled water consumption is increasing more and more, so it is important to be monitored the quality of bottled water. The current paper contains data on the microbial and physicochemical quality of natural mineral water, produced by the MIROSI water industry. The standard water testing methods were used to assess the microbiological and physicochemical quality of bottled water. During the sampling period, 645 samples were taken at four sampling points, before and after UV treatment. Quality is monitored by determining microbiological and physico-chemical parameters such as: total colifoms, total microflora at 37oC, pH, temperature, conductivity, total hardness, calcium, magnesium, chloride and KMnO4. The results showed that the mean concentrations of physicochemical parameters were within the reference values of ISO standards for these parameters. Microbiological analyses indicated that water samples taken from water tank and bottled water containers 10 L, before UV treatment, had mean values of total microflora at 37oC 3.2 – 3.9 CFU/ml and mean values for total coliforms 0 CFU/ml. It is therefore recommended to regularly monitor bottled water quality, before and after production to fulfil the basic water quality standards EN ISO/IEC 17025:2018.
