Proceso de ozonizado en la esterilización de agua envasada para el consumo humano.

Abstract

Purified water is potable water that undergoes rigorous purification processes to meet stricter quality standards. The human body, which is composed of 55% to 78% water, requires approximately Six liters ofwater daily, depending on various factors. The aim of this study is to evaluate whether the companies under analysis comply with the potable water quality standards set by the NT E INEN 2200 regulation, ensuring that the bottled water is safe for consumption. To measure quality, the Water Quality Indices (WQI) are used, which simplify data interpretation by consolidating the information into a single numerical value, allowing for temporal and spatial comparisons. Specific objectives include evaluating the effectiveness of treatment processes in removing bacteria such as mesophilic aerobes, Escherichia coli, and coliforms, as well as analyzing how bacteriological contamination relates to storage time. In the microbiological analysis, 24 water samples were collected from various stages of the process and inoculated into Compact Dry culture media to identify and quantify specific bacteria. The results provided key data on the microbiological quality of the water in the treatment and storage phases, enabling the assessment of the safety of bottled water for consumption.
