Caracterización y propuesta de tratamiento de aguas crudas para su comercialización como agua embotellada

Abstract

The purpose of this research project is to evaluate the quality of raw water from the San Andrés natural spring located in the Hermano Miguel parish, by means of a physico-chemical and microbiological study in the samples collected from both the water body and the water system. income of the COMPROPUR DEL ASUTRO S.A company. For the study were taken 64 samples, considering the criteria for sample collection of the Ecuadorian standard NTE INEN 2169: 2013 and 2176: 2013, on Monday and Wednesday of each week respectively. The physical-chemical parameters that have been considered for quality assessment in raw water were: temperature, pH, turbidity, SDT, conductivity, color, total hardness, total alkalinity, nitrites, nitrates, sulphates, iron and cadmium; and the microbiological parameters were: total coliforms, fecal coliforms and mesophilic aerobes. The results obtained from the study revealed that criteria such as color, turbidity, nitrites, total coliforms, faecal coliforms and mesophilic aerobes do not comply with the requirements of the RTE INEN 055: 2011 and the NTE INEN 2200: 2008 norms. From the results, the necessary treatment proposal was made to condition the raw water and a DPO was prepared for it, which includes processes such as: coagulation and flocculation, sedimentation; filtration with sand, disinfection by chlorination; storage, filtration with activated carbon, finally disinfection by ozonation.
