Rediseño del Sistema de Tratamiento de Agua Potable para la parroquia Santiago de Calpi, cantón Riobamba.

Abstract

It was conducted a redesign study for the treatment system of drinking water from Santiago de Calpi, belonging to Riobamba canton; in order to provide its inhabitants a quality resource, enabling them to consume water without any risk to the health of the 98 people living in the region. Several samples of water were collected to be subjected to physical-chemical and microbiological characterization to be analyzed in different laboratories. The main parameters analyzed in situ were; pH, conductivity and temperature by checking the current state of water and taking as referential point the Technical Ecuadorian Regulations INEN 1108:2011 “Drinking Water”, in addition, laboratory scale test were established with the use of beakers, pipettes and appropriate techniques as the STANDARS METHODS. Having analyzed the 21 parameters characterized in this study; there was an alteration in phosphates with 1,45 mg/l, fluorides 2,01 mg/l, total coliform and fecal coliforms; more than 1UFC/100ml. The treatability was measured with Poly-Aluminum Chloride (PAC), but this method was not favourable, then, it was used zeolite previously activated with sodium chloride at 10% whose main function is the ionic exchange and the removal of phosphate was achieved in an 82,07%, fluoride 64,7%, also, microorganisms were removed in a 100% at a dosage of hypochlorite of calcium. It is concluded that the implementation of this redesign system is suitable for this region as this procedure complies the parameters established by the quality regulations. Hence, the use of zeolite for redesigned the system of drinking water is recommended.
