Diseño e Implementación de un Sistema Automatizado para la Dosificación de Cloro en el Tratamiento de Agua Potable en la Comunidad San Vicente de Lacas.

Abstract

An automatic System of Chorine Dosage has been implemented for the San Vicente de Lacas-Riobamba Community where there was not where was not any chlorine provision, to secure permanently the water potability. Moreover a hydraulic system evaluation guaranteeing the design period as to caudal and piping dimensions is carried out. Before selecting and efficient disinfection device replacing the original obsolete system a monitoring of the residual chlorine levels was carried out in the sector network for a period of two months based on the INEN 1108 Norm and the support of the Technical Department of EMAPAR, while the water conduction piping measurements are according to the CO 10.7-602 Norm of the Ecuadorian Code for design of Sanitary Works Construction. With the results it is evident that the most reliable alternative is the chlorine process automation. This is a system capable of constantly analyzing the free chlorine levels with amperometric sensors and based on these values providing the necessary disinfectant quantity through a valve which responds to a controller. The Control System of the close link of proportional function is the best option which fits in with understanding the behavior required by a chlorine water distribution network. The conjunct mechanical part works with a pump which propels the disinfectant solution line where the gas chlorine is injected through suction generated in a Venturi; the gas feeding comes from the 68-kg cylinders liked by a selecting circuit valve. On the other hand the hydraulic evaluation shows the material selection and piping dimension for the different conduction parts. With the implementation of this system independence of an operator is reached of dosage and the free chlorine levels in the distribution network between 1.1 ppm and 0.5 ppm, values accepted by the INEN 1108 Norm. It is recommended to train the personnel handling the equipment within the community who will understand the preventive health with water quality.
