Diseño de sistema de tratamiento de agua potable para la comunidad de Bellavista cantón Colta.

Abstract

A system of potable water to the community of Bellavista in Colta town, with the goal of providing quality water for the inhabitants of this area was designed. For the devolopment of research samples of water shed in this community were taken for physical-chemical and microbiological characterization using standardized for drinking and wastewater and Water Analysis Manual methods, with the results two parameters they are out of the permissible limits given by the Ecuadorian Technical Standard INEN 1108:2011 Drinking Water. Requirements Second Revision such as: iron with a value of 0.48 mg/l fluoride with a value of 2.5 mg/l; wáter well as the organoleptic characteristics presents unpleasant odor and taste. Therefore it was necessary to select a treatment that allows us to reduce the above values, aeration process with which it was posible to reduce the concentration of iron up to 0,03 mg/l flouride to 1,17 mg/l was simulated; finally the water was chlorinated to ensure that reaches free of fecal coliforms each of the homes. Therefore the treatment system consists of a collection tank from where wáter is carried ingo a tower aeration 2 m tall and subsequently passed to a chlorination system. With this process, a removal of 53 % fluorine and 94% iron is achieved; he also managed to improve the physical appearance of the wáter and its organoleptics characteristics. It is concluded that the proposed tratment is appropiate to achieve set parameters that are outside the norm quoted in the Standard NTE INEN 1108:2011 Drinking Water. Requirements. Second Revision; and provide quality water to the residents of the community of Bellavista. The Decentralized Autonomous Municipal Government is advised of Colta applying desing system for drinking water tratment.
