Diseño de una planta de tratamiento de agua potable para la parroquia Guasaganda, la Mana - Cotopaxi

Abstract

The research is the design of a drinking water treatment plant for the parish Guasaganda, La Maná-Cotopaxi. It is intended to be the basis for managing the budget required for implementation. Within the methodology used is the inductive method for interviewing municipal authorities, flow measurement, the experimental method for physical-chemical and microbiological analysis, the methods are as follows: nephelometric (turbidity), EDTA titrimetric (total hardness), volumetric (chlorides), membrane filtration (total and fecal coliforms), float (flow). In addition, the most commonly used tools are: thermometer, nephelometer, pycnometer, spectrophotometer, microscope, balance, oven, test tubes, Petri dishes, balloons, tape measure, stopwatch. Sizing will require 0.0192 m3/s of water; The sand trap will treat: 0.76 m3, as retention time 39.51 s, it will retain fine sand of diameter 0.2 mm, as critical sedimentation velocity 0.03 m/s; Both slow sand filters will filter 0.0192 m3/s removing dissolved solids and organic matter; The storage tank will disinfect 69.12 m3 of water with calcium hypochlorite solution. The deductive method was used to make the conclusions of the research results. It was concluded that the Yanayacu River is qualitatively and quantitatively acceptable as a source of supply. Comparing the results of the water before and after potabilization, the plant's performance is feasible because it fully complies with the NTE INEN 1108 standard for drinking water. It is recommended that the municipal authorities protect the water supply source to prevent contamination and plant native trees along its banks to maintain its flow.
