Diseño de un Sistema de Tratamiento para la potabilización del agua en la parroquia Valparaíso del cantón Guano provincia de Chimborazo.

Abstract

The purpose of the following research is to design a treatment system for the purification water process at Valparaiso Parish located in Guano Canton, Chimborazo Province. The characterisation of raw water was made through physicochemical and microbiological analysis by using espectrophotometric, volumetric and instrumental procedures. To collect the initial samples and for the development of jar test, the label precautions were adopted obtaining an appropriate dosage of lime. After that they were tested at Laboratory of Technical of Faculty of ESPOCH. Six physicochemical parameters such as: water hardness, calcium, magnesium, alkalinity, bicarbonates and dissolved solids that are aver the allowed limits according to Drinking Quality for Human Consumption INEN – 1108 2011 were identified. On the other hand it made a study to get a right treatment method so that, the final results were achieved: Water hardness: 80.0 mg / l, calcium: 16 mg / l, magnesium: 15.6 mg / l, alkalinity: 200 mg / l, bicarbonates: 204 mg / l, and dissolved solids: 380.0 mg/ l. The design of the treatment plant contains a rectangular landfill mixer tank whose length is 0.662 m, width: 0.236 m, height 0.50 m; plate settler, length 2.33 m, width 2.40 m, depth: 3 m; quick sand filter, length: 1.86 m, Width: 1.86 m, area: 3.46 m2; chlorine mixing tank, height: 3.21 m, volume: 9.63 m3. Finally it recommends to GAD. Valparaiso Parish to apply the purposed treatment system which will ensure better quality water for human consumption.
