Diseño de un Sistema de Tratamiento para el agua de alimentación a los calderos en el parque Acuático los Elenes del cantón Guano.

Abstract

A design of a treatment system for the water that supplies the boilers in the Los Elenes Water Park from Guano Canton has been carried out. The objective is to offer quality water in order to improve and ensure efficiency in the production process if the steam which is used to warm up their semi Olympic swimming pool. By using the experimental method, five physical-chemical characterizations were done to the boiler supply water. An analysis in situ was performed by using the portable digital equipment, and the colorimetry and the spectrophotometry were done at the Technical Analysis Laboratory located at the Science Faculty, of the Escuela Superior Politécnica de Chimborazo (Higher Education Polytechnic School of Chimborazo). The analyses were established by the Standar Methods and the Process Handbook (HACH). Four parameters were outside the rules: pH 6.74, hardness 548.8 mg/L, bicarbonates 318.2 mg/L, and sulphates 636.6 mg/L. Based on this study, a softening system is applied obtaining the following results: pH 8.08, hardness  4 mg/L, bicarbonates 160 mg/L, and sulphates 188 mg/L. These specifications are within the ones established by the American Boiler Manufacturer's Association (ABMA), the American Society of Mechanical Engineering (ASME), the A Spanish Norm (UNE 9 075 92 3R /) and the Environmental Protection Agency (EPA/625/R-92/004); all these are established for the water quality in low preassure boilers. As a conclusion, the treatment system for the water that supplies the boilers will have a storage thank for raw water, two parallel cationic interchange stations, a reception tank for softened water, a tank for regenerating solution, and another for the solution of chemical product called ADL which will foster the optimal conditions at the end of the treatment. It is recommended that the Local Municipal Government in Guano (Gobierno Autónomo Descentralizado Municipal del Cantón Guano) implement the treatment system for the water that supplies the boilers in order to guarantee that the swimmers have the adequate temperate water.
