Diseño e implementación de un sistema de captación para el tratamiento de agua lluvia mediante ósmosis inversa para los Laboratorios de Biotecnología y Bromatología - ESPOCH.

Abstract

The design and implementation of a system of rain water collection by reverse osmosis was used for the use in the Biochemistry and Bromatology laboratories of the Faculty of Sciences of the Polytechnic Higher School of Chimborazo and to provide type II water in the laboratories for the Execution of student practices. The research was based on a bibliographical review of works carried out in relation to the subject matter, in the physical, chemical and microbiological characterization of rainwater and type II water obtained by the treatment of reverse osmosis - deionizer, in engineering calculations, and In the construction of the system. For the design of the rainwater harvesting system, rainfall values ​​were taken, intensity belonging to the study area, determining the design flow rate used in the calculation of rainwater harvesting. The system has: a collection area in the ceilings of the laboratories, the system of conduction through PVC pipe, storage in a reserve tank of 550 L suitable to supply the type II water consumption required for student practices and Distribution of rainwater after reverse osmosis treatment - deionizer. With the treatment given to rainwater it was possible to establish that it was possible to reduce physical and microbiological parameters from 98 to 99%, obtaining a conductivity (1 μ Siemens / cm, Chlorine (3 mg / L) and Microbiological (10/100 ML), parameters established in ASTM D1193-99 for water type II analytical grade required for use in laboratories. With the application of the rainwater collection system will provide water of excellent quality and quantity to the student sector of the Higher Polytechnic School of Chimborazo to carry out the practices in the laboratories of Bromatology and Biochemistry. It is recommended to perform an adequate, periodic maintenance to the system and to the equipment implemented.
