Diseño de un Equipo de Potabilización de Agua para el Consumo Diario de 500 Personas en la Ciudad de Yopal Operado Mediante un Sistema Mixto de Energía Solar, Térmica y Fotovoltaica

Abstract

This document presents the methodology for designing a solar-powered water purification system to supply a population of 500 people in Yopal-Casanare. The amount of potable water needed per person daily was determined, and the required water quality was investigated according to the Colombian Technical Standard and Decree 1575. Additionally, the water quality of the Cravo Sur River was evaluated and found to be suitable for human consumption, although it needed treatment to be potable.

For the equipment design, requirements were established for each stage of the process, including collection, filtration, purification, and storage. Different equipment was selected for each stage, including a centrifugal pump for collection, activated carbon for filtration, a UV light lamp for purification, and a polyethylene tank for storage.

It was determined that the photovoltaic system required a power of 4.7 kW 5.5 to operate the pump and UV lamp, and three modules with a nominal power inverter of 1000 kW were chosen to meet this demand. Energy losses were also evaluated, and four solar panels were installed to meet the daily energy demand.

The project has an approximate cost of $80,000,000 COP, which includes material costs, installation, transportation, and maintenance from the first year of production. The annual energy savings were calculated, and the return on investment time was projected.
