Diseño, simulación e implementación de un sistema de bombeo para agua procedente de una planta de tratamiento de aguas residuales en la comunidad de San Vicente de Lacas

Abstract

In this research work, the design, simulation and implementation of a pumping system for the San Vicente de Lacas community is developed. The mission is to help the community to improve its irrigation water supply for agricultural development, in order to maintain and increase the community's economy. Starting from the study of the physicochemical and microbiological properties of the water obtained from the treatment plant that is suitable for irrigation, the required flow is also analyzed, indicating a value greater than 5 L/s. The pipe that is presented in the design was selected maintaining the working pressure and it was estimated that all the pipe is made of PVC material, due to the low cost and easy acquisition in the local market. After this, the analysis of primary losses, secondary losses and pumping height was carried out, to guarantee the correct operation and water supply. With this, the operating point is determined with the characteristic curve of the pump and the resistive curve of the system, resulting in a flow operating point of 6 L/s and a height of 33,74 m. After this, a simulation is carried out in the EPANET software to corroborate the calculations, which, compared to the calculated data, is presented in a permissible error, then through the ALLIEVI software, it is allowed to observe a behavior of the fluid within the system to analyze if there is the presence of a transitory flow, resulting in that this phenomenon does not occur in this system. The implementation of an automated control system is recommended, for which a flow chart was formulated with the necessary electronic components and which are taken to a "Ladder" programming language.
