Abstract
Aguas Antofagasta S.A. es una empresa de servicios sanitarios ubicada en la región de Antofagasta, los productos y servicios que suministra son la producción y distribución de agua potable. Una de las principales comunas que abastece la empresa es Antofagasta, un 85% de la producción es abastecida por la Planta Desaladora Norte (PDN) y el porcentaje restante por la Planta de Filtros Salar del Carmen (PFSC). Debido a la sequía que afecta a la región, es que se quiere asegurar el suministro de la población con un 100% vía desalación, dejando así a la PFSC como respaldo cuando la PDN deba disminuir caudal, esperando poder trabajar la PFSC a un caudal de 20 [L/s].
El objetivo general de este trabajo es determinar la factibilidad técnica de adaptación de la Planta de Filtros Salar del Carmen para su operación a un caudal de 20 [L/s], y como objetivos específicos se tiene: demostrar la viabilidad operacional de los coaguladores y filtros de la planta a un caudal de 20 [L/s], identificar las variables que afectan la calidad del agua y como influyen al realizar la disminución de caudal, plantear un método de puesta en marcha de coaguladores fuera de servicio y finalmente, estimar la dosificación de productos químicos a utilizar.
La metodología utilizada para demostrar la viabilidad tanto de coaguladores como filtros a bajo caudal fue realizar cambios de caudal en estos, por otro lado, para identificar las variables que afectan la calidad del agua del agua, se observó el comportamiento de los coaguladores al trabajar distintas velocidades del viento, y filtros al realizar movimientos en las válvulas, drenajes y lavado de estos, por otro lado, un método de puesta en marcha en coaguladores fue realizar el vaciado de este para posteriormente llenar de agua fresca, para finalmente estimar la dosificación de productos químicos mediante un análisis de datos.
Aguas Antofagasta S.A. is a sanitary services company located in the Antofagasta region, where the products and services that provides are the production and distribution of drinking water. One of the main communes that the company supplies is Antofagasta, where 85% of the production is supplied by the North Desalination Plant (PDN) and the remaining percentage by the Salar del Carmen Filter Plant (PFSC). Because of the drought that affects the region and the responsibility that Aguas Antofagasta has with the people, it is wanted to assure the supply of the population with 100% water from desalination and leaving the PFSC as backup when the PDN must reduce flow, hoping the PFSC to work at a flow rate of 20 [L/s]. The main objective of this work is to determine the technical feasibility of adapting the Salar del Carmen Filter Plant for its operation at a flow rate of 20 [L/s]. And the specific objectives are: demonstrate the operational viability of coagulators and filters at a flow rate of 20 [L/s], identify the variables that affect the water quality and how they influence when the flow rate is reduced, propose a method for the setting up of coagulators out of service and finally, estimate the dosage of chemical products to be used. The methodology used to demonstrate the viability of coagulators and filters at low flow was to make flow changes in them. On the other hand, to identify the variables that affect the water quality of the water, the behavior of the coagulators was observed when working different wind speeds, and filters when making movements in the valves, drains in coagulators and washing them, furthermore, a start-up method in coagulators was to empty it and then fill it with fresh water, to finally estimate the doing of chemicals through data analysis.
