Resumen

La reutilización del agua es una necesidad mundial debido al crecimiento de la población, así como de la demanda económica. La falta de preocupación por las fuentes naturales de agua, el cambio climático y los hábitos de consumo terminan provocando una disminución del agua potable. Organismos mundiales dan cuenta de esta situación, la Organización Mundial de la Salud (OMS), en un informe, señala que casi 663 millones de personas en el mundo viven actualmente sin acceso al agua potable y la Organización de las Naciones Unidas (ONU), cita que para 2050 seis mil millones de personas se quedarán sin agua potable. Esta situación ha llevado a varios países a crear procesos alternativos de reutilización de agua con el objetivo de ahorrar agua potable para el uso exclusivo de las necesidades humanas. El objetivo de este trabajo fue realizar un estudio que muestre la reutilización de agua recolectada de la lluvia, sistemas de aire acondicionado y de fregaderos y duchas de un edificio comercial y dirigida a una planta de tratamiento de agua de reutilización (EDAR), para luego ser reutilizada como reposición de pérdida de agua en cuatro torres de enfriamiento. Se han presentado la estructura de las torres de enfriamiento y los procesos de la EDAR. Se han demostrado a partir de hojas de cálculo, los datos experimentales recolectados de la captación del agua de reúso, obtenidos en varias áreas del edificio estudiado, de enero a diciembre de 2021. El estudio teórico se complementó con el desarrollo de cálculos matemáticos y se concluyó que hubo una captación de agua de reúso de 10.828 m³/año y una pérdida de agua por las torres de 17.280 m³/año.
