Un método para proporcionar agua de enfriamiento de alta calidad microbiológica para un proceso industrial donde el proceso industrial comprende una planta industrial , comprendiendo el método: a. Recolectar agua de entrada desde una fuente (11) de agua ; b. Almacenar el agua de entrada en un contenedor (12), donde el contenedor tiene un fondo (13) capaz de ser limpiado por unos medios (22) de succión móvil; donde el contenedor es un cuerpo artificial grande de agua con un volumen de al menos 10.000 m3 y en donde el área superficial del contenedor (12) está en el rango de 50 a 30 .000 m2 por MW de enfriamiento requerido por el proceso industrial ; c. activar los siguientes procesos a través de unos medios de coordinación: i. en períodos de 7 días, agregando un agente desinfectante al agua en el contenedor: 1. Para una temperatura del agua en el contenedor de hasta, e incluyendo, 35°C, mantener un ORP del agua del contenedor sobre 500 mV durante un período mínimo de 1 hora por cada oC de temperatura del agua en el contenedor;

A system for treating water and using the treated water for the cooling of industrial processes is disclosed. The water is treated and stored in a large container or artificial lagoon (12), has high clarity and high microbiological quality. A system of the invention generally includes a containing means, such as a large container or artificial lagoon (12), provided with a feeding line (11) for inlet water, a coordination means (10), a chemical application means (18), a mobile suction means (22), a propelling means for moving the mobile suction means (23), a filtration means (20) for filtering the cooling water containing settled particles, a collecting line (19) between the mobile suction and the filtration means, a return line (21) to return filtered water from the filtration means to the containing means (12), an inlet line (1) from the containing means to the industrial process (9) and a return water line (2) from the industrial process (9) to the containing means (12). The coordination means (10) monitors and controls the processes in order to adjust water quality parameters within specified limits. The large container or artificial lagoon (12) can act as a heat sink, absorbing waste heat from the industrial process (9), thus creating thermal energy reservoirs in a sustainable manner, which can be later used for other purposes. The system can be used in any industrial cooling system with any type of water available, including fresh water, brackish water, and seawater.
