  • Publication number: 20230137919
    Abstract: Unwanted material in water, such as Legionella and scale, may be treated using a combination of technologies. Components of each technology may be controlled using a databus, such as an Internet-of-things (IoT) databus. An additional advantage of the treatment technologies is an increase in the efficiency of heat transfer components, such as cooling towers, and a related reduction in carbon footprint.
