Biofilm Sensor for Cooling Towers - Brochure

In industrial cooling towers, biofilm growth can cause serious problems, both contributing to the deterioration of materials and, most important, increasing the risk of harmful microbiological contaminations (e.g. Legionella). For these reasons, large amounts of chemical substances (biocides) are used to limit microbiological growth in such systems. The manager of this cooling tower planned to automatically dose chlorine continuously (24/7) in the water; later on, he decided to install an ALVIM probe in the plant, to check the effectiveness of the treatment.
