Liquitech’s copper silver ionization (CSI) is a nonchemical water treatment technology regarded as the most clinically effective prevention and remediation solution for Legionella. During this treatment, ions are systematically introduced into the water using a byproduct-free and corrosion-free method to rid plumbing infrastructure of Legionella bacteria and other waterborne pathogens. CSI is an electrolysis process, which introduces positively charged copper and silver ions into the water supply. The positive ions bind to the negative cell walls of bacteria, causing the protein in the cell wall to break down, effectively eliminating the bacteria. Liquitech. www.liquitech.com
