    Eka® ClO₂ (chlorine dioxide) is the main bleaching agent used in modern environmentally compatible paper pulp manufacturing. Chlorine dioxide is the main component in ECF (Elemental Chlorine-Free) bleaching. Up to 99 percent of all chlorine dioxide produced worldwide is consumed by the Pulp Industry. Other common applications for chlorine dioxide include use as a broad-spectrum biocide and primary disinfectant for potable and cooling water. In water treatment, appropriate chlorine dioxide solution concentrations are metered directly from an on-site generator to the application point.
