10 Apr Chlorine Dioxide Disinfection
Chlorine Dioxide (CLO2) based biological control systems are used in a variety of industries as a primary method for control of micro-organisms in water systems, from controlling bacteria in food processing to Legionella in cooling towers.
Its use in the treatment of water has been driven by an increased awareness of biological related health issues.
It is commonly used as a ‘dispersive’ treatment which means the chlorine dioxide is dosed into the water system and travels around the entire water system. This ensure a ‘residual’ level of CLO2 which can continue to kill bacteria in all areas of the system that it reaches and not just at the point of use. This helps to explain why chlorine dioxide is so effective.
ClO2 in its pure form, exists at room temperature as a gas and dissolves in water. The EMEC LOTUS range of Chlorine Dioxide Generators are designed so there is no requirement to handle this as a gas, but instead two liquid ‘precursor’ chemicals, Hydrochloric Acid (HCl) and Sodium Chlorite (NaCl02), react together to form the chlorine dioxide required.
The EMEC LOTUS systems can dose proportional to the circulating water or based on the measurement set point. EMEC LOTUS does not store the chlorine dioxide therefore there is no chlorine dioxide gas or concentrated solutions outside of the process application.
