The Molecule

Chlorine Dioxide is the ultimate biocide. As a dissolved gas in solution, it can destroy and remove biofilm, eliminate both sessile and planktonic bacteria, and prevent their regrowth without interfering with most water treatment chemistry. As a weak oxidizer, it can destroy odors, clarify, and precipitate iron and manganese from contaminated water sources. As the ultimate biocide, it can eradicate Legionella and other harmful bacteria living and growing in water systems. These properties make Chlorine Dioxide the ideal biocide for most water treatment applications.

The System

The CLO2IX® Portable Systems are the only mobile Chlorine Dioxide production systems. The rugged cart frame is built to take the abuse of going up and down stairs, over hoses, and through wet environments. In addition, the CLO2IX® PTG Series Systems utilize replaceable ion exchange cartridges, so there is no need to regenerate the system. Whether the application is emergency service or yearly cooling tower cleaning, the system consistently produces Chlorine Dioxide by utilizing the company's patented Chlorine Dioxide production method.

The Process

The CLO2IX® PTG System is based on pure water technology found routinely in the pharmaceutical and semiconductor industries where purity and safety are not optional. Instead of the traditional way of making Chlorine Dioxide by either mixing concentrated chemicals or through electrochemistry, which produces dangerous byproducts, the CLO2IX® method combines ion exchange and catalytic technologies to ensure consistent product quality in a rugged industrial piece of equipment.



How the System Works

Inlet Potable Water
A potable water source is required for the system.

Sodium Chlorite
A 25% NaClO2 solution is diluted with potable water, such that the resulting concentration of NaClO2 is 1,250 mg/l.

Chlorous Acid
The dilute NaClO2 flows through the ion exchange cartridge, where the NaClO2 is converted to HClO2 through the exchange of the Na+ in solution for the H+ on the cation resin.

Chlorine Dioxide
The HClO2 is converted to dilute ClO2 in the catalyst cartridge. The concentration of solution is a safe 700 mg/l.

When the catalyst cartridges are changed, water is flushed through the system to drain.
