Chlorine Dioxide

The Chlorine Dioxide molecule is relatively small, volatile, and very energetic – a free radical. It is stable in dilute solution, but unstable in concentrated form. Thus,chlorine dioxide is almost always used as a dissolved gas in water in concentrations that range from 50 to 5,000 ppm. Because transportation of concentrated chlorine dioxide is not safe, chlorine dioxide is almost always produced on site.

ClO2 is a highly effective biocide that kills bacteria, viruses, algae, fungi and protozoa.

Used properly, ClO2 has little or no effect on human, animal or fish cells and is safe to use.

ClO2 is unsurpassed in its disinfection capabilities throughout water systems, also in “dead end” areas. For this reason, ClO2 is often used to disinfect chilled water, municipal water systems and hot and cold water systems in hospitals and health care facilities, where bacteria such as Legionella can prove to be stubbornly resistant to other biocides, chlorine in particular.

Furthermore, chlorine dioxide does not affect taste or form toxic chloramines or haloforms (THM). This is a characteristic that makes ClO2 ideal for flavor sensitive applications such as wine and brewing.

The Process

The single precursor eChem Chlorine Dioxide generation process electrolytically converts Sodium Chlorite to Chlorine Dioxide gas in the patented OxiMax CDE cell. This gas is then stripped from the solution in the patented vClone and then dissolved in water to be stored in the Solution Tank at a level of up to 2,000 ppm.

Recirculation of solutions optimises efficiency and minimises power consumption to allow outstanding performance from a compact machine.

The process is safe, reliable and is controlled by a microprocessor, which continuously monitors the performance of the machine, makes the appropriate decisions and displays the status via the LEDs and on an LCD screen.
