chlorination system control Applications
Chlorine Dioxide has been shown to be extremely effective in the control of legionella bacteria and the prevention of Legionnaires’ Disease and Feedwater’s patented Activ-ox® system is the easiest and safest way to treat drinking, domestic and cooling water with chlorine dioxide.

Whether you find yourself in a hotel bath room, cruise ship cabin, hospital, office building, industrial plant, greenhouse, car wash facility or your own hot tub, the combination of certain temperature levels, stagnant water and the presence of biofilm in water systems is a potential recipe for disaster: an outbreak of Legionnaires’ disease. An outbreak of Legionnaires’ disease is often the result of negligence, having legal repercussions for responsible parties. Because of its chemical and biocidal characteristics, chlorine dioxide is ideal for maintaining good standards of water hygiene. Chlorine dioxide has consistently been demonstrating to be the best molecule for eradicating the causative organism of Legionnaires’ disease.
As a selective oxidizing agent, chlorine dioxide possesses several chemical advantages when compared to the traditional use of chlorine in wastewater treatment. Chlorine dioxide does not hydrolyze in water, and thus it retains its biocidal activity over a broader range of pH. It is also non reactive with ammonia and most nitrogen-containing compounds, and thus effective at lower dose levels than chlorine. It also eliminates phenols, simple cyanides and sulfides by oxidation. Likewise it is effective at odor control and will oxidize sulfides. Chlorine dioxide is also effective at oxidizing iron and manganese compounds.

A brewery process presents one of the biggest challenges possible to a microbiological control program. Microorganisms are responsible for both the production and the degradation of the product. Microbial control is also critical for production and filling equipment. A brewing environment offers various applications where chlorine dioxide may be employed, like as terminal sanitizing rinse in the CIP systems or sanitizer for pasteurizers or filler head assemblies.
Most food processing facilities currently use a combination of different chemicals for all surface and machine disinfection. They periodically rotate the use of different sanitizers to prevent the harmful microorganisms from building a resistance to their killing properties. Unfortunately facilities are still experiencing pathogen outbreaks. Chlorine dioxide’s unique killing ability does not allow for the build up of resistance or mutation, and therefore eliminates the need for all of the other chemicals. Chlorine dioxide is effective for use in controlling microbiological growth in flume waters and other food processing water systems such as chill water systems and hydrocoolers.
