Chlorine Dioxide in Water Treatment
Activ-Ox® is Feedwater's patented Chlorine Dioxide generation process. It is simpler, safer and more effective than most other ways of producing chlorine dioxide and is equally suitable for building services, food and beverage and industrial applications. It can be used to treat anywhere from a few litres to 1,000s m3 of water per day and has also been incorporated into a unique foam disinfection and cleaning process.
Chlorine Dioxide is a powerful biocide and disinfectant for the effective control of a wide range of harmful bacteria and other problematic microbes such as legionella pneumophila, the bacteria which cause Legionnaires' Disease.
The Journal of Applied Microbiology reports that: "Chlorine dioxide...was identified as the most efficient [continuous treatment] for controlling L. pneumophila in a domestic water system.
How does Activ-Ox produce Chlorine Dioxide?
The Activ-Ox process uses 2 pre-cursor chemicals in much the same way a conventional Chlorine Dioxide generator does, but with some very important differences. The patented Activ-Ox chemistry releases ClO2 instantaneously, whereas a conventional Chlorine Dioxide generator or stabilised Chlorine Dioxide dosing system can take several hours to give its maximum yield of ClO2.
The chlorine dioxide yield of the Activ-Ox process is very high, converting around 95% of the pre-cursor chemical to ClO2. This is higher than other processes and much higher than some so-called stabilised Chlorine Dioxide systems, which not only give a low yield but take a long time to do it.
Another critical difference between Activ-Ox and other chlorine dioxide systems is that it doesn’t need a strong acid to work. Activ-8, the matching pre-cursor to Activ-Ox is a special blend of food / drinking water approved weak acids, which is classified as non-hazardous. The patented Activ-Ox chemistry is so different from the way conventional Chlorine Dioxide generators work - you could even activate it with Coca Cola!

How is Activ-Ox dosed?
Because, unlike other processes for producing Chlorine Dioxide, Activ-Ox releases ClO2 instantaneously and completely, we have been able to develop a much simpler dosing system than a conventional Chlorine Dioxide generator or stabilised Chlorine Dioxide system. No gas is released, and there is no need for a reaction vessel storing dangerous concentrated mixtures, instead the CLO2 is produced directly in solution in a special “T” fitting which is installed in water stream to be treated.
How is the Chlorine Dioxide level controlled?
The Activ-Ox dosage is typically controlled by a signal from a water meter in the make-up line to the system being treated. This provides precise, direct fail-safe proportional control over the dosage of ClO2 and is inherently much simpler and safer than most Chlorine Dioxide generators. The Activ-Ox dosing system can be programmed to deliver the required chlorine dioxide level and will add ClO2 at that rate based on the water flow.
Since water supplies and water distribution systems have a chlorine dioxide demand, particularly if they have an established biofilm, each Activ-Ox dosing system is supplied with a simple test kit to enable the residual ClO2 to be tested at strategic locations and the dosage level to be adjusted to establish and maintain the required free chlorine dioxide residual throughout the system being treated.
Whilst water meter controlled dosage is the most common arrangement we can also supply systems with direct chlorine dioxide monitoring and timer controlled dosage.
