Chlorine Dioxide Treatment

Chlorine Dioxide, an established and proven biocide with advantages over other biocides including oxidising biocides such as Chlorine and Bromine.

Chlorine Dioxide is DWI (Drinking Water Inspectorate) approved for use in hot and cold water systems, is tested by BISRIA for Legionella Pneumophila efficacy and is accepted as part of the HSE ACoP L8 for the treatment of Legionnaires Disease.

Chlorine Dioxide is normally dosed at a concentration between 0.3 – 0.5 ppm for drinking water (DWI maximum is 0.5 ppm as total oxidant), at this level there is virtually no detection as far as taste and odour. However in other process applications the dose rate may be higher, particularly where the excess can be removed as part of the process.

Chlorine Dioxide is stable in water and does not dissociate. This makes it much more suitable for use at higher pH levels than both Chlorine and Bromine. It does not react with impurities that may be present in the water to form THM’s (Tri Halo Methane’s).

Chlorine Dioxide is normally produced ‘in situ’ by the mixing of two chemical precursors, Sodium Chlorite and Hydrochloric acid, in the correct concentrations and volumes to generate the gas in a safe and controlled manner.

Typical Applications include: drinking water, process water, pulp and paper bleaching.
