Chlorine Dioxide

Our  ‘Oxichem’  Chlorine dioxide (ClO2) is a safe, compact and reliable chlorine dioxide generator.

It can be supplied in component form or as a plug-and-play fully automated skid mounted system. We offer 24/7 continuous residual monitoring to ensure safe and acurate dosing at all times.

Chlorine Dioxide is a highly effective, environmentally-friendly microbicide.  It is a selective oxidant that eliminates both planktonic and sessile bacteria, disinfects surfaces, and destroys biofilms very rapidly.  ClO2 is a stable, dissolved gas that is a strong bactericide and virucide at concentrations as low as 0.1 ppm.  With minimal contact time, it is highly effective against many pathogenic organisms such as Legionella, amoebal cysts, Giardia cysts, E. Coli, and Crypto-sporidium.  ClO2 destroys biofilms so bacterial regrowth is significantly impeded.

Chlorine Dioxide has many applications including:

Cooling Towers and Loops:

ClO2 controls algae, planktonic bacteria, biofilm and scale for maximum efficiency of heat exchangers and ancillary equipment.  ClO2 is more stable than other oxidizing biocides and compatible with most water treatment chemistry.  This “selective oxidation” makes ClO2 ideal for systems with corrosion problems.

Potable Water:

ClO2 is approved for both pretreatment and final disinfection of drinking water.  In pre-treatment, it effectively removes iron and manganese and promotes flocculation.  It also removes taste and odor components as well as halogenated disinfectant byproduct precursors e.g. trihalomethanes (THM’s).  In post-treatment, it provides a lasting residual throughout the distribution system.  ClO2 is also ideal for small water supplies, cisterns, and hospital water systems.  ClO2 does not form THM’s or haloacetic acids (HAA’s).

Food and Beverage:

ClO2 provides excellent microbiological control in flume waters, packaging operations and process disinfection.  Thus, it is ideal for the washing of fruits and vegetables (FDA approved) as well as bottling and brewery applications.  ClO2 does not react with most “organics” in flume water, which makes it a very effective disinfectant.  It also neutralizes foul smelling secondary and tertiary amines formed in the meat packing industry.

Waste Treatment and Odor Control:

ClO2 safely oxidizes phenols, cyanides, aldehydes, amines, and mercaptains, reduced sulphur compounds and some pesticides.  It is useful in both waste treatment and scrubber systems.

"Chlorine dioxide is a very safe and potent biocide. It is effective over a wide pH range in both hard and soft water and does not react with most other water treatment chemicals."

Halpin & Hayward supply, install, commission and offer service contracts on all our equipment.

We also supply and fit all necessary Parts & spares, and other consumables. Our Dublin warehouse holds stock of our most commonly used products and what we do not have in stock can be quickly sourced.
