Chlorine Dioxide Dosing Units
Chlorine Dioxide Dosing Units are now part of Comfort Services Group Limited Water Treatment Services.
Comfort Services Group Limited are proud to announce that we are now covered by Legionella Control Association (LCA) for Plant & Equipment as part of our services provided in the water treatment industry.
Comfort Services Group Limited can provide you with the full package including equipment and installation, chemical supply, service breakdown along with a full monitoring regime with monthly serving and plant monitoring visits. The units are installed and maintained by our team of specially trained engineers, site service specialists and technical experts.
The installation and fittings are all WRAS approved: Since 2008, the Water Regulations Advisory Scheme (WRAS) has been committed to safeguarding public health through the prevention of public water supply contamination, as well as ensuring efficient water usage. Any water fitting that comes into contact with public mains water supply must comply with the 'Water Supply (Water Fittings) Regulations' which can be illustrated through WRAS approval. For more information on WRAS and WRAS approvals follow https://www.wras.co.uk.
Chlorine Dioxide Dosing Systems use established technology in order to deliver a controlled amount of chlorine dioxide disinfectant to the water system to be treated. This powerful water disinfectant is effective at killing waterborne pathogens, Legionella, virus and bacteria including Giardia, Oocysts and Cryptosporidium.
Comfort Services Group Limited design, supply and install bespoke dosing control units to aid application along with usual disinfection measures that help the control of Legionella and other bacteria. The use of chlorine dioxide is permitted in accordance with the HSE Guide L8 and leaves no aftertaste in the water which is an added benefit with this product.
Use and application
Chlorine dioxide (ClO2)
Chlorine Dioxide is a powerful antioxidant commonly used as a disinfectant in water. This agent disinfects regardless of pH and normal ambient temperatures. It has a very good sustained-release effect and remains active in the pipes for many hours and days. Chlorine dioxide can be used to treat entire water systems to combat Legionella and Chlorine dioxide is proven to reliably break down biofilms in pipework, cold water storage tanks, hot water storage cylinders / calorifers and domestic services distribution systems.
Chlorine dioxide is produced at the point of application by mixing stabilised chlorine donor liquid and an acid activator.
The use of chlorine dioxide in the treatment of water for building services has grown significantly in recent years. This is a result of several factors, e.g. increased awareness of biological related health issues, the need to conserve energy and the increasing quality and simplicity of use of chlorine dioxide systems. In use chlorine dioxide is termed a ‘dispersive’ treatment, this means that the chlorine dioxide is dosed into the water system and travels around the entire circuit providing a ‘residual’ level of treatment. This is very important as it means that the applied chlorine dioxide can continue to kill bacteria in all areas of the system that it reaches and not just at the point of use and this helps to explain why chlorine dioxide is so effective.
There are more benefits to the use of Chlorine Dioxide and its treatment technology. In addition to the control of Legionella, it kills a wide range of other bacteria, E.Coli, Coliforms, Pseudomonas, Cryptosporidium, Giardia Cysts, Algae and Amoebae. It is approved for use in drinking water by the Drinking Water Inspectorate (DWI) (<0.5ppm Total Oxidant) and is very simple to test for and monitor.
Chlorine dioxide has been shown to be more effective than chlorine in the control of Legionella bacteria and pseudomonas species. Due to the way it works, chlorine dioxide will never lose its efficiency, which makes it an ideal residual biocide. Chlorine dioxide is also far less corrosive than chlorine, meaning that systems last longer and risks of internal system degradation are significantly reduced.
Environmental safety is a key advantage of chlorine dioxide when comparing with alternative biocides. Unlike chlorine, ClO2 will react to form mainly inorganic disinfection by products, the predominant species being chlorite. Chlorite will subsequently reduce to form harmless chloride. Modern generation systems are able to monitor and adjust the dose rate to ensure that environmental limits are not breached.
