Dantek provides effective solutions for maintaining clean and safe water systems in entertainment and recreational facilities, including leisure centres and theme parks. Controlling Legionella in water systems is crucial to protect the health and well-being of visitors, staff, and operators. While temperature control is often the primary method, situations may arise where it is not feasible to control the risk with this method. In these situations, chlorine dioxide is a highly effective means of control that can be used to make water systems safe to use once again.
The Importance of Chlorine Dioxide Dosage
Chlorine dioxide dosage has proven to be an extremely effective tool in combating Legionella growth and ensuring water system safety. It eliminates Legionella bacteria, prevents their multiplication, and minimizes the risk of Legionnaires’ disease transmission. In cases where temperature control is challenging or not an option, chlorine dioxide dosage provides a practical and effective solution. In addition to its bactericidal properties, chlorine dioxide also possesses the capability to remove biofilm, a slimy layer formed by microorganisms that can attach to the inner surfaces of pipes, tanks, and other components within water systems. It provides a protective environment for Legionella bacteria to thrive and multiply, making biofilm control crucial in Legionella management.
Important Considerations for Legionella Control
Before installing a CLO2 unit, it is crucial to conduct a comprehensive review of the water risk assessment and the existing control regime. This review helps identify potential areas of concern and determines the appropriate dosage requirements for effective Legionella control. In cases where control is lost, certain initial steps should be taken, such as reviewing the number and locations of samples taken and assessing the percentage of failures in the sampling process. It is particularly important to focus on water systems where the treatment regime, including factors like temperature and disinfectant concentrations, is not consistently achieving the desired control levels. Alongside the thorough review of the system and treatment regimes, frequent testing should be carried out, ideally on a weekly basis, to provide early warning signs of control loss. Once the system is successfully brought back under control, as evidenced by monitoring results, it is advisable to reassess the frequency of testing.
Implementing Regular Legionella Testing
While chlorine dioxide dosage is an effective control measure, it should be complemented with regular Legionella testing. Legionella testing serves as an interim safety check until a viable control solution, such as chlorine dioxide dosage, is fully implemented. Regular testing helps monitor the effectiveness of the control measures and ensures the ongoing safety of the water system.
Proven Effectiveness in Legionella Control
Chlorine dioxide dosage has established itself as a highly effective solution for controlling Legionella in domestic water systems. Its implementation significantly reduces the risk of Legionella contamination, providing reassurance to facility owners and operators. The benefits of using chlorine dioxide dosage for Legionella control are numerous:
- Reduced Chemical Handling Issues: Chlorine dioxide is derived from relatively safe precursor chemicals, such as CDA (Chlorine Dioxide Activator) and CDB (Chlorine Dioxide Base). These are weak solutions of acid and salt, making them easy to handle and minimizing chemical handling concerns.
- Enhanced Oxidative Power: Chlorine dioxide possesses approximately 2.6 times the oxidative power of chlorine. This increased potency enables it to effectively kill Legionella bacteria within drinking water limits.
- Biofilm Removal: The ability to remove biofilm, a slimy layer that provides a habitat for Legionella bacteria. By eliminating biofilm, chlorine dioxide disrupts the conditions conducive to Legionella growth, further enhancing the efficacy of Legionella control measures.
- On-Site Testing and Safety Verification: Easy to test for on-site. This enables swift verification of safety through a simple on-site test, providing timely feedback on the effectiveness of Legionella control efforts.
- Compliance with Standards: The chemicals used for generation, CDA and CDB, comply with BS EN 1278 standards. This compliance ensures that effective levels of chlorine dioxide can be continuously dosed into drinking water supplies, meeting the necessary regulatory requirements.
- Low Ongoing Chemical Costs: CDA and CDB efficiently treat a large volume of water, resulting in cost-effective Legionella control. This helps minimize ongoing chemical expenses associated with maintaining water system safety.
- High-Quality Equipment Installation: Dantek provides chlorine dioxide solutions and installs top-of-the-range equipment to ensure the generation of the purest chlorine dioxide. This minimizes the production of by-products like chlorite and chlorate, further enhancing the safety and quality of the treated water.
By leveraging these benefits, chlorine dioxide dosage proves to be a reliable and efficient approach to Legionella control, offering peace of mind to those responsible for the safety of water systems.
Flexible Application
Dosage can be applied in various water system configurations, making it adaptable to different entertainment and recreational settings. Whether it is a small leisure centre or a large theme park, chlorine dioxide dosage can be tailored to suit specific requirements.
Continuous Protection
Once the dosage is implemented, it provides continuous protection against Legionella growth. By regularly dosing the water system with chlorine dioxide, the risk of Legionella multiplication is effectively minimized, ensuring a safer water supply for visitors and staff.
System Overview and Installation
Dantek specialises in the installation of CLO2 units specifically designed to address problematic systems that have tested positive for Legionella. Our units are meticulously engineered to generate chlorine dioxide automatically, providing a reliable and uninterrupted disinfection process.
