Secondary Disinfection
Our Environmental Hygiene Services (EHS) Group offers secondary disinfection of domestic water programs that can effectively utilize chlorine dioxide or copper-silver disinfection technology and address the most important issues you face on a daily basis.
Secondary Disinfection of water systems can mprove the quality of domestic water within facilities through minimizing the proliferation of harmful pathogens. We can offer you continuous disinfection services for domestic and other water systems as part of our managed response to Legionella issues. We also understand that continuous periodic testing and monitoring is essential to managing these dynamic systems and to evaluating and documenting preventative maintenance and corrective measures.
With increased liability concerns, many facilities are facing the need to develop effective prevention programs for waterborne pathogens, such as Legionella. Through development of a robust secondary disinfection program, we can help you:
- Reduce risks due to waterborne pathogens
- Increase life of water distribution systems through reduced hyperchlorination procedures
- Comply with all regulatory guidances (CDC, OSHA, JCAHO)
The objective of secondary disinfection is to maintain disinfection residual through the entire water system. The key to successful disinfection is to penetrate and remove biofilm. While there are many choices for secondary disinfection, research studies and practice are proving chlorine dioxide to be one of the safest and most effective methods currently available today.
We can assist you with your risk management plans by providing a turnkey solution that best meets your needs. We go well beyond the chemical solution through evaluating your entire water distribution system with our mechanical, operational and chemical approach, and then developing a customized solution that improves your overall efficiency and reduces your total cost of operation.
