Secondary Disinfection Options

What is secondary disinfection?

Primary disinfection in water systems is the application of chemicals to kill or inactivate waterborne microorganisms, such as Legionella. Secondary disinfection is the maintenance of residual disinfectant in the water to prevent their regrowth.  The disinfectant achieves this by killing potentially harmful organisms as it moves through the water pipes. It is particularly important in buildings with vulnerable residents or customers, for example care homes and hospitals.

At Rock Compliance, we are always upfront and honest about any work we recommend or undertake. Our key aim is to minimise risk and eliminate the need for secondary disinfection. If you already use us as your water hygiene service provider, chances are that your systems do not need secondary disinfection. This is because we work with clients to minimise risk by resolving all non-conformances. We support our customers to simplify water systems, engineering out risk areas, so lessening the need for secondary disinfection. In this way, over time risk is reduced.

If your building is experiencing any of the issues below, don’t wait until the problem gets out of hand – contact us now to talk about secondary disinfection:

• Consecutive out-of-specification temperatures
• Loss of system primary control
• Consistent Legionella positives
• Current secondary disinfection system is ageing and needs to be replaced
• Current secondary disinfection system is unsafe
• Current secondary disinfection system is not working properly

Putting safety first

Ensuring the wellbeing of your staff, customers and building users is an absolute priority. Our solutions may not be the cheapest on the market, but they are the safest, providing an increased level of control that minimises risk and delivers compliance.

There are numerous ways water can be disinfected continuously, such as hypochlorous acid, chlorine dioxide, silver peroxide, hydrogen peroxide, copper/silver ions in liquid form. Each option has its benefits. Our engineers will determine the most efficient and technically correct one for your business and water system.

Whichever secondary system is installed, safety is the highest priority. This is particularly evident in the case of domestic water, where extra care needs to be taken in designing a dosing system to ensure harmful chemical cannot be overdosed, creating a chemical health concern. There are also regulations governing which chemicals can be added to potable water, with limiting concentrations.
