Legionella Control & Water Treatment
SureClear is a highly effective water treatment solution which is a truly credible alternative to traditional chlorine disinfection methods. It will totally remove biofilms whilst being non-corrosive at dose rates. Maintaining its efficacy at a wide range of temperatures and pH values, SureClear is odourless, colourless and tasteless; lending itself to many applications in the field of water treatment.
The Health and Safety Executive support the use of SureClear as a constant dose biocide in their official guidance document: HSG274 Pt 2 – The Control of Legionella Bacteria in Hot and Cold Water Systems.

The Legionella Problem
What is Legionella?
The bacterium Legionella pneumophila and related bacteria are common in natural water sources such as rivers, lakes and reservoirs, but usually in low numbers. Unfortunately, given the right conditions, Legionella bacteria can prosper in purpose built water systems in any type of premises.
When water contaminated with Legionella bacteria forms small droplets suspended in the air (aerosol or vapour), there is a very high risk of inhalation and the potential contraction of Legionnaires disease.
High Risk Legionella Areas
Cooling towers, evaporative condensers, spa pools/jacuzzis, hot and cold water systems. Systems that feature outlets like showers are particularly problematic, as water is turned to an aerosol and dispersed into the atmosphere.
Hospitals and nursing homes are higher risk as vulnerability to Legionnaires’ disease increases with age and pre-existing health issues.
The biofilm Problem
What is biofilm?
A biofilm is a group of micro-organisms in which cells stick to each other and adhere to a surface. Biofilms protect bacteria and provide a habitat that is the ideal environment for survival and replication. Additionally, the dispersal stage of the biofilm life cycle enables the spread and colonisation of additional surfaces. Biofilm removal is essential for clean water systems.
Biofilms can be found in
- Pipework
- Low flow areas
- Recirculated water
- Stored Water
- Water between 25°C and 45°C
- Deadlegs
The biofilm Lifecycle
Constant Dosing
SureClear constant dosing systems can be seamlessly fitted into any water system. Installation is simple and quick and the continuous dosing of SureClear, at very low required dose rates, ensures water is protected in an automated and controlled manner.
- 24/7 automated protection
- Proportional, metered dosing
- Low maintenance and cost effective
- Low chemical warning alerts
Manual Dosing
On smaller systems the manual dosing of SureClear is a simple and highly effective means of controlling water quality.
Using SureClear test strips the residual concentration is very easy to monitor and maintain. Full guidelines and instructions for use are available from your SureClear approved partner.
2.116 – Silver stabilised hydrogen peroxide
Silver stabilised hydrogen peroxide has a history of use in the control of legionella in water systems. A silver hydrogen peroxide solution is injected directly into the water system and if applied and maintained according to the manufacturers’ instructions, can be an effective means of control. As with any water treatment programme it should be validated to ensure it is effective in controlling legionella. Silver hydrogen peroxide should not be used in water systems supplying dialysis units.
