Legionella Treatment with HydroFLOW®
HydroFLOW® supports the control of Legionella pneumophila by disrupting biofilm formation, treating limescale, and improving water system hygiene. It helps reduce microbial risk, minimises chemical use, and supports compliance with water safety standards in high-risk environments.
Managing Legionella Risk with HydroFLOW®
Legionella bacteria thrive in warm water systems where biofilm and scale provide shelter and nutrients. These conditions are common in cooling towers, hot water systems, spas, and HVAC setups. Controlling Legionella requires effective management of water hygiene, including the reduction of biofilm, temperature control, and minimising stagnant conditions.
HydroFLOW® offers a chemical-free, non-invasive solution that supports Legionella reduction strategies by tackling the root causes: biofilm and limescale. It complements existing Legionella control measures such as thermal disinfection, filtration, and chemical dosing – helping reduce the microbial load and improve safety.

HydroFLOW® Solutions for Legionella Risk Reduction: Safety, Hygiene, and Compliance

Disrupts Biofilm – Legionella’s Safe Harbour
Biofilm acts as a protective layer for Legionella, shielding it from heat and disinfectants. HydroFLOW® reduces biofilm formation by disrupting bacterial adhesion to surfaces, leaving fewer hiding spots for microbial growth.
Inhibits biofilm development in pipes, tanks, and heat exchangers
Improves effectiveness of thermal and chemical disinfection
Supports long-term microbiological control
Enhances compliance with Legionella control standards
Treats Limescale to Minimise Legionella Habitats
Limescale provides a rough, porous surface where biofilm can establish. HydroFLOW® treats scale by altering crystallisation behaviour, keeping minerals in suspension and minimising deposits that encourage bacterial colonisation.
Treats scale in calorifiers, boilers, and pipework
Eliminates surfaces where Legionella can thrive
Maintains system cleanliness and heat transfer efficiency
Reduces the need for aggressive chemical descaling


Improves Water Flow & Reduces Stagnation
Legionella proliferates in stagnant or low-flow areas. HydroFLOW® improves system performance by keeping internal surfaces cleaner, which helps maintain consistent flow and circulation throughout the system.
Reduces dead legs caused by scaling or blockages
Maintains optimal circulation in hot and cold water systems
Lowers the risk of microbial hotspots
Supports more consistent water temperatures
Reduces Chemical Dependency & Environmental Impact
HydroFLOW® works alongside conventional biocide and disinfectant regimes, allowing many systems to lower dosing requirements while maintaining microbiological control.
Supports reduction of biocide usage over time
Improves safety for staff and occupants by reducing chemical exposure
Minimises discharge of treated water with residual chemicals
Supports sustainable and eco-friendly water management


Reduces Maintenance & Inspection Burden
HydroFLOW® helps maintain clean internal surfaces, reducing the frequency of manual cleaning, disinfection, and remedial actions following failed Legionella tests.
Decreases the need for regular flushing and descaling
Reduces downtime and compliance-related interventions
Lowers risk during Legionella audits and water safety reviews
Supports risk reduction in accordance with HSE’s ACOP L8 and HSG274
