Nanobubble Systems

Nanobubbles, tiny gas bubbles smaller than 200 nanometers, possess unique chemical and physical properties that make them highly effective for controlling Legionella and reducing the risk of Legionnaires’ disease. As an independent Legionella consultant with engineering expertise, Legionella Control Systems provides a range of solutions for waterborne pathogen management. Below is an overview of how nanobubbles combat Legionella:

Enhanced Oxidation

• Nanobubbles are often enriched with oxygen or ozone, both powerful oxidants.
• When they collapse, they release hydroxyl radicals and reactive oxygen species (ROS).
• These radicals target waterborne pathogens by:
  • Oxidizing bacterial cell membranes.
  • Disrupting critical cellular processes, resulting in bacterial elimination.

Biofilm Disruption and Surface Cleaning

• Legionella frequently resides in biofilms, slimy microbial layers that cling to water system surfaces.
• Nanobubbles lower surface tension, enabling penetration and breakdown of biofilms.
• Gas-infused bubbles also prevent biofilm regrowth by continuously supplying reactive oxygen to affected areas.

Improved Mixing and Coverage

• Neutrally buoyant nanobubbles remain suspended in water, avoiding rapid rising to the surface.
• This ensures even distribution of gases like ozone or oxygen throughout water systems, treating pipes, tanks, and reservoirs uniformly.
• Comprehensive coverage targets pathogen colonies in difficult-to-access areas.

Prolonged Effectiveness

• Due to their small size, nanobubbles linger in water longer than larger bubbles, resisting quick rising or bursting.
• This longevity supports sustained disinfection within water systems.

Eco-Friendly Solution

• Nanobubble technology minimizes reliance on chemical disinfectants like chlorine, which can generate harmful byproducts.
• Ozone nanobubbles break down into oxygen post-treatment, leaving no toxic residues.

Secondary Disinfection Applications

• Cooling Towers: Nanobubbles inhibit biofilm formation and lower bacterial levels in cooling tower water systems.
• Potable Water Systems: By oxidizing contaminants and breaking down biofilms, nanobubbles enhance water quality and prevent bacterial proliferation.
• Wastewater Treatment: Nanobubbles reduce microbial contamination in treated wastewater, improving overall safety.
