Ultrasonic technology for sustainable control of biofilm, legionella and fouling.

Find out how USAF can help fight this effectively.

Reliable cooling and process water systems, with reduced chemical use.

Why industrial water systems become contaminated
Cooling and process water systems are vulnerable to:

  • Biofilm formation
  • Legionella bacteria
  • Larvae of mussels, oysters, and barnacles

This contamination arises from stagnant or slow-flowing water within the system, or from water intake from rivers or the sea.

 

The consequences for your installation

  • Health risks from legionella
  • Blockages and reduced cooling capacity
  • Higher energy and water consumption
  • Increased maintenance and downtime
  • Accelerated corrosion (especially pitting corrosion)

 

Why traditional methods fall short

Many installations still rely on chlorine injection or other chemical treatments to control biological growth. However, these are not always fully effective because:

  • Biofilm forms a protective layer that chemicals cannot fully penetrate.
  • Larvae attach themselves under the biofilm.
  • Bacteria in biofilm are up to 1,000× less sensitive to chemicals.
  • Higher chemical doses increase environmental impact and costs, and may also violate regulations.

The Benefits of USAF for Industrial cooling and process water.

  • Effective against biofilm – targets the root cause of contamination
  • Physical control – bacteria and larvae are directly disrupted
  • Minimal chemical use – ultrasound enhances existing water treatment
  • Low maintenance – easy to integrate into existing systems
  • Sustainable and Reliable – keeps the system clean without high chemical doses

USAF™: One sustainable solution for multiple challenges.

Pitting corrosion
✔ Less biofilm → reduced local corrosion

 

Fouling in cooling water
✔ Larvae cannot develop → no fouling

 

Legionella
✔ Biofilm is broken down → bacteria lose their habitat

 

Industrial Applications

  • Cooling towers
  • Heat exchangers
  • Intake channels
  • Process water circuits
  • Storage tanks
  • Condensers

USAF™ works as a catalyst to boost your current water treatment.

USAF can be applied alongside traditional water treatment methods such as chlorine, biocides, or filtration. It does not replace these systems but enhances their effectiveness and drastically reduces the amount of chemicals needed, because:

  • Biofilm is broken down, allowing chemicals to penetrate more deeply and effectively
  • Required dosages are much lower to achieve the same results
  • Filters and strainers become less prone to fouling
  • The overall water treatment process becomes more stable and predictable

In short, USAF acts as a catalyst, drastically reducing chemical use. This saves costs and helps comply with environmental and safety regulations.
