Operation USAF™
How do USAF™ cavitating ultrasonic transmitters work?
USAF transmitters continuously transmit high-frequency sound waves through the water. The rapid pressure fluctuations cause cavitation: microscopic bubbles that grow and subsequently implode. In the process, they create powerful pressure waves which the cell walls and membranes of mechanically damage micro-organisms, which makes them inactivated or dying.

Advantages of USAF™ cavitating ultrasonic transmitters summarised:
- Effective approach to algae in basin and storage water. This reduces the load on filters and lowers the risk of blockages in pipes and drippers.
- Less biofilm. USAF™ inhibits the build-up of new biofilm and attacks existing biofilm, causing it to gradually detach and be more easily removed from the water system.
- Lower microbiological pressure in the irrigation water. Cavitation damages algae, bacteria and fungi and inactivates viral particles, thereby reducing the likelihood of pathogens spreading via the water.
- A stronger overall water treatment. USAF™ can be deployed independently, but is also excellently combined with existing technologies such as UV, ozone, filtration and chemical disinfection, thereby strengthening the overall chain and minimising risks.
- More efficient use of hydrogen peroxide and other disinfectants. Due to the mechanical destruction of micro-organisms, a lower chemical dosage can be used in many situations.
- Good opportunities to reuse drain water and nutrients. By better controlling the microbiological water quality, recirculation becomes easier and the loss of water and fertilisers can be reduced.
- Significant reduction in the spread of pathogens via the water cycle. By continuously reducing the microbiological pressure, USAF™ reduces the risk of problems spreading through the company via the irrigation water.
- 24/7 treatment. USAF™ operates continuously, 24 hours a day, 365 days a year.
- Zero maintenance and low operational costs. The transmitters are easy to install, require little monitoring and use little energy.
- Nutrients, EC and pH remain unchanged by the USAF™ treatment itself. The operation is mechanical and no substances are added to the water.
- Greater control over water quality and growing reliability. A lower microbiological pressure and a cleaner water cycle contribute to better conditions for a healthy crop.
- Lower total costs of water management. Lower chemical consumption, reduced filtering and cleaning work, fewer blockages, and the reuse of water and nutrients can together provide an attractive payback period.
- Greater stability in the water supply chain. USAF™ works continuously in the background and reduces the daily attention required for algae, biofilm and microbiological contamination.
