How do our USAF ultrasonic transmitters work?
Our ultrasonic transmitters constantly send sound at very high frequencies into the water, which causes cavitation. Cavitation is the creation of gas bubbles between the water molecules, which become larger and larger due to the continuous sound, eventually the gas bubbles become unstable and implode.
As you can see in the top figure, the implosion causes a pressure wave of 2,000 bar. The pressure wave travels through the water at 1,250km/h, destroying the microorganisms present, killing the algae and sinking to the bottom.
This is difficult to see with the human eye, so we made the video below, which clearly shows the impact of the pressure waves. The pressure waves only have an effect on micro organisms...and aluminium foil because it is very thin ;-) These pressure waves have no impact on sails, walls, fish or mammals. In the short video below you can see the impact after a very short time, but our transmitters are usually on 24/7, 365 days a year, imagine the result.
Advantages of using ultrasonic transmitters in horticulture:
Basin water remains free of algae, the filters need to be cleaned less often and there are far fewer blockages in the pipes and drippers.
By using ultrasonic transmitters, you counteract the formation of biofilm, and existing biofilm is broken down after the installation of our equipment.
More yield and less wastage because the plants need to spend less energy defending themselves against bacteria, fungi and viruses in the water.
Far fewer pesticides are needed, as water quality is greatly improved. In many cases, a cheaper and more environmentally friendly product is sufficient.
Fertilisers in the drain water can be reused.
Water is a major spreader, and using our ultrasonic water disinfectors makes this a thing of the past.
Short payback period, as the plants yield more, have less waste, fertilisers can be reused and also (much) fewer pesticides need to be used.
