About ULTRASONIC ANTIFOULING

The problem

Snails, algae and other microorganisms grow on any object that is in contact with water.
We find them on the rocks, anchor lines, etc. and also of course in the hull of a boat that is not protected.
The application of antifouling paint solves the problem provisionally, since each season it forces us to take the boat out of the water, proceed to remove the remains and repaint.
Since the most polluting products they contained were removed from paints, we have been able to verify that the duration of protection has been considerably reduced.
In any case, if we sand a paint that complies with current regulations without adequate personal protection, we can see that it is not as harmless as it seems.
Most of the paints are self-polishing, which means that little by little they are diluted in the water of our seas or rivers, with the pollution to a greater or lesser degree that this generates.
The development of the ultrasonic technique to prevent fouling has finally managed to put aside the drawbacks of painting and be more respectful of the environment.

The Technical Solution

In the multiple tests carried out, we have been able to verify that by applying ultrasound to the hulls of boats at certain ultrasonic frequencies, the problem of fouling is eliminated.
This is because microorganisms cannot grow on a surface that is subject to ultrasonic signals.
The vibration of the ultrasounds has been adapted so as not to damage any element of the boat at all, nor, of course, the marine fauna.
We work with amplitudes of microns (thousandths of a millimeter), however for microscopic living beings it is enough to prevent their development.
We have developed several models depending on the length of the boats.
The larger the surface to be covered, the more transducers we place to achieve a better distribution of the ultrasound.
