Each immersed jet creates turbulences as a result of the resistance of the medium in which it is immersed and at the end of its effective range the complete introduced energy is broken down into turbulent flows. These turbulent flows observed as a whole are local, thus are small-scale. It is however indeed these small-scale turbulences which have a strong eroding effect and it is the object of the invention to produced as high a number as possible of small-scale turbulences and to distribute these over a large volume. Large volume is to be understood as for example 3000-4000 m<3 >on a surface of 2000 m<2 >and a height of 2 m as is the case with a storage tank of 50 m diameter and a liquid column of 3 m. The problem thus lies in the optimal distribution of the introduced energy.
