The Degassing Process
When the cycle is in low pressure, the ultrasonic waves will create small vacuum bubbles as well as voids inside the liquid. Therefore, a large number of tiny bubbles produce a high number of bubbles in the surface area. In addition, these bubbles are distributed perfectly and efficiently into the liquid.
On the other hand, the dissolved gas will drift through the low pressured vacuum bubble inside the larger surface area while increasing the size of bubbles. The sound waves will hold up the coalescence as well as the touching of the adjacent bubble which will eventually lead to the hastened bubble growth.
The sonication of the waves also helps in the shaking of bubbles inside the vessel surface to go up and release the captured gas to the environment.
