Industrial processes have traditionally control foam through mechanical devices, decreasing tank temperature or adding chemical additives. However, these procedures have the following limitations:
- Decreased performance.
- Quality problems.
- Product losses due to waste.
- Microbial contamination.
- Production delays and stops.
- Obstruction of channels and valves.
- Flooding of air filters.
- Malfunction of control devices
However, high power ultrasonic defoaming systems have proven to be very effective using high power ultrasounds to disperse and control the foam. The creation of an ultrasonic static wave in the air generates nodes and anti-nodes.
The nodes attract matter and so the foam bubbles which implode as a result of the compression forces generated.
