The air flotation unit produces a lot of foam
Thread Content
For soybean concentrated phospholipid wastewater, after oil separation, the pH is adjusted, and Pac and Pam are added; then air flotation is carried out. However, excessive foam is generated as a result of this process, which directly affects the efficiency of air flotation. I would appreciate it if experts could help analyze the reasons for this issue.

We produce pressurized dissolved air flotation, vortex air flotation, electrolytic air flotation, shallow-air flotation, eddy current air flotation, and ultrasonic jet-induced air flotation. If the water volume is not large, ultrasound-induced air flotation can be used, eliminating the need for a degassing tank and an air compressor. The bubbles formed are very small, which results in a 20% reduction in costs; moreover, the management is particularly simple.
