1. The chemical wastewater treated by the air flotation machine contains a certain amount of air bubbles. If the seepage temperature is high, the air flotation machine will have large bubble particles and cause great losses. It is recommended that users add silicone defoamer, or add defoamer with good compatibility.
2. The shallow air flotation is not well adjusted, the liquid residue is too much, and the interfacial tension of water is very large, so there will be many bubbles.
3. It may also be a problem in the biochemical process. If the foam is white and easy to break, the dissolved oxygen is insufficient and the water seepage load is large.
4. The other is the problem of the machine itself, such as the working state of the flow booster, or if the amount of PAC added is large, the flow back will also lead to the increase of part of the foam.
