Factors affecting the operation of vortex air flotation machine

1. The impact of sewage water quality. Since industrial waste water and sewage generally contain Ca2+ and SO42-, and
some flotation reagents will be added when the vortex air flotation machine is running, after a period of operation, a
layer of scale will adhere to the wheel and bearing of the air flotation machine, which will cause The efficiency of the
air flotation system is reduced.

2. The influence of sewage flow on the treatment effect. The influence of sewage flow on the treatment effect cannot
be ignored. When the air flotation machine is running, it is necessary to ensure that the water distribution in each air
flotation tank is uniform. The change of the flow rate means the change of the amount of pollutants, and the dosage
of the agent needs to be adjusted in time to achieve good results. When the sewage flow is too large, the horizontal
flow rate of the air flotation tank will increase, and the residence time will be shortened, which is unfavorable for the
floating and separation of flocs; too high a flow rate will cause excessive turbulence in the separation zone and cause
the foam-floc combination to break. When the water volume is too large, the height of the outlet weir should be
adjusted in time to prevent sewage from entering the scum system.

3. The effect of flocculant and pH value on air flotation effect. The quality of the air flotation effect is not only affected
by the performance of the air flotation equipment, but also related to the dosage of the flocculant and the pH value.
The dosage of flocculant is not as much as possible. The dosage of organic polymer has a significant impact on the
flocculation effect. Experiments have proved that there is a good dosage for the occurrence of flocculation. When
this amount is exceeded, the flocculation effect will decrease, and if it exceeds this amount, it will have the opposite
protective effect.

　　 The above are the factors that affect the operation of the vortex air floatation machine summarized by the editor.
Of course, it is impossible to only have these few points. There are other factors that everyone should pay attention to.
