flow ration between air and water - AERATION PUMP
flow ration between air and water - AERATION PUMP
(OP)
Hi folks,
I'm trying to get more opionions of someone who has experience with aeation pump for DAF unit. As I know flow ratio, I need opinion of you guys with experience in this field what is best flow ration between air and water, when sizing the aeration pump.
Thanks,
Andreas

I need best of the best
type of pump is : EDUR - PBU Series
Thanks

If you read the sales flyer for the EDUR - PBU Series, the manufacturer does not understand how DAF systems work. In the traditional DAF design, the air is dissolved in water, not entrained or entrapped. When the pressure is released with the control valve, the air will come out of solution, thereby forming minute bubbles.

In the old days (and for some other aeration applications people put eductors in the line and let the water suck in air, but it is easy to end up with too much air.

DAF is for the treatment of industrial wastewater.
Do you have experience with DAF system /design, so what PUMP you suggest here, I want best system best pump no matter how much cost all together, just give me what is best solution.

Conversely, you can use one of the DAF pumps that inject the air. However, read the performance claims with skepticism.
The DAF supplier should be furnishing a complete system that includes the air injection system.
