Microflotation - Wikipedia

Microflotation is a further development of standard dissolved air flotation (DAF). Microflotation is a water treatment technology operating with microbubbles of 10–80 μm in size instead of 80-300 μm like conventional DAF units. The general operating method of microflotation is similar to standard recycled stream DAF units.
