How does a daf system work?

Feb. 03, 2018

Wastewater is fed into a diffused air flotation system and hit with a stream of "whitewater", which is recirculated clarified water from the diffused air flotation that's super saturated with dissolved air. As these two mixtures blend together, microscopic bubbles attach to solid particulates, giving them enough buoyancy to surface in the diffused air flotation tank.

As solids accumulate in a floating layer on the top of the diffused air flotation tank, a skimmer gently nudges the sludge toward a discharge hopper.

Any solids that don't float will sink to the "V" bottom of the diffused air flotation tank. Settled solids are concentrated and discharged by an automatically controlled pneumatic drain valve.

The clarified water flows out via an under-over weir on either side of the DAF unit. Some of this water is used in the recirculation loop while the rest flows out of the vessel.
