Filter Innovations has recently completed designing and testing it's own version of the Dissolved Air Filtration system (DAF). After successful testing with our prototypes we've finalized the design and have begun production on our first units. Check back soon for more detailed information on one of our newest and most innovative deigns yet.

How does it work?

A stream of air continuously generates at the base of a flotation cell where it travels up the counter-current of the flow going down. The counter current is produced from the solids of water being fed in to the system.

This water, which contains solid waste, enters the zone of distribution close to the interface. The polymer mixture enters an area that agitates the mixture that sticks to the solids that are meant to be separated. While entering the zone of distribution, the particles that are coagulated in the water, stick to the bubbles of air. These then travel upward and are evacuated as soon as it reaches the surface of the water. On the other hand, heavier cleaner water without the coagulated particles is evacuated by exiting the system away from the dirty scum. The scum, which accumulates with the top the column, overflows in an intermittent way or is continuously skimmed away by a system of skimmers.
