Flotation system NFF
High capacity flotation unit
The NFF is a flotation system by which the impurities are separated from the water by using air.
With Induced Air the rising velocity of a particle is increased by adding air bubbles of 100-150
micron to the water by a self air sucking aeration system which is installed just after the inlet construction.
The air bubbles stick to the particles after which they rise to the surface from where they are
scraped off by a scraper mechanism. Any sediment wil be drained off by standard installed drain valves.
