During flotation process, suspended solids contained in water are coagulated before entering in DAF unit plant. In this moment the flocs begin aggregation because of flocculant reagent. Simeoni next generation system permits the air is being born in that exact instant, embracing flocs and penetrating into them.
Aired-flocs specific weight is extremely reduced, then the flocs begin to lift toward surface, reaching concentration till 3,5%.
By this lift phase the water must be quiet, in order to permit easy flotation of all flocs.
This phase must not be disturbed by turbulences.
