Flottaflo - Dissolved Air Flotation (DAF) Unit - Brochure

After the sieving stage, the wastewater is sent into the flotation unit. Micro-bubbles are injected under pressure into the liquid. These microscopic bubbles with a diameter of between 20 and 50 μm activate the flotation and raise the grease particles to the surface, forming a layer of scum to be scraped off.
