SALINE - DAF (Dissolved Air Flotation)

Principle of a Dissolved Air Flotation Unit In a flotation unit, particles/flocks will float to the surface with the injection of air and will automatically and continuously be removed by a scraper mechanism. On one hand, the flotation unit can be equipped with plate pack technology which increases the separation area and thus ensures that even the smallest flocks are removed from the waste water.
On the other hand, the plate pack technology can also be excluded to ensure the unit can handle a higher solid loading.

Due to the optimal AERATION system and the sludge thickening/scraper system, a high dry solids content of floation sludge will be reached. The on-built AERATION system is equipped with non-clogging aeration devices and its unique design ensures formation of the very fine air bubbles required. The flotation unit includes automatic drain valves for removing any settled material. The unit selection and the material selection is based on: the type of wastewater, the hydraulic capacity and sludge handling capacity.
