Lamella separators - Mode of operation

The actual separation (filtration) of the dirt particles takes place between the individual plates (lamellas). For this pur-
pose, the liquid loaded with dirt particles is guided through the lamellas from the bottom upward with the counter-current principle. Due to the formation of a laminar flow profile, which results between 2 adjacent plates, and the enormously short-
ened sinking path, the particles sediment in an extremely short time.

The particles are deposited on the plate and form an agglomerate when several such particles meet. As soon as these have reached a certain value, they slide downward on the plate due to the force of gravity and can be carried out by a scraper conveyor or a sludge extractor.

Decisive for an effective separation is the so-called dwell time of the liquid in the dirt tank. Only when this has been selected accordingly can the ultra-fine sludge contained in it be effectively separated and discharged.
