The Berlin Air-Lift is a high performance, low
cost internal skimmer based on the Berlin Triple-Pass principle. The
Air-Lift is powered by a lime wood air-stone attached to an external air
pump (not supplied), these compact units are easy to install and maintain.
The triple-pass is combined with a powerful
Venturi air injector, greatly enhancing the efficiency of the skimmer. Air
bubbles and protein rich water are concentrated in the narrow inner tube,
ensuring good mixing and maximum surface contact. The air/water mixture
swirls up the inner tube into the wider reaction chamber, causing a
relaxation of the turbulent water and separation of the protein rich foam at
the water surface, which rises into the collection cup. The air bubbles move
down the chamber by the force of the water current until reaching the air
return skirt located at its base. The skirt effectively enlarges the
diameter of the chamber, eliminating the downward force on the air bubbles.
The bubbles then rise up through the chamber against the downward flow of
the water (counter current), causing great turbulence and increased contact
time. The Venturi air injector produces a consistent quantity of fine air
bubbles, ensuring a large surface area for collection of waste materials.
