Tornado II Protein Skimmer

Tornado II Protein Skimmer Product Details
The surface of an air bubble attracts dissolved substances out of the water. Because of the adhesion of the bubbles these substances, like chemicals, waste particles, colourants and algae, are concentrated. By means of a venturi, air is mixed with water. By forcing this mixture through the filter material (the white ''KNS'' bio rings) to a lower drain, there is a long contact between air and water. This changes the surface tension of the water continuously and a thick foam arises. The foam is separated from the cleared water by a grid and drained. Different kinds of pollution are caught in the foam and drained. This makes the filter Tornado Protein Skimmer self cleaning. Dissolved substances like; phosphates, ammonia, humus acids, colourants, proteins and a number of heavy metals, are filtered out of the water and drained together with the foam. The extraction of dissolved substances is not possible with normal filters and can only be done if chemicals are added.
