AquaSkim

La foam fractionation (fractionation of the foam or skimming) is one of the physico-chemical methods that involves the separation of solutes (dissolved molecules) and particulate matter (suspended materials) through their aptitude to bind to the air bubbles that rise upwards (foam). The materials removed by foam fractionation are mainly surfactants. Surfactants are substances that have the property of lowering the surface tension of a liquid; they are dissolved molecules that have a tendency to concentrate in the air / water interface created by an air bubble. In a foam fractionation process applied to aquaculture, proteins, as well as colloids, they are transported by the solution in the moving air bubbles through convective diffusion.

Aquaskim is a patented skimmer for purification and finishing plants for live bivalve molluscs (mussels, clams, oysters, etc.) which has the function of removing the protein phase contained in the water through the process of "foam fractionation" or "skimming" which is activated by introducing air with the Venturi effect into the water in a reaction chamber, and thus causing the phenomenon of convective diffusion that transports the substances of a protein nature and removes them together with the air bubbles that come out. More, compared to skimmers used in the state of the art, the foam is chemically treated in a second reaction chamber with a substance which is absolutely safe from a health point of view, and immediately transformed into an aqueous solution containing waste substances, which can be removed in special containers, thus avoiding the use of dirty foam containers, limiting cleaning operations and significantly improving the management of the shellfish purification plants.
