Filtration

Filtration means separation of solid particles from the liquid in which they are suspended. Such particles may be of a different nature: inorganic and organic, including yeast, bacteria and spores, up to particles with a sub-micronic size of 0.2 micron.

Below this level there are molecule aggregates forming colloidal dispersions; these require other filtration techniques.

The different filtration techniques can be summarised as follows:

Separation due to the barrier effect
Separation through adsorption
Filtration through absorption.
Depth filtration.

The diagram below shows that the above-described techniques are predominant in Omniafiltra products.
