HOW DOES FILTRATION OCCUR?

Filtration occurs after theseparation of the solids in suspension that flow through a fluid through a mechanical porous medium such as a sieve or filter. By the force of gravity or by the action of a pump, the filter retains the larger solids in the fluid and allows the smaller particles to pass through the holes in the screen.

HOW IS FILTRATION CAPACITY DETERMINED?

The capacity to retain solids is mainly determined by the size of the mesh holes, however, there are a number of characteristics that should be taken into account when choosing the right filter. It may be necessary to check the chemical compatibility of the filter with the fluid, the degree of permeability of the fluid and its resistance to filtration pressures, the capacity to retain solids, its maintenance and its service life.
