Fill media for percolators

Fill media are plastic materials used in percolators to create the development of biomass. Learn more about how they work.

How fill media work

The liquid to be treated is distributed onto the fill media through special rotating distributors, allowing the liquid to percolate through the filter bed without flooding it. The surface of each fill media, which makes up the filter bed, is characterized by the formation of an aerobic biological film, in which bacteria degrade the organic substances present in the liquid.

Materials and shapes of fill media

The choice of material and shape of fill media depends on the chemical and physical properties of the liquid to be filtered and the solid particles to be removed. Find out what the most common materials and shapes used are.

Applications of fill media

Thanks to their effectiveness in separating solid particles from liquids, fill media are widely used in various sectors, including the treatment of civil and industrial wastewater.
