Dry precoat for coarse filtration composed of cellulose fibers of different lengths and siliceous material with selected granulometry. Filtrobril HM forms a homogeneous pad, with a high degree of absorption and good adherent to the filtration supports, whether they are horizontal or vertical plates. In case of accidental interruption of filtration, Filtrobril pad does not fall down but ensures a homogeneous separation from the plates at the end of the operation.
