Perfiltra®Harbolite® filtration - Applications


PERFILTRA® & HARBORLITE® are applied as a layer in the suspended filter cake, and the joint action with the filter cake achieves optimum filtration performance.

For a 1.5 to 3 mm width (pressure filter), from 200 to 500 gr of PERFILTRA® or HARBORLITE® are required per square meter of filtering area.

The suspended amount of PERFILTRA® or HARBORLITE® pumped in the filter varies between 2% and 6% of the weight of the substance to be filtered.



Adding PERFILTRA® or HARBORLITE® to a liquid before being sent to the filter is known as dispensing.

The amount to be dispensed depends on each application, and ranges between 0.1 to 1% of the weight in suspension, being capable of reaching up to 8% in the case of solids having more difficult filtration (colloids, compressible solids, etc.).

Dispensing of PERFILTRA® or HARBORLITE® may be added directly to the liquid tank to be filtered or added in dosages to the suspension tank in the admission filter.
