Is data on backwashing velocities and head loss available for the different qualities of Filtralite?

Yes, data on backwash head loss and expansion and filtration head loss is available for the standard Filtralite fractions. These tests are carried out in our laboratory.

Can Filtralite be used for removal of arsenic from drinking water?

Arsenic can be efficiently removed biologically by using Filtralite as a biofilm media utilizing the large surface area of the material.

Is Filtralite a good selection for removal of iron and manganese?

The large surface area of the Filtralite grains is ideal for biological treatment of iron and manganese. Studies have shown that higher removals are obtained with Filtralite compared to other biofilter-media.
