Filtralite® Pure HC 1,5-2,5

Description
Filtralite® Pure HC 1,5-2,5 is high quality filter media, manufactured from expanded clay material, used for filtration in drinking water treatment.
Product
Crushed clay aggregates, high density, 1,4-2,5 mm.
Advantages
Filtralite® media, with its highly porous structure, enables improved filter efficiency by longer filter runs between backwashes, which means reduced energy and water consumption and higher water production, consequently giving reduced operating costs.
