Filtralite® Pure NC 1,5-2,5

Description
Filtralite® Pure NC 1,5-2,5 is high quality filter media, manufactured from expanded clay material, used for filtration in drinking water treatment.
Filtralite® Pure NC 1,5-2,5 is also used in Filtralite® Pure Mono-Multi.
Product
Crushed clay aggregates, normal low-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.
