Filtralite Pure Mono-Multi combines two types of Filtralite Pure filter media with different densities and sizes (Filtralite Pure HC 0,8–1,6 and Filtralite Pure NC 1,5–2,5) to improve even more filter runs and production capacity for filtration in drinking water treatment.
Filtralite filter 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.
