Filtralite® Pure Mono-Multi

Description

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.

Product

Crushed clay aggregates, high density, 0,8-1,6 mm and low normal density, 1,5-2,5 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.
