Filtralite® Pure Mono-Multi Fine

Mono-Multi

Description

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

Product

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

Advantages

Filtralite® media, with its highly porous structure, enables improved filter efficiency by longer filter runs between backwashes and lower SDI, which means reduced energy and water consumption and higher water production, consequently giving reduced operating costs.
