Filtralite Clean MC 2,5-4 is a high-quality filter media, manufactured from expanded clay material, used for tertiary filtration of effluent water.
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.
