Filtralite Nature NC 2–10 is a high-quality filter media, manufactured from expanded clay material, used for filtration and purification of waste and effluent water for dispersed settlements.
Filtralite filter media, with its highly porous structure, enables large microbial growth surface for biological filtration which means improved filter capacity and reduced operational costs.
