Filtralite® Nature P 0,5-4
Description
Filtralite® Nature P 0,5-4 is high quality filter media, manufactured from expanded clay material, used for filtration and purification of waste and effluent water for dispersed settlements.
Product
Crushed clay aggregates, normal low-density, 0,5-4 mm. Activated surface for P-binding.
Advantages
Filtralite® media, with its highly porous structure, enables large microbial growth surface for biological filtration which means improved filter capacity and reduced operational costs. Filtralite® Nature P media, with its high content of limestone, improves phosphorus removal from waste and effluent waters.
