Features:
HOLLOW BIO BEADS is a biological filter material with an innovative patented hollow shape design, which favors the formation of denitrification zones in depth. Made up of inert ceramic, it has a large usable surface, about 700 sqm / L. Thanks to the Open PorosityTM technology, it has a particular structure with open macropores that guarantees perfect colonization and at the same time delays the clogging phenomena, extending maintenance times. Its shape allows a different distribution of NH + 4 and NO-2 ions which can therefore be actively absorbed. It has a low impact on tds and does not alter the pH value (pH 7 / 7.5). Most of the pores are localized as a percentage in the range 45/55 µm and 10 nm, this implies that the surface is biologically and really usable for bacterial colonization. |
