FILTER LINE BIO BEADS
HOLLOW BIO BEADS is a biological filtering material with a patented innovative design in the shape of a quarry, which promotes deep formation of denitrification zones. Consisting of inert ceramics has a large usable surface, about 700 sqm/L.
Thanks to the Open PorosityTM technology, it has a special structure with open macropores that guarantees a 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 pores are located 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.
