Media type

The structure of sera siporax® is open-pored and three dimensional. This structure allows the formation of very effective biofilms that grow into the pores and walls. The biofilm also breaks down nitrate (denitrification) deep within the pore structure where oxygen levels are lower. Not only nitrifying and denitrifying microorganisms grow in the biofilm but also those that break down organic matter. Therefore, the pores do not clog. The biofilm grows and shrinks according to the bioload and thus adapts to the requirements. sera siporax® Professional filter material cleans itself biologically. The pore structure is perfect for being settled by bacteria and archeae.
siporax bio active Pollutant utilizing bacteria remove pollutants such as ammonium and nitrite. Sludge is decomposed faster, and thus the critical pollutants are quickly rendered harmless. The biological equilibrium is stabilized and maintenance intervals become longer.

Supplied with a handy net bag to be placed into canisters, sumps, or behind Matten- and Cornerfilters.
