Nitrifying bioreactors for tropical hatchery systems
There are a wide variety of commercially available biofilters and biofilter media
on the market today. In its most basic form, all biofilters perform the same
elementary task of removing total ammonia nitrogen (TAN) from water.
Additionally, biofilters are typically sized according to either the volume of media
(m3) they contain or the specific surface area (m2/m3 of media) of the media used
(Drennal II et al., 2006). The basic design criterion for biofilters is the diumal
waste production and total ammonia nitrogen load in to a system which varies
with the cultured species and biomass load into the system. The quality and the
quantity of the waste are dependent on fish and feed related aspects (Heinsbroek,
1988). When a recirculation system is designed, commonly published data on
waste production must be validated for the specific conditions of the designed
production system (Eding et al., 2006).
