Biofilter is the core equipment of circulating water treatment.Under the condition that the total amount of circulating water is fixed, the total amount of nitrogen input keeps increasing. Under the action of a series of organisms, these nitrogen-containing substances are converted into ammonia or ni trite dissolved in water. The continuous accumulation of these substances will lead to the poisoning of aquatic organisms.Therefore, these ammonia nitrogen and other substances must be converted into non-toxic substances in circulating aquaculture.Biochemical box is through a certain carrier, the cultivation of biochemical bacteria, ammonia nitrogen and other substances in water decomposition.However, biochemical filtration requires a certain amount of pretreatment,
The working principle of
Box-type biological filter (biological filter tank) is blue spirit in a series of seawater circulating water aquaculture water treatment equipment constantly sum up experience in the production of a biological filter vessel, its exquisite design let the water always stay within the scope of a certain velocity, can guarantee the biofilm attached on the biological filter material, as soon as possible to play with the whole system the most powerful effect.
Biological Filter for aquaculture
For nitrification and CO 2 degassing process
for filtering from high ammonia's and ni trites from the aquaculture fish tanks
the sizes from 40 till 360 m3 water flow a hr are available
possibility for customized made bio filters
Surface areas up to 2000 m2/m3
usage from different materials for filtration so as : coral sand , ceramic rings, Bio ball , Bio Cord
