HH recirkulirajoči sistem ribogojstva --- Biofilter

Biofilter v reaktor dodaja določeno količino suspendiranih bioloških nosilcev, poveča prezračevanje in meša v naravnih pogojih, uporablja hranila v ribogojni vodi in se opira na funkcionalne nitrificirajoče bakterije, denitrificirajoče bakterije in druge aktivne mikroorganizme, da se postopoma oblikujejo obogateni aktivni biofilm na površino; the biofilm metabolizes and decomposes nutrients such as C, N, and P in the water through its own biochemical reactions, and converts free ammonia nitrogen and nitrite in the aquaculture water that are toxic and harmful to the aquaculture objects into non-toxic and harmless nitrates, nitrogen gas, etc., thereby achieving continuous purification and regeneration of the voda ribogojstva.
