I-Breathing Biological Ring ingumkhiqizo omusha emkhakheni we-bio-fitration.Inokuthungwa okuqinile kanye nezakhi ezincane eziningi, ezidlala indima ebalulekile ekuhlanzeni imvelo yamanzi endaweni ezungezile. ,ikhiqizwa ngokubalwa kwezinga lokushisa eliphezulu ngemva kokuhlanganiswa.Yengeza amaminerali abalulekile kanye nezidingo zamanzi zezakhi ezincane, ngaleyo ndlela isize ukuhlanzwa kwamanzi kanye nokululama, inikeze indawo yokuhlala evumayo ye-biota.I-potous surface, ngemva kwenqubo ekhethekile yokushisa okuphezulu, okusheshisa ukusungulwa nokukhiqizwa kabusha kwesistimu yokufaka i-nitrifying. Indawo engaphezulu ine-capillary porosity ephezulu engenekayo, esiza ukugcwala kwamanzi ngokushesha, ihlinzeke indawo yokuzalanisa amagciwane e-aerobic kanye ne-anaerobic futhi ivuselela amagciwane e-aerobic kanye ne-anaerobic kanye ngokuphumelelayo.ukulawula ukuqoqwa kwe-nitrite ne-nitrate.
