Ibiranga pumice yibirunga (basalt) hamwe nibintu bifatika byibirunga byibinyabuzima byungurura.

Kugaragara no kumiterere: Nta bice bikarishye, birwanya ubukana bwamazi, ntibyoroshye guhagarika, bigabanijwe neza amazi numwuka, hejuru yubutaka, umuvuduko wamafirime wihuta, kandi ntibikunze gukorerwa firime ya mikorobe mugihe cyoza inshuro nyinshi.
Ububabare: Ibirunga byibirunga mubisanzwe ni selile kandi byoroshye, bigatuma ibidukikije bikura neza mumiryango mikorobe.
Imbaraga za mashini: Nk’uko ishami ry’igihugu rishinzwe kugenzura ubuziranenge ribivuga, ni 5.08Mpa, byagaragaye ko ishobora guhangana n’ingaruka zo mu bwoko bwa hydraulic shear ziterwa nimbaraga zitandukanye kandi ikaba ifite ubuzima burebure cyane kuruta ibindi bikoresho byo kuyungurura.
Ubucucike: Ubucucike buciriritse, byoroshye guhagarikwa mugihe cyo gukaraba nta kumeneka ibintu, bishobora kuzigama ingufu no kugabanya ibyo ukoresha.
Ibinyabuzima bihindagurika: ibinyabuzima byo mu birunga biologiya byungurura ibintu birwanya ruswa, inert, kandi ntibigira uruhare mu myitwarire y’ibinyabuzima ya biofilm mu bidukikije.

Amashanyarazi yo hejuru hamwe na hydrophilicity: Ubuso bwibinyabuzima byo mu birunga biofilter bifite umuriro mwiza, bifasha gukura neza kwa mikorobe.Ifite hydrophilicity ikomeye, ubwinshi bwa biofilm ifatanye, n'umuvuduko wihuse.

Ku bijyanye n'ingaruka ku bikorwa bya biofilm: Nkumutwara wa biofilm, itangazamakuru ryibinyabuzima ryitwa biofilter ntacyo ryangiza kandi ntirishobora kugira ingaruka mbi kuri mikorobe ihamye, kandi imyitozo yerekanye ko itagira ingaruka kubikorwa bya mikorobe.
Ibiranga hydraulics biranga urutare rwibirunga biologiya.

Igipimo cyubusa: Impuzandengo yimbere imbere no hanze ni hafi 40%, ifite imbaraga nke zo kurwanya amazi.Mugihe kimwe, ugereranije nibikoresho bisa nkayunguruzo, umubare ukenewe wibikoresho byo kuyungurura ni bike, kandi intego iteganijwe yo kuyungurura nayo irashobora kugerwaho.
Ubuso bwihariye: Hamwe nubuso bunini bwihariye, ubwinshi bwubwinshi, hamwe nubusembure, bifasha guhuza no gukura kwa mikorobe, kubungabunga biomass nyinshi, no koroshya uburyo bwo kohereza misa ya ogisijeni, intungamubiri, n imyanda ikorwa mugihe cya mikorobe metabolism.

Kurungurura imiterere yibintu hamwe nuburyo bwo gutembera kwamazi: Bitewe nuko ibikoresho byibiyunguruzo byibinyabuzima byo mu birunga bitagira ibice kandi bifite ubunini bunini bwa pore kuruta uduce duto twa ceramic, ntibishobora kurwanya amazi kandi bikabika gukoresha ingufu iyo bikoreshejwe.
Ibiranga ni uko ifite imyenge myinshi, uburemere bworoshye, imbaraga nyinshi, izirinda, kwinjiza amajwi, kwirinda umuriro, kurwanya aside na alkali, kurwanya ruswa, kandi idafite umwanda kandi idafite radio.Nicyatsi kibisi cyiza, cyangiza ibidukikije ningufu zibika ingufu.
