Ibuye ry’ibirunga (rizwi cyane nka pumice cyangwa basalt ifite imyenge) ni ibikoresho bikora neza kandi birengera ibidukikije, rikaba ari ibuye ry’agaciro gakomeye rigizwe n’ibirahure by’ibirunga, imyunyu ngugu, n’udusimba nyuma y’iruka ry’ikirunga. Ibuye ry’ibirunga rigizwe n’imyunyu ngugu myinshi n’ibintu bike nka sodium, manyeziyumu, aluminiyumu, silikoni, kalisiyumu, titaniyumu, manganese, icyuma, nikeli, kobaltiyumu, na molybdenum. Ntirigira imirasire kandi rifite imiraba ya rukuruzi ya infrared. Nyuma y’iruka ry’ikirunga ritagira impuhwe, nyuma y’imyaka ibihumbi n’ibihumbi, abantu barimo kugenda bavumbura agaciro karyo. Ubu ryaguriye imirima yaryo mu mirima nko mu bwubatsi, kubungabunga amazi, gusya, ibikoresho byo kuyungurura, amakara ya barbecue, ubusitani, ubuhinzi butagira ubutaka, n’ibicuruzwa by’imitako, rigira uruhare rudasimburwa mu nganda zitandukanye.

Ibiranga pumice y'ibirunga (basalt) n'imiterere y'ibikoresho by'ibinyabuzima by'urutare rw'ibirunga.
Ishusho n'imiterere: Nta duce duto cyane, nta bushobozi bwo guhangana n'amazi atemba, ntabwo byoroshye kuziba, amazi n'umwuka bikwirakwira ku buryo bungana, ubuso bugoye, umuvuduko wihuse wo kumanika firime, kandi ntibikunze kwibasirwa na mikorobe mu gihe cyo kuzisukura kenshi.

Ubwinshi bw'amabuye: Amabuye yo mu birunga afite utunyangingo karemano kandi afite imyenge, bigatuma aba ahantu heza ho gukura ku mikorobe.
Ingufu za mekanike: Dukurikije ishami rishinzwe kugenzura ubuziranenge ku rwego rw'igihugu, ni 5.08Mpa, byagaragaye ko ishobora kwihanganira ingaruka zo gukata amazi mu buryo butandukanye kandi ikaba imara igihe kirekire kurusha ibindi bikoresho byo kuyungurura.
Ubucucike: Ubucucike buri hagati, bworoshye kubuhagarika mu gihe cyo gukaraba inyuma nta kintu gisohoka, bishobora kuzigama ingufu no kugabanya ikoreshwa.

Ubudahangarwa bwa biochemical: Ibikoresho bya biofilter byo mu mabuye y'ibirunga birwanya ingese, ntibigira ingaruka mbi, kandi ntibigira uruhare mu mikorere ya biofilms mu bidukikije.
Amashanyarazi yo ku butaka n'ubushyuhe bw'amazi: Ubuso bw'urutare rw'ibirunga rufite ingufu nziza, bituma udukoko duto dukura neza. Rufite ubushyuhe bwinshi bw'amazi, ingano nini ya biofilm ifatanye, kandi rukora umuvuduko wihuta.

Ku bijyanye n'ingaruka ku bikorwa bya biofilm: Nk'igikoresho gitwara biofilm, biofilter yo mu mabuye y'ibirunga nta cyo itwaye kandi nta ngaruka igira ku mikorobe zidahinduka, kandi imyitwarire yagaragaje ko itagira ingaruka ku bikorwa bya mikorobe.
Imiterere y'ibikoresho byo kuyungurura amabuye y'ibirunga mu buryo bwa Hydraulics.

Igipimo cy'ubusa: Impuzandengo y'ubuso bw'amazi imbere n'inyuma ni hafi 40%, ibyo bikaba bifite ubushobozi buke bwo guhangana n'amazi. Muri icyo gihe, ugereranije n'ibikoresho bisa byo kuyungurura, ingano y'ibikoresho byo kuyungurura ikenewe ni nto, kandi intego yo kuyungurura itegerejwe ishobora kugerwaho.
Ubuso bwihariye: Kubera ko ifite ubuso bunini bwihariye, ifite imyenge myinshi, kandi idafite amazi menshi, ituma mikorobe zigera ku rundi ruhande kandi zigakura, ikomeza kuba nyinshi mu mikorobe, kandi yorohereza uburyo bwo kohereza umwuka wa ogisijeni, intungamubiri, n'imyanda ikomoka mu gihe cy'ihinduka ry'imikorobe.
Imiterere y'ibikoresho byo kuyungurura n'imiterere y'amazi: Bitewe n'uko ibikoresho byo kuyungurura by'ibinyabuzima byo mu mabuye y'ibirunga ari uduce tudafite indobo kandi bifite umwobo munini ugereranyije n'uduce twa ceramic, bigira ubudahangarwa buke ku mazi kandi bikagabanya ingufu iyo bikoreshejwe.

Ibiranga ni uko ifite imyenge myinshi, uburemere bwayo bworoheje, imbaraga nyinshi, ubushyuhe, ifata amajwi, irinda umuriro, irwanya aside na alkali, irwanya ingese, kandi ntihumanya kandi ntihumanya ikirere. Ni ibikoresho fatizo byiza by’icyatsi kibisi, birengera ibidukikije kandi bizigama ingufu.
