Kapangidwe kake ndi kakang'ono ka zinthu zopangidwa ndi biofilter ya miyala ya volcano kamadziwika ndi pamwamba ndi ma micropore, zomwe ndizofunikira kwambiri pakukula ndi kuberekana kwa tizilombo toyambitsa matenda pamwamba pake kuti apange biofilm. Zipangizo zoyeretsera miyala ya volcano sizimangochiza madzi otayira a m'matauni okha, komanso madzi otayira achilengedwe a m'mafakitale, ngalande zapakhomo, madzi oipitsidwa ang'onoang'ono, ndi zina zotero. Zingathenso kusintha mchenga wa quartz, carbon activated, anthracite ngati fyuluta yoyeretsera madzi. Nthawi yomweyo, zimathanso kuchita chithandizo chapamwamba cha madzi akumbuyo pambuyo pa njira yachiwiri yoyeretsera madzi otayira, ndipo madzi oyeretsera amatha kufikira muyezo wogwiritsiranso ntchito madzi. Zingagwiritsidwe ntchito pobwezeretsanso madzi.

Kapangidwe ka mankhwala a zinthu zopangidwa ndi zinthu zopangidwa ndi miyala ya volcano ndi motere:

1. Kukhazikika kwa mankhwala a tizilombo toyambitsa matenda: Zinthu zopangidwa ndi biofilter ya miyala ya volcano sizimakhudzidwa ndi dzimbiri, sizimalowa m'malo, ndipo sizimagwira ntchito pa biofilm yomwe imapangidwa m'chilengedwe.

2. Magetsi pamwamba ndi kusinthasintha kwa madzi: pamwamba pa biofilter ya miyala ya volcano ili ndi mphamvu yabwino, zomwe zimathandiza kukula kwa tizilombo toyambitsa matenda. Ili ndi kusinthasintha kwa madzi kwambiri, biofilm yolumikizidwa yambiri komanso liwiro lake lachangu.

3. Monga chonyamulira biofilm, biofilter ya miyala ya volcano ilibe vuto lililonse komanso loletsa tizilombo toyambitsa matenda tomwe sitikuyenda, ndipo zatsimikiziridwa kuti sizikhudza ntchito ya tizilombo toyambitsa matenda.

Kagwiridwe ka ntchito ka hydraulic ka biofilter ya miyala ya volcano ndi motere:

1. Kutsekeka kwa madzi: kutsekeka kwa madzi mkati ndi kunja ndi pafupifupi 40%, ndipo kukana madzi ndi kochepa. Nthawi yomweyo, poyerekeza ndi mtundu womwewo wa fyuluta, kuchuluka kwa fyuluta yofunikira ndi kochepa, zomwe zingakwaniritsenso cholinga chosefera chomwe chikuyembekezeka.

2. Malo enieni a pamwamba: malo akuluakulu a pamwamba, ma porosity ambiri komanso osagwira ntchito, zomwe zimathandiza kuti tizilombo toyambitsa matenda tizilumikizana ndi kukula, zimasunga michere yambiri ya tizilombo toyambitsa matenda, komanso zimathandiza kuti mpweya, michere ndi zinyalala zisamayende bwino zomwe zimapangidwa mu kagayidwe ka tizilombo toyambitsa matenda.

3. Mawonekedwe a zinthu zosefera ndi momwe madzi amayendera: chifukwa zinthu zosefera za m'thanthwe la volcano sizili ndi ma granular, ndipo mainchesi ambiri a ma pore ndi akulu kuposa ceramsite, zimakhala ndi kukana pang'ono kwa madzi ndipo zimasunga mphamvu.
