Makhalidwe a volcanic pumice (basalt) ndi mawonekedwe a volcanic rock biological filter materials.

Maonekedwe ndi mawonekedwe: Palibe tinthu tating'onoting'ono tating'ono tating'ono, kukana kutsika kwamadzi, kosavuta kutsekereza, madzi ndi mpweya wogawanika mofanana, pamwamba pake, filimu yofulumira yolendewera, komanso kuchepa kwa filimu yowonongeka mobwerezabwereza.
Porosity: Mwala wa mapiri ndi ma cell komanso porous, zomwe zimawapangitsa kukhala malo abwino kwambiri okulirapo m'magulu ang'onoang'ono.

Mphamvu zamakina: Malinga ndi dipatimenti yoyang'anira zaubwino wa dziko, ndi 5.08Mpa, yomwe yatsimikiziridwa kuti imapirira kumeta ubweya wamagetsi amphamvu zosiyanasiyana ndipo imakhala ndi moyo wautali wautumiki kuposa zida zina zosefera.
Kachulukidwe: Kachulukidwe kakang'ono, kosavuta kuyimitsa pakutsuka msana popanda kutayikira, komwe kumatha kupulumutsa mphamvu ndikuchepetsa kugwiritsa ntchito.
Kukhazikika kwamankhwala achilengedwe: volcanic rock biological filter material imalimbana ndi dzimbiri, inert, ndipo satenga nawo gawo pazachilengedwe za biofilm m'chilengedwe.

Magetsi apamtunda ndi hydrophilicity: Pamwamba pa miyala ya volcanic biofilter imakhala ndi mtengo wabwino, womwe umathandizira kukula kosasunthika kwa tizilombo tating'onoting'ono.Ili ndi hydrophilicity yamphamvu, kuchuluka kwa biofilm yolumikizidwa, komanso kuthamanga kwachangu.
Pankhani yakukhudzidwa ndi zochitika za biofilm: Monga chonyamulira cha biofilm, nyimbo zamtundu wa volcanic rock biofilter ndizopanda vuto ndipo zilibe choletsa pa tizilombo tokhazikika, ndipo mchitidwe watsimikizira kuti sizikhudza ntchito za tizilombo tating'onoting'ono.

Makhalidwe a Hydraulics a volcanic rock biological filter material.
Mlingo wopanda kanthu: Wapakati porosity mkati ndi kunja ndi mozungulira 40%, yomwe imakhala yochepa kukana madzi.Nthawi yomweyo, poyerekeza ndi zida zosefera zofananira, kuchuluka kofunikira kwa zinthu zosefera ndizochepa, ndipo cholinga chosefa chomwe chikuyembekezeka chingathenso kukwaniritsidwa.
Malo enieni: Ndi malo akuluakulu enieni, okwera kwambiri, komanso osasunthika, amathandiza kuti tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda tizilombo toyambitsa matenda, zomwe zimathandizira kuti mpweya, zakudya, ndi zinyalala zomwe zimapangidwira panthawi ya tizilombo. metabolism.
Zosefera mawonekedwe ndi mawonekedwe amadzi oyenda: Chifukwa chakuti zida zosefera zamtundu wa volcanic rock ndi zopanda zisonga ndipo zili ndi pore yayikulupo kuposa tinthu ta ceramic, sizimakana kuyenda kwamadzi ndikusunga mphamvu zikagwiritsidwa ntchito.

Makhalidwe ake ndi oti ali ndi pores ambiri, kulemera kwake, mphamvu zambiri, kutsekemera, kuyamwa kwa mawu, kuteteza moto, asidi ndi alkali kukana, kukana dzimbiri, komanso kulibe kuipitsidwa komanso kosatulutsa ma radio.Ndi abwino zachilengedwe wobiriwira, zachilengedwe wochezeka ndi mphamvu zopulumutsa yaiwisi.
