Iimpawu ze-volcanic pumice (basalt) kunye neempawu ezibonakalayo zezinto zokucoca ii-volcanic rock biological.

Inkangeleko kunye nokuma: Akukho masuntswana abukhali, akukho ukumelana kwamanzi, akukho lula ukuwavala, amanzi nomoya zisasazeke ngokulinganayo, umphezulu orhabaxa, isantya esikhawulezayo sokuxhoma ifilimu, kwaye ayichaphazeleki lula kukwahlukana kweentsholongwane ngexesha lokuhlanjwa ngokuphindaphindiweyo.
Ukuvuleka: Amatye entaba-mlilo akhiwe ngokwendalo kwaye aneembobo, nto leyo eyenza ukuba abe yindawo efanelekileyo yokukhula kwiindawo ezihlala iintsholongwane.

Amandla oomatshini: Ngokwesebe lokuhlola umgangatho lesizwe, yi-5.08Mpa, ebonakaliswe ukuba iyamelana nemiphumo yokuchetywa kwe-hydraulic yamandla ahlukeneyo kwaye inobomi obude kakhulu kunezinye izixhobo zokucoca.
Uxinano: Uxinano oluphakathi, kulula ukuluxhoma ngexesha lokuhlamba umva ngaphandle kokuvuza kwezinto, nto leyo enokonga amandla kwaye inciphise ukusetyenziswa.
Uzinzo lweekhemikhali zebhayoloji: Izinto zesihluzo sebhayoloji zelitye lentaba-mlilo azinamhlwa, azinamsebenzi, kwaye azithathi nxaxheba kwimpendulo yebhayoloji yebhayoloji kwindalo esingqongileyo.

Umbane ongaphezulu kunye nokuthambeka kwamanzi: Umphezulu we-biofilter yelitye lentaba-mlilo unetshaja entle, enceda ukukhula okuzinzileyo kweentsholongwane. Ine-hydrophilicity enamandla, inani elikhulu le-biofilm enamatheleyo, kunye nesantya esikhawulezayo.
Ngokuphathelele impembelelo kumsebenzi we-biofilm: Njengesithwali se-biofilm, i-biofilter media yelitye lentaba-mlilo ayinabungozi kwaye ayinayo impembelelo yokuthintela kwiintsholongwane ezisisigxina, kwaye indlela yokusebenza iye yabonisa ukuba ayichaphazeli umsebenzi weentsholongwane.

Iimpawu zeHydraulics zezinto zokucoca iilitye zentaba-mlilo.
Izinga lokungafumani: Umndilili wokuvuleka ngaphakathi nangaphandle umalunga ne-40%, nto leyo enokumelana okuncinci namanzi. Kwangaxeshanye, xa kuthelekiswa nezinto ezifanayo zokuhluza, ubungakanani obufunekayo bezinto zokuhluza buncinci, kwaye injongo yokucoca elindelekileyo nayo inokufezekiswa.
Indawo ethile yomphezulu: Njengoko inendawo enkulu ethile, ukuvuleka okuphezulu, kunye nokungangeni kakuhle, inceda ekudibaneni nasekukhuleni kweentsholongwane, igcina i-biomass ephezulu yeentsholongwane, kwaye iququzelela inkqubo yokudluliselwa kobuninzi beoksijini, izondlo, kunye nenkunkuma eveliswa ngexesha le-metabolism yeentsholongwane.
Imilo yezinto zokucoca kunye nepatheni yokuhamba kwamanzi: Ngenxa yokuba izinto zokucoca zebhayoloji zamatye entaba-mlilo azinazo iingceba kwaye zinobukhulu obukhulu beembobo kunee-ceramic particles, azinawo amandla amaninzi okuchasana nokuhamba kwamanzi kwaye zigcina ukusetyenziswa kwamandla xa zisetyenziswa.

Iimpawu zayo zezokuba inemingxuma emininzi, ubunzima bayo bulula, amandla aphezulu, ubushushu, ukufunxwa kwesandi, ukuthintela umlilo, ukumelana ne-asidi kunye ne-alkali, ukumelana nokugqwala, kwaye ayinangcoliseko kwaye ayinayo i-radioactive. Yinto eluhlaza yendalo efanelekileyo, enobuhlobo nokusingqongileyo kwaye igcina amandla.
