Iimpawu ze-volcanic pumice (basalt) kunye neempawu ezibonakalayo ze-volcanic rock biological filter materials.

Ukubonakala kunye nokuma: Akukho zincinci ezibukhali, ukuchasana okuphantsi kokuhamba kwamanzi, akulula ukuvimba, amanzi asasazwa ngokulinganayo kunye nomoya, indawo erhabaxa, isantya sokuxhoma ifilimu ekhawulezayo, kwaye incinci kakhulu kwi-microbial film detachment ngexesha lokugungxulwa ngokuphindaphindiweyo.
I-Porosity: Amatye e-volcanic ngokwendalo aneeselula kwaye aneentunjana, ezenza ezona ndawo zikhula kakuhle kuluntu lwe-microbial.

Amandla oomatshini: Ngokwesebe lokuhlola umgangatho wesizwe, yi-5.08Mpa, engqinwe ukuba inokumelana neziphumo zokucheba nge-hydraulic yamandla ahlukeneyo kwaye inobomi benkonzo obude kakhulu kunezinye izixhobo zokucoca.
Ubuninzi: Ubuninzi obuphakathi, kulula ukuxhoma ngexesha lokuhlamba umva ngaphandle kokuvuza kwezinto, ezinokonga amandla kunye nokunciphisa ukusetyenziswa.
Uzinzo lwekhemikhali yebhayoloji: imathiriyeli yebhayoloji yentaba yentaba-mlilo iyamelana nokuhlwa, inert, kwaye ayithathi nxaxheba kwimpendulo yebhayoloji yebhayoloji kokusingqongileyo.

Umbane ongaphezulu kunye ne-hydrophilicity: Umphezulu we-volcanic rock biofilter unentlawulo elungileyo, ekhuthaza ukukhula okuzinzileyo kwemicroorganisms.Ine-hydrophilicity eyomeleleyo, isixa esikhulu se-biofilm eqhotyoshelweyo, kunye nesantya esikhawulezayo.
Ngokwempembelelo kumsebenzi we-biofilm: Njengomntu ophethe i-biofilm, i-volcanic rock biofilter media ayinabungozi kwaye ayinayo impembelelo yokuthintela kwii-microorganisms ezisisigxina, kwaye ukuziqhelanisa kuye kwangqina ukuba ayichaphazeli umsebenzi we-microorganisms.

Iimpawu zeHydraulics zevolcanic rock biological filter material.
Izinga elingenanto: Umyinge we-porosity ngaphakathi nangaphandle ujikeleze i-40%, enokumelana okuphantsi kwamanzi.Ngexesha elifanayo, xa kuthelekiswa nezinto ezifanayo zokucoca, inani elifunekayo lezinto zokucoca zincinci, kwaye injongo yokucoca ekulindelekileyo inokufezekiswa.
Indawo ethile yendawo ethile: Ngommandla omkhulu ocacileyo, i-porosity ephezulu, kunye nokungangeni, inceda ukunxibelelana kunye nokukhula kwe-microorganisms, ukugcina i-biomass ephezulu ye-microbial, kunye nokuququzelela inkqubo yokudlulisa i-oksijini, izondlo, kunye nenkunkuma eyenziwa ngexesha le-microbial. imetabolism.
Ukumila kwemathiriyeli yesihluzi kunye nepateni yokuhamba kwamanzi: Ngenxa yokuba imathiriyeli yebhayoloji yentaba-mlilo yentaba-mlilo ingamasuntswana angatsolanga kwaye inobukhulu bepore enkulu kunamasuntswana e-ceramic, azikwazi ukumelana nokuhamba kwamanzi kwaye zonga ukusetyenziswa kwamandla xa esetyenziswa.

Iimpawu zayo kukuba ineepores ezininzi, ubunzima obukhanyayo, ukomelela okuphezulu, ukugquma, ukufunxa isandi, ukuthintela umlilo, ukuxhathisa kweasidi kunye nealkali, ukumelana nokubola, kwaye ayingcoliseki kwaye ayinayo i-radioactive.Yimathiriyeli ekrwada yendalo efanelekileyo, ehambelana nokusingqongileyo kunye nokonga amandla.
