Itshe lentaba-mlilo (elivame ukubizwa ngokuthi i-pumice noma i-basalt enezimbotshana) liyinto esebenzayo futhi evumelana nemvelo, okuyitshe eliyigugu kakhulu elinezimbotshana elakhiwe ingilazi yentaba-mlilo, amaminerali, namabhamuza ngemva kokuqhuma kwentaba-mlilo.Itshe lentaba-mlilo liqukethe inqwaba yamaminerali kanye nezakhi zokulandelela ezifana ne-sodium, i-magnesium, i-aluminium, i-silicon, i-calcium, i-titanium, i-manganese, insimbi, i-nickel, i-cobalt, ne-molybdenum.Ayinamisebe futhi inamaza kazibuthe e-infrared.Ngemva kokuqhuma kwentaba-mlilo okungenalusizo, ngemva kwamashumi ezinkulungwane zeminyaka, Abantu baya ngokuya bethola ukubaluleka kwayo.Manje isinwebe izinkambu zayo zokufaka isicelo ukuze ifinyelele emikhakheni efana nezakhiwo, ukongiwa kwamanzi, ukugaya, okokuhlunga, amalahle esoso, ukunakekelwa kwezwe, ukutshala okungenamhlaba, kanye nemikhiqizo yokuhlobisa, idlala indima engenakushintshwa ezimbonini ezihlukahlukene.Izici ze-volcanic pumice (basalt) kanye nezakhiwo ezibonakalayo ze-volcanic rock biological filter materials.

Ukubukeka nokuma: Azikho izinhlayiya ezibukhali, ukumelana okuphansi nokugeleza kwamanzi, akulula ukuvinjwa, amanzi nomoya ohlukaniswe ngokulinganayo, indawo emagebhugebhu, isivinini esilengayo sefilimu esisheshayo, kanye nokungajwayeleki kakhulu ekuhlanganiseni amafilimu amancane ngesikhathi sokushaywa ngokuphindaphindiwe.

I-Porosity: Amatshe entaba-mlilo ngokwemvelo angamaselula futhi anezimbotshana, okuwenza abe indawo engcono kakhulu yokukhula yemiphakathi ephilayo.

Amandla omshini: Ngokomnyango kazwelonke wokuhlola ikhwalithi, ingu-5.08Mpa, osekufakazelwe ukuthi imelana nemiphumela yokugunda kwe-hydraulic yamandla ahlukene futhi inempilo ende yesevisi kunezinye izinto zokuhlunga.

Ukuminyana: Ukuminyana okumaphakathi, kulula ukukumisa phakathi nokuwashwa ngemuva ngaphandle kokuvuza kwempahla, okungagcina amandla futhi kunciphise ukusetshenziswa.

Ukuzinza kwamakhemikhali ezinto eziphilayo: Izinto ze-biofilter ye-volcanic rock azikwazi ukugqwala, azihlanganisi, futhi azibambi iqhaza ekuphenduleni kwamakhemikhali e-biofilm emvelweni.

Ugesi ongaphezulu kanye ne-hydrophilicity: Ingaphezulu le-volcanic rock biofilter ineshaja enhle, ehambisana nokukhula okungaguquki kwama-microorganisms.Ine-hydrophilicity eqinile, inani elikhulu le-biofilm enamathiselwe, kanye nesivinini esisheshayo.

Mayelana nomthelela kumsebenzi we-biofilm: Njengesithwali se-biofilm, imidiya ye-volcanic rock biofilter ayinayo ingozi futhi ayinawo umthelela ovimbela ama-microorganisms angaguquki, futhi ukuzijwayeza kufakazele ukuthi akuthinti umsebenzi wamagciwane.

Indima yamadwala entabamlilo 1: amanzi asebenzayo.Amatshe entabamlilo angakwazi ukusebenzisa ama-ion emanzini (ikakhulukazi ngokukhuphula okuqukethwe kwama-ion omoya-mpilo) futhi angakhulula kancane ama-A-ray kanye nemisebe ye-infrared, eyinzuzo kokubili izinhlanzi nakubantu.Umphumela wokubulala amagciwane wamadwala entaba-mlilo awunakushaywa indiva, futhi ukuwengeza ku-aquarium kungavimbela futhi kwelaphe iziguli ngempumelelo.

Iqhaza lamatshe entabamlilo ukusimamisa izinga lamanzi.

Lokhu kufaka phakathi izingxenye ezimbili: ukuzinza kwe-pH, engalungisa amanzi ane-asidi kakhulu noma ane-alkaline kakhulu ukuze asondele ngokuzenzakalelayo kokungathathi hlangothi.Ukuzinza kokuqukethwe kwamaminerali, amadwala entaba-mlilo anezici ezimbili zokukhulula izakhi zamaminerali kanye nokumunca ukungcola emanzini.Uma kukuncane kakhulu noma kuningi, ukukhululwa kwayo kanye nokukhangiswa kwayo kwenzeka.Ukuzinza kwevelu engu-PH yekhwalithi yamanzi ekuqaleni kwe-Arhat nangesikhathi sokufakwa umbala kubalulekile.

Umsebenzi wamadwala entaba-mlilo ukunxenxa umbala.

Amatshe entabamlilo agqamile futhi engokwemvelo ngombala.Zinomphumela ophawulekayo wokuheha umbala ezinhlanzini eziningi zokuhlobisa, njenge-Arhat, i-Red Horse, i-Parrot, i-Red Dragon, i-Sanhu Cichao, njalonjalo.Ikakhulukazi, i-Arhat inesici sokuthi umzimba wayo useduze nombala wezinto ezizungezile.Ubomvu bamatshe entaba-mlilo buzokwenza umbala we-Arhat ube bomvu kancane kancane.
