Amagama amasha okukhetha ama-diatomaceous earth kusuka kubakhi zokufiltera zemithambo.

Kungani ama-diatomaceous earth amashumi ayiphilisa ngokungafanele kusukela kubakhi zokufiltera zemithambo

Amathuba ase-DE asezinga zokusebenza ayinika umkhawulo wokusebenza kwezindawo zokususa izinto ezingaphansi kwezindawo zokusebenza ngoba izinto zazo zingahlinzeki ngokupheleleyo, futhi le nto iyasinda ukulinganisana okudingekayo kwezindawo zokuphatha izinto. Zihlanjwa kumaqandu amangalisayo, amafrustula ase-diatom ayahlukahluka kakhulu ngokwakho nokubude—kepha ukuphatha okujwayelekile kukhombisa kuphela ukugcina kwezinye izinyathelo zokuphatha izinto, okungabikho ukulinganisana kwezinye izinyathelo. Le nkimbinkimbi iyasinda ubunzima bokugcina kwezinye izinyathelo: kunezinye izinyathelo ziyadlula ngokushesha, zisondla ukudlula kwezinye izinto, futhi kunezinye izinyathelo ziyagcinwa ngokushesha futhi zisondla ukulanda. Umhlango wezindawo zokusebenza wabonisa ukuthi i-DE esingaphansi kwezindawo zokusebenza ingalibeka ukulanda ngokupheleleyo nge-30% ngeminyaka eyi-200 yokuqala yokusebenza ngoba kuyadlula amaphakathi amancane futhi kuyasondla isikhundla (Inqaku Yokulinganisa Kwizindawo Zokusebenza 2022).

Ukubhalwa kwezinkulungwane kufaka isibonelo esishisiseyo esinye. Ukubhalwa kwezinkulungwane zokuphatha, ukubhalwa kwezinkulungwane zokuphatha, nokubhalwa kwe-iron oxide kushintsha ngosuku ngosuku emaphakathini—kubangela ukuthi izinkulungwane zokuphatha zizoba zingafanani, futhi ukuthi ukuthakazelwa kwesithakazelo kushintshwa ngokungafanele. Lokhu kuhlela ukuthi ukuthakazelwa kwezinkulungwane kushintshwa ngokungafanele, kubangela ukuthi abasebenzi bokuphatha baya kuzihlela ukuthi bakhetha ukugcina isikhundla sokusebenza noma bakhetha ukuthi bavule amagap emphakathi yezinhlobo zokusebenza nezinhlobo zokusebenza. Lokhu kungahleli kusenqumeni yezindawo ezinamakhulu yokuphatha izinkulungwane, izinkulungwane zokuphatha, noma izinkulungwane zokuphatha. Ekupheleni, i-DE eyenzelwe ngokujwayelekile iyabuyela ukuthi ukuthakazelwa kwezinkulungwane kubuyela kumashini yokuthakazelwa—futhi i-DE eyenzelwe ngokujwayelekile iyabuyela ukuthi ukuthakazelwa kubuyela kumsebenzi wokuphatha.

Ukuthi i-Diatomaceous Earth eyenzelwe ngokujwayelekile iyakhangelisa ukuthakazelwa nokuthakazelwa kwezinkulungwane

Abaholi bokuphatha kwezindustria zibona ngokuthula ukuthi i-diatomaceous earth engenakwenzeka kungasebenza kahle kusukela ekutholeni kwemithombo yezindlela zokusebenza nekubonisa ukuthi kuyisikhathi esihlukene. Amagradi ayesikriniwe ngokuchaza amagradi ayezifundwa ngokuphelele aqinisekisa izinto ezimbili ezingaphambili: isimo sesandla sokuphatha kanye nokufunda kwezinkulungwane. Uma lezi ziqinisekiswa kahle, amagradi okuphatha ayenziwe ngokuchaza ukuthi asebenze ngokuphelele kuzo zizindlela zokusebenza—kuvuselela ubukhulu, kugcina isikhathi sokusebenza, nokubonisa ukuthi umsindo wokuphatha uyisikhathi esihlukene.

Isimo sesandla sokuphatha esichazwe ngokuphelele ukuthi sibeke isikhathi esihlukene phakathi kwezindlela zokusebenza nekubonisa ukuthi kuyisikhathi esihlukene

Umkhukhu wemithambo yomkhakha we-DE uyasebenza njengokuphatha okuthile, apho ukuthi umkhakha uphatha ngokuphelele kuyaphendula kubinkulu bemithambo, ifomu yabo, nokuphelele kwezifomu. Ukuphelele kwezilinganiso zemithambo ezincinci, okwenzelwe ngokuzimisa, kusinika ukuthi umkhakha uqondile, ubungakanani obuncinci, nokuthi ubungakanani obuncinci. Imithambo encinci ibeka ubunzima obuphelele ngokuphatha amasimbi angaphezulu kwe-1 mikromitha; isilinganiso esisodwa semithambo encane kusinika ubungakanani. Ngaphandle kwezilinganiso ezingaphezulu nezizimisekile—ezisika ukuthi umkhakha ushwele ngokungafanele nokuthi ubunzima buphakanyiswe ngokungafanele—izilungiselelo zokuzimisa zisika ukuthi ipresha yekhanda yokuqondile iyasibonisa ubungakanani obuphelele, nokuthi ubunzima buphakanyiswe ngokuphelele, futhi kusho ukuthi ubunzima buphakanyiswe ngaphezu kwe-0.5 NTU nangona kusebenzisa ngokuphelele. Lokhu kusinika ubunzima obuphelele kwezikhathi zokusebenza, nokuthi ukubuyela emva kufutshane—loba izindlela ezibalulekile kumasevisi ayo amaningi kwezindlu zokwenza amazibulo nezindlu zokwenza izinhlayizo zokulwa.

Ukuchitha okuzimiselwe ukuthi kubhekiswe ubungakanani, ubukhulu, nokuthi kubhekiswe ukuthi kungabikho ukuthi kuhlwa ngokungafanele

Ukuphakamisa kususa kubuyisa isithembiso sesilika se-diatomaceous earth. Ngokusebenzisa ngokucophelela ubunzima bezindawo, isikhathi sokuhlala, nokwakhiwa kwezinye izinhlobo zezinhlobo, abaproducer bakhulisa ukulinganisa okuhle phakathi kwezinhlobo zokuphakamisa, ubukhulu bekuphakamisa, nobukhulu bekuphakamisa kwezinhlobo zokuphakamisa. Ithabuli elandelayo ilinganisa ukuguqula kwezinhlobo zokuphakamisa ngokugcina izikhathi zokuphakamisa:

Amathuba okukhanyisa kwe-flux, ngokomfanekiso, ukusintela amaphakathi we-diatom kancane ukuze kungavunyelwe ukugqibela kwemithombo yokuqhubeka—ngaphandle kokugcina umkhawulo wemicro-porosity ofanekayo kubalulekile ukususa amaphakathi amancane. Ukuphakamisa ukuthi kuyinkulu kunciphisa ukusebenzisa imidiya: kuncane amaphakathi akhuphuka futhi ayihlambulula umthombo wokufiltra, ukunciphisa ukuthabatha isitha futhi izindlela zokubuyela emva. Ukuthabatha kahle kwe-attrition kuvumela ukuthi umthombo uzobuyiselwa ngokuphelele ngeminyaka yokuqhubeka ngaphambi kokubuyela imidiya, ukuvumela ukusebenzisa kabanzi ngaphambi kokubuyela imidiya. Lezi zimbono ezisondela kakhulu zinika umsebenzi owodwa noma wokuphinda-phinda, okungasemthombweni wokusebenza kwe-DE esingasho isibonelo sokuzikhipha ngokuphelele.

Ukuchaza kwezinto zempilo: Ukuvumela ukusebenza kwe-Diatomaceous Earth ekhethwe ngokwesifundo kwezifiltri zemithombo yezindlu zokudla

Kwisikhundla sesidlo, ukuguqula kwe-diatomaceous earth esihlanganisiwe ngokupheleleyo kusinika iziphumo ezibonakalayo zokusebenza. Umsebenzisi wemiyalelo yefuriti wabeka ubukhulu besifunda sokugcina ngokuphela kwe-22% ngaphandle kokubeka ubukhulu besifunda sokugcina ngaphezulu kwe-0.5 NTU emva kokuguqula isigaba esingafanele ngokwezinye ezihlanganisiwe ngokupheleleyo (Ukuchaza Kwesikhundla Sokugcina 2023). Ngokufanayo, umkhakha omkhulu wemiyalelo wabeka ubukhulu besifunda sokugcina ngokuphela kwe-15%—futhi wabeka ubude lwesikhathi sokusebenza ngamahoura amathathu—ngokusebenzisa ukugcina okuhlanganisiwe ngokupheleleyo nokuhlanganisa izinkomo zezinto. Lezi ziziphumo zibeka ubukhulu besifunda sokugcina ngokuphela ngokucisha ubukhulu besifunda sokugcina futhi ukucisha isikhathi sokungasebenzi ngokugcina noma ukuguqula.

Ngaphandle kwezimali, i-DE eyenziwa ngokuhambisana ngenkathi yezifundo eziphakeme kungahlinzeka ukuthi iphumelele kwezindlela zokusebenza. Ukulungisa isimo sesikhala nesibonelo sokubhala kusenza umkhakha ukuba ubheke kakhulu ekupheleni kwemithombo yokuqondisa ukuthi kuyinto engeyona isikhala esingaphansi kodwa yilokho okuphakeme nokwenzeka kakhulu ekufiltratheni. Lokhu kusenza ukuthi isiphumo sibe yilokho ocacile, kuncishwa ukugcina kwezinto ezingavumelekile, nokuphucuka kwezindlela zokuphatha izinto ngokuphelele. Lokhu kubhekisana nokuthi ukuthi ukuthi kuzoba yilokho okuphakeme kwezifundo kubhekisana nokuthi kuzoba yilokho okuphakeme kwezindlela zokusebenza ngosuku sonke—kubonisa ngani i-DE eyenziwa ngokuhambisana ngenkathi yezifundo ibe yilokho okuphakeme kwezindlela zokufiltratha izinkambo zomnotho.

Isikhombisi Sokuqala

I-DE (diatomaceous earth) iyasebenzisa kanjani ekufiltratheni yezindustria?

I-DE isebenzisa njengokufuna ukufiltratha ekuphatha kwezindustria. Iyasebenza ukuthi iforme amakhanda okufiltratha okuyizinto ezingafihliki, ukuze kuvumelwe ukuthi izinkambo ziyacacile futhi ukuthi ukufiltratha kwenza ngokuphelele.

Kungani i-DE eyenzelwe ngokujwayelekile ayisebenzi kahle ekufiltratheni?

Izinhlobo zesifunda sokugcina esingafanele ziyasihlukaniswa ngokuhlanganisa ubude bokuphakama kanye nokuhlanganisa izinhlobo zezinto, okuzosindisa ubukhulu besifunda sokugcina, ukunciphisa ubude bokusebenza, futhi ukuphatha ubukhulu besifunda sokugcina.

Izinhlobo zesifunda sokugcina esihlanganisiwe ngokupheleleyo zinakho ziziphumo ziphi?

Amathuba okugcina amaphuzu ayo aqondwa ngokupheleleyo aqondwa ngokupheleleyo kwe-DE akunceda ukuthi isifunda sesifunda sisebenze ngokupheleleyo ngokunika umphumela wokugcina amaphuzu okuhambisana, ukugcina okupheleleyo kwe-calcination ukuze kube lula ukugcina, ubukhulu, nokuphila kakhulu kwesifunda.

Ukucalcination kwenza kanjani ukuthintana nezinkinga zesi-DE?

Ukucalcination kubuyekeza isithembiso se-siliceous se-DE, kuvuselela ukugcina, ubukhulu be-mechanical, nokuzimisa ukuthintana kwezinkomo, okuvuselela ukuthintana kwezinkinga zokugcina.

Izindustri ziphi ezenza isiphumo esikhulu kuma-grades ayo aqondwa ngokupheleleyo kwe-diatomaceous earth?

Izindustri njengezindustri zokwenza izinkampani zemithwalo, ukwenza izinkampani zezinto zokushaya, nezindustri zemithwalo yezempilo zenza isiphumo esikhulu ngokuthi zinikeza ukuthi isifunda sisebenze ngokupheleleyo, ukuthi isifunda sibe lula, nokuncima kwezinto ezizwakalayo ezinikezwa ngama-grades ayo aqondwa ngokupheleleyo kwe-DE.
