Mererong ea ho hloekisa likhoerekhoere tsa diatomite, mekhoa e fapaneng e kang neutralization, flocculation, adsorption, sedimentation le filtration ea likhoerekhoere hangata li etsoa.Diatomitee na le litšobotsi tse ikhethang tsa 'mele le lik'hemik'hale. Diatomite e ka khothaletsa ho se nke lehlakore, flocculation, adsorption, sedimentation le filtration ea likhoerekhoere tse emisitsoeng ka mokhoa oa ho hloekisa likhoerekhoere ka mekhoa e fapaneng ea phetoho e kang pulverization, ho omisa, khetho le calcination. Mosebetsi.

Melao-motheo ea mantlha ea kalafo ea likhoerekhoere tsa diatomite:

1. Inter-particle dipole interaction: Bokaholimo ba likaroloana tsa diatomite bo qosoa 'me bo ka bapisa limolek'hule tsa dipolar (athomo) tsa mecha ea litaba ea polar, e leng se etsang hore limolek'hule tsena tsa dipole (athomo) li iketsetse maikutlo a unipolar ka holimo ho diatomite. Ha diatomite e kenngoa ka har'a likhoerekhoere, polarity ea pele e leka-lekaneng ea tsamaiso ea likhoerekhoere e robehile, 'me matla a dipole a sebetsa ho khothalletsa ho kopana ha likaroloana tsa colloidal le limolek'hule tsa polar (athomo) ka likhoerekhoere holim'a lefatše la diatomaceous ho theha agglomerations. Ho bonolo ho arola.

2. Flocculation: Flocculation ke ts'ebetso eo ka eona likaroloana tse nyane kapa li-agglomerate tsa likaroloana tse nyane li hlahisang li-flocs tse kholoanyane. Ho eketsa lefats'e le fetotsoeng la diatomaceous ho likhoerekhoere le ho etsa pherekano le kalafo ea botsofali ea tsamaiso ea ho qhalakanngoa ho ka etsa ka potlako lihlopha tse kholo tse tsitsitseng tsa lintho tse kotsi ka har'a likhoerekhoere. Ena ke katleho e kholo ea karohano e tiileng ea metsi a likhoerekhoere, e seng feela ho fokotsa litšenyehelo tsa ho laola tšilafalo, empa hape e ntlafatsa katleho ea karohano.

3. Adsorption: Adsorption ke phello e holimo. Bokaholimo ba lefats'e la diatomaceous le phatlalalitsoeng ho hoholo le na le matla a maholo a mahala mme le maemong a sa tsitsang haholo a thermodynamic, ka hona le na le tšekamelo ea ho khahla lintho tse ling ho fokotsa matla a holimo. Diatomaceous lefatše ka adsorb sehlopha flocculation, likokoana-hloko tse ling tsa baktheria le ultra-fine particulate taba ka likhoerekhoere ho ea ka hare le ka ntle holim'a 'mele oa diatom, ho etsa sehlopha se seholo sa phatsa e tsepamisitsoeng holim'a 'mele oa diatom. Ntle le moo, lefats'e la diatomaceous le lona ke sebaka se setle sa likokoana-hloko, ka hona ke sejari se setle sa li-microbial agents mererong ea kalafo ea likhoerekhoere tsa biochemical.

4. Filtration: Diatomite e batla e sa khonehe. Ka mor'a hore diatomite e itseng e fetotsoeng e eketsoe ka likhoerekhoere, e ka lula ka potlako ho theha bethe e tiileng ea porous filter, e loketseng bakeng sa ho tlosa litšila le ho tlosoa ha slag. The likhoerekhoere e tlhotliloeng ka filtara bethe e le hore livaerase tse khōlō, li-fungus, flocculation lihlopha, le likaroloana li kenoa le ho tlhotliloeng ka ntle tshebetsong. Letoto la lisebelisoa tsa kalafo ea likhoerekhoere tsa diatomite tse hlahisoang ke k'hamphani ea rona e sebelisang theknoloji e fetotsoeng li sebelisoa haholo kalafong ea likhoerekhoere tsa indasteri le litoropo. Basebedisi ba ka khetha teko e le 'ngoe kapa tse ngata tse kopantsoeng ho latela maemo a itseng ho finyella phello e lakatsehang.

Mobu o mosoeu o rehelletsoe ka lera le bosoeu bo bohlooho-tšoeu tlas'a lera la humus. E ajoa libakeng tse ka bochabela tsa lithaba le liphuleng tsa Leboea-bochabela ho Chaena, boemo ba leholimo bo mongobo, 'me mofuta oa limela ke limela tse metse ka metso e sa tebang. Pokello ea lintho tse phelang mobung e nyane ho feta ea mobu o motšo. Ka lebaka la ho bola ha lintho tse phelang hantle, hangata e na le litšobotsi tsa peatification. Likahare tsa lintho tse phelang ka holim'a mobu oa albic Ho fihlela ho 8-10%, sebopeho se ka tlas'a lesela la albic hangata se loam le letsopa le boima; lesela la albic le batla le le bobebe, 'me ho tsoa ha tšepe ho hlakile haholo. Morara oa letsopa ke haholo-holo hydromica e nang le kaolinite e nyane le ntho ea amorphous.

Lefatše la Diatomaceous le entsoe ka amorphous SiO2, 'me le na le palo e nyenyane ea Fe2O3, CaO, MgO, Al2O3 le litšila tse phelang. Lefatše la Diatomaceous hangata le mosehla o mosehla kapa o mosehla o bobebe, o bonolo, o porous le o bobebe. E sebelisoa hangata indastering e le lisebelisoa tsa ho kenya letsoho, lisebelisoa tsa filthara, li-filler, lisebelisoa tsa abrasive, lisebelisoa tse tala tsa khalase ea metsi, li-decolorants le li-catalyst carriers. Sebopeho se khethehileng sa porous sa lefats'e la tlhaho la diatomaceous se ka bonoa tlas'a microscope. Sebopeho sena sa microporous ke lebaka la litšobotsi tsa 'mele le lik'hemik'hale tsa lefats'e la diatomaceous. Karolo e ka sehloohong ea lefats'e la diatomaceous joalo ka sejari ke SiO2. Lefatše la Diatomaceous ka kakaretso le thehoa ke mesaletsa ea silicate ka mor'a lefu la algae e nang le sele e le 'ngoe ka kakaretso e bitsoang diatoms,' me mohloli oa eona ke SiO2 e nang le metsi amorphous. Diatoms ka metsing a hloekileng le Ho na le mefuta e mengata ea diatom e ka phelang metsing a letsoai. Ka kakaretso, li ka aroloa ka "central order" diatom le "plumbing order" diatom. Ka tatellano e 'ngoe le e' ngoe, ho na le "leloko" tse ngata, tse rarahaneng haholo. Karolo e ka sehloohong ea lefats'e la tlhaho la diatomaceous ke SiO2, tsa boleng bo phahameng li na le 'mala o mosoeu,' me litaba tsa SiO2 hangata li feta 70%. Li-diatom tsa monomer ha li na mebala ebile lia pepenene. 'Mala oa lefats'e la diatomaceous o itšetlehile ka liminerale tsa letsopa le lintho tse phelang. Sebopeho sa diatom mehloling e fapaneng ea liminerale e fapane. Diatomaceous Earth ke "fossilized diatomaceous earth deposit" e entsoeng ka mor'a lefu la semela se nang le sele e le 'ngoe se bitsoang diatom ka mor'a nako ea ho bokella lilemo tse ka bang 10,000 ho isa ho 20,000. Diatoms ke e 'ngoe ea li-protists tsa pele tse hlahang lefatšeng, tse phelang metsing a leoatle kapa metsing a letša. Ke diatom ena e fanang ka oksijene lefatšeng ka photosynthesis le ho khothalletsa tsoalo ea batho, liphoofolo le limela.
