Thuso ea sefahla sa diatomitee na le sebopeho se setle sa microporous, ts'ebetso ea adsorption le ts'ebetso e khahlanong le compression, e sa khoneng feela hore mokelikeli o sefiloeng o fumane tekanyo e ntle ea ho phalla, empa hape o hloekisa lihlahisoa tse ntle tse emisitsoeng ho netefatsa ho hlaka. Diatomaceous Earth ke polokelo ea mesaletsa ea li-diatom tsa khale tse nang le sele e le 'ngoe. Litšobotsi tsa eona: boima bo bobebe, porous, matla a phahameng, ho hanyetsa ho roala, ho kenya letsoho, ho kenya mocheso, adsorption le ho tlatsa le ts'ebetso e 'ngoe e babatsehang. Kajeno, Julian diatomite e tla tumisa several mekhoa e fapaneng ea ho sefa ea thuso ea filthara ea diatomite.

Sesebelisoa sa "diatomite filter" se ts'oara haholo-holo likaroloana tse tiileng tsa litšila tse emisitsoeng holim'a metsi le mocha ka mesebetsi e meraro ea ho hlahloba, phello e tebileng, le adsorption, e le ho finyella sepheo sa karohano ea metsi a tiileng.

1. Diatomite screening effect: Ena ke phello ea ho sefa holim'a metsi. Ha mokelikeli o phalla lefatšeng la diatomaceous, li-pores tsa lefats'e la diatomaceous li nyenyane ho feta boholo ba likaroloana tsa likaroloana tse sa hloekang, e le hore likaroloana tse sa hloekang li se ke tsa feta 'me li amoheloe. Phello e bitsoa "screening effect".

2. Phello e tebileng ea Diatomite: Phello e tebileng ke phello ea ho boloka ho hloekisa ho tebileng. Ka filtration e tebileng, mokhoa oa ho arohana o hlaha feela "ka hare" ho bohareng. Karolo ea likaroloana tse nyane tse sa hloekang tse kenang ka holim'a kaka ea filthara li koahetsoe ke diatomite. Mohaho o ka hare oa tortuous microporous le li-pores tse ntle ka hare ho kaka ea filter li thibetsoe. Likaroloana tse joalo hangata li nyane ho feta li-micropores tsa lefats'e la diatomaceous. Ha likaroloana li otla lebota la mocha, li ka 'na tsa tlohela ho phalla ha metsi. Leha ho le joalo, hore na e ka finyella sena ho itšetlehile ka ho leka-lekana ha matla a inertial le ho hanyetsa likaroloana. Thibelo ena le tlhahlobo li tšoana ka tlhaho, 'me ka bobeli ke tsa litlamorao tsa mochini. Bokhoni ba ho sefa likaroloana tse tiileng ha e le hantle bo amana feela le boholo le sebopeho sa likaroloana tse tiileng le li-pores.

3. Diatomite adsorption: The adsorption ha e le hantle e ka nkoa e le ho khahloa ke electrokinetic, eo haholo-holo e itšetlehileng ka thepa ea holim'a likaroloana tse tiileng le diatomite ka boeona. Boemo ba ntlha ea lefats'e la diatomaceous ha bo bobe, boleng bo felletseng bo boholo, 'me bo ka bapisa litefiso tse ntle. Ha likaroloana tse nyane ho feta li-pores tse ka hare tsa lefats'e la diatomaceous li thulana holim'a bokaholimo ba lefatše la porous diatomaceous, li hoheloa ke litefiso tsa motlakase. Ho boetse ho na le mofuta oa khoheli pakeng tsa likaroloana ho theha lihlopha le ho khomarela lefats'e la diatomaceous. Ka bobeli ke tsa adsorption, 'me adsorption e rarahane ho feta litlamorao tse peli tse fetileng. Ka kakaretso ho lumeloa hore lebaka leo ka lona likaroloana tse tiileng tse nyane ho feta bophara ba pore li ts'oaroang haholo-holo ka lebaka la: matla a intermolecular (hape a bitsoa van der Waals attraction), ho kenyelletsa le dipole tse sa feleng, dipole tse hlahisitsoeng, dipole tsa hang-hang le ho ba teng ha mokhoa o ka bang teng oa phapanyetsano ea Ion.
