Decantation yog ua raws li sedimentation . Decantation yog tus txheej txheem uas cov kua sedimented yog cais los ntawm pouring nws hauv lwm lub thawv qeeb heev yam tsis muaj kev cuam tshuam cov teeb tsa sediments nyob rau hauv qab ntawm lub thawv. Sedimentation yog tus txheej txheem ntawm kev daws ntawm hnyav insoluble impurities.

Yog li ntawd, dab tsi yog sedimentation thiab decantation?

Sedimentation txhais tau tias yog cov txheej txheem sib cais uas cov khoom sib cais los ntawm cov kua. Tag nrho cov khib nyiab nyob rau hauv qab ntawm lub beaker thiab nyob rau sab saum toj, ib tug ntshiab txheej ntawm cov kua yog tau. Decantation txhais tau tias yog cov txheej txheem sib cais uas ob cov kua dej tsis sib haum sib cais.

Tsis tas li ntawd, dab tsi yog hu ua decantation? Decantation yog txheej txheem los cais cov sib tov los ntawm kev tshem tawm cov txheej txheem ua kua uas tsis muaj precipitate, lossis cov khib nyiab tso los ntawm kev daws teeb meem. Lub hom phiaj tej zaum yuav yog kom tau ib qho decant (kua dawb los ntawm particulates) los yog kom rov qab tau cov precipitate.

Ntawm no, qhov txawv ntawm sedimentation thiab filtration yog dab tsi?

Sedimentation tshwm sim thaum cov khoom tshem tawm loj txaus los khom rau hauv qab ntawm lub nkoj hauv qab lawv qhov hnyav. Lim ua haujlwm ntawm txawv nyob rau hauv particle loj nruab nrab cov kua me me los yog roj molecules thiab cov khoom loj dua.

Cov piv txwv ntawm sedimentation yog dab tsi?

Rau piv txwv , xuab zeb thiab silt yuav nqa tau nyob rau hauv ncua kev kawm ntawv nyob rau hauv dej dej thiab mus txog lub hiav txwv txaj tso los ntawm sedimentation.
