Kev sib cais-kua kua:
Kev sib cais ntawm cov kua dej yog cov txheej txheem ntawm kev sib cais cov khoom ntawm cov kua. Nws yog ib qho kev lag luam hauv ntau yam lag luam xws li tshuaj lom neeg, tshuaj, khoom noj thiab dej haus, kev kho dej, thiab kev tsuas. Lub hom phiaj ntawm kev sib cais no yog tshem tawm cov khoom tsis huv, rov qab cov khoom muaj txiaj ntsig, lossis qhia meej cov kua. Cov txheej txheem sib cais-kua tuaj yeem faib dav rau hauv kev pom, sedimentation, thiab centrifugation.
Lim:
Cov txheej txheem lub cev uas cov kua tau dhau los ntawm qhov nruab nrab lim uas cuam tshuam cov khoom siv, tso cai rau cov kua hla dhau.
Hom: Membrane lim, ntaub lim, xuab zeb lim, thiab ntawv lim.
Daim ntawv thov: Siv nyob rau hauv kev lag luam xws li dej purification, khoom noj khoom haus, thiab kev tsim tshuaj.
Sedimentation:
Cia siab rau lub ntiajteb txawj nqus kom cais cov khoom ntawm cov kua. Cov khib nyiab hnyav dua nyob hauv qab ntawm lub thawv, tso cai rau cov kua dej kom meej meej.
Daim Ntawv Thov: Cov nroj tsuag kho dej thiab hauv qee cov txheej txheem mining.
Centrifugation:
Siv lub zog centrifugal los cais cov khib nyiab los ntawm cov kua los ntawm kev sib tov sib xyaw ntawm kev kub ceev. Cov denser solids txav mus rau sab nraud, thaum cov kua tsawg dua nyob hauv qhov chaw.
Daim ntawv thov: Siv nyob rau hauv lub chaw soj nstuam rau cov qauv kev npaj, hauv kev lag luam khoom noj rau kev sib cais cov kua mis los ntawm cov mis nyuj, los yog hauv kev lag luam kws tshuaj rau kev sib cais ntawm cov ntshav plasma.
Centrifugal Lim:
Lub centrifugal lim (los yog lim centrifuge) yog ib qho khoom siv uas siv lub zog centrifugal los cais cov khoom ntawm cov kua, qhov tseem ceeb sib txuas nrog cov centrifugation. Nws ua haujlwm los ntawm kev sib tov ntawm cov khib nyiab thiab cov kua dej ntawm kev kub ceev hauv lub nruas rotating lossis chamber, qhov twg:
Cov khoom uas raug yuam tawm sab nraud vim yog lub zog centrifugal.
Cov kua (lossis filtrate) tseem nyob ntawm qhov chaw lossis dhau los ntawm cov ntawv lim dej.
Cov ntsiab lus tseem ceeb ntawm centrifugal lim:
Rotor lossis Nruas: Qhov sib hloov qhov twg qhov sib cais tshwm sim.
Filter Medium: Ib qho screen lossis daim nyias nyias uas tso cai rau cov kua hla dhau tab sis ua rau cov khoom sib txuas.
Pub Inlet: Qhov twg cov khoom sib xyaw ua kua yog nkag rau hauv lub lim.
Qhov hluav taws xob: Qhov twg cov kua sib cais (filtrate) tawm ntawm lub centrifuge.
Lub qhov hluav taws xob tawm: Qhov twg cov khoom sib cais tau tawm ntawm lub centrifuge tom qab txheej txheem.
Txoj Cai Ua Haujlwm:
Cov khoom sib tov-kua yog pub rau hauv lub centrifuge chamber.
Lub chamber yog spun sai, tsim lub zog centrifugal.
Cov khib nyiab hnyav dua raug yuam tawm sab nraud thiab sau rau ntawm qhov nruab nrab lim.
Cov kua, tam sim no tsis muaj cov khib nyiab, dhau los ntawm cov lim thiab tawm los ntawm qhov hluav taws xob lim.
Tom qab cov txheej txheem, cov khib nyiab tuaj yeem raug tshem tawm ntawm lub lim kom pov tseg lossis ua haujlwm ntxiv.
Daim ntawv thov ntawm Centrifugal Filtration:
Kev lag luam tshuaj: tshem tawm impurities los ntawm cov kua tshuaj los yog cais cov khoom los ntawm cov khoom.
Kev lag luam kws tshuaj: Rau cov txheej txheem purification, xws li cais cov tshuaj sib xyaw los ntawm cov tshuaj tiv thaiv sib tov.
Khoom noj khoom haus thiab dej haus: cais cov khoom seem ntawm cov kua (piv txwv li, hauv kev tsim cov roj, kua txiv hmab txiv ntoo, thiab syrups).
Kev Kho Dej: Siv rau kev tshem tawm hauv cov txheej txheem dej khib nyiab.
Centrifugal filtration yog qhov ua tau zoo dua li kev pom yooj yim, tshwj xeeb tshaj yog rau cov khoom zoo lossis thaum cov khib nyiab raug tshem tawm hauv cov kua dej uas muaj viscosity siab. Nws yog ib txoj hauv kev muaj zog rau kev lag luam loj-kua sib cais txheej txheem.
