Membrane lim txheej txheem yog ib qho zoo, txais txheej txheem rau kev kuaj cov kua dej kuaj rau microbiological paug. Nws koom nrog kev npaj tsawg dua li ntau txoj hauv kev ib txwm muaj, thiab yog ib qho ntawm ob peb txoj hauv kev uas yuav tso cai rau kev rho tawm thiab suav cov kab mob.
Tsis tas li ntawd, lub filtration membrane yog dab tsi?
Membrane Lim . A daim nyias nyias yog ib txheej nyias ntawm cov khoom siv semi-permeable uas cais cov tshuaj thaum lub zog tsav tsheb siv thoob plaws daim nyias nyias.
Qhov thib ob, dab tsi yog cov khoom siv ntawm cov membrane pom? Membrane Lim . Membrane Lim : Cov txheej txheem ntawm membrane lim siv lub zog los quab yuam cov kua nqaws, xws li dej, los ntawm ib qho permeable (porous) daim nyias nyias txhawm rau cais cov teeb meem tshem tawm ntawm cov kua thiab soluble cov khoom.
Kuj kom paub, qhov zoo ntawm cov txheej txheem membrane filtration yog dab tsi?
Qhov zoo ntawm MF Cov txheej txheem Tso cai rau kev sim ntawm cov qauv loj loj. Txo lub sij hawm npaj raws li piv rau ntau txoj hauv kev. Tso cai cais tawm thiab suav ntawm cov kab mob sib cais ntawm cov kab mob. Muab cov ntaub ntawv muaj los yog tsis muaj nyob hauv 24 teev.
Puas yog cov txheej txheem lim membrane zoo lossis ntau yam piav qhia?
A membrane lim (MF) txoj kev tau soj ntsuam rau nws haum rau zoo thiab kom muaj nuj nqis Kev soj ntsuam ntawm Cronobacteria spp. Tsis tas li ntawd, txoj kev tshawb fawb tau lees paub qhov muaj peev xwm ntawm kev siv tag nrho cov coliform raws li qhov taw qhia ntawm kev sib kis ntawm Cronobacter spp. Hauv cov dej haus, thiab qhov tau txais qhov tseeb qhov zoo yog 96%.
