Piav hom kev ua haujlwm ntawm Reverse Osmosis Dej Purifier

Rov qab osmosis dej purifiers feem ntau ntsia ib sab ntawm faucets. Ib daim nyias nyias uas xaiv rau cov tshuaj permeable yog hu ua semipermeable membrane. Feem ntau, ib daim nyias nyias uas tuaj yeem dhau los ntawm cov kuab tshuaj tab sis tsis yog cov kuab tshuaj yog hu ua ib qho zoo tagnrho semipermeable membrane.
Thaum tib lub ntim ntawm dilute tov thiab concentrated tov yog muab tso rau ntawm ob sab ntawm lub semipermeable membrane, nrog ib tug semipermeable membrane thaiv nruab nrab, cov kuab tshuaj nyob rau hauv lub dilute tov yuav lawm dhau los ntawm semipermeable membrane thiab ntws mus rau cov concentrated tov sab. Cov kua theem yuav siab dua cov kua theem ntawm cov kua dilute los ntawm ib tug tej qhov siab, tsim ib tug siab sib txawv thiab mus txog rau lub xeev ntawm osmotic equilibrium.
Lub siab sib txawv no yog osmotic siab. Qhov loj ntawm osmotic siab nyob ntawm seb hom kua concentrated, thiab cov concentration thiab kub tsis muaj dab tsi cuam tshuam nrog cov khoom ntawm semipermeable membrane. Qhov loj ntawm osmotic siab nyob ntawm cov khoom muaj txiaj ntsig ntawm cov tshuaj, uas yog, nws muaj feem xyuam rau hom, concentration thiab kub ntawm cov tshuaj thiab tsis muaj dab tsi cuam tshuam nrog cov khoom ntawm semipermeable membrane.
Yog hais tias lub siab ntau dua li osmotic siab yog siv rau ib sab ntawm cov tshuaj, cov kev taw qhia ntws ntawm cov kuab tshuaj yuav rov qab mus rau qhov qub osmosis kev taw qhia thiab pib ntws los ntawm cov concentrated tov mus rau dilute tov sab. Cov txheej txheem no hu ua rov qab osmosis. Los ntawm cov txheej txheem ntawm thim rov qab osmosis, dej tuaj yeem txav los ntawm kev daws teeb meem ntau dua mus rau cov tshuaj tsis muaj zog.
Txij li thaum inorganic ions, colloidal tshuaj thiab macromolecular solutes tsis tuaj yeem dhau los ntawm qhov rov qab osmosis daim nyias nyias, nyob rau hauv cov txheej txheem no, cov khoom tsis tsim nyog tau tso rau ntawm ib kawg ntawm cov tshuaj uas muaj siab concentration, thiab qhov kawg uas tsis muaj concentration yog cov kua purified tau.
