Cov Lus Qhia Txog Kev Siv Membrane RO: Cov Ntsiab Cai, Kev Xaiv & Cov Qauv
1. RO Membrane yog dab tsi?
Rov qab Osmosis (RO)yog ib qho txheej txheem uas thim rov qab osmosis ntuj. Hauv xwm, cov dej molecules txav mus los ntawm sab qis-concentration mus rau sab siab-concentration los ntawm lub semipermeable membrane. Hauv reverse osmosis, lub siab sab nraud yog siv los yuam cov dej molecules kom ntws mus rau hauv qhov kev taw qhia rov qab - los ntawm sab siab-concentration mus rau sab qis-concentration. Cov ntsev yaj, cov kab mob, cov kab mob, thiab cov organic teeb meem raug tsis lees paub los ntawm lub membrane thiab tso tawm ua concentrate.
Qhov pore loj ntawm RO membrane yog me heev - kwv yees li0.1 nanometer(ib feem lab ntawm cov plaub hau tib neeg) — muaj peev xwm tshem tawmtshaj 99%ntawm cov khoom khov uas yaj thiab feem ntau ntawm cov pa phem. Nws yog ib qho ntawm cov thev naus laus zis lim dej zoo tshaj plaws muaj.
2. Yuav ua li cas xaiv ib lub Commercial RO Membrane?
Lub hauv paus ntsiab lus: "Daim ntawv thov haum rau cov lus qhia tshwj xeeb" — daim membrane zoo tshaj plaws tsis yog qhov kim tshaj plaws lossis ua tau zoo tshaj plaws, tab sis qhov uas phim koj cov xwm txheej ua haujlwm zoo tshaj plaws.

- Kev ntws ntawm permeation: 0.8-1.2 m³/h ib lub ntsiab lus 8-nti
- Kev ua haujlwm siab: 69-1.0 MPa rau cov ntaub ntawv qis-siab, 5.5-8.4 MPa rau cov ntaub ntawv dej hiav txwv
3. Yuav Hloov Thaum Twg?
Hloov cov khoom membrane thaum cov cim hauv qab no tshwm sim:
- Kev poob qis ntawm cov kua dejCov dej ntws uas kho los ntawm qhov kub thiab txias poob qis dua 70-80% ntawm tus nqi pib
- Kev poob tsis lees txais: Kev ua tau zoo ntawm cov dej nkag mus rau hauv huab cua nce siab heev; kev tsis lees txais poob qis dua 95%
- Kev poob siab nce ntxiv: Qhov siab sib txawv nce ntau dua 15% siab dua tus nqi pib
- Kev ntxuav ntau zaus: Lub sijhawm ntxuav tshuaj luv dua mus txog tsawg dua 1 lub hlis
Lub neej ua haujlwm ib txwm muaj: Cov ntawv RO ua lag luam feem ntau kav ntev2-5 xyoos, nyob ntawm seb cov dej pub zoo thiab kev coj ua txij nkawm zoo li cas.
