Ua kom tiav Daim Ntawv Qhia rau RO Rov Qab Osmosis Membranes: Hloov Hloov, Txoj Cai Ua Haujlwm, thiab Tshem Tawm Ion

RO (Rov qab Osmosis) daim nyias nyias yog cov khoom tseem ceeb hauv cov dej huv huv, kev kho dej, kev siv dej haus, thiab dej hiav txwv desalination. Kev ua haujlwm ntawm RO system-nws cov dej zoo, kev ua haujlwm ruaj khov, thiab lub sijhawm ntev-tus nqi- feem ntau nyob ntawm daim nyias nyias. Cov lus nug feem ntau los ntawm cov neeg siv suav nrog:

1. Lub hauv paus ntsiab lus ua haujlwm ntawm RO membrane yog dab tsi?
2. Cov ions thiab cov kab mob twg tuaj yeem tshem tau?
3. Yuav tsum tau ntxuav los yog hloov RO membrane ntau npaum li cas?

Phau ntawv qhia no muab cov lus qhia dav dav los pab cov neeg siv kev paub txog kev txiav txim siab txog kev xaiv, kev ua haujlwm, thiab tswj RO daim nyias nyias.

Ib qho RO membrane yog ib qho khoom siv semipermeable membrane tsim los ua cov kab mob lom neeg, muab cov kev xaiv zoo heev. Qhov pore loj yog me me, feem ntau nyob ib ncig ntawm0.0001 microns, uas yog deb me dua cov kab mob, kab mob, thiab feem ntau yaj ntsev thiab cov organic molecules.

Qhov no ultra-filtration zoo tso cai rau RO daim nyias nyias kom zoo cais cov impurities yam tsis muaj theem hloov. Cov ntawv thov suav nrog:

• Cov dej haus hauv tsev thiab kev lag luam
• Industrial thiab ultrapure dej ntau lawm
• Kev kho mob, tshuaj, thiab electronics industries
• Dej hiav txwv thiab dej brackish desalination

Rov qab Osmosis (RO) yog asiab-tsav txheej txheem sib cais.

Nyob rau hauv ntuj osmosis, ib qho hnyav txav los ntawm qhov qis - kev sib xyaw ua ke mus rau qhov siab - kev sib xyaw kom txog thaum sib npaug. RO thim rov qab cov txheej txheem no:

• Siv siab rau sab pub ntau dua li osmotic siab
• Cov dej molecules raug yuam kom txav tawm tsam lub ntuj osmotic kev taw qhia los ntawm daim nyias nyias
• Cov kab mob paug, ntsev, thiab cov molecules loj tau khaws cia rau ntawm qhov siab -siab

Qhov no tsim ob kwj dej:

• Permeate (cov khoom siv dej): low-salinity, siab- dej purity
• Concentrate (brine): tov enriched nrog ntsev thiab impurities

Piv txwv li, nyob rau hauv dej hiav txwv desalination, qhov qis - sab siab tsim cov dej tshiab, thaum lub siab - sab siab tawm cov concentrated brine.

Ua tsaug rau nws qhov kev pom zoo heev, RO daim nyias nyias tuaj yeem tshem tawm ntau yam kab mob, nrog rau cov ntsev yaj, cov kab mob, thiab cov organic.

1. Dissolved ntsev thiab ions

2. Hnyav Hlau Ions

3. Microorganisms thiab Organic Pollutants

4.1 Hom Lifespan?

RO daim nyias nyias tsis muaj lub voj voog hloov ruaj khov; lifespan nyob ntawm cov dej zoo thiab kev ua haujlwm.

Raws li ib txwm muaj, RO membranes feem ntau kav ntev3-5 xyoos:

1. Pub dej raws li cov qauv
2. Pretreatment system yog ruaj khov
3. Kev kub siab, ntws, thiab cov nqi rov qab tswj tau

4.2 Yam Uas Ua Rau Lub Neej Ua Haujlwm?

Dej zoo: turbidity, SDI, organics, hlau / manganese

Pretreatment efficiency

Kev khiav hauj lwm tej yam kev mob: kev kub siab, siab heev rov qab

Kev Kho: Cov tshuaj ntxuav tu ib ntus (CIP)

4.3 Thaum twg Hloov?

Permeate ntws poob qis heev thiab kev tu tsis ua haujlwm

Ntsev tsis kam tus nqi txo

Kev khiav hauj lwm siab nce

Membrane puas los yog irreversible fouling

Kev ua haujlwm txuas ntxiv nyob rau hauv cov xwm txheej no cuam tshuam cov dej tsis zoo thiab nce nqi.
