Thaum xaiv lub tshuab lim dej hauv qab lub dab dej, muaj ntau yam uas yuav tsum xav txog:

1. **Hom Tshuab Lim Dej:**
– Muaj ntau hom muaj xws li Microfiltration (MF), Ultrafiltration (UF), Nanofiltration (NF), thiab Reverse Osmosis (RO). Thaum xaiv, xav txog cov thev naus laus zis lim, qhov ua haujlwm ntawm lub lim, qhov yooj yim ntawm kev hloov lub thawv, lub neej ntev, thiab tus nqi hloov.

2. **Kev lim dej me me (MF):**
– Feem ntau qhov kev lim dej raug yog txij li 0.1 txog 50 microns. Cov hom lim dej feem ntau suav nrog PP lim cartridges, activated carbon lim cartridges, thiab ceramic lim cartridges. Siv rau kev lim dej ntxhib, tshem tawm cov khoom loj xws li cov av nkos thiab xeb.

- Qhov tsis zoo suav nrog tsis muaj peev xwm tshem tawm cov tshuaj lom neeg xws li cov kab mob, tsis muaj peev xwm ntxuav cov lim dej (feem ntau pov tseg), thiab yuav tsum tau hloov pauv ntau zaus.

3. **Kev lim dej ultrafiltration (UF):**
- Kev lim dej kom raug yog txij li 0.001 txog 0.1 microns. Siv cov thev naus laus zis sib cais membrane kom tshem tawm xeb, av qias neeg, colloids, cov kab mob, thiab cov organic loj.

- Cov txiaj ntsig suav nrog kev rov qab tau dej ntau, yooj yim ntxuav thiab ntxuav rov qab, lub neej ntev, thiab tus nqi ua haujlwm qis.

4. **Nanofiltration (NF):**
- Kev lim dej kom raug yog nyob nruab nrab ntawm UF thiab RO. Yuav tsum muaj hluav taws xob thiab siab rau kev siv tshuab cais daim nyias nyias. Yuav tshem tau cov calcium thiab magnesium ions tab sis tej zaum yuav tsis tshem tau qee cov ions phem tag nrho.

- Qhov tsis zoo suav nrog qhov txo qis ntawm kev rov qab tau dej thiab tsis muaj peev xwm lim qee yam tshuaj lom.

5. **Kev Rov Qab Osmosis (RO):**
- Kev lim dej siab tshaj plaws txog li 0.0001 microns. Muaj peev xwm lim yuav luag txhua yam tsis huv xws li cov kab mob, cov kab mob, cov hlau hnyav, thiab cov tshuaj tua kab mob.

- Cov txiaj ntsig suav nrog kev ua kom dej ntshiab sai, lub zog kho tshuab siab, lub neej ntev, thiab kev kam rau cov tshuaj lom neeg thiab cov kab mob hauv lub cev.

Hais txog kev muaj peev xwm lim dej, qhov kev qeb duas feem ntau yog Microfiltration > Ultrafiltration > Nanofiltration > Reverse Osmosis. Ob qho tib si Ultrafiltration thiab Reverse Osmosis yog cov kev xaiv tsim nyog nyob ntawm seb koj nyiam dab tsi. Ultrafiltration yooj yim thiab pheej yig tab sis tsis tuaj yeem haus ncaj qha. Reverse Osmosis yooj yim rau cov dej zoo, xws li ua tshuaj yej lossis kas fes, tab sis tej zaum yuav xav tau cov kauj ruam ntxiv rau kev haus. Nws raug pom zoo kom xaiv raws li koj cov kev xav tau thiab kev nyiam tshwj xeeb.
