Lub Reverse Osmosis (RO) Dej System yog lub tshuab ua kom huv dej uas siv lub semi-permeable membrane kom tshem tawm ntau yam kab mob los ntawm dej los ntawm kev siv lub zog los kov yeej lub ntuj osmotic siab.
Nws ua haujlwm li cas
Nyob rau hauv ntuj osmosis, dej ntws los ntawm ib daim nyias nyias los ntawm ib tug tsawg concentrated tov rau ib tug ntau concentrated. Rov qab osmosis thim rov qab cov txheej txheem no:
1. Pre-filtration: Dej dhau los ntawm sediment thiab carbon lim kom tshem tawm cov chlorine, sediment, thiab cov khoom loj uas tuaj yeem ua rau RO daim nyias nyias.
2. Pressurization: Lub siab - lub twj tso kua mis siab quab yuam dej (feem ntau yog 4-15 bar, nyob ntawm daim ntawv thov) tawm tsam lub semi-permeable membrane
Kev sib cais: Lub membrane tso cai rau cov dej molecules hla thaum thaiv cov ntsev yaj, cov zaub mov, kab mob, kab mob, thiab lwm yam kab mob.
3. Khoom & Tsis Txaus Siab:
* Permeate (purified dej) ntws los ntawm daim nyias nyias
* Concentrate (brine / tsis lees paub) nqa cov kab mob tsis pom zoo tawm mus
Dab tsi RO tshem tawm
| Hom kab mob | Piv txwv |
| Dissolved ntsev | Sodium, calcium, magnesium, chloride, sulfate |
| Cov hlau hnyav | Lead, arsenic, mercury, chromium |
| Cov kab mob | Kab mob, kab mob, protozoa |
| Organic compounds | Tshuaj tua kab, tshuaj, VOCs |
| Lwm yam | Nitrates, fluoride, radium, asbestos |
Cov ntawv thov siv
* Kev haus dej kom huv (chaw nyob thiab kev lag luam)
* Desalination ntawm seawater thiab dej brackish
* Cov txheej txheem dej (boiler pub, electronics manufacturing, pharmaceuticals)
* Cov dej khib nyiab rov siv dua thiab rov siv dua
* Kev ua zaub mov thiab dej haus
Cov ntsiab lus tseem ceeb
* RO membrane (nyias-film composite, kauv-mob los yog hollow-fiber)
* Siab- lub twj tso kua mis siab
* Pre-filters (sediment, activated carbon)
* Tshaj tawm - lim (polishing carbon lim, UV sterilization)
* Cia tank (rau cov kab ke hauv tsev)
* Flow restrictor thiab ntws kab (kom tswj tau lub siab thiab dej kom zoo)
Qhov Zoo & Kev Txwv
| Qhov zoo | Kev txwv |
| Tshem tawm txog li 99% ntawm cov kab mob sib kis | Tsim cov dej khib nyiab (feem ntau 1: 1 txog 1: 4 permeate - rau - tsis lees txais piv) |
| Tsis muaj tshuaj yuav tsum tau ua kom huv | Yuav tsum muaj hluav taws xob thiab dej siab |
| Compact thiab scalable | Membranes tuaj yeem foul lossis nplai yam tsis muaj kev kho kom raug |
| Tsim kom muaj dej zoo ib yam | Tus nqi qis qis; feem ntau xav tau lub tank cia |
RO yog ib qho ntawm cov dej lim dej zoo tshaj plaws uas muaj thiab feem ntau ua ke nrog lwm cov txheej txheem kho mob (xws li ultrafiltration, ion exchange, lossis UV) kom ua tiav cov hom phiaj dej zoo.
