RO Membrane Rov Qab Osmosis rau Kev Haus Dej
RO membrane Taw qhia |
Cov thim rov qab osmosis membrane yog cov khoom siv hluavtaws semipermeable ua los ntawm cov roj ntsha uas muaj kev tiv thaiv kab mob uas muaj qee yam ntxwv thiab yog qhov tseem ceeb ntawm thim rov qab osmosis thev naus laus zis. Lub hauv paus ntsiab lus ntawm thim rov qab osmosis thev naus laus zis yog tshem tawm cov tshuaj thiab dej noo raws li lub siab osmotic ntawm kev daws, raws li qhov tseeb tias lwm yam tshuaj tsis tuaj yeem hla cov semipermeable membrane. Daim nyias nyias pore qhov loj ntawm qhov rov qab osmosis membrane yog qhov tsawg heev, yog li cov yaj ntsev, colloids, cov kab mob me me, cov teeb meem organic, thiab cov zoo li hauv dej tuaj yeem tshem tau zoo. Lub kaw lus muaj qhov zoo ntawm cov dej zoo, kev siv hluav taws xob tsawg, tsis muaj kuab paug, cov txheej txheem yooj yim thiab kev ua haujlwm yooj yim.
Rov Qab Osmosis Membrane yog qhov kev xaiv zoo tshaj plaws rau cov neeg siv dej haus, tus neeg sawv cev thiab cov neeg siv, nrog cov yam ntxwv raws li hauv qab no:
• Muaj kev nyab xeeb dua - RO dej huv ua yoog raws li Txoj Cai Tswj Kev Nyab Xeeb Ntawm Dej Haus thiab USEPA Cov Dej Haus.
• Cov saj zoo dua - RO daim nyias nyias tuaj yeem txav cov ntxhia ntau dua thiab lwm cov organic sib xyaw uas ua kom muaj ntxhiab tsw nyob hauv cov dej haus.
• Ua kom muaj kev noj qab haus huv ntau dua-RO daim nyias nyias tuaj yeem tsis kam lees cov kab mob thiab kab mob kom muaj dej huv rau haus thiab ua noj ua haus.

Rov qab osmosis membrane yog dav siv nyob rau hauv hluav taws xob fais fab, petrochemical, hlau, hluav taws xob, tshuaj, khoom noj khoom haus thiab dej haus, kev tiv thaiv nroog thiab kev tiv thaiv ib puag ncig, hauv seawater thiab brackish dej desalination, boiler pub dej, muaj dej ntshiab thiab hluav taws xob qib ultra-ntshiab dej npaj, haus cov dej ntshiab tsim, kev kho dej khib nyiab thiab cov txheej txheem sib cais tshwj xeeb ua lub luag haujlwm tseem ceeb.
Txoj ntsiab cai ua haujlwm |
Zaj duab xis uas xaiv rau cov khoom sib kis uas yog hu ua semi-permeable membrane. Feem ntau, cov yeeb yaj kiab uas tsuas tuaj yeem dhau los ntawm cov kuab tshuaj thiab tsis tuaj yeem dhau los ntawm cov solute yog hu ua qhov zoo tshaj plaws semipermeable membrane. Thaum tib lub ntim ntawm cov tshuaj sib tov (xws li dej tshiab) thiab cov tshuaj muaj zog (xws li dej ntsev) tau muab tso rau ntawm ob sab ntawm semipermeable membrane, cov kuab tshuaj nyob rau hauv cov tshuaj dilute yuav ib txwm dhau los ntawm semipermeable membrane thiab nthawv ntws mus rau sab ntawm cov tshuaj concentrated. Qhov tshwm sim no yog hu ua infiltration. Thaum cov permeation nce mus txog qhov sib npaug, qib ua kua rau ntawm qhov kev daws teeb meem sab yuav siab dua qib kua theem ntawm cov tshuaj tov, uas yog, qhov siab sib txawv yog tsim, thiab lub siab sib txawv yog lub siab osmotic. Qhov ntau ntawm lub siab osmotic nyob ntawm qhov xwm yeem ntawm qhov kev daws teeb meem, piv txwv li, ntawm hom, qhov siab thiab qhov kub ntawm cov tshuaj concentrated, tsis hais qhov xwm ntawm semipermeable membrane. Yog tias lub siab ntau dua osmotic lub siab yog thov rau sab ntawm cov kua uas muaj zog, cov kev taw qhia ntws ntawm cov kuab tshuaj yuav rov qab rau qhov kev taw qhia qub ntawm permeation, thiab cov ntws los ntawm cov tshuaj muaj zog rau ib sab ntawm cov tshuaj tov pib. Txoj kev no yog hu ua rov qab osmosis. Rov qab osmosis yog ib hom kev rov qab tsiv teb tsaws ntawm permeation. Nws yog qhov sib cais txoj kev sib cais uas cais kev sib cais nyob rau hauv txoj kev daws los ntawm cov kuab tshuaj los ntawm kev xaiv tuav ntawm lub semipermeable membrane nyob rau hauv siab tsav. Nws tau siv dav hauv ntau yam kua. Kev ua kom huv huv thiab kev kub siab, qhov piv txwv ntawm cov ntawv thov feem ntau yog kev siv thim rov qab osmosis thev naus laus zis kom tshem tawm cov inorganic ions, kab mob, kab mob, organic teeb meem thiab colloids hauv cov dej nyoos hauv cov txheej txheem kev kho dej kom tau cov dej ntshiab zoo.
