Rov qab osmosis dej kho cov cuab yeej ua cov cuab yeej tshwj xeeb rau kev lim dej lim dej ntau lawm, siv cov txheej txheem sib kis ntawm rov qab osmosis membrane, los ntawm cov twj tso kua mis siab ntawm cov cuab yeej siv lub siab rau cov dej nyoos los ntawm rov qab osmosis membrane, yog li ntawd. cov dej molecules nyob rau hauv cov dej nyoos tuaj yeem permeated los ntawm daim nyias nyias thiab tawm. Txawm li cas los xij, lwm cov ntsev inorganic, microorganisms thiab cov organic teeb meem tsis tuaj yeem nkag mus rau qhov rov qab osmosis membrane vim kev cuam tshuam cov yam ntxwv ntawm cov tshuaj no, thiaj li tau txais cov dej ntshiab uas tsis yog-ionized.
Rov qab osmosis (RO) yog ib qho tseem ceeb ntawm cov tshuab sib cais membrane. Thaum siab osmotic siab dua li cov tshuaj, lwm yam tshuaj thiab dej raug tshem tawm ntawm lub semi-permeable membrane nyob ntawm lawv impenetrability.
Vim tias cov membrane aperture ntawm rov qab osmosis membrane yog me me (tsuas yog hais txog 10A), nws tuaj yeem tshem tawm cov ntsev yaj, colloid, kab mob, cov organic teeb meem, thiab lwm yam.
Nws muaj qhov zoo ntawm cov dej zoo, kev siv hluav taws xob tsawg, tsis muaj kuab paug, txheej txheem yooj yim thiab ua haujlwm yooj yim. Nws yog lub zog txuag tshaj plaws thiab yooj yim siv tshuab rau desalination ntawm seawater thiab brackish dej thiab npaj cov dej ntshiab.
Tam sim no, nws tau siv dav hauv tshuaj, hluav taws xob, tshuaj lom neeg, khoom noj khoom haus, dej hiav txwv desalination thiab ntau lwm yam lag luam.
RO system yuav tsum tau txais kev tswj hwm kev ua haujlwm tsis siv neeg raws li qib dej ntawm thawj lub tank desalting thiab cov dej tsim tawm. Yog tias tsim nyog pib, nres lossis hloov lub kaw lus, tus neeg teb xov tooj yuav tsum paub meej thiab hloov lub kaw lus manually. Kev tswj hwm ntawm RO system thiab kev tswj hwm ntawm tag nrho cov khoom siv tshuaj kho dej yog pom tau los ntawm kev tswj hwm (PLC) hauv chav tswj. Peb xaiv cov khoom siv tuaj txawv teb chaws nrog cov dej loj permeability, siab desalting tus nqi, tshuaj lom neeg ruaj khov, zoo tiv thaiv kev ua qias tuaj thiab zoo txhua yam muaj zog raws li cov dej tsis zoo. Peb tawm tswv yim qhov siab tshaj plaws membrane flux, tus nqi rov qab thiab qhov siab tshaj plaws ntawm cov dej membrane ntawm cov khoom siv membrane raws li cov dej tsis zoo thiab tus nqi SDI ntawm cov dej. Kev npaj thiab kev sib xyaw ua ke ntawm cov theem thiab ntu ntawm cov membrane modules yog txiav txim siab los ntawm cov dej zoo, tus nqi rov qab thiab dej tawm los.
RO yog cov khoom siv zoo tshaj plaws thiab cov khoom siv desalination hauv tsev thiab txawv teb chaws. Cov txheej txheem no tuaj yeem tshem tawm cov teeb meem organic, kab mob thiab kab mob, daim nyias nyias tuaj yeem ua haujlwm nyob rau hauv qhov chaw ua haujlwm tsis tshua muaj siab, thiaj li ua tiav kev txuag hluav taws xob, txo cov cuab yeej siv thiab cov nqi khiav lag luam, thiab ua kom tiav qhov zoo tshaj plaws ua ke ntawm dej permeability thiab desalinization.
