Rov qab osmosis dej kho cov cuab yeejfeem ntau muaj peb qhov chaw: cov dej nyoos ua ntej ua ntej, rov qab osmosis purification system, thiab ultra-purification tom qab kho qhov system. Lub hom phiaj ntawm pretreatment yog ua kom cov dej nyoos ua tau raws li cov dej nkag ntawm qhov rov qab osmosis membrane cais module, thiab kom ntseeg tau tias kev ua haujlwm ruaj khov ntawm qhov rov qab osmosis purification system.
Qhov rov qab osmosis membrane system yog qhov kev lag luam zoo tshaj plaws thiab ua kom huv huv kom tshem tawm ntau dua 98% ntawm ions, organic teeb meem thiab 100% ntawm cov kab mob (kev xav) hauv cov dej nyoos ntawm ib zaug. Lub ultra-purification tom qab kho qhov system ntxiv tshem tawm impurities xws li kab ions thiab cov organic teeb meem nyob rau hauv rov qab osmosis cov dej ntshiab los ntawm ntau yam kev siv thev naus laus zis kom ua tau raws li qhov kawg dej zoo ntsuas qhov yuav tsum tau ua rau ntau lub hom phiaj.
Raw dej pretreatment system ntawm me me rov qab osmosis dej ntshiab tshuab: Tom qab cov dej nyoos dhau los ntawm cov PP lim caij (sand rod filter), activated carbon unit, dej softener unit thiab lwm yam pretreatment systems, tshem tawm cov teeb meem (particulate teeb meem), colloid, organic teeb meem, hardness, cov ntsiab lus ntawm impurities xws li microorganisms yog heev txo, thiaj li yuav txo tau cov txheej txheem load ntawm lub tom ntej osmosis rov qab, hluav taws xob desalination thiab lwm yam txheej txheem, thiab mus cuag nws cov kev pab cuam lub neej.
Lub membrane yog kho nrog enzyme detergent, uas yog tshwj xeeb tshaj yog zoo rau cov organic kuab paug, tshwj xeeb tshaj yog rau cov protein, roj thiab lwm yam organic kuab paug. Cov nyhuv tu yuav zoo dua yog tias nws nyob ntawm 50 txog 60 degrees. Feem ntau, nws yuav khiav rau kaum hnub lossis ib nrab ib hlis. Tom qab ntawd, daim nyias nyias raug ntxuav ib zaug ntawm qhov tsis tshua muaj siab nrog 1% enzyme-ntxiv detergent. Txij li thaum lub concentration ntawm enzyme-ntxiv detergent yog tsawg, lub immersion lub sij hawm yuav tsum tau ntev dua. Hauv cov tshuaj citric acid, daim nyias nyias yog ntxuav tsis tu ncua los yog cyclically nrog 1% mus rau 2% citric acid aqueous tov nyob rau hauv lub siab los yog tsis tshua muaj siab. Txoj kev no muaj kev tu kom zoo ntawm Fe (OH) 3 cov pa phem.
Cov saum toj no yog kev paub txog me me rov qab osmosis dej purifiers. Piv nrog rau cov dej purifiers hauv tsev, me me rov qab osmosis dej purifiers muaj zog dua thiab tuaj yeem siv tau ntau qhov chaw. Cov dej rov qab osmosis me me tuaj yeem ua tau raws li qhov xav tau sib txawv. Cov dej kom zoo ntawm lub hom phiaj pab peb kom ntxuav cov dej tsis huv. Cov nyhuv dej purification yog pom tseeb heev. Nws tau nyiam ntau tus neeg' kev mloog thiab kev lees paub. Nws yog ib qho khoom siv dej purification zoo heev.
