4: hom thiab RO kom muaj nuj nqis yog qhov tseem ceeb tshaj li thaj tsam ntawm daim nyias nyias thiab cov qauv tsim
Thaum tsim cov txheej txheem membrane, qee lub tuam txhab tau them nyiaj ntau heev rau seb cov membrane puas yog cov khoom siv txawv teb chaws, thiab tsis nkag siab qhov tseem ceeb ntawm kev tsim qauv. Qhov tseeb, kev ua tau zoo ntawm qee cov khoom siv hauv tsev ultrafiltration membranes tau mus txog lossis txawm tias mus txog qib siab thoob ntiaj teb, thiab tus nqi kev ua tau zoo tshaj li ntawm cov khoom siv txawv teb chaws. Qhov tsis ua haujlwm ntawm daim nyias nyias feem ntau yog los ntawm kev tsim engineering.
Ntau tus neeg siv tau them nyiaj ntau dua rau tus lej ntawmRO daim nyias nyiasnyob rau hauv daim nyias nyias reuse system, es tsis yog lub membrane cheeb tsam thiab system tsim ntawm lined enhanced PVDF membranes nyob rau hauv MBR thiab ultrafiltration modules nyob rau hauv pretreatment. Qhov tseeb, thaum lub mbr plus ro los yog uf plus ro ob chav membrane recycling txheej txheem raug saws,RO systemua haujlwm zoo, uas feem ntau cuam tshuam rau thaj chaw tsis txaus thiab tsis tsim nyog tsim ntawm pretreatment MBR lossis UF, uas ua rau cov dej ntws ntau dhau ntawm RO system. Qhov tseeb, tus nqi ntawm qee cov khoom siv membrane rau pretreatment yog siab dua li ntawm RO membrane, xws li MBR ca membrane, uas yog siab heev.
5: membrane technology yog omnipotent
Membrane thev naus laus zis yog chav tsev kho tshuab, uas muaj cov yam ntxwv ntawm qhov tsis muaj turbidity, decolorization, desalination thiab softening. Txawm li cas los xij, thaum kho cov dej khib nyiab hauv kev lag luam, cov tshuab membrane feem ntau yuav tsum tau ua ke nrog cov txheej txheem physicochemical thiab biochemical kho cov txheej txheem los muab kev ua si zoo dua rau qhov zoo ntawm kev kho mob siab heev. Tsis tas li ntawd, kev kho dej membrane feem ntau muaj teeb meem ntawm cov dej paug tawm. Nws kuj muaj cov kev xav tau ntawm kev txhawb nqa lwm yam thev naus laus zis, uas tsis yog txhua tus.
6: qhov ntau ntawm daim nyias nyias, qhov zoo dua
Nyob rau hauv ib tug tej yam ntau, nce tus naj npawb ntawm daim nyias nyias tuaj yeem txhim kho cov dej tsim kev nyab xeeb ntawm cov txheej txheem membrane thiab txo cov nqi ua haujlwm. Txawm li cas los xij, thaum tus naj npawb ntawm cov membranes nce mus rau ib qho twg, cov dej sib npaug ntawm lub tsev membrane txo qis, thiab cov dej ntws tawm ntawm daim nyias nyias ntawm qhov sib txawv ntawm cov dej ntws tawm qis dua qhov tseem ceeb, yog li cov khoom khib nyiab tso rau ntawm qhov chaw. daim nyias nyias tsis tuaj yeem muab tshem tawm, ua rau ua rau muaj kuab paug ntawm daim nyias nyias thiab txhaws thiab poob ntawm cov dej ntau lawm. Ntxiv mus, nrog kev nce ntawm cov membranes, qhov yuav tsum tau ntxuav cov dej ntim nce. Yog tias lub tshuab ntxhua khaub ncaws thiab cov cua compressed tsis tuaj yeem ua tau raws li qhov xav tau ntawm lub ntim ntim ntawm ib chav tsev membrane, nws yuav nyuaj rau ntxuav kom huv si, ua rau muaj kuab paug rau hauv daim nyias nyias thiab cuam tshuam rau nws cov dej ntau lawm, uas yog qhov tseem ceeb tshwj xeeb rau MBR lossis UF daim nyias nyias. Tsis tas li ntawd, thaum tus naj npawb ntawm cov membranes nce, cov peev txheej ib zaug thiab cov nqi qis ntawm cov txheej txheem yuav nce ntxiv.
7: RO daim nyias nyias yuav tsum siv cov ntaub thaiv npog
Raws li txoj cai, kev tiv thaiv fouling RO membrane yog qhov tsim nyog rau cov dej khib nyiab rov qab siv dua li cov pa RO membrane, tab sis kev xaiv ntawm cov ntaub thaiv fouling yog nyob ntawm nws cov txheej txheem tiv thaiv fouling. Muaj ob hom kev tiv thaiv kev ua qias tuaj RO daim nyias nyias: ib qho yog tias cov dej ntws ntawm cov membrane yog dav dua, uas tsis yooj yim rau kev thaiv thiab tiv thaiv kev ua qias tuaj. Hom membrane no feem ntau siv tau; Lwm qhov yog hloov kho RO membrane nto kom cov RO membrane tsis zoo, them zoo lossis hluav taws xob nruab nrab. Raws li lub hauv paus ntsiab lus uas cov khoom hluav taws xob tawm tsam ib leeg, cov pa phem nrog cov khoom tshwj xeeb tsis yooj yim rau tso rau ntawm daim nyias nyias, thiaj li ua tiav cov yam ntxwv ntawm kev ua qias tuaj. Kev tiv thaiv kev ua qias tuaj tom kawg yog nyob ntawm cov yam ntxwv ntawm cov dej zoo. Vim muaj ntau yam additives hauv kev luam ntawv thiab dyeing cov dej khib nyiab, nws yog ib qho tsim nyog los xaiv cov khoom tsim nyog los tiv thaiv cov pa phem raws li cov yam ntxwv ntawm RO system, txwv tsis pub nws yuav thim rov qab. Tsis tas li ntawd, hauv cov dej khib nyiab rov qab siv dua, vim tias RO daim nyias nyias yuav raug them sai sai los ntawm cov txheej txheem ntawm cov pa phem thiab homogenized, cov yam ntxwv hluav taws xob ntawm daim nyias nyias ntawm nws tus kheej tsis txawv, yog li nws qhov tseeb los tiv thaiv cov pa phem yuav tsum tau tham. Tus nqi ntawm cov pa phem RO membrane yog ntau dua li cov pa RO membrane, thiab muaj ob peb lub siab tsis tshua muaj siab los tiv thaiv cov pa phem, yog li nws tsis muaj qhov zoo ntawm cov dej khib nyiab rov qab siv dua.
