Rov Qab Osmosis Txheej Txheem:
Cov dej tsis huv → Lub tshuab nqus dej → Cov tshuab lim tawm ntau dhau → Lub lim dej zoo → Cov tshuab lim dej (xaiv tau) filter Lub taub lim dej → Lub siab lim dej → Lub siab thim rov qab osmosis → kev kho PH → Lub taub lim dej → Lub taub tso dej → Cov dej lim → Cov ntxaij lim dej filter Cov qhov dej lim Cov.
Thib Ob Rov Qab Osmosis Txheej Txheem:
Cov dej tsis huv → Lub tshuab nqus dej → Tshaj tawm cov lim dej → Cov lim dej nquag → Lub tshuab lim dej (xaiv tau) filter Lub taub lim dej → Lub taub tso ntshav siab → Lub siab thim rov qab osmosis → kev kho PH lub cev tank Lub tank dej → Thim rov qab osmosis (rov qab osmosis membrane nrog kev zoo ntawm saum npoo) tank Lub taub lim dej → Lub taub dej → Tso tawm → Muab tshuaj ntxiv → Cov lim dej me me → Cov qhov tso pa tawm.

Thawj theem pretreatment. (Xuab zeb lim)

Kev siv ntau cov dej nruab nrab quartz xuab zeb lim, lub hom phiaj tseem ceeb yog tshem tawm cov dej muaj cov kev tso pa, manganese, xeb, cov khoom siv colloid, lub tshuab tsis ua haujlwm, kev txwv tsis pub khoom thiab lwm yam hauv 20UM saum toj ntawm cov khoom ua kom muaj kev phom sij rau kev noj qab haus huv. Lub tshuab nqus dej muaj tsawg dua 0.5NTU, CODMN tsawg dua 1.5mg / L, cov ntsiab lus hlau tsawg dua 0.05mg / L, SDI tsawg dua lossis sib luag rau 5. Cov lim dej yog ib hom "kev siv lub cev - tshuaj lom neeg", cov dej los ntawm cov ntaub ntawv ntau thaum cais cov lim dej tsis haum thiab colloidal kev ncua. Lub lim dej yog cov dej ntxuav dej tau txais txiaj ntsig thiab kev kho mob ntawm cov txheej txheem tseem ceeb hauv kev npaj cov dej ntshiab yog qhov txheej txheem tsis tseem ceeb.

Thib ob theem pretreatment (Lim lim) 

Cov pa roj carbon lim dej siv los tshem cov xim hauv dej, tsw ntxhiab tsw, muaj ntau ntawm cov tshuaj lom neeg thiab cov tsiaj txhu roj ntsha, txo cov khoom seem ntawm cov dej thiab tshuaj tua kab thiab lwm cov pa phem.

Tus qauv ntawm kev ua kom cov pa roj carbon lim dej thiab quartz xuab zeb lim, qhov sib txawv tau muab tso rau sab hauv lub zog adsorption muaj peev xwm ntawm kev ua kom cov pa roj carbon hlau rau kev tshem tawm los ntawm quartz xuab zeb lim tsis muaj lim tawm cov khoom siv organic, adsorption ntawm cov tshuaj ntxuav dej muaj dej ntau dua, siv dej ntau dua dua li los yog sib npaug nrog cov tshuaj chlorine 0.1ML / M3, SDI tsawg dua lossis sib luag rau 4, yog cov muaj zog oxidants chlorine, muaj ntau hom membrane puas, tshwj xeeb, thim rov qab osmosis daim nyias nyias yuav tsum paub ntau txog cov tshuaj chlorine. Tsis tas li ntawd, cov txheej txheem ua kom muaj zog, saum npoo ntawm cov pa roj carbon roj los ua cov txheej txheem uas tsis yog crystalline ntawm qee cov pa oxygen muaj cov pab pawg, cov pawg ua haujlwm no tuaj yeem muaj cov tshuaj adsorption ntawm cov roj carbon activated catalytic oxidation ntawm cov xov xwm phem, kom rov ua tau zoo, tuaj yeem muaj txiaj ntsig tshem tawm ib tug xov tooj ntawm cov hlau ions hauv dej.

Thib peb pretreatment (Resin mos)

Cationic resin siv rau cov dej muag, feem ntau yog tshem tawm cov dej tawv tawv. Lub zog ua kom tsis muaj dej yog qhov calcium uas loj (Ca2 +), magnesium (Mg2 +) ion sib xyaw, thaum muaj cov dej nyoos hardness ions dhau los ntawm txheej txheej, cov dej ntawm Ca2 +, Mg2 + tau sib pauv resin adsorption, thiab lwm yam khoom tib lub sij hawm qhov zoo ntawm kev tso tawm sodium Na + ions ntws los ntawm cov mos mos hauv dej yog tshem tawm ntawm cov dej muag muag tawv ions. Yog li kom tau txais txiaj ntsig zoo tiv thaiv kev thim rov qab osmosis membrane fouling.System tuaj yeem txiav recoil, thiab yog li liab.

Thib plaub theem pretreatment (Lim Micron) 

Qhov luaj li cas hauv dej kom tshem tau cov khoom zoo, cov xuab zeb lim tuaj yeem tshem tawm cov khoom me me ntawm colloidal hauv dej, kom cov dej noo tau mus txog 1 degree, tab sis tseem nyob rau ib nrab dej ntawm cov dej rau ntau pua txhiab ntawm qhov me me 1-5 microns colloidal hais, siab rau ntawm lub lim dej no kom tshem tawm cov dej tom qab ntawm qhov loj me ntawm 100 microns lossis tsawg dua ntawm cov kab me me, kom txo tau qhov ua kom nruj, kom ua tau raws li cov txheej txheem txuas ntxiv ntawm cov dej uas xav tau ntawm kev tiv thaiv ntawm cov txheej txheem tom ntej ntev.

Rov Qab Osmosis

Ntaus Rov Qab Osmosis yog ib qho khoom siv los ntxuav cov dej qab ntsev nrog kev ua ntawm lub siab sib txawv ntawm cov kab mob ib nrab permeable. Nws yog hu ua thim rov qab osmosis, vim nws yog qhov cuav rau kev nkag mus rau ntuj. Cov khoom sib txawv nyias muaj nyias osmotic pressures.

Cov thim rov qab osmosis tuaj yeem tshem tawm ntau dua li 97% ntawm cov dej ntsev thiab tshaj 99% cov colloid, kab mob me me, cov khoom tawm thiab cov khoom siv organic, ua qhov zoo tshaj plaws kev xaiv thawj cov khoom siv hauv kev tsim hluav taws xob ntawm cov dej ntshiab niaj hnub, dej ntshiab thiab qhov chaw dej. (lim dej ntshiab). Cov yam ntxwv tseem ceeb tshaj yog kev siv hluav taws xob tsawg, tsis muaj kuab paug, cov txheej txheem yooj yim, dej kom zoo thiab kev ua haujlwm yooj yim thiab txij nkawm.

RO nrog rov ntxuav lub taub-RO yog lub plawv kev kho dej, yog li peb npaj lub tshuab ntxhua khaub ncaws nrog huv sab hauv sab hauv RO kom ua kom cov RO npog ua haujlwm ntev dua.
