Cov xwm txheej ntawm daim ntawv thov thiab pub- Dej Ciam Dej Ntawm Ob -Pass RO + EDI

1. EDI Pub Tolerance Window: Ib Lub Rooj Koj Yuav Tsum Nyeem

1.1 Vim li cas EDI thiaj li Picky Txog Pub

Xav txog EDI li "khoom noj qab zib": nws tuaj yeem ua cov tais diav uas huv heev los ntawm cov dej huv, tab sis pov rau hauv cov pob txha tawv (hardness), xuab zeb (silica), kua qaub (CO₂), tshuaj lom (chlorine), lossis roj (organics), thiab nws tsis tsuas yog ua tsis tau lub tais tab sis ua rau lub lauj kaub. Lub qhov rais EDI pub kam rau ua raws nraim li "cov qauv kev lees paub." Tshaj ntawm lub qhov rais, me ntsis qhov kev tiv thaiv te thiab tu ntau ntau, cov pawg loj thiab cov resin yog irreversibly puas. Tag nrho vim li cas aMuab ob npaug rau RO System Rau EDI Pretreatmentmuaj yog los xyuas kom meej cov dej xa mus rau lub qhov rais yog ib txwm tsim nyog. Kev nkag siab cov lus no tseem ceeb tshaj qhov nco txog txhua tus qauv.

1.2 Txhaum Qhov Kev Ua Siab ntev rau hauv "Zoo heev-Zoo-Fair-Poor"

Rau engineering, tsaws lub qhov rais kam rau ua plaub pawg - Zoo heev / Zoo / Ncaj Ncees / Tsis zoo - yog qhov ua tau zoo dua li kev sib tw ib qho kev txwv: Zoo heev yog EDI qhov kev nplij siab, Zoo yog qhov tau txais tab sis saib, Ncaj ncees yog kab lus ceeb toom, Cov neeg pluag yog untouchable. Qhov no muab kev ua haujlwm elasticity, tsim cov npoo, thiab kev txiav txim sai ntawm leej twg hla txoj kab thaum yam tsis raug. Txoj kev plaub -band kuj yooj yim hla- kev sib txuas lus hauv chaw ua haujlwm - txheej txheem, O&M, thiab kev yuav khoom tau nyeem tib yam liab- teeb ntsuab, tsis yog tib lub xov tooj.

Daim duab: EDI pub kam rau ua qhov rai: ob npaug - dhau RO thawb pub rau hauv Cov Pab Pawg Zoo / Zoo

2. Plaub qhov kev thov ib yam nkaus

2.1 Fais fab Boiler Ua-Ua dej

Siab -siab boilers thiab turbines yog qhov rhiab heev rau ua - dej: txawm silica thiab hardness nplai ntawm boiler raj thiab siab - parameter blades, ua rau efficiency poob los yog txawm lub raj tawg thiab kaw. Qhov xwm txheej no qhov kev thov rau kev hla thib ob yog "rigid" - nws xav tsis zoo - saib kev tiv thaiv tab sis silica thiab hardness nias rau qhov tsawg kawg nkaus. Ob Chav Pass RO System Rau EDI Pretreatment yuav luag yog tib qho kev xaiv ntawm no, vim tias tus nqi ntawm kev sib tsoo boiler dwarfs tus nqi thib ob - dhau RO.

2.2 Pharma PW / WFI

Pharmaceutical Purified Water (PW) thiab Dej rau Txhaj Tshuaj (WFI) zaum nyob rau hauv cov chaw muag tshuaj nruj me ntsis thiab hais txog "kev ruaj ntseg tsis tu ncua, txheeb xyuas tau, traceable." EDI, ua kua qaub/caustic-dawb uas tsis muaj tshuaj lom neeg pov tseg, yog lub hauv paus polishing theem nyob rau hauv niaj hnub pharma dej systems; nws cov khoom noj yuav tsum huv txaus kom paub tseeb. Qhov thib ob - dhau RO ntawm no ua haujlwm rau ob qho tib si cov txheej txheem xav tau thiab kev ua raws li xav tau - tus kws tshuaj xyuas yuav tsis lees txais EDI pub uas qee zaus tawm ntawm spec tsuas yog vim qhov kev tiv thaiv zoo.

2.3 Microelectronics Ultrapure Dej

Wafer tu tolerates tsis tshua muaj kab ions thiab hais, thawb resistivity nyob ze ntawm theoretical txwv. Ntawm no, ua ntej -pass permeate qhov seem conductivity thiab CO₂ ncaj qha hem qhov kawg spec, ua qhov thib ob dhau yuav luag tus qauv. Ib qho kev xav ntawm kev tso tseg qhov thib ob hla tam sim ntawd rov qab los ntawm qhov kawg resistivity. Rau cov kab uas nws cov txiaj ntsig tau raug nqi rau qhov chaw lej, qhov thib ob yog kev yuav ntawv pov hwm, tsis yog kev xav.

2.4 Haus dej thiab txheej txheem dej

Cov dej haus thiab cov txheej txheem dav dav muaj cov kev xav tau purity ntau dua li qhov saum toj no peb, tab sis qhov twg saj ruaj khov, kev sib xyaw ua ke, lossis qhov tshwj xeeb siab - purity txheej txheem dej koom nrog, ib qho thib ob - dhau RO + EDI tseem xa tawm "cov zis tsis cuam tshuam los ntawm raw- dej hloov pauv." Qhov xwm txheej no qhov kev thov rau ob qhov dhau los yog "hloov" - nyob ntawm qhov dej zoo thiab qhov khoom muag. Tsis yog txhua cov nroj tsuag no xav tau ob zaug dhau los, tab sis cov uas siv ib qho feem ntau txuag tau ntau cov lus piav qhia thaum lub sijhawm cov neeg siv khoom nruj tshaj plaws.

Daim duab: Plaub qhov xwm txheej: boiler / pharma / microelectronics / dej haus - txheej txheem dej

3. Cov xwm txheej txawv li cas hauv "Hard Demand" rau ob zaug dhau

3.1 Qhov twg pH-Ntev Thib Ob Pass yog qhov tseem ceeb

Boilers thiab microelectronics yuav luag yeej xav tau ib qho pH interstage - nqa thib ob dhau - vim silica thiab boron yog lawv cov ntshav, thiab tsuas yog ionization tsis lees paub lawv huv si. Rau cov xwm txheej no qhov kev hla thib ob tsis yog "zoo dua" tab sis "yuav tsum tau ua." Kev kho "yuav tsum tau" raws li "yeem" los txiav cov peev nyiaj yog qhov feem ntau thiab kim tshaj plaws tsim yuam kev hauv tej yaam num.

3.2 Qhov twg muaj kev sib haum xeeb

Cov dej haus thiab cov txheej txheem dav dav, yog ib txwm mos, qis -CO₂, qis-silica, tuaj yeem pub EDI zoo txaus los ntawm ib zaug - dhau RO ntxiv rau degassing lossis softening. Tab sis lo lus "yuav" yuav tsum tau lees paub los ntawm daim ntawv qhia dej, tsis tau twv. Lub hauv paus ntawm kev sib haum xeeb yeej ib txwm tau ua dej num ua ntej - kev sib haum xeeb yam tsis muaj ntawv ceeb toom tsuas yog kev twv txiaj ntawm koob hmoov.

4. Kev hloov kho rau Offshore thiab Thawv Lub Luag Haujlwm

4.1 Compact, Unmanned Requirements

Ultrapure-dej xav tau ntawm cov Islands tuaj, offshore platforms, thiab tej thaj chaw deb feem ntau tsis tuaj yeem pab txhawb O&M tag nrho. Lawv xav "nruab, tswj me me, tsis txhob nres." AMuab ob npaug rau RO System Rau EDI Pretreatmentib txwm haum rau cov thawv ntim khoom: ntim ob qho tib si RO hla, ntu ntu, EDI, thiab tswj rau hauv ib lub thawv txheem, khiav los ntawm kev sib txuas fais fab thiab dej ntawm qhov chaw, nrog rau tej thaj chaw deb conductivity thiab tswb xyuas. Rau lub luag haujlwm tsis muaj neeg siv, lub kaw lus "tus kheej- tiv thaiv" (interlocks, tswb, pib-kev hloov pauv) tseem ceeb tshaj qhov ua tau zoo tshaj plaws.

4.2 Yuav ua li cas Modularization Lands

Qhov nyuaj ntawm modularization tsis yog "cov khoom siv ntim rau hauv lub thawv" tab sis "ua kom lub interstage txhim khu kev qha nyob rau hauv bumpy, siab- ntsev- pos huab, dav - qhov kub thiab txias." Tsawg flanges, ntsev- huab- cov cuab yeej tiv taus, thiab lub network- yuav tsum tau tswj xyuas kom zoo. Cov ntsiab lus no txiav txim siab seb lub thawv ntim khoom kav ntev li tsib xyoos lossis tsib lub hlis ntawm ib kob. Offshore kev ua tsis tiav yog kaum rau ib qho, qhov tsis ua tiav tsis yog lub hauv paus ntsiab lus tsis yog tab sis tsis tsim nyog ib puag ncig hloov pauv.

4.3 O&M Interfaces ntawm Lub Thawv System

Thaum lub thawv tuaj txog ntawm qhov chaw, qhov nyuaj tiag tiag yog qhov "interface," tsis yog cov khoom siv: dej, fais fab, thiab qhov dej sib txuas xav tau cov npoo; kev saib xyuas tej thaj chaw deb yuav tsum muaj sia nyob network poob; tswb yuav tsum thawb mus rau cov xov tooj, tsis tsuas yog lub teeb ntawm lub thawv sab nrauv. Ntau qhov teeb meem ntawm ntug dej hiav txwv tsis tawg hauv - cov khoom siv hauv lub thawv tab sis tsis zoo sib txuas tawm - ntawm - lub thawv cuam tshuam - xws li ntws rov qab - siab choking lub concentrate rov qab los, los yog tsis ncaj ncees lawm ob - dhau lub twj tso kua mis ib ntus tom qab lub hwj chim- rov qab pib dua. Sau cov kev cuam tshuam no ua ib daim ntawv txheeb xyuas thiab kos txhua qhov ntawm qhov chaw yog qhov tseeb tshaj li qhov "kev tu-dawb" thov.

5. Peb -Cov Lus Nug Txog Kev Txiav Txim Dua Ob Qhov Pass

Tig ib qho EDI pem hauv ntej-kawg configuration, nug peb yam: ua ntej, dab tsi yog kuv raw - dej CO₂, silica, hardness, thiab boron? Qhov thib ob, kuv cov dej ntws tawm tiag tiag xav tau li cas (boiler? pharma? microelectronics? lossis txheej txheem zoo tib yam)? Qhov thib peb, kuv lub peev xwm O&M puas tuaj yeem tiv taus "ib zaug- dhau kev pub noj qee zaus tawm ntawm spec"? Ib zaug teb, seb ob daim ntawv lees paub teb nws tus kheej. Daim ntawv txheeb xyuas tus nqi yog tig "peb puas xav tau kev hla ob zaug" los ntawm mysticism rau hauv kev txiav txim siab engineering tsis raug.

Los ntawm txoj kev, ntawm peb lo lus nug thawj (cov ntaub ntawv nyoos- dej) feem ntau yog hla. Ntau qhov dej num kho qhov teeb tsa yam tsis muaj cov khoom nyoos zoo - kev tshuaj xyuas dej, xaus rau - lossis qis dua - tsim. Ua cov lus nug thawj zaug ua rau ob leeg teb lawv tus kheej - cov ntaub ntawv yeej ib txwm yog qhov kev txiav txim siab pheej yig tshaj plaws, thiab kab sib cais "engineering" los ntawm "kev twv."

6. Muaj ob hom kev paub tsis meej

6.1 Sib npaug "Resistivity in Spec" nrog "System Healthy"

Ntau qhov chaw tsuas yog saib qhov kev tiv thaiv zaum kawg thiab ua kev zoo siab thaum nyob hauv spec.Tab sis qhov resistivity yog qhov ntsuas tau, tsis yog qhov ntsuas kev noj qab haus huv. Nws tuaj yeem saib zoo yooj yim vim tias EDI pawg tseem tab tom tiv nrog tawm - ntawm - cov khoom noj tshwj xeeb, ntawm tus nqi ntawm cov khoom siv lub neej. Qhov taw qhia txog kev noj qab haus huv tiag tiag yog qhov thib ob -dhau permeate conductivity - "feed gate" - uas yog qhov tseeb qhia txog kev noj qab haus huv.

6.2 Copying Lwm tus neeg txoj kev teeb tsa

"Plant A siv ob zaug dhau, yog li kuv yuav" yog lwm qhov kev tsis ncaj ncees. Lawv cov dej nyoos, dej ntws, thiab O&M txawv ntawm koj li, yog li kev teeb tsa yuav tsum sib txawv. Qhov kev pheej hmoo loj tshaj plaws ntawm kev luam yog tej zaum ob qho tib si siv ob npaug - nyiaj dhau thiab tsis daws koj tus kheej cov kab mob tseem ceeb. Kev teeb tsa yuav tsum loj hlob ntawm koj tus kheej daim ntawv qhia dej.

7. Kev tsaws lub qhov rais Tolerance raws li kev khiav hauj lwm SOP

Tsiv cov "Zoo / Zoo / Ncaj Ncees / Tsis Txaus" los ntawm kev tsim duab kos rau hauv kev ua haujlwm txhua hnub yog thaum lub qhov rais kam rau ua tiag them. Concretely: teem peb kab rau txhua thib ob -pass permeate qhia - ntsuab khiav kab (Zoo heev), daj ceeb toom kab (Zoo/Fair ciam), liab diversion kab (Poor); Cov neeg ua haujlwm saib xim txhua hnub, O&M coj saib kev sib tw txhua lub lim tiam, tswj saib TCO txuas txhua hli. Thaum qhov taw qhia tsis tu ncua ze rau daj, ua rau muaj teeb meem (puas yog pretreatment poob lub pob, los yog interstage dosing tsis ruaj khov?) es tsis tos kom nws hla liab thiab poob EDI resistivity. Tig lub qhov rais mus rau hauv SOP sib npaug ntawm kev txhim kho "yeej tsis- tus neeg saib xyuas lub rooj vag" rau tag nrho cov kab, muaj kev ntseeg siab dua li tib neeg saib.

8. Kaw: Dej Ntsuas Ua Ntej → Dej Qib Tom ntej → Them Rov Qab Kawg

Methodology tseem tuav:ua qhov dej tshuav ua ntej- volume, fluctuation, concentrated destination;ces muab qib dej zoo- tau qhab nia dej nyoos tawm tsam EDI qhov kev kam rau siab qhov rais los ntawm pawg los txiav txim siab seb qhov thib ob dhau los thiab kev cuam tshuam yuav tsum tawm tsam CO₂, silica, lossis boron;Thaum kawg suav lub sijhawm them rov qab- ntsuas qhov thib ob qhov kev nqis peev tiv thaiv kev nyab xeeb ntawm boiler, kev ua raws li pharmacopeia, thiab wafer tawm los nws tiv thaiv. Taihe Environmental Protection, nyob rau hauv scenario-raws li kev sib koom ua ke ntawm ob- dhau RO nrog EDI pretreatment, ua raws nraim li qhov "dej sib npaug - dej grading - payback" logic los tsim UPW kab uas yog ob qho tib si nyob rau hauv - spec thiab check, tuned rau lub luag hauj lwm ntawm micro boilers, pharronics.
