Vim li cas EDI Product Resistivity txo qis? Ua Tau Thiab Kev daws teeb meem

Hauv kev lag luam dej ntshiab thiab dej ultrapure tshuab, ibEDI dej kho qhov systemfeem ntau yog ntsia rau hauv qab ntawm RO kom tshem tawm ions ntawm dej ntxiv. Thaum lub sijhawm ua haujlwm ib txwm, EDI cov khoom siv dej tiv thaiv yuav tsum nyob ruaj khov. Yog tias EDI cov khoom tiv thaiv maj mam txo qis tom qab lub kaw lus tau ua haujlwm rau qee lub sijhawm, ntau tus neeg siv yuav xav thawj zaug seb EDI module puas ua tsis tau.Txawm li cas los xij, tsis tshua muaj kev tiv thaiv tsis tas txhais tau tias EDI module puas lawm.Kev txo qis hauv EDI cov khoom siv dej tiv thaiv yuav tshwm sim los ntawm kev hloov pauv hauv RO permeate zoo, lossis nws yuav cuam tshuam nrog EDI pub txaus, tam sim no, voltage, siab, fouling, lossis scaling. Yog li ntawd, kev daws teeb meem zoo yuav tsum tsis txhob pib nrog "huv EDI tam sim ntawd." Hloov chaw, qhov ua rau muaj peev xwm yuav tsum tau txo qis ib kauj ruam raws li cov ntaub ntawv khiav haujlwm.

Ib qho kev daws teeb meem yooj yim dua rau cov ntawv thov kev lag luam yog:

Kev ntsuas → Pub dej → Flow → Tam sim no & Voltage → Siab → Fouling / Scaling → Module Condition

Hauv lwm lo lus, ua ntej txheeb xyuas tias qhov ntsuas tau ntseeg tau, tom qab ntawd txiav txim siab seb EDI pub dej hloov pauv, thiab tsuas yog tom qab ntawd tshawb xyuas EDI module nws tus kheej.

EDI Product Resistivity Qhia koj li cas?

EDI siv ion txauv resins, ion- cov txheej txheem xaiv, thiab ncaj qha - tam sim no hluav taws xob tam sim no kom tshem tawm cov ions ntawm dej tsis tu ncua. Qhov tsawg dua ions nyob hauv cov khoom dej, qhov siab dua qhov feem ntau yog. Hloov pauv, thaum cov ntsiab lus ionic nce, EDI cov khoom tiv thaiv txo qis.

Yog li ntawd, thaum hloov pauv hloov, cov lus nug tseem ceeb tsis yog yooj yim, "Puas yog EDI puas?" tab sis theej:"Puas yog cov ionic load nkag mus rau EDI nce, lossis EDI tus kheej deionization muaj peev xwm txo?"Ob qhov xwm txheej no xav tau kev kho kom raug sib txawv kiag li.

Cov txheej txheem kev lag luam raug tuaj yeem sawv cev raws li:Pretreatment → RO → EDI → Siab -Purity Dej

Yog li ntawd, EDI kev ua tau zoo muaj feem cuam tshuam nrog rau cov dej ntws RO. Ib qho ruaj khovEDI dej kho qhov systemua ntej yuav tsum tau ruaj khov RO permeate raws li nws cov dej pub.

Kauj Ruam 1: Tshawb xyuas qhov ntsuas qhov ntsuas ua ntej

Ua ntej ua qhov kev daws teeb meem EDI nyuaj, ua ntej txheeb xyuas seb qhov ntsuas ntsuas nws tus kheej puas ntseeg tau.Yog hais tias lub conductivity / resistivity sensor yog fouled, tsis raug calibrated, cuam tshuam los ntawm qhov txawv txav kub them, los yog muaj ib tug teeb meem nyob rau hauv, lub system yuav qhia tau hais tias ib tug txo nyob rau hauv resistivity txawm hais tias cov khoom tiag tiag dej zoo tsis tau hloov mus rau tib yam.

Yog li ntawd, yog tias EDI cov khoom tiv thaiv hloov pauv sai sai, sib piv cov kev nyeem tam sim no nrog rau lwm cov dej tsis zoo, xws li:

Pub Conductivity + Product Conductivity / Resistivity + Kub

Yog tias tsuas yog ib qho kev nyeem ntawv hloov pauv tam sim ntawd thaum lwm qhov kev khiav hauj lwm tsis ruaj khov, qhov ntsuas yuav tsum tau kuaj xyuas ua ntej es tsis txhob kho EDI kev khiav hauj lwm tam sim ntawd.Qhov teeb meem no yooj yim rau kev saib xyuas tab sis tseem ceeb heev hauv kev daws teeb meem cov cuab yeej siv.

Kauj ruam 2: Xyuas RO Permeate Conductivity rau EDI

Yog tias qhov ntsuas ntsuas tau ua haujlwm zoo, cov kauj ruam tom ntej yog kuaj xyuas RO permeate.EDI tsis yog ib qho kev ywj pheej "kev kho mob zaum kawg." Yog hais tias RO desalination kev ua tau zoo zuj zus lawm, lub ionic load nkag mus rau EDI nce, uas yuav nws thiaj li ua rau qis EDI cov khoom dej resistivity.

Piv txwv li:

RO Permeate Conductivity ↑
