Yuav ua li cas kom loj hlob lub tshuab RO industrial

Nov yog cov lus qhia ib kauj ruam zuj zus rau cov kev ntsuas tseem ceeb thiab kev xam suav nrog hauv kev ntsuas qhov system RO kev lag luam.

 

Kauj Ruam 1: Txhais Cov Kev Xav Tau Tseem Ceeb ("Dab Tsi")

1. Tus Nqi Dej Ntws Khoom (Qp): Qhov no yog koj qhov yuav tsum tau ua tseem ceeb. Muaj pes tsawg gallons ib feeb (GPM) lossis cubic meters ib teev (m³/h) ntawm cov dej huv koj puas xav tau tas li? (piv txwv li, 100 GPM rau lub Hoobkas tsim khoom).
2. Qhov Zoo ntawm Cov Dej Khoom: Txhais qhov siab tshaj plaws uas tso cai rau Tag Nrho Cov Khoom Uas Yaj Tau (TDS) lossis cov ion concentration tshwj xeeb (piv txwv li, silica, sodium, chlorides) hauv cov dej permeate. Qhov no txiav txim siab qhov feem pua ​​​​​​ntawm kev tsis lees paub ntsev uas xav tau.
3. Qhov Chaw Muab Dej Pub Noj & Kev Tshawb Fawb: Qhov no yog cov ntaub ntawv tseem ceeb tshaj plaws. Kev tshawb fawb txog dej kom ntxaws tsis tuaj yeem sib tham tau. Cov yam ntxwv tseem ceeb:

    ◦TDS, Kev Ua Hluav Taws Xob

    ◦Cov Ntsuas Qhov Ceev ntawm Cov Av Av (SDI) lossis Qhov Turbidity (ntsuas qhov muaj peev xwm ua rau av qias)

    ◦Cov Kev Ntsuas ntawm: Calcium, Magnesium (qhov nyuaj), Barium, Strontium (cov nplai formers), Silica, Hlau, Manganese

    ◦pH, Kub

    ◦Cov tshuaj Chlorine dawb (yuav tsum yog xoom los tiv thaiv cov ntaub so ntswg)

4. Cov Xwm Txheej Ua Haujlwm: Teev ib hnub, hnub ib lim tiam, qhov system xav tau.

 

Kauj Ruam 2: Kev Xam Tus Qauv Tseem Ceeb (Tus "Nyiaj Ntau Npaum Li Cas")

Nrog rau cov kev cai saum toj no, koj ua cov kev suav no:

1. Tus Nqi Rov Qab Zoo ntawm Lub Cev (%R): Feem pua ​​ntawm cov dej pub hloov mus ua dej khoom.

    ◦Cov mis: R (%) = (Cov khoom ntws / Cov khoom noj ntws) x 100

    ◦Qhov Txwv: Kev rov qab los ntawm cov dej pub dej muaj peev xwm nce mus txog qhov loj me. Kev rov qab los ntau dua txhais tau tias cov dej concentrate (reject) yuav nce mus txog qhov loj me, ua rau muaj kev pheej hmoo ntawm cov nplai ntawm daim nyias nyias. Cov software (xws li ROSA los ntawm Dow/Chemours) siv los ua qauv rau qhov rov qab los ntau tshaj plaws raws li koj cov tshuaj lom neeg hauv dej, kev siv tshuaj antiscalant, thiab kev kho pH.

2. Qhov Ntsuas Ntsuas (CF): Muaj feem cuam tshuam nrog kev rov zoo.

    ◦Cov mis: CF = 1 / (1 - R) los yog CF = Pub TDS / Concentrate TDS

    ◦Piv txwv li: Thaum rov qab tau 75%, cov khoom noj uas muaj concentrated yuav muaj concentrated ntau dua li cov khoom noj uas pub rau tsiaj noj 4 npaug (CF = 1/(1-0.75) = 4).

3. Kev Xav Tau Kev Pub Noj (Qf):

    ◦Cov mis: Qf = Qp / R

    ◦Piv txwv li: Yog tias koj xav tau 100 GPM ntawm cov khoom (Qp) ntawm 75% rov qab los (R), koj xav tau cov dej ntws ntawm: 100 / 0.75 = 133.3 GPM.

4. Kev Ntsuas (Tsis lees txais) Cov Ntws (Qc):

    ◦Cov mis: Qc = Qf - Qp

    ◦Piv txwv li: 133.3 - 100 = 33.3 GPM.

5. Kev Tsim Qauv Membrane:

    ◦Cov txheej txheem kev lag luam raug tsim ua "arrays" (piv txwv li, 2:1, 3:2:1 array) kom tswj tau qhov ceev ntawm cov dej ntws hla qhov chaw ntawm daim nyias nyias, uas txo qhov kev ua qias tuaj.

    ◦Tus naj npawb ntawm cov hlab ntsha siab (chaw nyob) thiab cov daim nyias nyias yog txiav txim siab los ntawm qhov dej ntws uas xav tau thiab cov lus qhia ntawm cov chaw tsim khoom rau cov dej ntws.

6. Flux (GPD/ft)² los yog LMH): Tus nqi ntws ntawm permeate ib cheeb tsam ntawm daim nyias nyias.

    ◦Cov mis rau tag nrho thaj tsam membrane xav tau: Cheeb Tsam = Qp / Flux

    ◦Cov Lus Qhia Txog Kev Hloov Pauv: Xaiv raws li qhov zoo ntawm cov dej pub (kev hloov pauv tsawg dua rau cov dej tsis zoo kom txo tau qhov qias neeg).

        ▪RO Permeate (2nd Pass): 20-30 GFD

        ▪Dej Qhov Dej: 12-18 GFD

        ▪Dej Nto: 8-14 GFD

        ▪Dej khib nyiab: 7-12 GFD

 

Kauj Ruam 3: Kev Kho Mob Ua Ntej & Kev Ntsuas Tom Qab Kev Kho Mob (Lub "Txhawb Nqa")

Lub RO tsis tuaj yeem ua haujlwm ib leeg. Nws qhov loj me qhia txog qhov loj ntawm txhua yam khoom siv txhawb nqa.

1. Kev kho ua ntej (YUAV TSUM tsim raws li kev tshuaj xyuas dej pub):

    ◦Lim Multimedia: Rau kev tshem tawm cov khoom uas raug tshem tawm. Loj rau qhov Feed Flow (Qf) ntawm tus nqi ntws ib txwm ntawm 5-10 GPM/ft².

    ◦Tshuaj Softener los yog Antiscalant Txhaj Tshuaj: Txhawm rau tswj kev scaling. Tshuaj Softener raug ntsuas rau qhov Feed Flow (Qf) thiab qhov hardness loading.

    ◦Lim Carbon los yog Sodium Bisulfite Txhaj Tshuaj: Rau kev tshem tawm chlorine. Loj rau Qf.

    ◦Lub lim dej (5µ cov lim dej kev nyab xeeb): Loj rau Qf.

2. Kev Xaiv Twj Tso Kua Siab Siab:

    ◦Yuav tsum xa Qf ntawm qhov siab xav tau kom kov yeej qhov siab osmotic ntawm cov khoom noj uas muaj concentrated thiab qhov poob siab ntawm lub kaw lus.

    ◦Feem ntau qhov siab yog li ntawm 150-300 psi rau cov dej brackish, 800-1200 psi rau dej hiav txwv.

3. Tom Qab Kev Kho Mob:

    ◦Degasifier lossis Membrane Contactor: Txhawm rau tshem tawm CO₂ yog tias pH tau hloov kho.

◦Tshuab Txhuam Txhuam (CEDI/EDI): Rau cov dej huv heev. Loj rau Qp.

 

Kauj Ruam 4: Kev Tsim Qauv thiab Kev Npaj Ua Haujlwm

• Kev Dhau Ib Zaug vs. Kev Dhau Ob Zaug (Ob Zaug): Kev dhau ib zaug xwb tej zaum yuav txaus. Yog tias xav tau TDS qis heev (piv txwv li, rau cov boilers siab, semiconductors), qhov permeate los ntawm thawj zaug dhau los ua qhov pub rau lub kaw lus RO thib ob.
• Kev Npaj Cov Tshuaj Kom Qhuav: Yuav kom ua kom rov zoo tag nrho, cov tshuaj kom qhuav los ntawm thawj lub txhab ntawm daim nyias nyias yuav dhau los ua cov khoom noj rau lub txhab thib ob. Qhov no yog lub tswv yim "2:1 array".

Cov Lus Ceeb Toom Tseem Ceeb & Cov Lus Qhia

• Tsis Txhob Ua Li No. Kev kho ua ntej tsis loj lossis kev rov zoo sai dhau yuav ua rau daim nyias nyias puas sai lossis tawg, ua rau lub sijhawm tsis ua haujlwm ntev thiab cov nqi ua haujlwm siab.
• Siv Cov Software Tshaj Lij. Cov chaw tsim khoom membrane (DuPont, Hydranautics, LG) muab cov software tsim qauv dawb (piv txwv li, ROSA, IMSDesign) uas ua qauv rau txhua qhov kev sib cuam tshuam ntawm cov tshuaj lom neeg dej, kev rov qab los, cov dej ntws, thiab kev ntsuas.
• Sab laj nrog ib tug kws tshaj lij. Rau txhua qhov kev siv hauv kev lag luam tiag tiag (> 50 GPM), nws yog ib qho kev coj ua ib txwm muaj los koom nrog tus kws kho dej lossis tus neeg koom ua ke. Lawv yuav ua qhov kev sim ua ntej ntawm cov dej pub tiag tiag, uas yog tus qauv kub rau kev txo qhov kev pheej hmoo ntawm kev tsim thiab xyuas kom meej qhov loj me zoo tshaj plaws. HID yog tus kws tshaj lij RO membrane thiab RO system chaw tsim khoom. Txais tos sab laj nrog HID rau kev daws teeb meem lossis cov lus qhia tshaj lij.
