Indlela yokulinganisa inkqubo ye-RO yemizi-mveliso

Nantsi isikhokelo senyathelo ngenyathelo kwiiparameter eziphambili kunye nokubala okubandakanyekileyo ekulinganiseni ubungakanani benkqubo ye-RO yezimboni.

 

Inyathelo 1: Chaza iiMfuno eziPhambili ("Yintoni")

1. Izinga lokuhamba kwamanzi kwimveliso (Qp): Le yeyona mfuneko yakho iphambili. Zingaphi iigaloni ngomzuzu (GPM) okanye ii-cubic metres ngeyure (m³/h) yamanzi acocekileyo owadinga rhoqo? (umz., i-100 GPM yesityalo sokwenza imveliso).
2. Umgangatho Wamanzi Emveliso: Chaza ubuninzi obuvumelekileyo beTotal Dissolved Solids (TDS) okanye ubuninzi be-ion ethile (umz., i-silica, i-sodium, ii-chloride) emanzini agcweleyo. Oku kumisela ipesenti yokwaliwa kwetyuwa efunekayo.
3. Umthombo kunye noHlahlelo lwaManzi oNcedo: Le yeyona seti yedatha ibalulekileyo. Uhlalutyo lwamanzi olupheleleyo alunakuxoxiswana. Iiparameter eziphambili:

    ◦I-TDS, Ukuqhuba

    ◦Isalathisi soxinano lweSilt (SDI) okanye iTurbidity (ilinganisa amandla okungcola)

    ◦Uxinzelelo lwe: Calcium, Magnesium (ubulukhuni), Barium, Strontium (izikali ezidityanisiweyo), Silica, Iron, Manganese

    ◦i-pH, Ubushushu

    ◦I-Chlorine yasimahla (kufuneka ingabi nanto ukukhusela ii-membranes)

4. Iimeko Zokusebenza: Iiyure ngosuku, iintsuku ngeveki, ukufumaneka kwenkqubo okufunekayo.

 

Inyathelo lesi-2: Ubalo oluPhambili loYilo ("Ingakanani")

Ngeemfuno ezingasentla, wenza ezi zibalo:

1. Izinga lokuBuyiselwa kweNkqubo (%R): Ipesenti yamanzi okuphakelwa aguqulwe abe ngamanzi emveliso.

    ◦Ifomula: R (%) = (Ukuhamba kweMveliso / Ukuhamba kweZondlo) x 100

    ◦Isici Esithintelayo: Ukubuyiselwa kwe-recovery kuthintelwe ngamandla okwandisa amanzi okutya. Ukubuyiselwa kwe-recovery okuphezulu kuthetha ukuba umlambo oxineneyo (ongafunwayo) uba nzulu ngakumbi, nto leyo ebeka emngciphekweni ukuna kwe-scale kwi-membrane. Isoftware (efana ne-ROSA evela kwi-Dow/Chemours) isetyenziselwa ukumisela ukubuyiswa okuphezulu okuvumelekileyo ngokusekelwe kwikhemistri yakho yamanzi, i-antiscalant dosing, kunye nokulungiswa kwe-pH.

2. I-Concentration Factor (CF): Inxulumene nokuchacha.

    ◦Ifomula: CF = 1 / (1 - R) okanye CF = I-TDS Yondla / I-TDS Yokugxila

    ◦Umzekelo: Xa i-75% ye-recovery ibuya, i-concentrate ingaphezulu ngokuphindwe kane kune-feed (CF = 1/(1-0.75) = 4).

3. Imfuneko Yokuhamba Kokutya (Qf):

    ◦Ifomula: Qf = Qp / R

    ◦Umzekelo: Ukuba ufuna i-100 GPM yemveliso (Qp) kwi-75% yokubuyisela (R), udinga ukuhamba kwesondlo se: 100 / 0.75 = 133.3 GPM.

4. Ukugeleza kwe-Concentrate (Reject) (Qc):

    ◦Ifomula: Qc = Qf - Qp

    ◦Umzekelo: 133.3 - 100 = 33.3 GPM.

5. Uyilo lweMembrane Array:

    ◦Iinkqubo zoshishino zakhiwe "kwii-arrays" (umz., 2:1, 3:2:1 array) ukugcina isantya esaneleyo sokuhamba kwe-cross-flow kumphezulu we-membrane, nto leyo enciphisa ukungcola.

    ◦Inani leemithambo zoxinzelelo (iindlu) kunye nee-membranes limiselwa kukuhamba kokutya okufunekayo kunye neenkcukacha zomenzi zokujika.

6. I-Flux (GPD/ft)² okanye i-LMH): Izinga lokuhamba kwamanzi angena ngaphakathi kwe-membrane ngokweyunithi nganye.

    ◦Ifomula yendawo iyonke ye-membrane efunekayo: Indawo = Qp / Flux

    ◦Izikhokelo zeFlux: Zikhethwe ngokusekelwe kumgangatho wamanzi okutya (ukuhamba okuphantsi kwamanzi asemgangathweni ophantsi ukunciphisa ukungcola).

        ▪I-RO Igcwele (Ipasi yesi-2): 20-30 GFD

        ▪Amanzi oMthombo: 12-18 GFD

        ▪Amanzi angaphezulu: 8-14 GFD

        ▪Amanzi amdaka: 7-12 GFD

 

Inyathelo lesi-3: Ubungakanani bangaphambi koNyango kunye noBukhulu basemva koNyango ("Inkqubo yeNkxaso")

I-RO ayinakusebenza yodwa. Ubungakanani bayo bulawula ubungakanani bazo zonke izixhobo ezixhasayo.

1. Unyango lwangaphambi konyango (KUFUNEKA lwenziwe ngokusekelwe kuhlalutyo lwamanzi okutya):

    ◦Isihluzi seMultimedia: Sokususa izinto eziqinileyo ezixhonyiweyo. Ubungakanani boMsinga woKutya (Qf) kwisantya esiqhelekileyo sokuhamba kwenkonzo esiyi-5-10 GPM/ft².

    ◦Isithambisi okanye i-Antiscalant Injection: Ukulawula ukukala. Isithambisi silingana ne-Feed Flow (Qf) kunye nomthwalo wobunzima.

    ◦Isihluzi seKhabhoni okanye iSitofu seSodium Bisulfite: Sokususa i-chlorine. Ubungakanani be-Qf.

    ◦Isihluzi seKhatriji (5µ izihluzi zokhuseleko): Ubungakanani be-Qf.

2. Ukhetho lwePump yoXinzelelo oluPhezulu:

    ◦Kufuneka inikezele i-Qf kuxinzelelo olufunekayo ukuze yoyise uxinzelelo lwe-osmotic lwe-concentrated feed kunye nokulahlekelwa koxinzelelo lwenkqubo.

    ◦Uxinzelelo ludla ngokuba phakathi kwe-150-300 psi kumanzi amdaka, kunye ne-800-1200 psi kumanzi olwandle.

3. Emva koNyango:

    ◦Isicoci segesi okanye iMembrane: Ukususa i-CO2₂ ukuba i-pH ilungisiwe.

◦I-Mixed Bed Polisher (CEDI/EDI): Yamanzi acocekileyo kakhulu. Ubungakanani be-Qp.

 

Inyathelo lesi-4: Uyilo lweNkqubo kunye nokuCwangcisa

• Ipasi enye vs. Ipasi ephindwe kabini (ezimbini): Ipasi enye inokwanela. Ukuba kufuneka i-TDS ephantsi kakhulu (umz., kwiibhoyila ezinoxinzelelo oluphezulu, ii-semiconductors), i-permeate evela kwipasi yokuqala iba yi-feed ukuya kwinkqubo yesibini ye-RO.
• Ukubeka iSiteji yoQokelelo: Ukwandisa ukubuyiselwa kwayo yonke into, uqwalaselo oluvela kwibhanki yokuqala yee-membranes luba yi-feed ukuya kwibhanki yesibini. Le yingcamango "ye-2:1 array".

Isilumkiso esibalulekileyo kunye neengcebiso

• Musa Ukuyibamba. Unyango oluncinci okanye izinga lokubuyisela eligqithisileyo liya kukhokelela ekungcoleni okanye ekukhuleni kwe-membrane ngokukhawuleza, nto leyo ekhokelela ekungasebenzini ixesha elide kunye neendleko eziphezulu zokusebenza.
• Sebenzisa iSoftware yobuNgcali. Abavelisi beeMembrane (iDuPont, iHydranautics, iLG) banikezela ngesoftware yoyilo yasimahla (umz., iROSA, i-IMSDesign) ebonakalisa zonke iindlela zokunxibelelana phakathi kwekhemistri yamanzi, ukubuyisa, ukujikeleza, kunye nokulinganisa.
• Nxibelelana neNgcali. Kuzo naziphi na izicelo zoshishino (> 50 GPM), yindlela eqhelekileyo ukubandakanya injineli yeenkqubo zonyango lwamanzi okanye umdibanisi. Baza kwenza uvavanyo lovavanyo kumanzi olwenziwayo, oluyimigangatho yegolide yokunciphisa umngcipheko woyilo nokuqinisekisa ubungakanani obufanelekileyo. I-HID yi-RO membrane yobungcali kunye nomenzi weenkqubo ze-RO. Wamkelekile qhagamshelana ne-HID ukuze ufumane isisombululo okanye iingcebiso zobungcali.
