Ultrafiltration thiab thim rov qab osmosis yog cov txheej txheem dej lim dej muaj zog tshaj plaws. Ob leeg muaj cov khoom pom zoo, tab sis lawv txawv ntawm qee txoj hauv kev tseem ceeb. Txhawm rau txiav txim siab seb qhov twg yog qhov zoo rau koj lub tsev, cia peb nkag siab zoo dua ob lub tshuab no.

Puas yog ultrafiltration tib yam li thim rov qab osmosis?

Tsis yog. Ultrafiltration (UF) thiab thim rov qab osmosis (RO) yog cov txheej txheem kho dej muaj zog thiab ua haujlwm tau zoo tab sis UF txawv ntawm RO hauv ob peb txoj hauv kev tseem ceeb:

• Lim tawm cov khib nyiab / cov khoom me me li 0.02 micron nrog rau cov kab mob. Tsis tshem tawm cov ntxhia hauv dej, TDS, thiab cov tshuaj yaj hauv dej.
• Tsim cov dej raws li qhov xav tau - tsis xav tau lub tank cia
• Tsis tsim dej tsis lees (kev txuag dej)
• Ua haujlwm zoo nyob rau hauv qis qis - tsis muaj hluav taws xob xav tau

Qhov txawv ntawm UF thiab RO yog dab tsi?

Hom kev siv tshuab membrane

Ultrafiltration tsuas yog tshem tawm cov khoom seem thiab cov khib nyiab, tab sis nws ua li ntawd ntawm qib microscopic; Lub membrane pore loj yog 0.02 micron. Saj-wise, ultrafiltration khaws cov zaub mov uas cuam tshuam li cas dej saj.

Rov qab osmosis tshem tawm txhua yam hauv dejsuav nrog feem ntau ntawm cov ntxhia hauv yaj thiab yaj yaj. Ib qho RO membrane yog ib qho permeable membrane uas muaj qhov pore loj ntawm kwv yees li0.0001 micron. Yog li ntawd, RO dej yog zoo nkauj npaum li "tseem" vim nws tsis muaj cov zaub mov, tshuaj, thiab lwm yam organic thiab inorganic compounds.

Qee cov neeg nyiam lawv cov dej kom muaj cov zaub mov hauv nws (uas UF muab), thiab qee cov neeg nyiam lawv cov dej kom huv thiab tsis qab (uas RO muab).

Ultrafiltration muaj lub hollow fiber ntau daim nyias nyias yog li nws yog ib qho kev lim dej ntawm cov qib super zoo uas txwv tsis pub cov khoom thiab cov khib nyiab.

Rov qab osmosis yog txheej txheem uas cais cov molecules. Nws siv lub semi-permeable membrane cais inorganics thiab yaj inorganics los ntawm cov dej molecule.

Lub tank cia

UF tsim cov dej raws li qhov xav tau uas mus ncaj nraim rau koj lub faucet - tsis muaj lub tank cia.

RO xav tau lub tank cia vim nws ua rau dej qeeb heev. Lub tank cia yuav siv qhov chaw hauv qab lub dab dej. Tsis tas li ntawd, RO tso tsheb hlau luam tuaj yeem loj hlob cov kab mob yog tias tsis ua kom huv huv tsis tu ncua.Koj yuav tsum ntxuav koj lub cev tag nrho nrog rau lub tanktsawg kawg ib xyoos ib zaug.

Dej khib nyiab / Tsis lees paub

Ultrafiltration tsis tsim cov dej khib nyiab (tsis lees paub) thaum lub sij hawm filtration.*

Nyob rau hauv lub rov qab osmosis, muaj cross-flow pom los ntawm daim nyias nyias. Qhov no txhais tau hais tias ib tug kwj dej (permeate / khoom dej) mus rau lub tank cia, thiab ib tug kwj nrog tag nrho cov kab mob thiab yaj inorganics (tsis lees paub) mus rau ntws. Feem ntau rau txhua 1 nkas loos ntawm RO dej tsim,3 nkas loos raug xa mus rau ntws.

Kev teeb tsa

Kev txhim kho RO system yuav tsum tau ua ob peb qhov sib txuas: cov khoom noj khoom haus, cov kab ntws tawm rau cov dej tsis lees paub, lub tank cia, thiab cov pa tawm cua.

Kev txhim kho cov txheej txheem ultrafiltration nrog lub flushable membrane (qhov tseeb hauv UF thev naus laus zis *) yuav tsum tau ua ob peb qhov kev sib txuas: cov khoom noj khoom haus, cov kab ntws los yaug cov membrane, thiab rau cov faucet tshwj xeeb (kev siv dej haus) lossis cov khoom siv hluav taws xob (tag nrho. daim ntawv thov hauv tsev lossis kev lag luam).

Txhawm rau txhim kho cov txheej txheem ultrafiltration yam tsis muaj lub tshuab nqus dej, tsuas yog txuas lub kaw lus rau cov khoom noj khoom haus thiab rau lub faucet tshwj xeeb (dej rau cov ntawv thov haus) lossis cov khoom siv hluav taws xob (tag nrho lub tsev lossis cov ntawv thov kev lag luam).

UF puas tuaj yeem txo TDS?

Ultrafiltration tsis tshem tawm cov khoom tawg lossis TDS yaj hauv dej;nws tsuas yog txo thiab tshem tawm cov khib nyiab / particulates. UF tuaj yeem txo qee cov kua nplaum tag nrho (TDS) qhov xwm txheej vim nws yog ultrafine filtration, tab sis raws li txheej txheem ultrafiltration tsis tshem tawm cov ntxhia yaj, yaj ntsev, yaj hlau, thiab cov khoom yaj hauv dej.

Yog tias koj cov dej nkag los muaj qib TDS siab (dhau 500 ppm) ultrafiltration tsis pom zoo; Tsuas yog rov qab osmosis yuav ua tau zoo kom tau TDS nqis.

Qhov twg zoo dua RO lossis UF?

Rov qab osmosis thiab ultrafiltration yog qhov zoo tshaj plaws thiab muaj zog tshuab muaj. Qhov kawg uas zoo dua yog qhov kev nyiam ntawm tus kheej raws li koj cov dej num, nyiam saj, qhov chaw, lub siab xav khaws dej, dej siab, thiab lwm yam.

Cov Dej Haus Dej: Ultrafiltration piv rau Reverse Osmosis

Nov yog qee cov lus nug loj los nug koj tus kheej hauv kev txiav txim siab seb puas yog ultrafiltration lossis thim rov qab osmosis haus dej zoo tshaj rau koj:

1. Dab tsi yog TDS ntawm koj cov dej? Yog tias koj cov dej nkag los muaj qhov suav TDS siab (tshaj 500 ppm) ultrafiltration tsis pom zoo; Tsuas yog thim rov qab osmosis yuav ua tau kom tau txais TDS nqis.
2. Koj puas nyiam saj cov zaub mov hauv koj cov dej haus? (Yog tias muaj: ultrafiltration). Qee tus neeg xav tias RO dej tsis saj ntawm ib yam dab tsi, thiab lwm tus xav tias nws qab qab thiab / los yog me ntsis acidic - nws saj li cas rau koj thiab nws zoo li cas?
3. Koj cov dej siab yog dab tsi? RO xav tau qhov tsawg kawg nkaus ntawm 50 psi kom ua haujlwm zoo - yog tias koj tsis muaj 50 psi koj yuav xav tau lub twj tso kua mis. Ultrafiltration ua haujlwm zoo ntawm qhov tsis tshua muaj siab.
4. Koj puas muaj kev nyiam rau cov dej khib nyiab? Rau ib nkas loos dej RO, li 3 nkas loos mus rau qhov ntws. Ultrafiltration ua tsis muaj dej khib nyiab.
