Tsis yog. Ultrafiltration (UF) thiab reverse osmosis (RO) yog cov tshuab kho dej muaj zog thiab ua haujlwm tau zoo, tab sis UF txawv ntawm RO hauv ntau txoj kev tseem ceeb:
Lim cov khoom khov/cov khoom me me li 0.02 microns, suav nrog cov kab mob bacteria. Tsis tuaj yeem tshem tawm cov zaub mov uas yaj, TDS thiab cov khoom yaj hauv dej.
Tsim dej raws li qhov xav tau - tsis tas yuav muaj cov thoob dej cia khoom
Tsis muaj dej khib nyiab tsim tawm (txuag dej)
Khiav tau zoo ntawm qhov hluav taws xob tsawg - tsis tas yuav siv hluav taws xob
Qhov txawv ntawm ultrafiltration thiab reverse osmosis yog dab tsi?
Hom thev naus laus zis membrane
Ultrafiltration tsuas yog tshem tawm cov khoom me me thiab cov khoom khov, tab sis nws ua li ntawd ntawm qib microscopic; qhov loj ntawm daim nyias nyias yog 0.02 microns. Hais txog saj, ultrafiltration khaws cov zaub mov, uas cuam tshuam rau qhov saj ntawm cov dej.
Qhov rov qab osmosis tshem tawm yuav luag txhua yam hauv dej, suav nrog feem ntau cov zaub mov uas yaj thiab cov khoom khov uas yaj. RO daim nyias nyias yog cov daim nyias nyias semipermeable nrog qhov loj me ntawm kwv yees li 0.0001 microns. Yog li ntawd, dej RO yuav luag "tsis muaj ntxhiab" vim nws tsis muaj cov zaub mov, tshuaj lom neeg, thiab lwm yam organic thiab inorganic compounds.
Muaj ib txhia neeg nyiam lawv cov dej kom muaj cov zaub mov (los ntawm UF), lwm tus nyiam lawv cov dej kom huv si thiab tsis muaj ntxhiab (los ntawm RO).
Ultrafiltration muaj ib daim nyias nyias hollow fiber, yog li nws yog ib qho lim dej zoo heev uas thaiv cov khoom me me thiab cov khoom khov.
Reverse osmosis yog ib qho txheej txheem uas cais cov molecule. Nws siv ib daim nyias nyias semi-permeable los cais cov inorganics thiab cov inorganics yaj ntawm cov molecule dej.
HAUVdej nag/Tsis lees txais
Ultrafiltration tsis tsim cov dej khib nyiab (cov khoom pov tseg) thaum lub sijhawm lim dej *
Hauv kev siv reverse osmosis, muaj kev lim dej hla mus los ntawm daim nyias nyias. Qhov no txhais tau tias cov dej ntws (dej nkag mus rau hauv/cov dej tsim tawm) nkag mus rau hauv lub tank cia thiab cov dej ntws uas muaj txhua yam khoom tsis huv thiab cov khoom tsis muaj sia (cov khib nyiab) nkag mus rau hauv qhov dej ntws. Feem ntau, rau txhua 1 nkas loos dej reverse osmosis uas tsim tawm, 3 nkas loos raug xa mus rau qhov dej ntws.
Nruab
Kev txhim kho lub kaw lus osmosis rov qab xav tau ob peb qhov kev sib txuas: cov kav dej, cov kav dej tso dej khib nyiab, cov thoob dej cia khoom, thiab cov kais dej sib txawv.
Kev teeb tsa ib lub tshuab lim dej ultrafiltration nrog cov membranes uas tuaj yeem yaug tau (qhov tshiab tshaj plaws hauv kev siv tshuab ultrafiltration*) xav tau ob peb qhov kev sib txuas: ib txoj kab xa khoom noj, ib txoj kab ntws rau kev yaug cov membranes, thiab ib lub qhov dej tshwj xeeb (kev siv dej haus) lossis txoj kab xa khoom tawm (kev siv rau tag nrho lub tsev lossis kev lag luam).
Yuav kom txhim kho lub tshuab lim dej ultrafiltration uas tsis muaj cov membranes uas yoo ntxuav tau, tsuas yog txuas lub tshuab rau cov kab xa dej thiab cov kais dej tshwj xeeb (dej haus tau) lossis cov kab xa dej tawm (tag nrho cov kev siv hauv tsev lossis kev lag luam).
Qhov twg zoo dua, RO lossis UF?
Cov txheej txheem reverse osmosis thiab ultrafiltration yog cov txheej txheem zoo tshaj plaws thiab muaj zog tshaj plaws. Thaum kawg, qhov twg zoo dua yog qhov koj nyiam raws li koj cov dej, saj nyiam, qhov chaw, kev xav txuag dej, lub zog dej, thiab lwm yam.
Muaj yog lub RO lim dej thiab UF lim dej rau koj xaiv.
