Dab tsi yog cov tshuaj lim dej tshem tawm ntawm cov dejThiab vim li cas cov teeb meem no rau koj txoj kev noj qab haus huv?
Kev tiv thaiv kev ua haujlwm hauv nroog tiv thaiv microbial hawv, muaj ntau txhiab tus kws tshuaj suav, thiab kev siv tshuaj tua kab, thiab ua kom muaj zog ua ke hauv cov tshuab faib khoom uas tau faib. Carbon Filtration technology Qhov sib pauv no los ntawm kev tshaj tawm cov txheej txheem uas muaj cov tshuaj paug tsis huv rau cov qauv carbon. To kev nkag siab dab tsi Dag cov roj carbon lim tawm vim li cas ntau lab tus qauv ntawm cov tsev neeg thiab kev lag luam cia siab rau qhov kawg- theem limificate.
Qhov kev tshuaj xyuas no dissects filtration mechanisms, cov ntsiab lus xa tawm thoob plaws cov chaw nyob, thiab kev daws teeb meem kev coj ua rau kev ua tau zoo. Pov thawj -} Raws cov kev nkag tau siv cov neeg siv khoom siv los xaiv cov qauv tsim nyog thiab ua kom ntau dua cov khoom siv paug.
Cov tshuaj paug twg adsorptment chemistry tshem tawm?
Puas yog cov pa roj carbon monoxide tsom cov kuab paug?
IbUa kom tau cov dej limKev khiav haujlwm los ntawm cov van der wawals rog thiab cov tshuaj lom neeg nruab nrab ntawm cov pa carbon chaw thiab organic molecules. Ua kom - pa dej ntawm 600 {}}}}}}}}} 9,000-1 surface surface areas areas areas້ນ nce mus txog 1,000-1,500 m² / g. Qhov qauv me me no ntxiab cov khoom ua paug los ntawm:
- Lub cev Adsorption: Lwg me me ua raws li cov phab ntsa uas muaj hluav taws xob
- Tshuaj Yeeb Nkab: Pawg ua haujlwm rau cov pa roj carbonural daim ntawv cog lus kev sib ntaus sib tua nrog cov pa paug
- Kev lim tshuab: Cov ntsiab lus loj dua Lodge nyob rau hauv Pore Cov Qauv (Thib Ob Lub Tshuab)
Cov tshuaj tau zoo:
Chlorine thiab chloramines
Cov kab mob sib tsoo (0.5-4 mg / l Cov pa roj carbon txo cov tshuaj lis ntshav los ntawm 95% + thiab chloramines los ntawm 50-70%, txawm hais tias qhov kawg yuav tsum tau muaj catalytic carbon lossis ncua sijhawm.
Volatile organic compounds (vocs)
Muaj cov kuab cua {- Benzene, perchlorethylene, perchlorethylene {{leh {leach los ntawm kev tso tsheb hlau luam cia khoom thiab chaw tsim khoom. EPA Feem Ntau Cov Hom Kab Mob Ntau Tshaj Plaws (MCLS): 5-70 μg / u nyob ntawm compound. Carbon ua tiav 80-99% kev tshem tawm rau cov vocs feem ntau.
Tshuaj tua kab thiab tshuaj ntsuab
Tshuaj lom neeg ua liaj ua teb (Atrazine, 2,4-D, glyphosate) cov av tsis huv. Cov pa roj carbon ua tau zoo sib txawv: 60-95% rau chlorinated tshuaj tua kab, 40-80% rau cov tshuaj ntsuab polar. Molecular loj thiab polarity txiav txim siab los ntawm ib qho affinity.
Chaw nyob seem
Tshuaj tua kab mob, cov tshuaj hormones, thiab analgesics nkag mus hauv cov dej tawm. Ntau: 10-1,000 ng / l. Carbon tshem tawm 50-90% ntawm cov tshuaj uas ib txwm muaj (ibuprofen, acetaminophen), txawm hais tias qee qhov sib txuas (metformin) tiv thaiv adsorption.
Saj thiab tsw ntxhiab
Geosmin and 2-methylisoborneol (MIB) from algae create earthy flavors at 5-10 ng/L concentrations. Carbon eliminates these at >95% kev txuag nyiaj vim muaj zog organic affinity.
Tom qab muaj kev sib raug zoo?
Inorganic cov zaub mov thiab cov ntsev
Calcium, magnesium, sodium, thiab tshuaj fluoride dhau los ntawm carbon tsis hloov pauv. Cov lus no yaj uas tsis muaj cov pa roj hmab los. Dej hardness (100-300 mg / u li caco₃) thiab tag nrho cov khib nyiab yaj (TDS) tas li.
Cov hlau hnyav
Txhuas, arsenic, mercury, thiab chromium yuav tsum tau tshwj xeeb xov xwm. Txheem Granular ACTIVATED cov pa roj carbon (GAC) tshem tawm 10-30% dhau los ntawm kev teeb meem ntawm kev teeb meem. Kev Zam: Catalytic cov pa roj carbon monoxide qhia txog pH 6-8.
Cov kab mob me me
Cov kab mob (E. COLI, LAUG LEGENDA), kab mob, thiab proozoz cyst (Cryptosporidium, giardia) yuav tsum tau tua kab lossis ncauj {potron pom. Cov pa pa roj carbon paus (0.5-50 μm) tso cai pathogen tso, txawm hais tias qee cov tshuab khaws cia tshwm sim hauv cov roj carbon blocks.
Nitrates thiab Nitrites
Agricultural tso tawm dej (5-50 mg / l) muaj mob rau cov pa roj carbon. Ion pauv pauv lossis thim rov qab osmosis tsim nyog rau kev tshem tawm.
Nyob rau hauv cov teeb meem twg carbon filtrationed?

Xaus Lus: Puas yog cov tshuaj carbon filtration muab kev tiv thaiv?
To kev nkag siab tias cov lim dej carbon tshem tawm ntawm cov dej kom paub meej ob lub peev xwm thiab kev txwv. Cov kab ke no Excel ntawm cov organic compound rovuction- chlorine, vocs, kev tshem tawm rau cov phiaj xwm kev ua kom muaj lub hom phiaj paug. Txawm li cas los xij, lawv swb tiv thaiv yaj cov minerals, cov hlau hnyav (tsis muaj xov xwm tshwj xeeb), thiab cov kab mob sib luag.
Kev xa tawm zoo yuav tsum tau txuam nrog cov hom carbon ntaus (gac tiv thaiv carbon block), lub sij hawm muaj peev xwm, thiab hloov muaj peev xwm cov dej sib tw tshwj xeeb. Txawm hais tias kev tiv thaiv cov txheej txheem hauv tsev neeg lossis txhawb nqa cov lim dej, tshuab cov roj carbon ua haujlwm ua rau muaj kev daws teeb meem.
Kev tu ib txwm - Thaum muaj kev kho kom zoo, paug tiv thaiv kev ua tau zoo thiab tiv thaiv kev pheej hmoo thiab kev ua haujlwm tsis txaus ntseeg.
