Hauv lub ntiaj teb ntsib kev caws pliav ntws tawm, dej hiav txwv loj rau dej tshiab tau hloov los ntawm kev npau suav rau qhov tseeb. Raws li txoj kev tseem ceeb rau augmenting dej muab, desalination thev naus laus zis yog tau txais kev saib xyuas tsis tau ua. Tam sim no, peb cov txheej txheem tseem ceeb yog coj txoj kev thoob plaws hauv lub hiav txwv rau hauv kub: Ntau theem flawillation (MSF), thiab dej hiav txwv otmosis (swro). Kab lus no yuav muab cov kev tsom xam ntawm peb txoj kev siv no thiab sib tham txog lawv cov qauv kev txhim kho.
Tsoos Kev Ua Si Cov Txheej Txheem: Qhov Kev Xaiv Ruaj Ntseg thiab Txhim Kho
Thermal cov txheej txheem yog thawj zaug desalination thev naus laus zis yuav tsum tau siv nyob rau ntawm nplai loj. Lawv txoj ntsiab cai cuam tshuam nrog dej hiav txwv cua sov kom ua rau evaporation, ces condensing lub chav kom tau cov dej tshiab, yog li ua tiav ntsev-dej sib cais.
Tsawg-kub muaj ntau cov nyom nti (lt-me)
Qhov tsawg-kub-muaj cov txheej txheem distillation distillation tuaj yeem raug saib raws li qhov kev ntsuas ntawm cov txheej txheem evaporation thiab cov khaub ncaws hws kom rov qab ua ntau zaus ntawm cov evaporators ntau dua. Nws cov ingenuity lies nyob rau hauv qhov tseeb tias lub chav tsim nyob rau hauv lub ntej evaporator ua qhov ua kom sov rau ib qho, ua tiav ib tug cascaded siv ntawm lub zog thermal. Tus txheej txheem no feem ntau ua haujlwm nyob rau hauv qis dua cov teeb meem ntawm kev sib cav thiab corrosion hauv cov kav dej siv nyiaj, ua rau cov khoom siv tau ntev dua thiab kho tau yooj yim. Tsis tas li ntawd, LT-med technology yog zoo-haum rau cov khoom siv cua sov txo qis, thiab muab nws cov kev xaiv hluav taws xob, ua rau cov phiaj xwm tseem ceeb rau cov dej num tshiab khiv.
Ntau-theem nyem (MSF)
Ntau theem theem thev naus laus zis yog ib zaug tus huab tais hauv daim teb desalination, nrog tshwj xeeb thoob plaws hauv Middle East. Nws txoj hauv paus ntsiab lus cuam tshuam nrog dej hiav txwv rhuab rau hauv cov chaw flawbers nrog kev txo qis qis, ua rau dej hiav txwv txo qis "flash" tshwm sim. Cov pa roj vaporized yog ces condensed kom dhau los ua dej tshiab. MSF Technology yog paub tab, ruaj khov, thiab txhim khu kev qha rau kev ua lag luam, thiab tsim nyog rau tsim ultra-loj-teev desalination tej yaam num. Txawm li cas los xij, nws qhov kev tsis txaus siab kuj tau tshaj tawm, yog tias kev siv hluav taws xob ntau thiab nce kev siv hluav taws xob, txuas nrog qhov tsis muaj kev ua haujlwm. Qhov no tau ua rau nws txo qis nws kom zoo dua ntawm nthwv dej tshiab ntawm kev ua lag luam kev ua lag luam, nrog nws cov lag luam sib qhia tau hloov zuj zus los ntawm lwm cov thev naus laus zis.
Lub kiv puag ncig ntawm membrane cov txheej txheem: sawv ntawmDej Hiav Txwv Ncej Qab Zib
Tag nrho txawv ntawm cov txheej txheem thermal, qhov tseem ceeb ntawm daim nyias nyias ntawm cov txheej txheem yog "sieving." Dej hiav txwv tseem ceeb tshaj osmosis yog cov sawv cev sawv cev ntawm pawg no. Nws txoj hauv paus ntsiab lus cuam tshuam nrog lub siab rau ntawm ntug dej hiav txwv uas muaj ntau dua cov seewaters kheej osmotic siab. This forces water molecules to "squeeze" through a special, selective semi-permeable membrane, while impurities such as salts, heavy metals, and microorganisms are rejected by the membrane.
Raws li tam sim no tsis tseem ceeb hauv kev ua lag luam thoob ntiaj teb, kev ua tiav ntawm dej hiav txwv Osmosis system yog ntaus nqi rau nws cov txiaj ntsig zoo tag nrho. Piv rau cov txheej txheem thermal, nws lub zog tau siv hluav taws xob qis dua, thiab cov neeg muaj npe nrov ntawm lub zog rov qab thev naus laus zis, nws tus nqi khiav haujlwm txuas ntxiv mus. Tib lub sijhawm tsim kho, nws muaj ib lub sijhawm tsim kho me me, kev ua haujlwm yooj yim dua thiab kho tau yooj yim thiab nws tuaj yeem tsim qauv raws li kev thov.
Taihe ib puag ncig tau mob siab rau hauv daim teb no tau ntau xyoo, ua rau muaj ntau xyoo, tshwj xeeb hauv kev sib xyaw thiab cov khoom muaj zog ro ro desalination nroj tsuag. Los ntawm kev siv cov txheej txheem sib txawv los tiv thaiv cov tub ntxhais tseem ceeb, peb tau txais txiaj ntsig zoo, thiab cov dej hiav txwv kom loj, thiab cov dej hiav txwv loj
Kev sib piv ntawm peb cov txheej txheem thiab yav tom ntej saib xyuas

Saib tom ntej, cov toj roob hauv pes ntawm desalination thev naus laus zis yog ua kom pom tseeb. MSF Technology yuav ua ntau ntau ua haujlwm raws li cov nroj tsuag legacy. LT-med, nrog nws cov txiaj ntsig zoo nrog kev cog lus, tseem yuav tuav ib thaj chaw tshwj xeeb hauv cheeb tsam. Txawm li cas los xij, tsis muaj kev ntseeg tias cov txheej txheem sib npaug yog txuas ntxiv ntawm kev pom ntawm cov txheej txheem txheej txheem. Nrog rau kev sib txuas txuas ntxiv hauv membrane cov khoom siv science, xws li kev txhim kho hauv cov tshuab tshuaj tiv thaiv kab mob thiab tiv thaiv oxidation thiab cov nqi tiv thaiv kev nce qib ntxiv, thiab nws cov nqi yuav txo qis. Nyob rau yav tom ntej, tsim kev ua haujlwm siab, cov tshuaj muaj zog tshaj plaws rau kev daws cov ntug dej hiav txwv hauv cov ntug hiav txwv thiab kob loj, nrog kev ua tau zooDej Hiav Txwv Ncej Qab ZibUa neeg tsis ntseeg qhov tseem ceeb thiab tus yuam sij rau nws txoj kev vam meej.
