Seawater Desalination Membrane

Seawater Desalination Membrane

Nqe lus piav qhia:

Dej tsis txaus yog qhov teeb meem thoob ntiaj teb uas xav tau cov kev daws teeb meem tshiab. Seawater desalination tau tshwm sim los ua cov thev naus laus zis tseem ceeb kom ua tau raws li qhov xav tau ntau ntxiv rau cov peev txheej dej tshiab. Kev vam meej ntawm seawater desalination nyob ntawm qhov ua tau zoo thiab kev ua tau zoo ntawm daim nyias nyias siv hauv cov txheej txheem. Ob lub tswv yim tseem ceeb ntawm daim nyias nyias uas tau txais kev nyiam yog seawater desalination membranes thiab thim rov qab osmosis membranes.

Seawater desalination membranes thiab thim rov qab osmosis membranes yog ob qho tib si ua haujlwm hauv cov nroj tsuag desalination cais ntsev thiab lwm yam impurities los ntawm seawater. Txawm li cas los xij, lawv txawv ntawm cov qauv, muaj pes tsawg leeg, thiab kev ua haujlwm. Kev nkag siab txog qhov sib txawv no yog qhov tseem ceeb rau kev xaiv cov txheej txheem membrane zoo rau cov ntawv thov tshwj xeeb.

Seawater Desalination Membrane:

Seawater desalination daim nyias nyias yog tsim tshwj xeeb rau cov mob hnyav thiab qib siab salinity ntsib hauv cov nroj tsuag desalination. Cov membranes no yog tsim los ntawm ntau yam ntaub ntawv, xws li cellulose acetate, polyamide, thiab polysulfone. Lawv muaj cov txheej txheem tuab dua piv rau cov rov qab osmosis daim nyias nyias, ua rau lawv tiv taus cov kev ntxhov siab uas yuav tsum tau ua rau desalination.

Ib qho txiaj ntsig tseem ceeb ntawm seawater desalination membranes yog lawv lub peev xwm los tiv thaiv fouling. Fouling tshwm sim thaum cov khoom me me accumulates ntawm daim nyias nyias, txo nws cov efficiency. Qhov tshwj xeeb muaj pes tsawg leeg ntawm seawater desalination membranes tiv thaiv fouling, kom ntseeg tau tias kev ua tau zoo thiab txhim khu kev qha nyob rau lub sijhawm ntev.

Reverse Osmosis Membrane:

Rov qab osmosis daim nyias nyias yog siv dav hauv ntau daim ntawv thov, suav nrog kev desalination, kev kho dej khib nyiab, thiab kev ua kom huv. Cov daim nyias nyias no feem ntau yog tsim los ntawm cov ntaub ntawv nyias-zaj duab xis, uas muaj cov txheej txheem nyias nyias tso rau ntawm cov khoom siv txhawb nqa. Cov txheej nyias nyias ua kom muaj cov dej ntws siab thaum tswj xyuas cov peev txheej zoo tshaj plaws ntawm kev tsis lees paub ntsev.

Piv rau seawater desalination daim nyias nyias, thim rov qab osmosis daim nyias nyias muaj qhov cuam tshuam rau fouling vim lawv cov txheej txheej nyias nyias thiab cov pores me me. Txawm li cas los xij, kev nce qib hauv cov txheej txheem membrane tau ua rau kev txhim kho cov txheej txheem tiv thaiv fouling thiab txhim kho cov txheej txheem tu, txo cov teeb meem ntsig txog fouling.

Kev sib piv kev ua haujlwm:

Thaum xav txog seawater desalination lossis thim rov qab osmosis membrane tshuab, ntau yam tuaj yeem ua si. Qhov kev xaiv feem ntau yog nyob ntawm cov kev cai tshwj xeeb ntawm daim ntawv thov.

Seawater desalination membranes zoo nyob rau hauv high-salinity ib puag ncig thiab tiv taus fouling. Lawv muab cov txiaj ntsig zoo ntawm cov ntsev tsis lees paub, ua kom cov dej tsis huv nrog cov ntsev tsawg. Qhov no ua rau seawater desalination membranes zoo tagnrho rau cov chaw ntug dej hiav txwv ntsib cov dej tsis txaus, qhov twg seawater yog thawj qhov dej.
