High Efficiency Ntawm Brackish Dej Desalination, Tsawg Kev Ua Haujlwm Hauv av thiab kev ua haujlwm yooj yim

Lub hauv paus ntsiab lus thiab cov yam ntxwv ntawm txoj kev thim rov qab osmosis siv cov txheej txheem permeability xaiv los faib ib lub thawv rau hauv ob halves, thiab ntxiv cov dej ntshiab thiab dej ntsev rau ob sab ntawm daim nyias nyias tib lub sijhawm, kom cov kua theem ntawm ob sab ntawm cov dej. daim nyias nyias yog tib yam, thiab tom qab lub sijhawm dhau los, cov kua theem ntawm cov dej ntsev sab yuav nce, thiab cov kua theem ntawm cov dej ntshiab yuav poob, uas yog qhov tshwm sim ntawm kev tsiv teb tsaws ntawm cov dej molecules mus rau sab dej ntsev. los ntawm semipermeable membrane. Qhov tshwm sim no hu ua osmosis. Membranes uas xaiv permeable rau dej los yog kev daws yog hu ua semipermeable membranes. Permeation tuaj yeem nres yog tias tsim nyog siv rau cov tshuaj concentrated. Lub siab uas lub permeation ntawm ib tug dilute tov rau ib tug concentrated tov nres yog hu ua lub osmotic siab. Rov qab osmosis yog ntxiv lub siab ntau dua li ntuj osmosis ntawm ib sab ntawm cov tshuaj concentrated, thim rov qab cov kev taw qhia ntawm ntuj osmosis, thiab nias cov ions nyob rau hauv cov tshuaj mus rau lwm sab ntawm lub semipermeable membrane, uas yog contraindications rau ib txwm osmosis txheej txheem. nyob rau hauv cov xwm, yog li nws yog hu ua "Rov qab osmosis", xws li ib tug ntaus ntawv yog hu ua ib tug rov qab osmosis ntaus ntawv. Txoj kev rov qab osmosis tuaj yeem tshem tawm ntau dua 90 feem pua ​​​​ntawm cov ntsev soluble thiab ntau dua 99 feem pua ​​​​ntawm cov kab mob colloidal thiab cov organic teeb meem los ntawm dej. Piv nrog rau lwm txoj kev kho dej, nws muaj qhov zoo ntawm tsis muaj kev hloov pauv, kev ua haujlwm kub ib txwm, cov cuab yeej siv yooj yim, kev ua haujlwm siab, kev ua haujlwm hauv av tsawg, kev ua haujlwm yooj yim, tsawg zog noj, dav adaptability, siab qib ntawm automation thiab dej zoo. Tshwj xeeb, rov qab osmosis purification khoom siv los ntawm cua thiab hnub ci zog yog ib qho kev lag luam thiab txhim khu kev qha los daws cov teeb meem ntawm tib neeg cov dej hauv tsev hauv cheeb tsam uas tsis muaj hluav taws xob thiab cov pa hluav taws xob tsis txaus. Rov qab osmosis desalination tsis yog tsuas yog haum rau seawater desalination, tab sis kuj rau brackish dej desalination. Ntawm cov txheej txheem desalination uas twb muaj lawm, txoj kev thim rov qab osmosis desalination yog qhov kev lag luam tshaj plaws, thiab nws tau dhau los ntawm electrodialysis desalination txoj kev. Txij li thaum lub zog tsav ntawm cov txheej txheem thim rov qab osmosis yog qhov siab, tsis muaj qhov hloov pauv hauv cov txheej txheem, thiab daim nyias nyias tsuas yog ua lub luag haujlwm ntawm "kev tshuaj ntsuam", yog li lub zog noj ntawm cov txheej txheem rov qab osmosis sib cais yog tsawg. Ntawm cov dej hiav txwv uas twb muaj lawm thiab dej brackish desalination, thim rov qab osmosis yog lub zog tshaj plaws. Tus yam ntxwv ntawm rov qab osmosis membrane sib cais yog nws "broad-spectrum" kev sib cais, uas yog, nws tsis tsuas yog tshem tawm ntau yam ions nyob rau hauv dej, tab sis kuj tshem tawm hais tias loj tshaj ions, xws li feem ntau organics, colloids, kab mob, kab mob, raug tshem tawm, thiab lwm yam. Yog li ntawd, txoj kev rov qab osmosis sib cais tseem hu ua txoj kev sib cais dav dav.
