Hauv kev ua haujlwm ntawm thim rov qab Osmosis Desalination Cog, Membrane fouling ncaj qha cuam tshuam kev cuam tshuam system ncaj qha thiab cov nqi ua haujlwm. Raws li cov tseem ceeb tivthaiv ntawmDesalination Ro System, cov zaub mov tso tawm ntawm daim nyias nyias nyob hauv nws qhov hws ua rau Flux poob qis, ntau zog siv hluav taws xob, thiab txawm tias membrane tsis ua hauj lwm. Kab lus no tsom rau cov kev tsim qauv, kev cuam tshuam, thiab kev pab txhawb rau cov kev sib tw tseem ceeb rau cov kev sib tw tseem ceeb no.
I. Tsim kev mechanisms thiab kev faib tawm ntawm Membrane fouling
Membrane fouling fundamentally tshwm sim los ntawm cov physicochemical deposter los yog cov tshuaj tua pov tseg rau ntawm daim nyias nyias. Thaum lub sij hawm desalination ro system ua haujlwm, siab-salinity Feedwater txheej muaj kev pom zoo-tsav qhov chaw, tsim ib puag ncig zoo rau kev ua paug. Raws li cov khoom muaj nqis, fouling tuaj yeem faib ua peb pawg:
1. Particulate fouling
Tshem tawm cov nplais (piv txwv li, silt, microbial seem) tsis tau cuam tshuam txhua lub sijhawm ua ntej lim lim dej qab zib lim rau ntawm daim nyias nyias.
2. Colloidal fouling
Colloidal tshuaj (piv txwv li, silicates, humic acids) nrog particle qhov ntau thiab tsawg}. 00 μm. €}. Cov kev paug no feem ntau yog latent thiab feem ntau yuav tsum tau electron me me rau kev txheeb xyuas.
3. Cov ntxhib ntxig
Cov pa roj carbonates lossis cov sulfates ntawm calcium, magnesium, thiab lwm yam li ua ntej nyob rau hauv Supersine nyob rau ntawm Supersine Sab, Txoj Kev Rigid Crystalline Cov Qauv. Thaum cov Langelier salitation index (LSI) ntawm lub mloog zoo tshaj 1.5, qhov kev pheej hmoo ntawm calcium carbonate surging surges surges surges surges, muaj peev xwm ua rau membrane Pore thaiv cov nqi tsawg dua 60%.
Ii. Compound cuam tshuam ntawm fouling ntawm kev ua haujlwm
1. Flux poob
Fouling txheej nce hydraulic tsis kam, txo tus txivlucing flux. Raws li IDA 2024 cov lus ceeb toom txhua xyoo, raws li cov xwm txheej ntawm kev haus dej ntau dhau los haus ntau dua li 30% nce mus txog 30% -50%.
2. Kev Siv Zog Siv EPALATION
Tswj cov dej tsim tau cov dej tsim tau yuav tsum tau nce qib kev ua haujlwm, nrog cov ntxh luam cov ntxhwb los ntawm kev siv lub zog hluav taws xob.
3. Mahabban Lifespan Luv
Biodegradation inducions los ntawm colloidal fouling corrodes membrane cov ntaub ntawv, thaum cov teeb meem abrasive cuam tshuam los ntawm particulates accelerate nto kev puas tsuaj.
III. Kev Tiv Thaiv Kev Tiv Thaiv Kev Tiv Thaiv thiab Tu Technology
1. Txhim Kho Pretricement
- Ntau hom teeb meem:Ultrafiltration (UF) + Tau ua kom cov txheej txheem carbon adsorption ua tiav 95% colloidal tshem tawm, ruaj khov silt sit index (sdi) hauv qab 2. {}.
- Tshuaj lom neeg muaj yees duab:Dosing nplai inibitors (piv txwv li, polyacrylic acid-based tebcom) cuam tshuam crystallization cov txheej txheem. Nyob rau hauv ceramic membrane cov ntawv thov, cov khoom siv los ntawm Shandong Taihe kev tiv thaiv ib puag ncig withst acid \/ alkali ntxuav, txo cov tshuaj lom neeg los ntawm fouling.
2. Txawj Ntse Tu Technologies
- Online soj xyuas thiab ceeb toom thaum ntxov:Kev tshuaj xyuas lub sijhawm tiag tiag ntawm transmembrane siab (ΔP) thiab li qub flux ua kom haum kev txiav txim siab txog sijhawm.
- Graded Tu Lub Tswv Yim:
- Siv lub cev: Air-dej mem tes thev naus laus zis cabration teebmeem los tshem tawm cov dej paug thim rov qab.
- Kev Tu Kom huv: Customized Cov Tshuaj Tiv Thaiv Kev Nyab Xeeb rau hom foulding, xws li citric acid rau inorganic acides thiab surfactants rau cov pa phem.
IV. Tawg nyob rau hauv engineering cov kev sib tw
Composite fouling tseem yog qhov kev sib tw tseem ceeb hauv ro system ua haujlwm. Ntawm 2019 thiab 2024, Ntau Rov Qab Osmosis Desalination Nroj tsuag hauv Boha Rim Thaj Chaw Ua tiav Flux Rov qab los ntawm Enzymatic Tu Siab Technologies.
V. Taihe Kev tiv thaiv ib puag ncig cov thev naus laus zis thev naus laus zis
Txo kev cia siab rau cov neeg tsis raug cov neeg tsis pub muaj neeg ua yeeb yam ntawm membrane Technology
Nyob rau hauv seasurater desalination los yog high-salinity lim dej, Taihe tus ceramic Membrane Technology yog feem ntau ua ke nrog Desalination Ro Tshuab ua ib kauj ruam ro system ua ib kauj ruam retricate kauj ruam. Los ntawm kev txhim kho pretreatment efficiency, nws txo cov kab ke ro systemnentence on nplai incharitors. Piv txwv li, nwsCeramic Desalination Membranes (30 nm pore loj) cuam tshuam cov khib nyiab thiab colloids feem ntau, txo qis tom qab rou rou rou rouling txaus ntshai.
Membrane fouling tswj yog central rau cov haujlwm tau zoo ntawm kev ua haujlwm ro systemCov. Los ntawm pretreaticment optimization rau cov ntse tu tshuab, kev lag luam tau tsim muaj ntau txoj kev tiv thaiv kev ua haujlwm. Nrog kev txo qis ntxiv hauv cov nqi ua haujlwm, thim cov nroj tsuag Osmosis desalination yuav muab cov kev txhawb nqa dej kom zoo rau cov cheeb tsam dej hiav txwv.
