Kev Ntsuas Cov Txheej Txheem Rau Hollow Fiber Membrane Module
Dec 06, 2025| Kev sim cov txheej txheem rau hollow fiber membrane modules tsom rau lawv cov physicochemical zog thiab kev sib cais / permeability kev ua tau zoo. Cov kev ua haujlwm tseem ceeb muaj xws li porosity, pore loj faib, lub zog tensile, siab tsis kam, flux decay rate, rejection rate, hydrophilicity, chemical resistance, thiab thermal stability. Flux thiab tsis lees txais tus nqi yog qhov tseem ceeb ntawm kev sib cais kev ua tau zoo.
Thaum kuaj flux thiab tsis lees paub tus nqi, cov txheej txheem tuaj yeem muab faib ua cov txheej txheem siab sab hauv thiab sab nraud raws li kev coj ua kua dej ntws, thiab hla - ntws thiab tuag- txoj hauv kev kawg raws li cov qauv ntws. Yog li ntawd, cov qauv kev sim muaj xws li sab hauv siab hla- txoj kev ntws, sab nraud siab hla- txoj kev ntws, sab hauv siab tuag- txoj kev kawg, thiab sab nraud siab tuag- txoj kev kawg. Cov mis rau kev xam cov membrane flux (J) yog J=V / (S * t), qhov twg V yog qhov permeate ntim, S yog thaj tsam membrane zoo, thiab t yog lub sijhawm. Cov mis rau xam qhov tsis lees paub tus nqi (R) yog R=(1 - C1/C0) * 100%, qhov twg C0 yog qhov pub concentration thiab C1 yog qhov permeate concentration.
Cov kev sim no ua raws li ntau lub teb chaws tus qauv, xws li GB/T 40258-2021 "Kev Ntsuam Xyuas Txoj Cai rau Corrosion Resistance of Hollow Fiber Membranes to Chemical Cleaning Agents", GB/T 38902-2020 "Kev Txiav Txim ntawm Hla{- Kev Ntsuas Membranes ntawm Hollow Membranes" GB / T 38511-2020 "Kev Ntsuam Xyuas Txoj Cai rau Kev Pabcuam Lub Neej ntawm Hollow Fiber Membranes", GB / T 42281-2022 "Hollow Fiber Membrane Modules rau Membrane Aerated Biofilm Reactors (MABR)", HG / T 5111-2016 thiab cov tshiab Hollow Fiber-2016 Module", thiab lwm yam.
