Kev Siv Tshuab Puas Yog Rau Koj Txoj Haujlwm?

Xaiv ntawmqhov toblim dejcov ntawvthiabdaim nyias nyiascov lim dejyog ib qho ntawm cov kev txiav txim siab tseem ceeb tshaj plaws hauv txhua txoj kev lim dej. Txawm tias koj tab tom tsim cawv txiv hmab, npias, roj noj tau, tshuaj, tshuaj pleev ib ce, lossis cov tshuaj tshwj xeeb, lub lim dej uas koj xaiv cuam tshuam ncaj qha rau qhov zoo ntawm cov khoom, kev ua haujlwm zoo, cov nqi ua haujlwm, thiab lub neej ntawm cov khoom siv.

Muaj ntau tus engineers xav tias lub lim membrane yeej ib txwm muab kev lim zoo dua vim nws muaj qhov ntsuas micron txhais. Txawm hais tias cov lim membrane yeej muab kev khaws cia cov khoom me me kom raug, lawv tsis yog qhov kev daws teeb meem zoo tshaj plaws. Qhov tseeb, kev siv lub lim membrane rau cov kua uas muaj cov khoom me me ntau feem ntau ua rau txhaws sai, nce qhov siab sib txawv, hloov pauv ntau zaus, thiab cov nqi tsim khoom siab dua. Ntawm qhov tod tes,qhov toblim dejcov ntawvzoo heev ntawm kev tswj cov khoom qias neeg loj thaum tswj cov dej ntws siab, ua rau lawv yog qhov kev xaiv zoo tshaj plaws rau kev ua kom huv thiab ua ntej lim dej hauv ntau lub lag luam.

Lo lus nug tiag tiag tsis yog"Lub lim dej twg zoo dua?"Hloov chaw, nws yog"Lub lim dej twg zoo dua rau koj cov txheej txheem tshwj xeeb?"Phau ntawv qhia no piv raukev lim dej tob vs kev lim dej membranehla cov yam tseem ceeb tshaj plaws:

Kev Nkag Siab Txog Kev Siv Tshuab Lim Dej Hauv Kev Lag Luam

Kev lim dej hauv kev lag luam tsis yog tsuas yog tshem tawm cov khoom me me ntawm cov kua xwb. Lub hom phiaj sib txawv nyob ntawm daim ntawv thov. Ib lub chaw ua cawv txiv hmab yuav xav tshem tawm cov pa phem thaum khaws cov tshuaj tsw qab. Ib lub chaw tsim tshuaj yuav xav tau kev lim dej huv uas tau lees paub. Ib lub chaw tsim roj noj tau tsom mus rau kev ua kom muaj txiaj ntsig zoo tshaj plaws thaum txo qis kev poob khoom. Vim tias cov hom phiaj no sib txawv, cov txheej txheem lim dej tau hloov pauv mus ua ob txoj hauv kev sib txawv:kev lim dej tobthiabkev lim dej membrane.

Qhov tob yog dab tsiLimCov ntawv?

Cov ntawv lim dej tob yog tsim los ntawm cov matrix tuab, porous ua los ntawm cellulose fibers, cov khoom siv lim xws li diatomaceous earth lossis perlite, thiab cov resins tshwj xeeb uas muab lub zog ntawm cov qauv thiab electrokinetic adsorption. Es tsis txhob ntes cov pa phem tsuas yog nyob rau ntawm qhov chaw, cov khoom me me raug ntes thoob plaws hauv qhov tuab ntawm cov xov xwm lim. Cov qauv peb-seem no tso cai rau lub lim kom khaws cov pa phem ntawm ntau qhov ntau thiab tsawg thaum tswj cov nqi ntws ruaj khov rau lub sijhawm ntev dua.

Vim tias cov khoom tsis huv tau faib thoob plaws hauv cov xov xwm es tsis yog sib sau ua ke ntawm ib qho chaw, cov ntawv lim dej tob muaj peev xwm tuav cov av zoo heev. Lawv siv dav rau kev ua kom cov dej haus, cov roj noj tau, cov kua zaub fermentation, cov enzymes, gelatin, cov tshuaj pleev ib ce, thiab cov tshuaj zoo.

Cov Lim Membrane Yog Dab Tsi?

Cov lim dej membrane siv cov ntaub nyias nyias polymeric nrog cov qhov loj me uas tswj tau zoo heev. Tsis zoo li cov lim dej tob, cov lim dej membrane feem ntau vam khom raukev lim dej saum npooCov khoom me me uas loj dua qhov loj ntawm qhov pore yuav khaws cia rau ntawm qhov chaw ntawm daim nyias nyias, thaum cov khoom me me hla dhau. Cov ntaub ntawv membrane feem ntau suav nrog PES, PVDF, Nylon, PTFE, thiab cellulose acetate, nrog rau qhov loj ntawm qhov pore feem ntau yog txij li 0.1 txog 1.0 μm rau microfiltration.

Lawv lub peev xwm los xa cov khoom khaws cia tag nrho ua rau cov lim dej membrane zoo tagnrho rau kev lim dej kom huv, tshem tawm cov kab mob me me, thiab cov kauj ruam lim dej kawg tseem ceeb uas qhov kev sib xws thiab kev ua raws li txoj cai yog qhov tseem ceeb.

Txhua Lub Tshuab Lim Dej Ua Haujlwm Li Cas

Txoj Cai Lim Qhov Tob

Xav txog seb koj nchuav dej av nplaum rau hauv ib daim phuam tuab. Thaum cov kua dej ntws mus rau hauv daim phuam, cov khoom me me raug ntes rau ntawm qhov tob sib txawv es tsis yog tsuas yog sib sau ua ke rau ntawm qhov chaw xwb.
