Ultra tacewa (UF)

Ultrafiltration ne tsari na matsin lamba a matsayin mota, ta amfani da ultrafilter membrane daban-daban apertures raba ƙarancin ruwa. An ci gaba da fasahar ultrafiltration ta kasar Sin a farkon shekarun 1970, ana amfani da kayan aikin CA tubular membrane na farko don masana'antar electrophoresis, sannan kuma don daidaitawa da kayan aikin enzyme.

A. Ka'idodin Ultrafilter

Ultrafiltration ne wani membrane raba fasaha, da membrane ne porous asymmetric tsari. tacewa tsari ne mai matsa lamba bambanci a bangarorin membrane a matsayin drive karfi, mafita raba tsari tushen inji siffa ka'idar, amfani da matsa lamba ne yawanci 0.1-0.3M p a, micropore aperture na ultra tacewa membrane

Kimanin tsakanin 0.005-1μm, nauyin kwayoyin da aka tsare yana tsakanin 1,000-500,000 daltons, saboda haka an yi la'akari da tsarin raba membrane mai ultrafiltration a matsayin tsarin raba jiki mai sauki.Akwai yanayi uku na tsarin ultrafiltration:

1) Solvent samar da adsorption (daya adsorption) a kan membrane farfajiyar da kuma micropore bangon.

2) Girman ƙwayoyin da aka narkar ya yi kama da abubuwan da ke cikin membrane, kuma an tsare abubuwan da aka narkar a kan membrane surface ta hanyar inji don cimma siffa (toshewa).

3) Diameter granules na narkewa ne mafi girma fiye da membrane aperture, da narkewa a membrane farfajiyar da inji tsare, cimma screening

2. siffofin Ultrafilter fim

Ultrafiltration da reverse osmosis duka suna da matsin lamba a matsayin mota, suna da irin wannan membrane kayan da kuma irin wannan shirye-shirye hanyoyin, suna da irin wannan tsari da ayyuka, da kuma irin wannan aikace-aikace

3. Micro tacewa (MF)

Microfiltration ne wani tacewa fasaha, shi ne kewayon buri yau da kullun 0.1-10μm, tsakanin yau da kullun tacewa da ultrafiltration.

1. Micro tacewa ka'ida

Micro tacewa ne da radius matsin lamba bambanci a matsayin motar karfi (aiki matsin lamba 0.7-7k PA), amfani da "screening" rawar na screen-siffa tacewa kafofin watsa labarai membrane raba membrane tsari, da ka'idar da m ta hanyar tacewa, amma micro tacewa aperture a 0.1-10μm, saboda haka kuma aka kira tacewa, shi ne sabon ci gaban tacewa fasaha.

Matsayin tsarin tsare microfilter membrane yana da bangarori masu zuwa:

1) Mechanical tange tasirin manyan abubuwa membrane yana da tasirin tange girma fiye da shi aperture ko daidai da aperture da sauran ƙarancin abubuwa.

2) Tasirin jiki ko tasirin jarraba shan idan an jaddada tasirin sosai zai sami sakamakon da ba ya dace da ainihi, ban da la'akari da abubuwan da ke cikin aperture, a la'akari da tasirin wasu abubuwa, gami da tasirin shan da kuma aikin lantarki.

3) Za a iya lura da tasirin gada ta hanyar electroscope, a ƙofar rami, za a iya cutter kwarara saboda tasirin gada.

2. Bambanci tsakanin microfiltration da ultrafiltration, yau da kullun tacewa

Microfiltration, ultrafiltration da reverse osmosis duk suna da matsin lamba a matsayin motsi don cimma burin rabuwa da tarihi, duk suna da canje-canje na musamman da canja wurin ingancin dubawa. Microporous tacewa film da aka yi amfani da microporous tacewa membrane na rami tsari nau'in siffa, shi ya tsare particles mafi girma fiye da ultra tacewa (babu wani m rabuwa tsakanin biyu), za a iya tace ruwa ko 0.1-10um particles a cikin jikinsa, kamar kwayar cuta, kwayoyin cuta, colloids, da dai sauransu. Matsin lamba na aiki yawanci ƙasa da 0.2MPa.

Nano tacewa (NF)

Nanofilter wani sabon fasahar raba membrane ne tsakanin reverse osmosis da ultrafiltration. Yana da kwayoyin nauyi sama da 200g / mol, kwayoyin girman 1nm da narkewa bangare membrane tsari, saboda haka an kira shi "nano tacewa", da membrane da ake kira "nano tacewa membrane", aiki matsin lamba ne yawanci 0.5-1.0MPa, yawanci a kusa da 0.7MPa, a ƙananan 0.3MPa. Wannan siffar, wani lokacin ana kira nano tacewa "low matsin lamba reverse osmosis" ko "conveyor reverse osmosis". Ci gaban nano tacewa membrane fara a 1970s, da manufar ci gaban shi ne ta yi amfani da membrane hanyar maye gurbin al'ada lime hanyar da kuma ion musayar hanyar softening tsari, nano tacewa membrane farkon kuma aka sani da softening membrane amfani ne aiki low matsin lamba, a kan ruwa softening, low molecules na dabi'u abubuwa rabuwa, kawar da gishiri da sauransu da kuma m amfani.
