Yakasiyana-siyana membrane zvinhu zvinoshandiswa muindasitiri yekurapa mvura, uye izvo zvinowanzoitika ndeye ultrafiltration membranes uye reverse osmosis membranes. Zvese zviri zviviri ultrafiltration membranes uye reverse osmosis membranes zvinodyiwa mumidziyo yekurapa mvura. Saizi yepore ye reverse osmosis membrane inongova 1/100 yeiyo ye ultrafiltration membrane, saka reverse osmosis Midziyo yekurapa yeMvura inokwanisa kubvisa zvinorema simbi, mishonga yekuuraya zvipembenene, chloroform, uye zvimwe zvinosvibisa kemikari mumhando yemvura. Ultrafiltration mvura yekuchenesa haina simba. Iyo ultrafiltration mvura yekuchenesa inogona kubvisa zvinosvibisa uye mabhakitiriya, anogona kubviswa nereverse osmosis.
1. Musiyano wezvivakwa pakati peiyo ultrafiltration membrane uye reverse osmosis membrane:
Iyo reverse osmosis membrane ndeye artificial semi-permeable membrane ine humwe hunhu hwakagadzirwa nekutevedzera biological semi-permeable membrane. Kazhinji inogadzirwa ne polymer zvinhu. Iyo dhayamita ye membrane pores kazhinji iri pakati pe 0.5 uye 10 nm, uye iyo permeability ine hukama nemakemikari chimiro che membrane pachayo.
Ultrafiltration membrane imhando ye microporous filtration membrane ine saizi yepore yakafanana uye yakayerwa saizi yepore renji ye 0.001-0.02 microns. Kuisa dzvinyiriro yakafanira kune rimwe divi re membrane kunogona kuvheneka solute mamorekuru madiki pane saizi yepore kupatsanura zvimedu zvine huremu hwemamorekuru hunodarika 500 Daltons (atomic mass units) uye saizi yakakura kupfuura 10 nanometers. Iyo ultrafiltration membrane ndeimwe yekutanga polymer yekuparadzanisa membranes yakagadzirwa, uye ultrafiltration mudziyo wakagadzirwa muma1960s.
2. Zvakanakira uye kuipa kweultrafiltration membrane uye reverse osmosis membrane:
Zvakanakira zve ultrafiltration: kazhinji hapana pombi, hapana mashandisiro emagetsi, hapana matambudziko ekuchengetedza magetsi; majoini mashoma, dzvinyiriro yemvura shoma, mwero wakaderera wokukundikana, uye mukana wokubuda kwemvura; chimiro chiri nyore uye mutengo wakaderera;
Zvakaipa: mugumisiro wakashata wekubvisa makemikari anosvibisa mumvura; kukanganisa kwakashata pazviitiko zvakakosha zvekupa mvura; kusanaka zvishoma kwemvura; kusakwanisa kuderedza kuoma kwemvura, sekuoma kwemvura yemupombi, chigadziko chemvura inofashaira chinogona kusvibiswa.
Ultrafiltration membrane inogona kubvisa macromolecules, colloids, mapuroteni, zvimedu, nezvimwewo mune mhinduro, uye ine hunhu hwekudzikira kwakadzika, kugadzirwa kwemvura yakakura, uye kushanda kuri nyore. Nekuyedza maitiro ekurapa ehollow fiber ultrafiltration membrane mudziyo wekucheneswa kwakadzika kwemvura, zvinoratidzwa kuti iyo ultrafiltration membrane mvura yekuchenesa mudziyo inogona kunyatsobvisa kusvibiswa kwechipiri kwemvura mupombi network uye kuwedzera kunaka kwemvura.
Zvakanakira reverse osmosis mvura yekurapa midziyo: yakachengeteka mhando yemvura, inogona kunyatsobvisa marudzi ese ehutsvina hunokuvadza mumhando yemvura; mhedzisiro iri nani kune zviitiko zvakakosha zvekupa mvura; kunakirwa kwemvura kuri nani; inogona kunyatso kuderedza kuoma kwehutano hwemvura, uye chigadziko chemvura inopisa hachisi nyore kuyera;
Zvakaipa: pombi, kushandiswa kwesimba, nyaya dzekuchengetedza magetsi; majoini akawanda, dzvinyiriro yemvura yakakwira, mwero wakanyanya kukundikana, uye mukana wekudonha kwemvura; chimiro chakaoma, uye mutengo unodhura.
3. Kushandiswa kwemhando ye ultrafiltration membrane uye reverse osmosis membrane:
Kushandiswa kwemhando ye reverse osmosis membrane
Magetsi, petrochemical, simbi nesimbi, zvemagetsi, mushonga, chikafu nechinwiwa, manejimendi ekutonga nekuchengetedzwa kwezvakatipoteredza uye mimwe minda, mukubvisa salination yemvura yegungwa nemvura ine brackish, boiler feed mvura, maindasitiri emvura yakachena uye yemagetsi giredhi yekupedzisira-yakachena mvura kugadzirira, kunwa yakachena kugadzirwa kwemvura, tsvina yekuchenesa uye Iyo yakakosha nzira yekuparadzanisa inoita basa rakakosha.
Kushandiswa kwemhando ye ultrafiltration membrane
Mvura yakachena uye ultrapure mvura inoshandiswa se reverse osmosis pretreatment uye ultrapure mvura terminal kurapwa mukugadzirira maitiro; mvura yemumaindasitiri inoshandiswa kuparadzanisa mabhakitiriya, zvitubu zvinopisa, colloids, kusvibiswa kwakamiswa, uye macromolecular organics; mvura yekunwa, mineral water kuchenesa; kuvirisa, indasitiri yekugadzirira Enzyme uye indasitiri yemishonga yekuisa, kucheneswa, uye kujekeswa; juice yekuisa uye kupatsanurwa; soya bean, dairy, indasitiri yeshuga, waini, muto wetii, vhiniga, nezvimwewo kupatsanurwa, kutarisisa uye kujekesa; mvura yetsvina yemaindasitiri uye kucheneswa kwetsvina yemumba nekudzoreredza; Kudzorerwa kwependi ye electrophoretic.
