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 inogona 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 nekemikari chimiro che membrane pachayo.
Ultrafiltration membrane imhando yemicroporous filtration membrane ine saizi yepore yakafanana uye yakayerwa saizi yepore renji ye0.001-0.02 microns.Kuisa kudzvanya kwakakodzera kune rimwe divi re membrane kunogona kuvharidzira mamorekuru madiki pane saizi yepore kupatsanura zvidimbu zvine huremu hwemamorekuru hunodarika mazana mashanu eDaltons (atomic mass units) uye saizi yakakura kupfuura gumi nanomita.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 yakaderera, 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 chiri kufashaira chinogona kusvibiswa.
Ultrafiltration membrane inogona kubvisa macromolecules, colloids, mapuroteni, zvimedu, nezvimwewo mune mhinduro, uye ine maitiro ekuderera kwepasi, kugadzirwa kwemvura yakakura, uye nyore kushanda.Nekuyedza maitiro ekurapa kwegomba fiber ultrafiltration membrane mudziyo wekucheneswa kwakadzika kwemvura, zvinoratidzwa kuti iyo ultrafiltration membrane mvura yekuchenesa mudziyo inogona kunyatso kubvisa kusvibiswa kwechipiri kwemvura mupombi network uye kuwedzera kunaka kwemvura.
Zvakanakira reverse osmosis mvura yekurapa michina: yakachengeteka mhando yemvura, inogona kunyatso bvisa 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 inofashaira haisi 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 manejimendi nekuchengetedzwa kwezvakatipoteredza uye mimwe minda, mukubvisa salination yemvura yegungwa nemvura ine brackish, boiler feed mvura, maindasitiri mvura yakachena uye yemagetsi giredhi yekupedzisira-yakachena mvura kugadzirira, kunwa kugadzirwa kwemvura yakachena, kurapwa kwemvura yakasviba uye Iyo yakakosha yekuparadzanisa maitiro 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 bhinzi, dairy, indasitiri yeshuga, waini, muto wetii, vhiniga, nezvimwewo kupatsanurwa, kuisa pfungwa uye kujekesa;mvura yetsvina yemaindasitiri uye kucheneswa kwetsvina yemumba nekudzoreredza;Kudzorerwa kwependi ye electrophoretic.
