Ukuthuthukiswa kanye nokusetshenziswa kombala wemvelo sekuyindaba ekhathazayo jikelele kubasebenzi besayensi nezobuchwepheshe ezimbonini ezihlukahlukene.Abantu bazama ukuthola izingulube zemvelo ezinsizeni ezihlukahlukene zezilwane nezitshalo futhi bahlole imisebenzi yabo yokuphila ukuze banciphise futhi baxazulule izinkinga ezihlukahlukene ezibangelwa izingulube zokwenziwa.Inqubo yokukhipha izingulube zemvelo ibuye ibuyekezwe ngokushesha, futhi manje ubuchwepheshe bokuhlukaniswa kwe-membrane buye baba enye yezindlela eziyinhloko zokukhishwa kwe-pigment yemvelo.
Ukuhlukaniswa kwe-Membrane kuhlanganisa izinqubo ezine eziyinhloko zolwelwesi lwe-cross-flow: i-microfiltration MF, i-ultrafiltration UF, i-nanofiltration NF, kanye ne-osmosis RO ehlehlayo.Ukuhlukaniswa nokugcinwa kokusebenza kolwelwesi oluhlukahlukene kuhlukaniswa ngosayizi wembotshana kanye nokusikwa kwesisindo se-molecular of the membrane.Ubuchwepheshe bokuhlunga i-Membrane busetshenziswe kakhulu kwezokwelapha, odayi, ezimbonini zokucubungula ukudla kanye nejusi emazweni asentshonalanga athuthukile.Ukusetshenziswa kobuchwepheshe be-membrane filtration ekukhiqizeni izingulube zemvelo kungathuthukisa isivuno sokukhiqizwa kwezingulube zemvelo, kususe odayi besibili kanye nokungcola okuncane kwamangqamuzana, futhi kunciphise izindleko zokukhiqiza.Ngokungangabazeki, ubuchwepheshe be-membrane budlale indima ebalulekile ekuhlanganiseni isimo salezi zinkampani embonini ye-pigment yemvelo, futhi busetshenziswe ngempumelelo ebhizinisini elithile lasekhaya lokukhiqiza umbala wemvelo.
Enqubweni yokukhiqiza i-pigment, ikakhulukazi uketshezi lokuphakelayo olunokugxila okuqinile okuphansi, uma kuqhathaniswa nendlela yokuhlunga egcwele, idivayisi yokuhlukanisa ulwelwesi kusetshenziswa indlela yokuhlunga okugeleza kwe-cross-flow kunciphisa kakhulu ukuvinjelwa kwendawo yolwelwesi ngenxa yokugeleza kwe-cross-flow impahla kanye noketshezi, okungathuthukisa izinga lokuhlunga.isilinganiso.Ngaphezu kwalokho, idivayisi ye-membrane ingenziwa inzalo ngesikhathi esifanayo, futhi asikho isidingo sokusetha enye inqubo yokuvala inzalo nokuhlunga, ukuze kufezwe inhloso yokwenza inqubo ibe lula nokunciphisa izindleko.
1. Ubuchwepheshe be-Microfiltration bungahluza izakhi ezingancibiliki ezikhiqizweni ze-pigment yemvelo kanye nokungcola okunesisindo samangqamuzana esihlobene esikhulu kunezinkulungwane ezingamakhulu amaningana, njengesitashi, i-cellulose, i-vegetable gum, i-macromolecular tannins, amaprotheni ama-macromolecular nokunye ukungcola.
2. I-Ultrafiltration isetshenziselwa ukucaciswa kwama-pigment akhiqizwa ukuvutshelwa, esikhundleni sendlela yokucacisa yendabuko, ingakwazi ukuvimbela ngokuphumelelayo ukumiswa kwama-macromolecular namaprotheni, futhi ivumele ukukhishwa kwe-pigment ecacile ukuthi ingene nge-membrane futhi ingene ohlangothini lwe-permeate.
3. I-Nanofiltration isetshenziselwa ukugxilisa/ukukhipha amanzi e-pigments ekamelweni lokushisa, ngokuvamile lihlanganiswe noma esikhundleni sama-evaporator.Ngesikhathi sokuhlunga, amanzi nokunye ukungcola kwe-molecule encane (okufana ne-citrinin ku-monascus) kudlula kulwelwesi kuyilapho izingxenye ze-pigment zigcinwa futhi zigxilile.
Eminyakeni yamuva nje, ukuthuthukiswa nokusetshenziswa kombala wemvelo kuye kwathuthuka ngokushesha.Kodwa-ke, ucwaningo nokuthuthukiswa kwezingulube zemvelo zisabhekene nezinkinga eziningi: izinga lokukhishwa kwezingulube zemvelo liphansi, futhi izindleko ziphezulu;ukuzinza kwe-pigment kumpofu, futhi kuzwela ezimweni zangaphandle ezifana nokukhanya nokushisa;kunezinhlobo eziningi, futhi ucwaningo nentuthuko kuhlakazekile.Ngokuthuthuka nokuthuthukiswa kobuchwepheshe bokuhlukaniswa kwe-membrane, kukholakala ukuthi izodlala indima ebaluleke kakhulu ekukhishweni kwezingulube zemvelo.Esikhathini esizayo, inhlanganisela yobuchwepheshe bokuhlukaniswa kwe-membrane ye-liquid kanye nobuchwepheshe obusha obuhlukahlukene kuzokwandisa ukukhishwa kwemibala yemvelo futhi kuthuthukise ikhwalithi yomkhiqizo, kunciphise izindleko zokukhiqiza.
