I-Nanofiltration (NF) yindlela yokwahlula inwebu inwebu eneempawu ezininzi ezine-reverse osmosis (RO). Ngokungafaniyo ne-RO, egatya phantse zonke i-solutes ezinyibilikisiweyo, i-NF iyagatya i-ion ezininzi ezifana ne-calcium ngelixa igatya i-ion ze-monovalent njenge-chloride.
Kwii-membraane ze-HID sinika umgca we-nanofiltration (NF) i-membrane eziphuhliswe ukunika i-flux efanelekileyo kunye nokugatywa kwaye inokuguqulwa ukuhlangabezana neemfuno ezithile zeenkqubo ezahlukeneyo zokusebenza. Iimembrane zethu ze-nanofiltration, ezifumaneka kwi-spiral-wound kunye ne-flat sheet membrane topology, zinokwala iityuwa ezininzi kunye neemolekyuli ezinkulu ngelixa ngokukhetha ukwala ukutshintsha amanqanaba eetyuwa ze-monovalent.
Indlela yokwahlula i-nanofiltration ibonakaliswe yi-organic, ifilimu encinci ye-membrane edibeneyo kunye nobukhulu be-pore ukusuka kwi-0.1 ukuya kwi-10nm. Iimbumba ze-NF, ngokungafaniyo ne-reverse osmosis (RO) iimbrane, zinokusebenza kuxinzelelo oluphantsi kwaye zivumele ukwaliwa okukhethiweyo okusekelwe kubukhulu kunye nentlawulo.
Iimbumba zethu ze-nanofiltration, ezinobungakanani be-pore ukusuka kwi-0.1 ukuya kwi-10nm, zivumela amanzi kunye neetyuwa ezithile ukuba zihambe ngelixa ugcina i-ion ezininzi, ii-molekyuli ezinobunzima obuphantsi, i-carbohydrates, iiprotheni kunye nezinye izinto eziphilayo. I-HID ye-NFS, i-NFX, i-NFW, kunye ne-NFG yeemveliso ze-nanofiltration inwebu ziye zaboniswa ukuba zinikeze ukuxhathisa okugqwesileyo, ukukhetha okuphezulu, kunye nokuqina komzimba okufunekayo ukuze kusetyenziswe kuluhlu olubanzi lweenkqubo zokwahlukana kwezoshishino emva kweminyaka yophando kunye nophuhliso.
I-MgSO4 kunye nokulahlwa kwe-lactose kulungile kwi-NFS, i-NFX, kunye ne-NFW, kanti i-NFG ngokuyinxenye isusa i-monosaccharides kwi-oligosaccharides. I-Nanofiltration membranes inokunciphisa kakhulu ubunzima, i-nitrate, i-sulfates, i-tannins, i-turbidity, umbala, i-TDS, kunye namanqanaba etyuwa ephakathi kwimisinga yamanzi yokutya.
I-Nanofiltration membranes yinto entsha efunyenweyo ebonelela ngokukhetha okungcono kwe-ion kune-reverse osmosis membranes, ekhaba zonke iintlobo ze-ion kumjelo wokutya. Olu phawu olwahlukileyo luvumela ukuguquguquka okukhulu ekuphuhliseni inkqubo yokwahlula, enokuthi ibe nefuthe elibonakalayo ekusebenzeni kunye noqoqosho, ngakumbi kwizicelo zoshishino. Nantsi imizekelo embalwa yendlela itekhnoloji ye-NF inwebu esetyenziswa ngayo:
- I-Lactose kunye ne-whey demineralization ekusebenzeni kobisi
- I-Lactose kunye ne-whey concentration
- Ukususwa kwezinto eziphilayo zendalo emanzini kunye nonyango lwamanzi amdaka
- Ukunciphisa ubunzima ekuhlanjululeni kwamanzi
- Ukususwa kwesulfate emanzini olwandle kunye neenkqubo zeekhemikhali
- Ukususwa kwetyuwa kwimisinga yenkqubo kumashishini ahlukeneyo
