Nanofiltration (NF) ni membrane ya fluid-itandukanya tekinike ifite ibintu byinshi hamwe na osmose ihinduka (RO). Bitandukanye na RO, yanga ibisubizo hafi ya byose byashonze, NF yanze ion nyinshi nka calcium mugihe yanze ion monovalent nka chloride.
Kuri HID membraanes dutanga umurongo wa nanofiltration (NF) membrane yatunganijwe kugirango itange flux nziza kandi yange kandi irashobora guhindurwa kugirango ihuze ibyifuzo byihariye bya porogaramu zitandukanye. Ibibyimba byacu bya nanofiltration, biboneka muri spiral-igikomere hamwe na flat top membrane topologiya, birashobora kwanga imyunyu myinshi hamwe na molekile nini mugihe duhitamo guhitamo urwego rwumunyu wa monovalent.
Tekinike yo gutandukanya nanofiltration irangwa na organic, thin-firime compite membrane ifite ubunini bwa pore kuva kuri 0.1 kugeza 10nm. NF membrane, itandukanye na osmose (RO) ihindagurika, irashobora gukora kumuvuduko wo hasi kandi ikemerera guhitamo kwanga guhitamo bitewe nubunini nubunini.
Ibibyimba byacu bya nanofiltration, bifite ubunini bwa pore buri hagati ya 0.1 na 10nm, butuma amazi numunyu runaka bitembera mugihe hagumye ion nyinshi, molekile zifite uburemere buke, karubone, proteyine, nibindi bintu kama. HID's NFS, NFX, NFW, na NFG nanofiltration yibicuruzwa byagaragaye ko bitanga imbaraga nziza zo guhangana nabi, guhitamo cyane, hamwe nigihe kirekire cyumubiri gisabwa kugirango ukoreshwe muburyo butandukanye bwo gutandukanya inganda nyuma yubushakashatsi niterambere.
Kwanga MgSO4 na lactose nibyiza muri NFS, NFX, na NFW, mugihe NFG ikuraho monosaccharide muri oligosaccharide. Nanofiltration membrane irashobora kandi kugabanya cyane ubukana, nitrate, sulfate, tannine, ububobere, ibara, TDS, hamwe numunyu woroheje mumigezi y'ibiryo.
Nanofiltration membrane ni ibintu bishya byavumbuwe bitanga uburyo bwiza bwo guhitamo ion kuruta guhinduranya osmose membrane, yanga amoko yose ya ion mumigezi yo kugaburira. Iyi miterere itandukanye ituma habaho guhinduka mugutezimbere inzira yo gutandukana, bishobora kugira ingaruka zikomeye kumikorere nubukungu, cyane cyane mubikorwa byinganda. Dore ingero nke zukuntu tekinoroji ya NF membrane ikoreshwa:
- Lactose na whey demineralisation mugutunganya amata
- Kwibanda kwa Lactose
- Kurandura ibintu kama kama mumazi no gutunganya amazi mabi
- Kugabanya ubukana mu kweza amazi
- Kuvana sulfate mumazi yinyanja nuburyo bwimiti
- Gutesha agaciro inzira zinyuranye mubikorwa bitandukanye
