Nanofiltration (NF) dabara ce ta raba ruwa-ruwa wacce ke da kaddarorin da yawa tare da juyawa osmosis (RO). Ba kamar RO ba, wanda ya ƙi kusan duk narkar da solutes, NF ya ƙi ions masu yawa kamar calcium yayin da yake ƙin ions masu monovalent kamar chloride.
A HID membraanes muna samar da layin nanofiltration (NF) membranes waɗanda aka haɓaka don ba da mafi kyawun juzu'i da ƙin yarda kuma ana iya canzawa don saduwa da takamaiman buƙatun aikace-aikacen tsari daban-daban. Mu nanofiltration membranes, waxanda suke samuwa a karkace-rauni da lebur membrane topologies, na iya ƙin multivalent salts da kuma manyan kwayoyin yayin zabar ƙin canza matakan monovalent salts.
Dabarar rabuwar nanofiltration tana da siffa ta kwayoyin halitta, membranes na fim na bakin ciki tare da girman pore daga 0.1 zuwa 10nm. Membran NF, sabanin membranes na baya osmosis (RO), na iya aiki a ƙananan matsi kuma suna ba da izinin ƙin yarda da zaɓaɓɓu dangane da girman duka da caji.
Mu nanofiltration membranes, tare da pore size jere daga 0.1 zuwa 10nm, ba da damar ruwa da wasu salts su gudãna ta yayin da ajiye multivalent ions, ƙananan kwayoyin nauyi kwayoyin, carbohydrates, sunadarai, da sauran kwayoyin abubuwa. HID's NFS, NFX, NFW, da NFG nanofiltration samfuran membrane an nuna su don ba da kyakkyawan juriya mai ƙazanta, babban zaɓi, da ƙarfin jiki da ake buƙata don amfani a cikin manyan hanyoyin rabuwar masana'antu bayan shekaru na bincike da haɓakawa.
MgSO4 da ƙin yarda da lactose suna da kyau a cikin NFS, NFX, da NFW, yayin da NFG wani ɓangare ya kawar da monosaccharides daga oligosaccharides. Nanofiltration membranes na iya mahimmanci rage taurin, nitrates, sulfates, tannins, turbidity, launi, TDS, da matakan gishiri mai laushi a cikin rafukan ruwa.
Nanofiltration membranes wani sabon bincike ne wanda ke ba da mafi kyawun zaɓin ion fiye da koma bayan osmosis membranes, waɗanda ke ƙin duk nau'in ion a cikin rafi.
