Nanofiltration (NF) le Reverse Osmosis (RO) Membranes: Molao-motheo, Likopo, le Litebello tsa Maraka.
Melao-motheo ea Nanofiltration le Reverse Osmosis
Li-membrane tsa Nanofiltration (NF) le Reverse Osmosis (RO) ke karolo ea lelapa la filtration ea theknoloji ea tlhoekiso ea metsi, e sebelisang khatello ea ho arola litšila metsing. Mefuta ena ka bobeli ea li-membrane ha e khonehe, e lumella limolek'hule tsa metsi hore li fete ha li ntse li thibela li-ion tse itseng, limolek'hule le likaroloana.
Nanofiltration (NF) e sebetsa tlas'a khatello e itekanetseng (5-15 bar) 'me e na le boholo ba pore sebakeng sa nanometer (hoo e ka bang 1-2 nanometers). Li-membrane tsa NF li khetha li-ion tse kholoanyane tse fapaneng le tse nang le mefuta e mengata, limolek'hule tse phelang, le likokoana-hloko tse itseng tse nyenyane, empa li lumella li-ion tsa monovalent (joaloka sodium le chloride) hore li fete. Khetho ena e etsa hore NF e be e loketseng lits'ebetso tseo ho tsona ho lakatsoang ho tlosoa ha liminerale ka mokhoa o itseng.
Reverse Osmosis (RO) e sebetsa tlas'a khatello e phahameng (15-70 bar) 'me e na le boholo bo nyane ba pore, hangata bo ka tlase ho nanometer e le 1. Sena se lumella RO ho tlosa mefuta e mengata ea litšila, ho kenyelletsa le letsoai le qhibilihisitsoeng, metsoako ea organic le livaerase, tse hlahisang metsi a hloekileng haholo. Li-membrane tsa RO ha e le hantle li hana ho feta 99% ea matsoai a qhibilihisitsoeng, a etsa hore a tšoanelehe bakeng sa lits'ebetso tse hlokang metsi a boleng bo holimo.
Likopo tsa Nanofiltration le Reverse Osmosis Membranes
Ka bobeli li-membrane tsa NF le RO li sebelisoa haholo liindastering tse 'maloa, haholo kalafong ea metsi, lijo le lino, meriana le ts'ebetso ea lik'hemik'hale.
Phekolo ea Metsi: RO le NF li sebelisoa haholo limela tsa desalination ho fana ka metsi a nooang ho tsoa metsing a leoatle kapa mehloling ea brackish. Li-membrane tsa RO li fana ka tlhoekiso e phahameng bakeng sa lits'ebetso tsa metsi a nooang le a ultrapure, athe NF hangata e ratoa bakeng sa ho nolofatsa lits'ebetso le ho tlosa litšila tse itseng tse kang nitrate, chefo e bolaeang likokoanyana le litšepe tse boima.
Lijo le Seno: Li-membrane tsa NF li thusa ts'ebetsong ea lebese, moo li sebelisetsoang ho tsepamisa maikutlo le ho tlosa lebese le whey ka mokhoa o itseng. Ka lehlakoreng le leng, li-membrane tsa RO li sebelisoa ho kopanya lero la litholoana le tlhoekiso ea tsoekere, li fana ka filtrate ea boleng bo holimo le ho ntlafatsa bophelo ba sethala sa lihlahisoa.
Pharmaceuticals and Biotechnology: Lefapheng la meriana, NF le RO li bohlokoa haholo ho hlahiseng metsi a sa hloekang le a sa hloekang bakeng sa tlhahiso ea lithethefatsi le mekhoa ea theknoloji ea baeloji. NF e ka arola limolek'hule tse rarahaneng ha RO e fana ka metsi a hloekisitsoeng a bohlokoa bakeng sa lithethefatsi tse nang le ente.
Tšebeliso ea Lik'hemik'hale: Li-membrane tsa NF li sebelisoa bakeng sa ho tlosoa ha ion ka mokhoa o khethehileng ha ho etsoa lik'hemik'hale, moo metsoako e khethehileng e lokelang ho aroloa kapa ho kenngoa. RO e hiriloe ho tlosa litšila tse qhibilihisitsoeng, ho netefatsa bohloeki le botsitso ba sehlahisoa.
Litebello tsa 'Maraka
Tlhokahalo ea li-membrane tsa NF le RO e ntse e phahama haholo, e susumetsoa ke tlhoko e ntseng e hola ea metsi a bolokehileng, a hloekileng le melao e thata e mabapi le phallo ea metsi a litšila. Lintlha tsa bohlokoa tse tlatsetsang kholong ea 'maraka li kenyelletsa:
Khaello ea Metsi a Lefatše le Phaello ea Metsi: Ha khaello ea metsi a hloekileng e ntse e eketseha lefatšeng ka bophara, ho ntša letsoai ka li-membrane tsa RO e fetohile tharollo ea bohlokoa. NF e boetse e na le karolo ea bohlokoa ho poekisoe le ho sebelisoa ha metsi hape, haholo maemong a temo le a indasteri.
Keketseho ea Ts'ebeliso ea Liindasteri: Liindasteri tsa lijo le lino, tsa meriana le tsa lik'hemik'hale li ntse li eketseha lefatšeng ka bophara, li hlohlelletsa tlhokahalo ea metsi a boleng bo holimo le tlhoekiso e khethehileng. NF le RO's application versatility e ipiletsa ho mefuta e mengata ea liindasteri tse hlokang tharollo e lokiselitsoeng ea ho sefa.
