Khutlisetsa Membrane ea Osmosis ho Litlhophiso tsa Indasteri: Melao-motheo, Likopo, le Tlhokomelo.
Li-membrane tsa Reverse Osmosis (RO) li emela theknoloji ea karohano e tsamaisoang ke khatello e matla e amoheloang haholo liindastering tse hlokang metsi a hloekileng haholo. Ho sebelisa li-membrane tse nang le semi-permeable tse boholo ba pore tse nyane joalo ka 0.0001 mm, RO e tlosa matsoai a qhibilihisitsoeng, litšepe tse boima, likokoana-hloko, le litšila tse phelang ka mekhoa e 'meli ea bohlokoa:
Kenyelletso ea Boholo ba Limolek'hule: Likarolo tse kholo ho feta limolek'hule tsa metsi (ho kenyeletsoa libaktheria le livaerase) li koetsoe 'meleng.
Electrostatic Repulsion: Libaka tse nang le membrane tse sa qosoang hampe li leleka anion tse kang chloride (Cl).⁻) le sulfate (SO₄²⁻).
Lipompo tsa khatello e phahameng (1.5-10.5 MPa) hlola khatello ea tlhaho ea osmotic ho arola metsi a hloekisitsoeng (a phunyeletsa) le litšila tse teteaneng (brine). Li-membrane tsa sejoale-joale tsa RO tsa indasteri li sebelisa lisebelisoa tsa polyamide thin-film composite (TFC), ho fihlela ho lahla letsoai ho fihla ho 99.6% ha li ntse li boloka botsitso ba mochini.
Lisebelisoa tsa indasteri -- Theknoloji ea RO e sebetsana le mathata a rarahaneng a metsi ho pholletsa le makala:
1. Ho ntša letsoai:
E fetolela metsi a leoatle kapa metsi a letsoai hore e be metsi a nooang kapa a sebetsoang bakeng sa 'masepala, lifeme tsa motlakase le libaka tsa tlhoekiso.
2. Tlhahiso ea Metsi a Hloekileng:
Bohlokoa bakeng sa tlhahiso ea semiconductor le lisebelisoa tsa meriana, moo tšilafalo ea ionic e sitisang mekhoa.
3. Tšebeliso ea metsi a litšila:
Tlhoekiso ea likhoerekhoere ea masepala e khutlisa metsi bakeng sa nosetso (>99% ea ho tlosoa ha likokoana-hloko).
Phekolo ea metsi a litšila ea indasteri e tlosa litšepe tse boima (mohlala, > 99% ea ho hlaphoheloa ha nickel/cadmium) le ho nyenyefatsa oli (ho fihla ho 99.96% ea phokotso ea COD e sebelisa li-demulsifiers).
Taolo ea Mokelikeli oa Nyutlelie: Liphetoho tsa membrane tsa hydrophilic kapa tse sa nke lehlakore li tšoara metsi a litšila a nang le mahlaseli a kotsi ha a ntse a hanela ho silafatsoa.
Mathata a Tlhokomelo le Litharollo
Ho silafala ha lisele-e bakoang ke kholo ea likokoana-hloko, ho eketseha ha liminerale, kapa likaroloana tsa colloidal-e fokotsa ts'ebetso ea phallo le ho eketsa tšebeliso ea matla. Maano a bohlokoa a kenyelletsa:
1. Thibelo:
Chlorine dosing (
Li-antiscalants le taolo ea pH (6-8) li thibela liminerale tse kang CaCO₃.
Ho phekola pele ka ho sefa lehlabathe, ultrafiltration, kapa coagulation ho tlosa likaroloana.
2. Mekhoa ea ho hloekisa:
Biofouling: Hloekisa ka tharollo ea 0.1% ea formaldehyde.
Ho lekanya liminerale: Kenya 2% citric acid (pH 4-8) ka litekanyetso tse phahameng tsa phallo.
Katoloso ea Bophelo: Sebelisa li-pre-filters tse sirelletsang (PP/carbon), boloka turbidity ea phepelo (SDI -0.98 MPa). Li-membrane tsa RO tse hlokometsoeng hantle hangata li sebetsa 3-Lilemo tse 5 pele ho phetoho.
Litlhahiso le Pono ea Bokamoso - Tsoelo-pele ea theknoloji ea membrane e tsoela pele ho ntlafatsa katleho:
1. Thin-Film Nanocomposites (TFN): Li-membrane tse kentsoeng ka Nanoparticle li ntlafatsa phallo ea metsi ka 200% ha li ntse li ntlafatsa thepa ea antifouling.
2. IoT Integration: Li-sensors li lekola conductivity le likhatello tse fapaneng ho bolela esale pele ho foiling le ho iketsetsa lipotoloho tsa ho hloekisa.
3. Keketseho ea 'Maraka: Ka lebaka la khaello ea metsi lefatšeng ka bophara, lekala la "membrane la RO" ho hakanngoa hore le tla hola ka litheko tse tsitsitseng tsa linomoro tse peli ho fihlela ka 2033.
Qetello
Li-membrane tsa RO li bohlokoa haholo ho nolofalletsang tšebeliso e tsitsitseng ea metsi a indasteri le tlhoekiso. Ts'ebetso ea bona e ipapisitse le melao-motheo e sebelisoang ka thata ea mahlale, ts'ebetsong e ikhethileng ea lekala, le tlhokomelo e matla. Ha boqapi bo ntse bo tsoela pele ho sebetsa hantle le ho beha leihlo ka bohlale, theknoloji ea RO e tla bapala karolo ea bohlokoahali ho bolokeng mehloli ea metsi bakeng sa indasteri le sechaba.
"Liindastering tse nang le khatello ea metsi, RO e fetola litšila hore e be mohloli-molek'hule e le 'ngoe ka nako."
