Kamoo Reverse Osmosis e Sebetsang Kateng: Ho Hloekisa Metsi ka ho Filtration e tsoetseng pele

1. Osmosis vs. Reverse Osmosis

- Natural Osmosis: Ka tlhaho, metsi a tsamaea ka lera la semipermeable ho tloha sebakeng se tlaase sa solute concentration ho ea ho solute e phahameng ho leka-lekanya mahlakore ka bobeli (Setšoantšo sa 1a). Ts'ebetso ena e sa sebetseng ha e hloke matla.

(Tlhahiso e bonoang: Likarolo tse peli tse arohaneng ka lera; metsi a phalla ho ea ka lehlakoreng le nang le letsoai.)

- Reverse Osmosis: RO e khutlisa phallo ena. Ka ho sebelisa khatello e kholo ho feta khatello ea tlhaho ea osmotic, metsi a qobelloa ho tloha ka lehlakoreng le phahameng (le silafetseng) ho ea lehlakoreng le tlaase (le hloekileng), le siea litšila ka morao (setšoantšo sa 1b).

(Tlhahiso e bonoang: Khatello e sebelisoa lehlakoreng la letsoai; limolek'hule tsa metsi li phunyeletsa lera ha matsoai / litšila li thibiloe.)

2. Pelo ea RO: The Semipermeable Membrane

Lera la RO ke polymer e teteaneng, e nang le mefuta e mengata (hangata polyamide) e nang le li-microscopic pores (~ 0.0001 microns). Li-pores tsena li nyane hoo li ka thibelang:

- Matsoai a qhibilihisitsoeng (mohlala, Na⁺, Cl⁻)

- Litšepe tse boima (mohlala, loto, arsenic)

- Libaktheria, livaerase le limolek'hule tsa tlhaho

Sebopeho sa Membrane:

1. Lera la Tšehetso: E fana ka matla a mochine.
2. Porous Layer: E lumella metsi ho feta.
3. Active Layer: Letlapa la polyamide le tšesaane haholo le nang le masoba a boholo ba nano bakeng sa tlhoekiso e khethehileng.

3. Kamoo Litšilafatso li Nkoang Kateng

- Kenyelletso ea Boholo: Limolek'hule tse kholoanyane (mohlala, matsoai, lintho tse phelang) ha li khone ho feta masobeng a manyane.

- Charge Repulsion: Lera la membrane le na le motlakase, le leleka li-ion tse nang le litefiso tse tšoanang.

- Khahlano le Phatlalatso: Litšila li qabeletsoe ebe li tšeloa joalo ka metsi a litšila.

4. Lisebelisoa tsa RO

- Desalination: Ho fetola metsi a leoatle ho ba metsi a hloekileng.

- Lits'ebetso tsa metsi a nooang: Ho tlosa litšila tse tsoang lipompong tsa ka tlung.

- Liindasteri: Meriana, tlhahiso ea lijo / lino, le ho hloekisa metsi a litšila.

5. Mathata

- Tšebeliso ea Matla: Litlhoko tse phahameng tsa khatello li eketsa tšebeliso ea matla.

- Membrane Fouling: Likaroloana li ka koala li-pores, tse hlokang tlhokomelo ea kamehla.

Qetello

Reverse osmosis e sebelisa mahlale a tsoetseng pele le fisiks ho fana ka metsi a hloekileng. Ka ho utloisisa melao-motheo ea osmotic le moralo oa membrane, re ka ntlafatsa mekhoa ea RO bakeng sa bokamoso bo tsitsitseng.
