Momwe Reverse Osmosis Imagwirira Ntchito: Kuyeretsa Madzi Kudzera Kusefera Kwapamwamba

1. Osmosis vs. Reverse Osmosis

- Natural Osmosis: Mwachilengedwe, madzi amayenda mumkanda womwe umatha kutha pang'onopang'ono kuchokera kudera lotsika kwambiri la solute kupita kumadzi osungunuka kwambiri kuti agwirizane mbali zonse ziwiri (mkuyu 1a). Izi zimafuna mphamvu zopanda mphamvu.

(Lingaliro lowoneka: Zigawo ziwiri zolekanitsidwa ndi nembanemba; madzi amapita ku mbali ya mchere.)

- Reverse Osmosis: RO imatembenuza mayendedwe awa. Pogwiritsa ntchito kupanikizika kwakukulu kuposa mphamvu ya osmotic yachilengedwe, madzi amakakamizika kuchoka kumtunda wapamwamba (woipitsidwa) kupita kumbali yotsika (yoyera), kusiya zonyansa (mkuyu 1b).

(Lingaliro lowoneka: Kukakamiza komwe kumayikidwa kumbali ya mchere; mamolekyu amadzi amapyola mu nembanemba pomwe mchere / zowononga zimatsekeka.)

2. Mtima wa RO: Semipermeable Membrane

Nembanemba ya RO ndi polima wandiweyani, wamitundu yambiri (nthawi zambiri polyamide) yokhala ndi ma pores ang'onoang'ono (~ 0.0001 ma microns). Ma pores awa ndi ang'ono kuti atseke:

- Mchere wosungunuka (mwachitsanzo, Na⁺, Cl⁻)

- Zitsulo zolemera (monga lead, arsenic)

- Mabakiteriya, ma virus, ndi ma organic molecule

Kapangidwe ka Membrane:

1. Gulu Lothandizira: Limapereka mphamvu zamakina.
2. Porous Layer: Imalola madzi kudutsa.
3. Gulu Logwira Ntchito: Pepala lopyapyala kwambiri la polyamide lokhala ndi ma nano-kakulidwe pores posankha kusefa.

3. Mmene Zoipitsira Amachotsera

- Kupatula Kukula: Mamolekyu akuluakulu (monga mchere, zinthu zamoyo) sangathe kudutsa timabowo tating'ono.

- Charge Repulsion: Pamwamba pa nembanemba pamakhala magetsi, kubweza ma ion omwe ali ndi ndalama zofananira.

- Kukaniza Kukaniza: Zowononga zimatsekeredwa ndikutayidwa ngati madzi oyipa.

4. Mapulogalamu a RO

- Kuchotsa mchere: Kusintha madzi am'nyanja kukhala madzi abwino.

- Njira Zamadzi Akumwa: Kuchotsa zowononga pampopi zapakhomo.

- Mafakitale: Mankhwala, kupanga chakudya/zakumwa, ndi kuthira madzi oipa.

5. Zovuta

- Kugwiritsa Ntchito Mphamvu: Zofunikira zothamanga kwambiri zimawonjezera kugwiritsa ntchito mphamvu.

- Kuwonongeka kwa Membrane: Tinthu tating'onoting'ono timatha kutseka pores, zomwe zimafunikira kukonzedwa pafupipafupi.

Mapeto

Reverse osmosis imagwiritsa ntchito sayansi yapamwamba komanso physics kuti ipereke madzi oyera. Pomvetsetsa mfundo za osmotic ndi kapangidwe ka membrane, titha kukulitsa machitidwe a RO kukhala tsogolo lokhazikika.
