Yenziwa kanjani i-RO Membrane?

I-Reverse Osmosis (RO) ubuchwepheshe obujwayelekile bokuhlanza amanzi. Ngokufaka ukucindezela okukhulu emanzini angenayo kanye nolwelwesi lwe-osmosis oluhlehlisayo, amanzi ageleza esuka kolunye uhlangothi lolwelwesi (uhlangothi lokuphakelayo lwamanzi) aye kolunye uhlangothi (uhlangothi lokukhiqiza amanzi).

Iningi lezinye izakhi kulowo onamandla, njengosawoti oncibilikisiwe, izinhlayiya, amagciwane kanye ne-pyrogen, zizohlala ohlangothini lwamanzi okuphakelayo olwelwesi futhi ekugcineni zizokhishwa njengamanzi angcolile.

Esimweni semvelo, amanzi ezinhlangothini zombili zefilimu ekwazi ukuvunyelwa kancane ageleza esuka esisombululo esincibilikisiwe aye esixazululweni esigxilile, kodwa uma sisebenzisa ingcindezi enkulu ngokwanele ohlangothini lwesisombululo esigxilile, amanzi azogeleza abheke emuva kwesixazululo esigxilisiwe → isixazululo se-dilute, futhi isiqondiso sokugeleza kwe-solvent siphambene nesiqondiso sokungena kwasekuqaleni, ngakho-ke kubizwa ngokuthi i-reverse o.

Isistimu ye-osmosis ehlane ihlukaniswe yaba ulwelwesi lwendlu lwangaphandle kanye ne-internal roll reverse osmosis membrane.

Njengoba kubonisiwe emfanekisweni, ulwelwesi oluvamile lwe-osmosis oluhlanekezelwe luhlukaniswe kakhulu lwaba yizinhlanu ezinhlanu: zombili iziphetho zekepisi, ishubhu eliphakathi nendawo, uphawu lwe-O-ring, ulwelwesi lwe-osmosis olungemuva, kanye negridi yokukhiqiza amanzi/ukukhiqiza amanzi.

Ama-osmosis amaningi ahlanekezelanayo agqigqana negridi yokukhiqiza/yokudonsa amanzi, ngayinye ngayinye, imiphetho yawo ivalwa ngeglu, bese wonke alimala eshubhu eliphakathi nendawo. Phakathi kwazo, ungqimba lwegridi: luhlinzeka ngomzila wokugeleza kwamanzi aluhlaza kanye nokuphuma kwamanzi okukhiqiza, ukuvimbela ukunamathela kwe-RO membrane, ulwelwesi olwehlayo lwe-osmosis: ukukhipha usawoti kanye nokuhlunga kwamanzi anethonya.
