Phapang lipakeng tsa lisebelisoa tsa ultrafiltration le lisebelisoa tsa reverse osmosis

Phapang e kholo lipakeng tsa lera la ultrafiltration le reverse osmosis ke phapang ea boholo ba pore. Boholo ba pore ea sekepe sa reverse osmosis membrane ke peresente e le 'ngoe ea lera la ultrafiltration,' me ho nepahala ha filtration ea reverse osmosis membrane e phahame ho feta ea ultrafiltration membrane. Ultrafiltration membrane ha e bapisoa le reverse osmosis membrane, reverse osmosis membrane aperture e nyane haholo ho feta ultrafiltration membrane, reverse osmosis membrane aperture ke 0.0001 micron, ultrafiltration membrane aperture ke 0.001 micron. Boholo ba pore ea lera la reverse osmosis ke peresente e le 'ngoe ea lera la ultrafiltration, kahoo metsi a hloekisitsoeng ke lera la reverse osmosis a hloekile ho feta a lera la ultrafiltration.

Ultrafiltration membrane ke mokhoa oa ho arola lera moo lera le nang le sebopeho sa porous asymmetric. Tshebetso ea ho hloekisa ke mokhoa oa ho arohana oa tharollo o thehiloeng ho molao-motheo oa sieving oa mochine oa phapang pakeng tsa mahlakoreng a mabeli a lera, khatello ea ho sebetsa hangata ke 0.01 ho 0.03Mpa, 'me boholo bo botle ba pore ea lera la ultrafiltration ke hoo e ka bang 0.001 ho 0.01 microns. Boima ba molek'hule ke 1,000-500,000 daltons, kahoo ts'ebetso ea ho arohana ha lera la ultrafiltration e kile ea nkoa e le mokhoa oa karohano ea 'mele feela.

Reverse osmosis membrane ke lera la maiketsetso le nang le semi-permeable le lisebelisoa tse ikhethileng tse entsoeng ka ho etsisa lesela la bioloji le nang le semi-permeable. RO ke khutsufatso ea Senyesemane ea reverse osmosis membrane, Sechaena ke moelelo oa reverse osmosis. Kakaretso ea metsi ho tloha tlase ho ea holimo. Ha metsi a hatelloa, metsi a tla phalla ho tloha holimo ho ea tlaase. Sena se bitsoa molao-motheo oa reverse osmosis. Sebaka sa lera la reverse osmosis ke karolo ea limilione tse hlano (0,0001 micron) ea moriri oa motho. Libaktheria le livaerase li kholoanyane ka makhetlo a 5,000, li lumella limolek'hule tsa metsi feela le li-ion tse ling tse molemo hore li fete, ha litšila tse ling le litšepe tse boima li ntšoa liphaepheng tsa metsi a litšila.

Sekhahla sa lera la reverse osmosis ke 1/100 ea lesoba la lera la ultrafiltration, 'me ho nepahala ha filtration ea RO reverse osmosis membrane e fihla ho 0.0001 micron. Leha ho le joalo, ho nepahala ha filthara ea lera la ultrafiltration ke 0.001 microns. Ka hona, li-membrane tsa reverse osmosis li ka tlosa litšepe tse boima, chefo e bolaeang likokoanyana, chloroform le litšila tse ling tsa lik'hemik'hale metsing, empa li-membrane tsa ultrafiltration ha li khone. Lera la ultrafiltration le tlosa litšila tse itseng le libaktheria, 'me reverse osmosis e tlosa matla' ohle.
