Lisebelisoa tse fapaneng tsa membrane li sebelisoa indastering ea ho hloekisa metsi, 'me tse tloaelehileng haholo ke li-membrane tsa ultrafiltration le li-membrane tsa reverse osmosis.Ka bobeli li-membrane tsa ultrafiltration le li-membrane tsa reverse osmosis li ka sebelisoa lisebelisoa tsa ho hloekisa metsi.Boholo ba pore ea lera la reverse osmosis ke 1/100 feela ea lera la ultrafiltration, kahoo reverse osmosis Lisebelisoa tsa ho hloekisa metsi li ka tlosa litšepe tse boima, chefo e bolaeang likokoanyana, chloroform le litšila tse ling tsa lik'hemik'hale boleng ba metsi.Lisebelisoa tse hloekisang metsi ka Ultrafiltration ha li na matla.Sehloekisi sa metsi sa ultrafiltration se ka tlosa litšila tse itseng le libaktheria, tse ka tlosoang ke reverse osmosis.
1. Phapang ea thepa pakeng tsa lera la ultrafiltration le reverse osmosis membrane:
Lera la reverse osmosis ke lera la maiketsetso le nang le libopeho tse itseng tse entsoeng ka ho etsisa lesela la biological semi-permeable.Hangata e entsoe ka thepa ea polymer.Bophara ba li-membrane pores hangata bo pakeng tsa 0.5 le 10 nm, 'me ho phunyeha ho amana le sebopeho sa lik'hemik'hale tsa lera ka boeona.
Ultrafiltration membrane ke mofuta oa microporous filtration membrane e nang le boholo bo lekanang ba pore le boholo bo lekantsoeng ka boholo ba li-microns tse 0.001-0.02.Ho sebelisa khatello e nepahetseng ka lehlakoreng le le leng la lera ho ka hlahisa limolek'hule tsa solute tse nyane ho feta boholo ba pore ho arola likaroloana tse nang le boima ba molek'hule bo fetang 500 Daltons (li-atomic mass unit) le boholo ba karoloana e kholo ho feta 10 nanometers.Lera la ultrafiltration ke e 'ngoe ea li-membrane tsa pele tsa karohano ea polima e entsoeng,' me sesebelisoa sa ultrafiltration se ile sa etsoa indasteri ka bo-1960.
2. Melemo le mefokolo ea lera la ultrafiltration le reverse osmosis membrane:
Melemo ea ultrafiltration: ka kakaretso ha ho na lipompo, ha ho tšebeliso ea matla, ha ho mathata a tšireletso ea motlakase;manonyeletso a fokolang, khatello e tlase ea metsi, sekhahla se batlang se le tlase sa ho hloleha, le monyetla oa ho lutla ha metsi;sebopeho se bonolo le theko e tlaase;
Go tlhoka mesola: phello e mpe ea ho tlosa litšila tsa lik'hemik'hale ka metsing;phello e mpe liketsahalong tse khethehileng tsa phepelo ea metsi;tatso e fokolang ea metsi;ha e khone ho fokotsa boima ba metsi, joalo ka ho thatafala haholo ha metsi a pompo, sejana sa metsi a belang se ka senyeha.
Ultrafiltration membrane e ka tlosa macromolecules, colloids, protheine, likaroloana, joalo-joalo ka tharollo, 'me e na le litšobotsi tsa khatello e tlaase, tlhahiso e kholo ea metsi, le ts'ebetso e bonolo.Ka ho hlahloba phello ea phekolo ea sekoti se nang le sekoti sa fiber ultrafiltration membrane bakeng sa tlhoekiso e tebileng ea metsi, ho pakoa hore mochine oa ho hloekisa metsi oa ultrafiltration o ka felisa tšilafalo ea bobeli ea metsi ka har'a marang-rang a phala le ho ntlafatsa boleng ba metsi.
Melemo ea lisebelisoa tsa ho hloekisa metsi a reverse osmosis: boleng ba metsi a sireletsehileng, bo ka tlosa ka katleho mefuta eohle ea litšila tse kotsi boleng ba metsi;phello e ntle bakeng sa liketsahalo tse khethehileng tsa phepelo ea metsi;tatso e ntle ea metsi;e ka fokotsa ka katleho boima ba boleng ba metsi, 'me setshelo sa metsi a belang ha se bonolo ho lekanya;
Mefokolo: lipompo, tšebeliso ea matla, litaba tsa polokeho ea motlakase;manonyeletso a mangata, khatello e phahameng ea metsi, tekanyo e batlang e phahame ea ho hlōleha, le monyetla oa ho lutla ha metsi;sebopeho se rarahaneng, le theko e batlang e turu.
3. Lenane la ts'ebeliso ea lera la ultrafiltration le lera la osmosis le khutlisetsang morao:
Lethathamo la ts'ebeliso ea lera la reverse osmosis
