Hoʻohana ʻia nā ʻano membrane like ʻole i ka ʻoihana mālama wai, a ʻo nā mea maʻamau ka ultrafiltration membranes a me ka reverse osmosis membranes.ʻO nā membrane ultrafiltration ʻelua a me nā membrane reverse osmosis nā mea hoʻohana i nā lako mālama wai.ʻO ka nui o ka pore o ka reverse osmosis membrane he 1/100 wale nō ia o ka membrane ultrafiltration, no laila hiki i nā mea hoʻomaʻemaʻe wai ke hoʻopau pono i nā metala kaumaha, nā pesticides, chloroform, a me nā mea haumia ʻē aʻe i ka maikaʻi o ka wai.ʻAʻole mana nā mea hoʻomaʻemaʻe wai Ultrafiltration.Hiki i ka mea hoʻomaʻemaʻe wai ultrafiltration ke hoʻoneʻe i nā pollutant particulate a me nā bacteria, hiki ke hoʻoneʻe ʻia e ka reverse osmosis.
1. ʻO ka ʻokoʻa o nā waiwai ma waena o ka membrane ultrafiltration a me ka membrane reverse osmosis:
ʻO ka reverse osmosis membrane he membrane semi-permeable artificial me kekahi mau hiʻohiʻona i hana ʻia e ka hoʻohālikelike ʻana i kahi membrane semi-permeable biological.Hana ʻia me nā mea polymer.ʻO ke anawaena o nā pores membrane ma waena o 0.5 a me 10 nm, a pili ka permeability i ke ʻano kemika o ka membrane ponoʻī.
ʻO ka membrane Ultrafiltration kahi ʻano o ka microporous filtration membrane me ka nui o ka nui o ka pore kikoʻī a me ka nui o ka pore i helu ʻia o 0.001-0.02 microns.ʻO ka hoʻohana ʻana i ke kaomi kūpono ma kekahi ʻaoʻao o ka membrane hiki ke pale i nā molekala solute liʻiliʻi ma mua o ka nui o ka pore e hoʻokaʻawale i nā ʻāpana me ke kaumaha molekala i ʻoi aku ma mua o 500 Daltons (nā ʻāpana atomika) a me ka nui o ka nui ma mua o 10 nanometer.ʻO ka membrane ultrafiltration kekahi o nā membrane hoʻokaʻawale polymer mua i kūkulu ʻia, a ua hana ʻia ka ʻenehana ultrafiltration i nā makahiki 1960.
2. ʻO nā pono a me nā pōʻino o ka membrane ultrafiltration a me ka membrane reverse osmosis:
ʻO nā mea maikaʻi o ka ultrafiltration: maʻamau ʻaʻohe pahū, ʻaʻohe mana mana, ʻaʻohe pilikia palekana uila;ka liʻiliʻi o nā hui, haʻahaʻa ke kaomi wai, haʻahaʻa haʻahaʻa haʻahaʻa, a me ka hiki ke kahe wai;hale maʻalahi a me ke kumu kūʻai haʻahaʻa;
Nā pōʻino: nā hopena maikaʻi ʻole o ka wehe ʻana i nā mea haumia kemika i ka wai;hopena maikaʻi ʻole i nā hanana kūikawā o ka hoʻolako wai;ka ʻono iki o ka wai;hiki ʻole ke hōʻemi i ka paʻakikī o ka wai, e like me ka paʻakikī kiʻekiʻe o ka wai paipu, hiki ke ʻino ka ipu wai paila.
Hiki i ka Ultrafiltration membrane ke wehe i nā macromolecules, colloids, proteins, particles, etc.Ma ka hoʻāʻo ʻana i ka hopena lapaʻau o ka mea hollow fiber ultrafiltration membrane no ka hoʻomaʻemaʻe hohonu o ka wai, ua hōʻike ʻia e hiki i ka ultrafiltration membrane wai hoʻomaʻemaʻe pono ke hoʻopau pono i ka lua o ka haumia o ka wai i loko o ka pūnaewele paipu a hoʻomaikaʻi hou i ka maikaʻi o ka wai.
ʻO nā mea maikaʻi o ka reverse osmosis wai lāʻau lapaʻau: maikaʻi ka wai maikaʻi, hiki ke hoʻopau pono i nā ʻano mea ʻino ʻino i ka maikaʻi o ka wai;ka hopena maikaʻi no nā hanana kūikawā o ka hoʻolako wai;ʻoi aku ka maikaʻi o ka wai;hiki ke hoʻemi pono i ka paʻakikī o ka maikaʻi o ka wai, a ʻaʻole maʻalahi ka palaki ʻana o ka ipu wai paila;
Nā pōʻino: nā paila, ka hoʻohana mana, nā pilikia palekana uila;ka nui o na ami, ka nui o ka wai, ka nui o ka hemahema, a me ka leakage wai;hale paʻakikī, a me ke kumu kūʻai pipiʻi.
3. Ka hoʻohana ʻana o ka membrane ultrafiltration a me ka membrane reverse osmosis:
Ka hoʻohana ʻana o ka membrane reverse osmosis
ʻO ka uila, ka petrochemical, ka hao a me ke kila, nā mea uila, ka lāʻau lapaʻau, ka meaʻai a me ka mea inu, ka hoʻokele aupuni a me ka mālama ʻana i ke kaiapuni a me nā māla ʻē aʻe, i ka desalination o ka wai kai a me ka wai paʻakai, ka wai hānai boiler, ka wai maʻemaʻe ʻoihana a me ka hoʻomākaukau ʻana i ka wai maʻemaʻe uila. inu i ka hana wai maʻemaʻe, hoʻomaʻemaʻe wai ʻino a He hana koʻikoʻi ka hana hoʻokaʻawale kūikawā.
Ka laulā noi o ka membrane ultrafiltration
Hoʻohana ʻia ka wai maʻemaʻe a me ka wai ultrapure e like me ka reverse osmosis pretreatment a me ka ultrapure water terminal treatment i ka papa hana hoʻomākaukau;hoʻohana ʻia ka wai ʻoihana e hoʻokaʻawale i nā huakini, nā kumu wela, nā colloids, nā mea haumia i hoʻopaneʻe ʻia, a me nā mea kanu macromolecular;wai inu, hoʻomaʻemaʻe wai mineral;fermentation, ʻoihana hoʻomākaukau Enzyme a me ka ʻoihana lāʻau lapaʻau, hoʻomaʻemaʻe, a wehewehe;ka nui o ka wai a me ka hoʻokaʻawale ʻana;ka soya, ka waiu, ka ʻoihana kō, ka waina, ka wai kī, ka vīneka, a me nā mea ʻē aʻe.ka hoʻomaʻemaʻe a me ka hoʻihoʻi hou ʻana i ka wai ʻino ʻoihana a me ka hoʻomaʻemaʻe hale;Hoʻihoʻi hou i ka pena electrophoretic.
Mākaukau e aʻo hou aku?E kelepona mai iā mākou i kēia lā no kahi ʻōlelo manuahi!
