ʻO nā membrane nanofiltration ka hapa nui o nā membrane, me nā koina maikaʻi ʻole ma ka ʻili, hiki ke hoʻopaʻa i nā cations me ʻelua mau valences i loko o ka wai a mālama i nā ion monovalent (e like me nā ion sodium a me nā ion potassium).No laila, mālama nā membrane nanofiltration i kekahi mau minela i loko o ka wai.ʻAno mea.
Ma waena o nā mea hoʻohaumia metala kaumaha maʻamau, aia ka arsenic i loko o ka wai ma ke ʻano he trivalent arsenic ion a me pentavalent arsenic ions;Loaʻa ka chromium ma ke ʻano o nā ion trivalent a hexavalent ma ke ʻano.No laila hiki i ka nanofiltration membrane ke kānana i ka hapa nui o nā metala kaumaha.Hiki iā ia ke wehe i kahi ʻāpana o ka calcium a me ka magnesium, no laila he hopena i ka hoʻomaʻamaʻa ʻana i ka wai paʻakikī.
I ka manawa like, hiki i nā membrane nanofiltration ke hōʻemi i nā mea kūlohelohe i ka wai a me nā carcinogens e like me trihalomethanes i hana ʻia i ka wā chlorination a me ka disinfection o ka wai inu.
ʻO ka maʻi virus liʻiliʻi loa i ʻike ʻia he anawaena o 18nm-22nm (ʻikepili mai Wikipedia).Ke hoʻohālikelike ʻia me ka nui o ka pore o nā membranes nanofiltration o 1-2nm, ʻano nui nā bacteria a me nā maʻi virus, no laila hiki i nā membrane nanofiltration ke hana maikaʻi ʻO ka wehe ʻana i nā maʻi bacteria a me nā maʻi ʻaʻole paʻakikī ke noʻonoʻo.
ʻO ke kumu hana o ka membrane nanofiltration he hapa like ia me ka membrane reverse osmosis.ʻOi aku ka haʻahaʻa o ke kaomi ʻana ma mua o ka membrane reverse osmosis, no laila e hoʻohua mai i ka wai ʻino ma mua o ka membrane reverse osmosis.
ʻO ia kekahi o nā mea hana membrane RO mua loa ma Kina, HIDTMkūlana i nā hōʻailona maikaʻi loa ma waena o ka ʻoihana membrane RO Kina.Hiki i nā membrane nanofiltration ke kānana i nā ion metala ma luna o ʻelua valences i ka wai (ʻo ka mea maʻamau, he liʻiliʻi loa ka ʻike o nā ion monovalent i loko o ka wai, a ʻo lākou nā minerala āpau e pono ai ke kino kanaka), ʻoiai ʻoi aku ka haʻahaʻa o ke kaomi hana o nā membrane nanofiltration ma mua o ʻOi aku ka kiʻekiʻe ma mua o nā membrane osmosis hoʻohuli a hiki ke hoʻopau loa i nā ion calcium a me ka magnesium i maʻalahi i ka unahi ʻana i ka wai.Ua lawa ka hoʻohana ʻana i nā membrane nanofiltration e hoʻokō i nā pono o ka wai inu.
- He huahana nanofiltration membrane koho nui ia i hoʻomohala kūikawā no ka hoʻokuʻu ʻole a me ka hoʻohana waiwai.
- He kiʻekiʻe ke kiʻekiʻe o ka hōʻole ʻana o ka ion multivalent, haʻahaʻa ka haʻahaʻa o ka hōʻole ʻana o nā ion monovalent, a pololei ka ʻoki paona molecular.
- He kūpono hoʻi ia no nā lāʻau liʻiliʻi analytical Isolation and Purification.
- Hoʻohana ʻia ka hoʻolālā grid kūikawā i ke kahawai kahe inlet i ʻoi aku ka maikaʻi o ka huahana i ka pale ʻana i ka pollution a me ka hoʻomaʻemaʻe maʻalahi.
Nānā:
1. Hoʻopili ʻia nā ʻāpana hana ma hope o ka holo paʻa ʻana o ka ʻōnaehana no 30 mau minuke.2. ʻO ka hoʻokaʻawale ʻana o ka hana wai he ± 15%.
2.1.5 ʻIke nui
Pono ka hoʻomaka kūpono no ka hana paʻa o ka ʻōnaehana nanofiltration.Ma mua o ka hoʻopau ʻia ʻana o ka ʻōnaehana nanofiltration a hoʻomaka hou ʻia ma lalo o kahi lōʻihi.
Pono e nānā a hoʻoponopono ʻia ka mokuʻāina o ka wā pani, nā mea hana like ʻole, nā mika, a me ka maikaʻi o ka wai e hōʻoia i ka hoʻokō ʻana o nā kūlana āpau i nā hoʻonohonoho a hoʻonohonoho i nā waiwai.
ma hope o ke kauoha ʻana.E ʻoluʻolu e nānā i ka manual huahana no nā ʻanuʻu hana kikoʻī a me ka mālama ʻana.
I mea e pale ai i ka membrane mai ka ʻoki ʻia ʻana e nā ʻāpana paʻakikī, pono e hoʻohana ʻia kahi kānana palekana 5μm me ka ʻole o ka holoi ʻana i hope i ka wai.
puka komo.Ke kiʻekiʻe loa ka ʻike silika, hiki ke hoʻohana ʻia kahi kānana palekana 1μm.Pono ke kaomi ma ka ʻaoʻao hana wai o ka module membrane
ʻaʻole i ʻoi aku ka kiʻekiʻe ma mua o ke kaomi ʻana ma ka ʻaoʻao wai hānai i kēlā me kēia manawa, a ʻo ka paʻa hope paʻa pono e emi iho ma mua o 5 psi.
Hoʻohana nui ʻia nā Membranes HID™ NF i:
1. Hoʻopili ʻia ka lāʻau antibiotic ma nā mahana haʻahaʻa e wehe i ka lehu.
2. ʻO ka hoʻoheheʻe ʻana o ka wai, ka hoʻopaʻa ʻana, ka paʻakai paʻakai, ka ua wai.
3. Ka hoʻopaʻa ʻana o ka wai kō lahilahi, hoʻomaʻemaʻe i nā oligosaccharides.
4. ʻO ka unuhi ʻana a me ka noʻonoʻo ʻana o nā mea hana biologically.
5. ʻO ka mālama ʻana i ka wai ʻino a me ka hana hou ʻana.
6. Hoʻomaʻemaʻe a hoʻomaʻemaʻe i nā protein like ʻole, nā amino acids, nā huaora, ka waiū, ka waiʻona, ka soy sauce, condiments, etc.
