Hoʻoemi Maʻamau Ro Membrane Module - Industrial NF Membrane HNF-4040HF – HID Membrane

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, loaʻa 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 hapa o ka calcium a me ka magnesium, no laila he hopena koʻikoʻi 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 hoʻohana pono ʻO ka wehe ʻana i nā maʻi 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 liʻiliʻi ka wai ʻino ma mua o ka membrane reverse osmosis.

ʻO ia kekahi o nā mea hana membrane RO mua loa ma Kina, HID^TM kūlana 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 loko o ka wai (ʻo ka mea maʻamau, he liʻiliʻi loa ka ʻike o nā ion monovalent i ka wai, a ʻo lākou nā minerala āpau e pono ai ke kino o ke kanaka), ʻoiai ʻoi aku ka haʻahaʻa o ke kaomi hana o nā membranes nanofiltration ma mua o ka reverse osmosis membranes, a ʻoi aku ka kiʻekiʻe o 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 ka helu hōʻole ʻana o nā ion multivalent, haʻahaʻa ka helu hōʻole ʻana o nā ion monovalent, a pololei ka ʻoki ʻana i ke kaumaha mole.
- He mea kūpono 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 lako 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 i ʻole nā ​​​​waiwai hoʻonohonoho.
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 pono me ka holoi ʻole ʻana 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 iʻoi aku ka kiʻekiʻe ma mua o ke kaomi ma kaʻaoʻao wai hānai i kēlā me kēia manawa, aʻo ka paʻi hope paʻa pono e emi iho ma mua o 5 psi.
