Nā Pūnaehana EDI Electrodeionization

kiʻi 1 Nā noi EDI

Hoʻopau nā ʻōnaehana EDI Electrodeionization i nā ion mai nā kahawai wai. ʻO ka mea maʻamau e hui pū me ʻOsmosis hoʻohuli (RO) a me nā mea hoʻomaʻemaʻe ʻē aʻe. No laila, hana mau kā mākou mau modula kiʻekiʻe i ka wai maʻemaʻe loa a hiki i 18.2MΩ/cm. No laila, hiki ke holo mau ʻia ʻo EDI a i ʻole intermittently. ʻO ka hopena, he hopena ʻōmaʻomaʻo ka electrodeionization no ka wai deionizing.

He aha ka Pūnaehana EDI?

ʻO ka mea mua, ʻo ka electrodeionization (EDI) kahi mea uila Lapaau wai ʻenehana. No laila, hoʻohana ia i ka uila, nā membrane hoʻololi ion a me ka resin e wehe i nā ʻano ionized mai ka wai.

He aha nā ʻōnaehana Electrodeionization EDI e wehe ai mai ka wai?

Hoʻopau nā ʻōnaehana EDI Electrodeionization i nā ion a me nā ʻano mea ʻē aʻe i hoʻopaʻa ʻia mai ka wai, no ka laʻana, nā paʻakai a me nā waikawa organik.

Pehea e hana ai ka Electrodeionization EDI Systems?

Aia nā ʻōnaehana Electrodeionozation EDI i kahi hoʻonohonoho o nā keʻena. No laila, hoʻopiha mākou i kēia keʻena me nā resins exchange ion a hoʻokaʻawale ʻia e nā membranes-exchange. No laila, komo ka wai i loko o ka module, kahi i hoʻohana ʻia ai ke kahua uila ma nā kihi ʻākau i ka kahe e hoʻoneʻe i nā ion e neʻe i loko o nā resins a ma waena o nā membrane. ʻAʻole paʻa mau kēia mau ion haumia i ka media. Akā, ʻo ka ʻōnaehana e hōʻiliʻili iā lākou i loko o nā kahawai concentrate kahi e hoʻokahe ai a hana hou paha. Hiki iā ʻoe ke hoʻohana pololei i ka wai huahana deionized a i ʻole e mālama hou ʻia no ka hoʻomaʻemaʻe wai hoʻonui.

kiʻi 3 Ka papa kuhikuhi o EDI

Ke hana nei ka module EDI, ma ke ʻano he moena hoʻololi ion e hoʻomau mau ʻia me ka uila. Ke neʻe nā ion i loko o nā resins a ma waena o ka cation a i ʻole nā anion koho membranes. No laila, hoʻololi electrodeionization EDI Systems no nā H+ a me OH- ion. No laila, neʻe aku nā ion i hoʻopaʻa ʻia i nā resins hoʻololi ion i kahi keʻena ʻokoʻa. Ma lalo o ka mana o ke kahua uila i hoʻohana ʻia i waho; e hana pū ana kēia i nā ion H+ a me OH- pono e mālama i nā resins i ko lākou kūlana hou. ʻO nā ion i loko o ke keʻena kaʻawale, ʻōnaehana holoi iā lākou a pau.

I kēia manawa, ʻokoʻa nā palena o nā ʻōnaehana electrodeionozation EDI mai ka hoʻololi ion maʻamau a i ʻole Pūnaehana Reverse Osmosis. Eia kekahi, ua kaupalena ʻia ka hoʻomaʻemaʻe wai ionic huahana ma ka huina o nā ion i lawe ʻia e nā resins. ʻO ka hopena, ka palena kiʻekiʻe o ka hōʻea ʻana o nā ion i kaupalena i ka EDI. ʻO ke kiʻekiʻe loa ka haʻawe ionic e hoʻonui i ka module e like me ia. No laila, hoʻohana pinepine mākou i ka EDI ma hope o ka reverse osmosis a, inā paʻakikī loa ka wai, me ka degassing e wehe i ka carbon dioxide.

Nā noi maʻamau o UA ___ IA

Ka wai no ka hale mana

Ma kahi o ka hoʻohana ʻana i kahi moena huikau maʻamau, hiki i ka membrane degasser i hui pū ʻia me EDI ke hana i ka wai demineralized kiʻekiʻe me ka ʻole o ka hoʻohana ʻana i nā kemika. Hāʻawi kēia i ka wai hānai boiler corrosion-free me ka haʻahaʻa conductivity a me ka ʻike silica.

ʻO ka wai kaʻina ultrapure

Hāʻawi ʻo EDI ma hope o ka reverse osmosis i ka wai kaʻina ultrapure me ka conductivity haʻahaʻa. Hōʻike ke kiʻi iā EDI no ka wai ultrapure ma kahi hui microelectronic. Hoʻonohonoho ʻia ka EDI me nā modula lāʻau lapaʻau kūikawā no kahi hoʻolālā maʻemaʻe.

ʻO ka wai no ka lāʻau lapaʻau

Pono ka hana wai hoʻomaʻemaʻe i loko o nā ʻoihana lāʻau lapaʻau i kahi ʻōnaehana mālama wai ma kahi hoʻolālā maʻemaʻe. Hoʻonohonoho ʻia ka EDI e hālāwai me nā mana o kēia manawa o ʻEulopa a me United States Pharmacopoeia (USP, Ph. Eur.).
