Loaʻa nā kiʻi i hoʻoiho ʻia mai ka Massachusetts Institute of Technology Press Office pūnaewele i nā hui waiwai ʻole, ka media, a me ka lehulehu ma lalo o ka Creative Commons Attribution NonCommercial No Derivatives License.ʻAʻole hiki iā ʻoe ke hoʻololi i nā kiʻi i hāʻawi ʻia ke ʻole i ʻoki ʻia i ka nui kūpono.Pono e hoʻohana ʻia ka hōʻaiʻē i ka wā e pāʻani ana i nā kiʻi;inā ʻaʻole i helu ʻia ma lalo, e hoʻopili i ke kiʻi i "MIT".
Ua hoʻomohala nā mea noiʻi ma Massachusetts Institute of Technology i kahi mea hoʻoheheʻe lawe lima ma lalo o 10 kg e hoʻoneʻe ai i nā ʻāpana a me ka paʻakai e hana i ka wai inu.
Hoʻohana ʻia ka mana liʻiliʻi ma mua o ka loina kelepona a hiki ke hoʻohana ʻia e ka panel solar liʻiliʻi liʻiliʻi hiki ke kūʻai ʻia ma ka pūnaewele no kahi $50.Hoʻopuka koke ia i ka wai inu ma mua o nā kūlana o ka World Health Organization.Hoʻopili ʻia ka ʻenehana i loko o kahi mea hoʻohana e hana ai ma kapaʻi pihi.
ʻAʻole like me nā mea hana wai lawe lima ʻē aʻe e koi ana i ka wai e hele i loko o kahi kānana, hoʻohana kēia mea uila i ka uila e wehe i nā ʻāpana mai ka wai inu.ʻAʻole koi ʻia ke kānana pani, e hōʻemi nui i ka pono no ka mālama lōʻihi.
Hiki i kēia ke ʻae i ka ʻāpana e hoʻoili ʻia i nā wahi mamao a me nā kumu waiwai nui, e like me nā kaiāulu ma nā mokupuni liʻiliʻi a i ʻole ma luna o nā moku ukana o waho.Hiki ke hoʻohana ʻia e kōkua i ka poʻe mahuka e holo ana i nā pōʻino kūlohelohe a i ʻole nā koa i komo i nā hana kaua lōʻihi.
"ʻO kēia ka hopena o kahi huakaʻi 10 makahiki noʻu a me kaʻu hui.I loko o nā makahiki, ua hana mākou i ka physics ma hope o nā kaʻina desalination like ʻole, akā e hoʻokomo i kēia mau holomua āpau i loko o kahi pahu, kūkulu i kahi ʻōnaehana a hana i loko o ke kai.He mea maikaʻi loa ia a he ʻike hoʻomaikaʻi iaʻu, "wahi a ka mea kākau kiʻekiʻe ʻo Jongyoon Han, he polopeka o ka ʻenekini uila, ʻepekema kamepiula, a me ka bioengineering a he lālā o ka Electronics Research Laboratory (RLE).
Ua hui pū ʻia ʻo Khan e ka mea kākau mua ʻo Jungyo Yoon, RLE Fellow, Hyukjin J. Kwon, hoa postdoctoral mua, Sungku Kang, hoa postdoctoral ma Northeastern University, a me US Army Combat Capabilities Development Command (DEVCOM) Eric Braque.Ua paʻi ʻia ke aʻo ʻana ma ka pūnaewele ma ka puke pai Environmental Science & Technology.
Ua wehewehe ʻo Yoon e koi maʻamau nā mea kanu desalination portable pāʻoihana i nā pamu kaomi kiʻekiʻe e hoʻokuʻu i ka wai ma o nā kānana, he paʻakikī ke hoʻoemi ʻia me ka ʻole o ka hoʻololi ʻana i ka pono o ka ikehu.
Akā, hoʻokumu ʻia kā lākou hāmeʻa i kahi ʻenehana i kapa ʻia ʻo ka ion-concentration polarization (ICP), kahi i hoʻokumu ʻia e ka hui o Khan ma mua o 10 mau makahiki i hala.Ma kahi o ka kānana wai, hoʻopili ke kaʻina hana ICP i kahi kahua uila i kahi membrane aia ma luna a ma lalo o ke ala wai.Ke hele aku nā ʻāpana maikaʻi a maikaʻi ʻole paha, me nā molekala paʻakai, nā maʻi bacteria a me nā maʻi maʻi, e hoʻihoʻi ʻia lākou mai ia mea.Hoʻouna ʻia nā ʻāpana i hoʻopiʻi ʻia i loko o kahi kahawai ʻelua o ka wai, a laila e hoʻokuʻu ʻia.
Hoʻopau kēia kaʻina hana i nā mea paʻa i hoʻoheheʻe ʻia a hoʻokuʻu ʻia, e ʻae ana i ka wai maʻemaʻe e hele ma nā kahawai.No ka mea e koi wale ana i ka pauma haʻahaʻa haʻahaʻa, hoʻohana ka ICP i ka ikehu ma mua o nā ʻenehana ʻē aʻe.
ʻAʻole naʻe e wehe mau ʻo ICP i nā paʻakai a pau e lana ana ma waena o ke kahawai.No laila ua hoʻokō nā mea noiʻi i kahi kaʻina hana ʻelua i kapa ʻia ʻo electrodialysis e wehe i nā ion paʻakai i koe.
Ua hoʻohana ʻo Yun lāua ʻo Kang i ke aʻo ʻana i ka mīkini e ʻike i ka hui kūpono o ICP a me nā modula electrodialysis.ʻO ka hoʻonohonoho maikaʻi loa he ʻelua kaʻina ICP kahi e hele ai ka wai i ʻeono modules i ka pae mua, a laila ma ʻekolu modules i ka lua o ka pae, a ukali ʻia e kahi kaʻina electrodialysis.Hoʻemi kēia i ka hoʻohana ʻana i ka ikehu i ka wā e hoʻomaʻemaʻe iā ia iho.
"ʻOiai heʻoiaʻiʻo e hiki ke hopuʻia kekahi mau mea i hoʻopiʻiʻia e ka membrane hoʻololi ion, inā paʻa lākou, hiki iā mākou ke wehe maʻalahi i nā mea i hoʻoukaʻia ma ka hoʻololi waleʻana i ka polarity o ke kahua uila," weheweheʻo Yun.
Ua hōʻemi lākou a hoʻopaʻa i ka ICP a me nā modula electrodialysis e hoʻomaikaʻi i ko lākou ikehu pono a ʻae iā lākou e komo i nā ʻāpana lawe.Ua hoʻomohala nā mea noiʻi i kahi mea hana no ka poʻe ʻaʻole loea e hoʻomaka i ke kaʻina hana o ka desalination a me ka hoʻomaʻemaʻe me hoʻokahi wale nōpihi.Ke hāʻule ka paʻakai a me ka helu ʻāpana ma lalo o kekahi mau paepae, haʻi ka mea hoʻohana i ka mākaukau o ka wai e inu.
Ua hana pū ka poʻe noiʻi i kahi polokalamu kelepona e hoʻokele uila i ka hāmeʻa a hōʻike i ka ʻikepili manawa maoli e pili ana i ka hoʻohana ʻana i ka ikehu a me ka wai paʻakai.
Ma hope o nā hoʻokolohua hoʻokolohua me ka wai o nā pae like ʻole o ka paʻakai a me ka turbidity (turbidity), ua hoʻāʻo ʻia ka mea hana ma ke kula ma ke kahakai ʻo Carson ma Boston.
Hoʻonoho ʻo Yoon lāua ʻo Kwon i ka pahu ma ke kapa a hoʻokuʻu i ka mea hānai i loko o ka wai.Ma hope o ka hapalua hola, hoʻopiha ka mea hana i ke kīʻaha plastik me ka wai inu maʻemaʻe.
"He mea hauʻoli loa a kāhāhā no ka holomua ʻana ma ka hoʻomaka mua ʻana.Akā ke manaʻo nei au ʻo ke kumu nui o kā mākou kūleʻa ʻo ka hōʻiliʻili ʻana o kēia mau hoʻomaikaʻi liʻiliʻi a mākou i hana ai ma ke ala, "wahi a Khan.
ʻOi aku ka wai ma mua o nā kūlana maikaʻi o ka World Health Organization, a ʻo ka hoʻokomo ʻana e hōʻemi i ka nui o nā mea paʻa i hoʻokuʻu ʻia ma kahi o 10 mau manawa.Hoʻopuka kā lākou prototype i ka wai inu ma ka wikiwiki o 0.3 lita i kēlā me kēia hola a hoʻopau wale i 20 watt-hola no ka lita.
Wahi a Khan, ʻo kekahi o nā paʻakikī nui loa i ka hoʻomohala ʻana i kahi ʻōnaehana portable ʻo ia ka hana ʻana i kahi hāmeʻa intuitive hiki i kekahi ke hoʻohana.
Manaʻo ʻo Yoon e hoʻolaha i ka ʻenehana ma o ka hoʻomaka ʻana e hoʻolālā ʻo ia e hoʻolauna i mea e ʻoi aku ka maikaʻi o ka mea hoʻohana a hoʻomaikaʻi i kona ikaika a me ka hana.
I loko o ka lab, makemake ʻo Khan e hoʻohana i nā haʻawina āna i aʻo ai i nā makahiki he ʻumi i hala aku nei i nā pilikia maikaʻi o ka wai ma mua o ka desalination, e like me ka ʻike wikiwiki ʻana o nā mea haumia i ka wai inu.
"He papahana hoihoi loa ia a ke haʻaheo nei au i ka holomua a mākou i hana ai i kēia manawa, akā nui nā hana e hana ʻia," wahi āna.
No ka laʻana, ʻoiai ʻo "ka hoʻomohala ʻana i nā ʻōnaehana portable me ka hoʻohana ʻana i nā kaʻina electromembrane he ala kumu a hoihoi hoʻi no ka desalination wai liʻiliʻi ʻē aʻe," nā hopena o ka pollution, ʻoi aku ka nui o ka wai, hiki ke hoʻonui nui i nā pono mālama a me nā kumukūʻai ikehu. , wahi a Nidal Hilal, Prof. engineer a me ka luna o ka Abu Dhabi Water Research Center ma ke Kulanui o New York, ʻaʻole i komo i ka noiʻi.
"ʻO kahi palena ʻē aʻe ka hoʻohana ʻana i nā mea waiwai," i hoʻohui ʻo ia."He mea hoihoi ia ke ʻike i nā ʻōnaehana like me ka hoʻohana ʻana i nā mea kūʻai ʻole."
Ua hoʻolako kālā ʻia ke aʻo ʻana e ka DEVCOM Soldier Center, ka Abdul Latif Jameel Water and Food Systems Laboratory (J-WAFS), ka Northeastern University Postdoctoral Fellowship Program ma Experimental Artificial Intelligence, a me ka Ru Institute of Artificial Intelligence.
Ua hoʻomohala ka poʻe noiʻi ma MIT's Electronics Research Laboratory i kahi mea hana wai lawe hiki ke hoʻololi i ke kai i wai inu palekana, e like me ka Fortune's Ian Mount.Ua kākau ʻo Mount i ka mea ʻepekema noiʻi ʻo Jongyun Khan a me ka haumāna puka kula ʻo Bruce Crawford i hoʻokumu iā Nona Technologies e kūʻai i ka huahana.
ʻO nā mea noiʻi ma ke Keʻena ʻenehana ʻo Massachusetts "ua hoʻomohala i kahi mea hoʻoheheʻe manuahi manuahi me nā ʻāpana he nui o nā evaporators e hoʻihoʻi i ka wela mai ka condensation o ka mahu wai, e hoʻonui ana i kona pono holoʻokoʻa," hōʻike ʻo Neil Nell Lewis o CNN."Ke manaʻo nei ka poʻe noiʻi e hiki ke hoʻonohonoho ʻia ma ke ʻano he papa lana ma ke kai, hoʻoheheʻe ʻia i ka wai hou i uka, a i ʻole hiki ke hoʻolālā ʻia e lawelawe i hoʻokahi hale e hoʻohana ana ia mea i loko o kahi pahu wai kai," i kākau ai ʻo Lewis.
Ua hoʻomohala ka poʻe noiʻi MIT i kahi mea hoʻoheheʻe lawe lima hiki ke hoʻololi i ka wai paʻakai i wai inu ma kapaʻi pihi, hōʻike ʻo Elisaveta M. Brandon o ka Hui wikiwiki.Hiki i ka mea "mea hana pono no ka poʻe ma nā mokupuni mamao, nā moku ukana o waho, a me nā kahua hoʻokele e kokoke ana i ka wai," kākau ʻo Brandon.
Ua kākau ʻo Audrey Carlton, ka mea kākau moʻolelo Motherboard, ua hoʻomohala nā mea noiʻi MIT "he mea kānana ʻole, hiki ke hoʻohana i nā māla uila i hana ʻia e ka lā e pale aku i nā mea i hoʻopaʻa ʻia e like me ka paʻakai, ka bacteria a me nā maʻi."He pilikia e ulu ana ka nele no kēlā me kēia ma muli o ka piʻi ʻana o ka ʻilikai.ʻAʻole mākou makemake i ka wā e hiki mai ana, akā makemake mākou e kōkua i ka poʻe e mākaukau no ia.
Hiki i nā mea noiʻi MIT ke hoʻohua i ka wai inu i kahi mea hoʻoheheʻe ʻia e ka lāpā o kahi pihi, e like me Tony Ho Tran o The Daily Beast."ʻAʻole hilinaʻi ka hāmeʻa i nā kānana e like me nā mea hana wai maʻamau," kākau ʻo Tran."Ma ka mea, e hoʻokahe i ka wai e wehe i nā minerala, e like me nā ʻāpana paʻakai, mai ka wai."
