ʻAʻole. He mau ʻōnaehana mālama wai ikaika a maikaʻi hoʻi ka Ultrafiltration (UF) a me ka reverse osmosis (RO), akā ʻokoʻa ʻo UF mai RO ma kekahi mau ʻano koʻikoʻi:
Kānana i nā mea paʻa/ʻāpana liʻiliʻi e like me 0.02 microns, me nā bacteria. ʻAʻole hiki ke wehe i nā minelala i hoʻoheheʻe ʻia, TDS a me nā mea i hoʻoheheʻe ʻia mai ka wai.
E hana i ka wai ma ke noi - ʻaʻohe pono o nā pahu mālama
ʻAʻohe wai ʻōpala i hana ʻia (mālama wai)
Holo mālie i ka voltage haʻahaʻa - ʻaʻohe pono o ka uila
He aha ka ʻokoʻa ma waena o ka ultrafiltration a me ka osmosis hoʻohuli?
ʻAno ʻenehana membrane
Hoʻopau wale ka Ultrafiltration i nā ʻāpana a me nā mea paʻa, akā hana ia pēlā ma kahi pae microscopic; ʻo ka nui o ka pore membrane he 0.02 microns. Ma ke ʻano o ka ʻono, mālama ka ultrafiltration i nā minelala, kahi e hoʻopilikia ai i ka ʻono o ka wai.
Hoʻopau ka osmosis hoʻohuli i nā mea āpau i loko o ka wai, me ka hapa nui o nā minelala i hoʻoheheʻe ʻia a me nā mea paʻa i hoʻoheheʻe ʻia. He mau membrane semipermeable nā membrane RO me ka nui o ka pore ma kahi o 0.0001 microns. No laila, aneane "ʻala ʻole" ka wai RO no ka mea ʻaʻohe ona minelala, nā kemika, a me nā hui organik a me nā inorganic ʻē aʻe.
Makemake kekahi poʻe i nā minelala i loko o ko lākou wai (mahalo ʻo UF), makemake kekahi poʻe i ka maʻemaʻe loa a me ke ʻala ʻole o ko lākou wai (mahalo ʻo RO).
He membrane hollow fiber ko ka Ultrafiltration, no laila he kānana mechanical pae maikaʻi loa ia e ālai ana i nā ʻāpana a me nā mea paʻa.
ʻO ka osmosis hoʻohuli kahi hana e hoʻokaʻawale i nā molekala. Hoʻohana ia i kahi membrane semi-permeable e hoʻokaʻawale i nā inorganics a me nā inorganics i hoʻoheheʻe ʻia mai nā molekala wai.
I LOKOwai ʻaʻai/Hōʻole
ʻAʻole hoʻopuka ka Ultrafiltration i ka wai hoʻoneoneo (nā huahana ʻōpala) i ka wā o ke kaʻina kānana *
I loko o ka osmosis hoʻohuli, aia ka kānana cross-flow ma o kahi membrane. ʻO ke ʻano kēia, komo kahi kahawai wai (permeate/product water) i loko o ka pahu mālama a komo kahi kahawai wai e loaʻa ana nā mea haumia a me nā mea inorganic i hoʻoheheʻe ʻia (ʻōpala) i loko o ka lua. ʻO ka maʻamau, no kēlā me kēia 1 galani o ka wai osmosis hoʻohuli i hana ʻia, hoʻouna ʻia 3 galani i ka lua.
E hoʻouka
ʻO ke kau ʻana i kahi ʻōnaehana osmosis hoʻohuli e pono ai kekahi mau pilina: nā laina hoʻolako wai, nā laina hoʻokuʻu wai ʻino, nā pahu mālama, a me nā faucets ea.
Ke hoʻouka nei ʻO kahi ʻōnaehana ultrafiltration me nā membrane flushable (ʻo ka mea hou loa i ka ʻenehana ultrafiltration*) e pono ai kekahi mau pilina: kahi laina hoʻolako hānai, kahi laina hoʻokahe no ka holoi ʻana i nā membrane, a me kahi faucet i hoʻolaʻa ʻia (nā noi wai inu) a i ʻole ka laina hoʻolako puka (hale holoʻokoʻa a i ʻole ka noi kalepa).
No ka hoʻouka ʻana i kahi ʻōnaehana ultrafiltration me ka ʻole o nā membrane flushable, e hoʻohui wale i ka ʻōnaehana i ka laina hoʻolako hānai a me kahi piula wai i hoʻolaʻa ʻia (wai inu) a i ʻole ka laina hoʻolako puka (no nā noi hale noho a ʻoihana paha).
ʻO wai ka mea maikaʻi, ʻo RO a i ʻole ʻo UF?
ʻO ka osmosis hoʻohuli a me ka ultrafiltration nā ʻōnaehana kūpono a ikaika loa i loaʻa. ʻO ka mea hope loa, ʻo ka mea ʻoi aku ka maikaʻi he makemake pilikino ia e pili ana i kou kūlana wai, nā makemake ʻono, ka wahi, ka makemake e mālama i ka wai, ke kaomi wai, a pēlā aku.
Aia ka Mea hoʻomaʻemaʻe wai RO a me Mea hoʻomaʻemaʻe wai UF no kāu koho.
