ʻO ka reverse osmosis (RO) e pili ana i kahi ʻenehana e hoʻomaʻemaʻe i ka wai ma ke kaomi ʻana iā ia i loko o kahi membrane semi-permeable ma lalo o ke kaomi kiʻekiʻe.ʻO ka membrane RO kahi ʻāpana lahilahi o nā mea kānana e hoʻokaʻawale i nā mea hoʻohaumia a me nā paʻakai i hoʻoheheʻe ʻia mai ka wai inu.Aia ʻekolu papa, ʻo ia hoʻi kahi pūnaewele kākoʻo polyester, kahi micro-porous polysulfone interlayer a me kahi ʻāpana pale polyamide ultra-thin.Hiki ke hoʻohana ʻia kēia mau membrane i nā kaʻina hana ʻelua a no ka loaʻa ʻana o ka wai inu.I kēia mau lā, hoʻohana nui ʻia lākou ma ka honua holoʻokoʻa no ka hoʻomaʻemaʻe wai, ʻoiai ke hāʻawi nei ke kaʻina RO i kahi ʻano hoʻonaninani a me ke kumu kūʻai i nā ʻano hana maʻamau e like me ka distillation.Akā ʻaʻole i maʻa pono nā kānaka i nā huaʻōlelo i hoʻohana ʻia a hoʻomaopopo pono i ka ʻokoʻa ma waena o nā ʻano o nā membrane ro.
Ma ka ʻatikala o kēia lā, e kaʻana pōkole mākou i kekahi o nā huaʻōlelo i hoʻohana nui ʻia a pehea ka ʻokoʻa ma waena o nā membrane RO.Hoʻokaʻawale ʻia nā membrane HID e ka ʻano membrane, ka hoʻohana ʻana i ka membrane, ka nui, a me ka hana.Ma kā mākou pūnaewele, ua hoʻokaʻawale ʻia ka membrane i ʻekolu mau ʻāpana me ka hoʻohana ʻana i ka membrane (GPD).Hoʻokaʻawale mākou i kā mākou ro membrane e like me ka nui o ka ʻōnaehana noi a me kā lākou GDP.No nā membrane ro noho ma HID, ka laulā GPD o 50 - 200 a hiki ke mālama i ka pae kaomi o 65psi a hiki i ka 200psi kiʻekiʻe.Loaʻa iā mākou nā hiʻohiʻona ākea a i ʻole kēia mau membrane a hiki iā ʻoe ke nānā i kā mākou ʻāpana mai kā mākou pūnaewele.He kūpono kēia mau membrane a paipai ʻia e hoʻohana i nā ʻōnaehana home ro liʻiliʻi.ma muli o kā lākou pae haʻahaʻa haʻahaʻa a me nā pae gpd.
No ka meanā membrane ro kalepa ma HID, ka laulā GPD o 200 - 1000 a hiki ke hoʻopaʻa i kahi kaomi o 65psi a hiki i ka 200psi kiʻekiʻe.Loaʻa iā mākou kahi hiʻohiʻona ākea no kēia mau membrane.He kūpono kēia mau membrane no ka hoʻohana ʻana i nā wahi ākea a i nā hale keʻena, nā halemai, nā kula, nā hale hana, nā hale hana no ka mea ʻoi aku ka nui o ka GPD no kēia mau membrane ma mua o nā hale noho.Hoʻohana pinepine ʻia lākou no ka desalination o ka wai ʻili, ka wai lepo, ka wai paila, brackish me ka paʻakai ma lalo o 2000ppm.ʻO ke kolu o ka pūʻulu ʻo nā membrane ʻoihana, nui kēia i ka nui, GPD, a ua hoʻolālā ʻia no nā ʻōnaehana nui.Mai ka 780 - 11000 galani i ka lā, hiki ke hoʻohana ʻia kēia mau mea no ka desalination o ka wai kai a me ka wai brackish kiʻekiʻe a hiki ke hoʻopaʻa i ka pae kaomi o 150psi a hiki i ka 600psi kiʻekiʻe.E kaʻana like mākou i ka ʻike kikoʻī no kēlā me kēia ʻāpana i kā mākou ʻatikala aʻe.
ʻO nā huaʻōlelo koʻikoʻi i hoʻohana ʻia i ka reverse osmosis
Hoʻihoʻi - ka pākēneka o ka wai hānai ʻōnaehana membrane e puka mai ana mai ka ʻōnaehana ma ke ʻano he wai huahana a i ʻole "permeate".
Hōʻole - ka pākēneka o ka neʻe ʻana o ka solute i wehe ʻia mai ka wai hānai ʻōnaehana e ka membrane.
Passage - ke kū'ē i ka "hōʻole",ʻo ka paukū ka pakeneka o nā mea i hoʻoheheʻeʻia (contaminants) i loko o ka wai hānai iʻaeʻia e hele i loko o ka membrane.
Kahe - ʻO ke kahe o ka hānai ka nui o ka wai hānai i hoʻokomo ʻia i ka mea membrane a i ʻole ʻōnaehana membrane, maʻamau i ana ʻia i nā galani i kēlā me kēia minuke (gpm).
Kahe ʻana - ʻo ia ka nui o ke kahe ʻana o ka wai hānai ʻaʻole i hoʻopaʻa ʻia e puka i waho o ka mea membrane a i ʻole ka ʻōnaehana membrane.
Flux - ka nui o ka permeate i lawe ʻia ma kēlā me kēia ʻāpana o ka ʻāpana membrane, maʻamau i ana ʻia i nā galani no kēlā me kēia kapuaʻi square i kēlā me kēia lā (gfd) a i ʻole lita no ka mika square a me ka hola (L/m2h).
Permeate - ka wai huahana i hoʻomaʻemaʻe ʻia e kahi ʻōnaehana membrane.
Huina i hooheheeia (TDS) - i hoike pinepine ia e like me mg/lor ppm (mau hapa no ka miliona).
