ʻO ka membrane ultrafiltration a me ka reverse osmosis membrane nā huahana membrane kānana e hana ana ma ke kumu o ka hoʻokaʻawale ʻana o ka membrane, i hoʻohana nui ʻia ma ke kahua o ka mālama wai.Hoʻohana ʻia kēia mau huahana membrane kānana ʻelua e nā mea hoʻohana he nui nā pono mālama wai.ʻOiai ua hoʻohana ʻia nā membrane ultrafiltration a me nā membrane reverse osmosis i ke kahua o ka mālama wai, he nui nā ʻokoʻa ma waena o lākou.
ʻO ka ʻokoʻa ma waena o ka membrane ultrafiltration a me ka membrane reverse osmosis he nui loa, ʻo ia hoʻi akā ʻaʻole i kaupalena ʻia i: ka ʻokoʻa o ke kaumaha molekala o ka interception, ka ʻokoʻa o nā kūlana wai, ka ʻokoʻa o ke kahua noi, ka ʻokoʻa o ka maikaʻi o ka wai i hana ʻia a me ka ʻokoʻa i loko. kumukūʻai.Ua wehewehe ʻia kēia mau ʻokoʻa penei:
1. ʻOkoʻa i loko o ka molecular kaumaha o interception.ʻO ke kaumaha molecular interception o ka membrane reverse osmosis he> 100, hiki ke hoʻopaʻa i nā mea ola a pau, ka paʻakai i hoʻoheheʻe ʻia, nā ion a me nā mea ʻē aʻe me ke kaumaha o ka molekala ma mua o 100, i hiki ai i nā molekala wai a me nā mea me ke kaumaha mole ma lalo o 100 ke hele;ʻO ke kaumaha o ke kaumaha o ka membrane ultrafiltration he> 10000, hiki ke hoʻopaʻa ʻia i loko o nā biofilms, proteins, macromolecular substances, i hiki ai i nā paʻakai inorganic, nā mea liʻiliʻi liʻiliʻi a me ka wai ke hele i loko.Mai ka ʻokoʻa o ka molecular kaumaha o ka interception, hiki ke ʻike ʻia ʻoi aku ka kiʻekiʻe o ka filtration pololei o ka membrane reverse osmosis ma mua o ka ultrafiltration membrane.
2. ʻOkoʻa i nā kūlana wai.Ma keʻano laulā, ʻoi aku ka haʻahaʻa o nā koi turbidity o nā membrane ultrafiltration no ka wai intake ma mua o nā membrane reverse osmosis, a he liʻiliʻi ka liʻiliʻi o ka wai inu wai a me ka pH.ʻOi aku ka haʻahaʻa o nā koi o ka membrane ultrafiltration ma mua o ka membrane reverse osmosis, no laila hiki i ka membrane ultrafiltration ke kū i ka wai me ka maikaʻi o ka wai.
3. Nā ʻokoʻa ma nā kahua noi.ʻOiai ʻo ka ultrafiltration membrane a me ka reverse osmosis membrane nā kānana e hana ana ma ke kumu o ka wehe ʻana o ka membrane, ʻokoʻa loa lākou i nā kahua noi ma muli o nā kumu he nui e like me ka filtration pololei, ka hoʻolālā ʻōnaehana, a me nā ʻano hana.Hoʻohana nui ʻia ka membrane reverse osmosis i ka desalination wai brackish, ka hoʻomākaukau ʻana i ka wai maʻemaʻe, ka hoʻokaʻawale kūikawā a me nā māla ʻē aʻe, hoʻohana nui ʻia ka membrane ultrafiltration i ka mālama ʻana i ka wai, ka hoʻomākaukau ʻana i ka wai maʻemaʻe a me ka hana ʻana i ka wai inu a me nā māla ʻē aʻe.
4. ʻokoʻa i ka maikaʻi o ka wai i hana ʻia.ʻO ka maikaʻi o ka wai i hana ʻia e pili nui i ka pololei kānana o ka membrane kānana a me ka maikaʻi o ka wai intake, ʻaʻole ʻoi aku ka kiʻekiʻe o ka membrane osmosis reverse ma mua o ka membrane ultrafiltration i ka pololei filtration, ʻoi aku ka maikaʻi o ka wai intake ma mua o ka membrane ultrafiltration. , no laila ʻoi aku ka maikaʻi o ka wai o ka membrane reverse osmosis ma mua o ka ultrafiltration membrane, a i ʻole ka liʻiliʻi o nā haumia, ʻoi aku ka maʻemaʻe.
5. ʻOkoʻa kumu kūʻai.He nui nā ʻano o nā membranes Ultrafiltration a me nā membrane reverse osmosis, akā ma ka laulā, ʻoi aku ka maikaʻi o ke kumukūʻai o nā membrane reverse osmosis ma mua o nā membrane ultrafiltration.
ʻO Toption Machinery kahi mea hana nui o nā lako hoʻomaʻemaʻe wai.Ua ʻike ʻia a hoʻomaikaʻi ʻia e nā mea kūʻai aku he nui nā mea kūʻai aku ʻo Toption Machinery no kāna ʻenehana holomua, nā mea kiʻekiʻe kiʻekiʻe, ka hana paʻa a me ka lawelawe ma hope o ke kūʻai aku.I ka wā e hiki mai ana, e hoʻomau ka Toption Machinery i ka hoʻonui ʻana i ka noiʻi a me ka hoʻomohala ʻana, e hoʻomaikaʻi mau i ka hana huahana a me nā lawelawe, a hāʻawi i nā mea kūʻai aku me nā mea hoʻomaʻamaʻa wai kiʻekiʻe kiʻekiʻe, i mea e hoʻoikaika ai i ka hoʻomohala ʻana i ka ʻoihana ʻoihana wai wai o Kina.
