He ʻatikala e hoʻomaopopo i ka ʻokoʻa ma waena o ka microfiltration, ultrafiltration, nanofiltration, a me reverse osmosis

Alakai

Hoʻopaʻa ka microfiltration i nā ilo koko sediment, mālama ka ultrafiltration i nā minerala akā paʻa nā metala kaumaha; He liʻiliʻi a paʻakikī ka ʻike ʻana i ka nanofiltration, a hoʻomaʻemaʻe ka reverse osmosis i ka wai maʻemaʻe i ka ʻoi loa. Hoʻoholo ka filtration pololei o ka mea hoʻomaʻemaʻe wai i ka maikaʻi o ka wai, mai ka nānā ʻana a hiki i ka hoʻomaʻemaʻe ʻana i ka atomic-level, hoʻopau ka osmosis reverse i nā haumia āpau me ka pololei o 0.0001μm, a ma waena o ka inu pololei ʻana i ka wai maʻemaʻe a me ka koho mineral, ua hūnā ʻia kāu koho olakino i ka nui o ka pore o ka membrane kānana.

Nā pōmaikaʻi o nā mea hoʻomaʻemaʻe osmosis membrane maʻemaʻe: ʻO nā waiwai maloʻo maʻemaʻe → ka ʻike o nā mea hoʻomaʻemaʻe wai, hoʻokaʻawale ʻia e like me ka pololei o ka nui o ka kānana pore o ka membrane kānana a me ka hiki ke wehe i nā ion dissolved.

1. Mea hoʻomaʻemaʻe wai microfiltration (MF)

Aia ka pololei kānana ma waena o 0.1μm-10mm, hiki ke kānana i nā ʻāpana nui e like me ka sediment, rust, bloodworms, algae a me nā mea nui ʻē aʻe i loko o ka wai, akā he kānana koʻikoʻi wale nō ia a ʻaʻole hiki ke hoʻokani i ke ʻano o ka kānana ʻana i nā bacteria a me nā maʻi.

2. Mea hoʻomaʻemaʻe wai ultrafiltration (UF)

Aia ka pololei kānana ma waena o 0.01-0.1μm, hiki ke kānana i nā mea ʻino e like me ka ʻōpala, sediment, suspended solids, colloids, bacteria, a me macromolecular organic matter i loko o ka wai, a hiki ke mālama i kekahi mau mea mineral e pono ai ke kino o ke kanaka.

ʻO ka wai hoʻoheheʻe ʻia = H20 + minelala + ion metala kaumaha

3. Mea hoʻomaʻemaʻe wai Nanofiltration (NF)

Aia ka pololei kānana ma waena o ka ultrafiltration a me ka reverse osmosis, hiki ke wehe i ka pilikia o nā ion metala kaumaha. He kakaikahi wale no ma ka makeke i keia manawa.

ʻO ka wai kānana Nanofiltration = H20 + minelala

4. Mea Hoʻomaʻemaʻe Wai Osmosis (RO1)

Pololei kānana: 0.1 nanometer (0.0001 μm), hoʻokahi-kekona o ka nui o ka lauoho lauoho, reverse osmosis ka kiʻekiʻe kiʻekiʻe o ka kānana pono i loko, hiki ke kānana i nā mea haumia a pau i loko o ka wai, me ka bacteria, viruses, heavy metals, antibiotics, etc.

ʻO ka wai i kānana ʻia e ka reverse osmosis ua kapa ʻia ka wai maʻemaʻe = H20
