Kāhea ʻia ka kānana pololei

Kāhea ʻia ka kānana pololei, ʻo ia hoʻi, ua māhele ʻia nā ʻāpana haumia i wehe ʻia mai ka wai ma luna o ka ʻili o ka mea kānana ma mua o ka puʻunaue ʻana i loko o ka mea kānana.Hoʻohana nui ʻia ia no ka wehe ʻana i nā mea paʻa i hoʻokuʻu ʻia, ma mua o ka reverse osmosis a me ka electrodialysis, a ma hope o ka kānana multi-media, e hana ana i kānana palekana.Aia ka kānana pololei i kahi hale kānana a me kahi mea kānana i hoʻokomo ʻia i loko.

I ka wā e hana ai, komo ka wai i ka mea kānana mai waho o ka mea kānana, a ua paʻa nā ʻāpana haumia i loko o ka wai ma waho o ka mea kānana.Hoʻokomo ka wai kānana i ka mea kānana a alakaʻi ʻia ma waho o ka pipeline ohi.ʻO ka filtration pololei o ka kānana precision maʻamau he 1.1-20μm, hiki ke hoʻololi i ka pololei o ka mea kānana ma ka makemake, a ʻo ka pūpū ka nui o nā hale ʻelua: ke kila kila a me ke aniani kūlohelohe.Pono e holoi ʻia ka kānana pololei i hoʻokahi lā i ka wā e hoʻohana ai.

ʻO ka mea kānana pololei ka mea e hoʻokō ai i ka kānana a me ka hoʻokaʻawale ʻana o nā ʻāpana paʻa, nā mea i hoʻokuʻu ʻia a me nā microorganism i loko o ka wai a i ʻole ke kinoea ma o kāna mea kūikawā a me kāna ʻano.

Hoʻokumu pinepine ʻia ka mea kānana pololei i nā mea kānana multi-layer, me nā mea fiber, nā mea membrane, nā seramika a pēlā aku.Loaʻa i kēia mau mea ka nui o nā pore a me nā waiwai kānana molecular, a hiki iā ia ke pale i nā ʻāpana a me nā microorganism o nā nui like ʻole.

Ke hele ka wai a i ʻole ke kinoea i loko o ka kānana pololei, ʻo ka hapa nui o nā ʻāpana paʻa, nā mea i hoʻokuʻu ʻia a me nā microorganism e pāpā ʻia ma ka ʻili o ka kānana, a hiki i ka wai maʻemaʻe a i ʻole ke kinoea ke hele i loko o ka kānana.Ma o nā pae like ʻole o nā mea kānana, hiki i ka mea kānana pololei ke hoʻokō pono i ka kānana maikaʻi ʻana o nā ʻāpana a me nā microorganism o nā nui like ʻole.

Eia kekahi, hiki i ka mea kānana pololei ke hoʻonui i ka hopena kānana ma o ka adsorption charge, ka kānana ʻili a me nā mīkini kānana hohonu.No ka laʻana, ua hāʻawi ʻia ka ʻili o kekahi mau kānana pololei me ka uku uila, hiki ke hoʻopili i nā microorganisms a me nā ʻāpana me nā kumu kūʻē;ʻO ka ʻili o kekahi mau mea kānana pololei he pores liʻiliʻi, hiki ke pale i ka hele ʻana o nā ʻāpana liʻiliʻi ma o ka hopena o ka ʻili;Aia kekahi mau kānana pololei me nā pores nui a me nā papa kānana hohonu, hiki ke hoʻemi pono i nā pollutants i loko o nā wai a i ʻole nā ​​​​gasana.

Ma keʻano laulā, hiki i ka mea kānana pololei ke kānana pono a me ka hoʻokaʻawale ʻana i nā mea paʻa paʻa, nā mea i hoʻokuʻu ʻia a me nā microorganism i loko o ka wai a i ʻole ke kinoea ma ke koho ʻana i nā mea kānana kūpono a me nā hale, i hui pū ʻia me nā mīkini kānana like ʻole.
