ʻO ka Ultrafiltration a me ka reverse osmosis nā kaʻina hana kānana wai ikaika loa i loaʻa. Loaʻa iā lāua nā waiwai kānana koʻikoʻi, akā ʻokoʻa lākou i kekahi mau ala nui. I mea e hoʻoholo ai i ka mea kūpono no kou home, e hoʻomaopopo pono kākou i kēia mau ʻōnaehana ʻelua.

Ua like anei ka ultrafiltration me ka reverse osmosis?

ʻAʻole. ʻO ka Ultrafiltration (UF) a me ka reverse osmosis (RO) he ʻōnaehana mālama wai ikaika a maikaʻi hoʻi akā ʻokoʻa ka UF mai RO ma kekahi mau ʻano koʻikoʻi:

• Kānā i nā mea paʻa / ʻāpana liʻiliʻi e like me ka 0.02 micron me ka bacteria. ʻAʻole ia e wehe i nā minerala i hoʻoheheʻe ʻia, TDS, a me nā mea i hoʻoheheʻe ʻia i ka wai.
• Hoʻopuka i ka wai ma ke koi - ʻaʻole pono kahi pahu mālama
• ʻAʻole hana i ka wai hōʻole (mālama wai)
• Hoʻohana maʻalahi ma lalo o ke kaomi haʻahaʻa - ʻaʻohe pono uila

He aha ka ʻokoʻa ma waena o UF a me RO?

ʻAno ʻenehana membrane

Hoʻopau wale ʻo Ultrafiltration i nā ʻāpana a me nā mea paʻa, akā hana ia ma kahi pae microscopic; ʻO ka nui o ka pore membrane he 0.02 micron. ʻO ka ʻono, mālama ka ultrafiltration i nā mineral e pili ana i ka ʻono o ka wai.

Hoʻopau ka reverse osmosis i nā mea a pau i loko o ka waime ka hapa nui o nā minerala i hoʻoheheʻe ʻia a me nā mea paʻa. ʻO ka membrane RO he membrane semi-permeable i loaʻa ka nui o ka pore0.0001 micron. ʻO ka hopena, ʻoi aku ka "ʻono" o ka wai RO no ka mea ʻaʻole ia mai nā minelala, kemika, a me nā mea hoʻohuihui a me nā mea ʻole.

Makemake kekahi poʻe i kā lākou wai e loaʻa i nā minelala i loko o ia mea (ʻo ia ka UF i hāʻawi ai), a makemake kekahi poʻe i kā lākou wai maʻemaʻe a ʻono ʻole (ʻo ia ka RO i hāʻawi ai).

ʻO ka Ultrafiltration he membrane pulupulu hollow no laila he kānana mīkini ma kahi pae maikaʻi loa e hoʻōki i nā ʻāpana a me nā mea paʻa.

ʻO ka reverse osmosis kahi hana e hoʻokaʻawale ai i nā mole. Hoʻohana ʻo ia i kahi membrane semi-permeable e hoʻokaʻawale i nā inorganics a me nā inorganics hoʻoheheʻe ʻia mai ka mole wai.

pahu waihona

Hoʻopuka ʻo UF i ka wai ma nā koi e hele pololei ana i kāu kīʻaha i hoʻolaʻa ʻia - ʻaʻohe pahu mālama.

Pono ʻo RO i kahi pahu mālama no ka mea e hoʻolohi loa ka wai. Lawe kahi pahu mālama i ka wahi ma lalo o kahi poho. Eia hou, hiki i nā pahu RO ke ulu i ka bacteria inā ʻaʻole i hoʻomaʻemaʻe pono ʻia.Pono ʻoe e hoʻomaʻemaʻe i kāu ʻōnaehana RO holoʻokoʻa me ka pahuma ka liʻiliʻi hoʻokahi manawa i ka makahiki.

Wai ʻōpala / Hōʻole

ʻAʻole hoʻopuka ka Ultrafiltration i ka wai ʻino (hōʻole) i ka wā o ke kaʻina kānana.*

I ka osmosis hope, aia ka kānana kea ma o ka membrane. 'O ia ho'i, ho'okahi kahawai (permeate / product water) e hele i ka pahu ho'opa'a, a ho'okahi kahawai me nā mea haumia a pau a me nā inorganics i ho'ohehe'e 'ia (reject) e hele i ka wai. ʻO ka maʻamau no kēlā me kēia 1 galani wai RO i hana ʻia,Hoʻouna ʻia nā galani 3 e hoʻokahe.

Hoʻokomo

Pono ka hoʻokomo ʻana i kahi ʻōnaehana RO e hana i kekahi mau pilina: ka laina hoʻolako hānai, laina hoʻokahe no ka wai hōʻole, kahi pahu mālama, a me kahi kīʻaha ea.

ʻO ka hoʻokomo ʻana i kahi ʻōnaehana ultrafiltration me kahi membrane flushable (ka mea hou loa i ka ʻenehana UF *) pono e hana i kekahi mau pilina: ka laina hoʻolako hānai, laina hoʻoheheʻe e holoi i ka membrane, a i kahi faucet i hoʻolaʻa ʻia (nā noi wai inu) a i ʻole laina hoʻolako puka (holo a pau. hale a i ʻole nā ​​noi pāʻoihana).

No ka hoʻokomo ʻana i kahi ʻōnaehana ultrafiltration me ka ʻole o ka membrane flushable, e hoʻopili wale i ka ʻōnaehana i ka laina lako hānai a me ka faucet i hoʻolaʻa ʻia (wai no ka inu ʻana) a i ʻole ka laina hoʻolako puka (nā hale holoʻokoʻa a i ʻole nā ​​​​noi ʻoihana).

Hiki iā UF ke hōʻemi i ka TDS?

ʻAʻole hoʻopau ka Ultrafiltration i nā mea i hoʻoheheʻe ʻia a i ʻole TDS i hoʻoheheʻe ʻia i ka wai;ʻo ia wale nō ka hoʻoemi a hoʻoneʻe i nā mea paʻa. Hiki i ka UF ke hoʻemi i kekahi mau mea paʻa i hoʻoheheʻe ʻia (TDS) ma muli o ka kānana ultrafine, akā ma ke ʻano he kaʻina ultrafiltration ʻaʻole e wehe i nā minerala i hoʻoheheʻe ʻia, nā paʻakai i hoʻoheheʻe ʻia, nā metala i hoʻoheheʻe ʻia, a me nā mea i hoʻoheheʻe ʻia i loko o ka wai.

Inā he kiʻekiʻe TDS kiʻekiʻe o kāu wai e komo mai ana (ma luna o 500 ppm) ʻaʻole ʻōlelo ʻia ka ultrafiltration; ʻO ka reverse osmosis wale nō ka mea kūpono e hoʻohaʻahaʻa i ka TDS.

ʻO wai ka maikaʻi o RO a i ʻole UF?

ʻO ka reverse osmosis a me ka ultrafiltration nā ʻōnaehana ʻoi aku ka maikaʻi a me ka ikaika i loaʻa. ʻO ka mea ʻoi aku ka maikaʻi o ka makemake pilikino e pili ana i kou kūlana wai, makemake ʻono, ākea, makemake e mālama i ka wai, kaomi wai, a me nā mea hou aku.

Nā Pūnaehana Wai inu: Ultrafiltration versus Reverse Osmosis

Eia kekahi mau nīnau nui e nīnau iā ʻoe iho i ka hoʻoholo ʻana inā ʻoi aku ka maikaʻi o ka ʻōnaehana wai inu ultrafiltration a i ʻole reverse osmosis.

1. He aha ka TDS o kou wai? Inā he helu TDS kiʻekiʻe kāu wai e komo mai ana (ma luna o 500 ppm) ʻaʻole ʻōlelo ʻia ka ultrafiltration; ʻO ka reverse osmosis wale nō ka mea kūpono e hoʻohaʻahaʻa i ka TDS.
2. Makemake ʻoe i ka ʻono o nā minerala i loko o kou wai no ka inu ʻana? (Inā ʻae: ultrafiltration). Manaʻo kekahi poʻe ʻaʻole ʻono ka wai RO i kekahi mea, a manaʻo kekahi poʻe he ʻono palahalaha a/a i ʻole he ʻawaʻawa liʻiliʻi - pehea ka ʻono iā ʻoe a maikaʻi anei?
3. He aha kāu kaomi wai? Pono ʻo RO i ka liʻiliʻi o 50 psi e hana pono - inā ʻaʻole ʻoe he 50psi pono ʻoe i ka paila hoʻoikaika. Hana maikaʻi ka Ultrafiltration ma ke kaomi haʻahaʻa.
4. Loaʻa iā ʻoe kahi makemake e pili ana i ka wai ʻino? No kēlā me kēia galani wai RO, ma kahi o 3 mau galani e hele i ka ʻauwai. ʻAʻole hoʻopuka ka Ultrafiltration i ka wai ʻino.
