Kāo. He pūnaha maimoatanga wai kaha, whai hua hoki te Ultrafiltration (UF) me te reverse osmosis (RO), engari he rerekē a UF i te RO i roto i ētahi āhuatanga nui:
Ka tātari i ngā matūriki/totoka tae atu ki te 0.02 maikorona te rahi, tae atu ki ngā huakita. Kāore e taea te tango i ngā kohuke rewa, ngā TDS me ngā matū rewa i te wai.
Whakaputa wai i runga i te tono - kāore he tāke rokiroki e hiahiatia ana
Kāore he wai para e puta (he penapena wai)
He maeneene te oma i te ngaohiko iti - kāore he hiko e hiahiatia ana
He aha te rerekētanga i waenga i te ultrafiltration me te reverse osmosis?
Momo hangarau membrane
Ko ngā matūriki me ngā totoka anake ka tangohia e te tātaritanga-ā-rahi, engari he iti noa iho te rahi o te pūwero o te kiriuhi; ko te rahi o te pūwero he 0.02 maikorona. Mō te reka, ka mau tonu ngā kohuke i te tātaritanga-ā-rahi, ā, ka pā tēnei ki te reka o te wai.
Ka whakakorea e te osmosis whakamuri te nuinga o ngā mea katoa i roto i te wai, tae atu ki te nuinga o ngā kohuke rewa me ngā totoka rewa. He kiriuhi ā-haurua te uru o ngā kiriuhi RO, ā, ko te rahi o te pūwero he tata ki te 0.0001 maikorona. Nō reira, he tata kore "kakara" te wai RO nā te mea kāore he kohuke, he matū, me ētahi atu matū waro me ngā matū kore-waro.
Ko tā ētahi he pai ki te wai he kohuke (nā UF), ko tā ētahi he parakore, he kore kakara (nā RO).
He kiriuhi muka tuwhera tō te tātaritanga tino-rahi, nō reira he tātari ā-ringa taumata-tino-pai e aukati ana i ngā matūriki me ngā totoka.
Ko te osmosis whakamuri he tukanga e wehewehe ana i ngā ngota. Ka whakamahia he kiriuhi haurua-permeable hei wehe i ngā mea kore-waro me ngā mea kore-waro rewa mai i ngā ngota wai.
I ROTOwai mātao/Whakakore
Kāore te tātaritanga tino-rahi e whakaputa i te wai para (ngā hua para) i te wā o te tukanga tātari*
I roto i te osmosis whakamuri, ka tātarihia te rere-whakawhiti mā roto i te kiriuhi. Ko te tikanga ka uru te awa wai (wai uru/wai hua) ki te tāke rokiroki, ā, ka uru te awa wai kei roto ngā poke katoa me ngā mea kore-waro (para) ki te waikeri. I te nuinga o te wā, mō ia karani wai osmosis whakamuri ka whakaputaina, e 3 karani ka tukuna ki te waikeri.
Tāuta
Ko te tāuta i tētahi pūnaha osmosis whakamuri e hiahia ana ki ētahi hononga: ngā paipa wai, ngā paipa tuku wai para, ngā tāke rokiroki, me ngā taputapu hau āputa.
Te Tāuta He torutoru ngā hononga e hiahiatia ana mō te pūnaha tātaritanga tino pai me ngā kiriuhi ka taea te horoi (te hangarau tātaritanga tino pai hou*): he raina tuku wai, he raina waikeri hei horoi i ngā kiriuhi, me tētahi pūwero motuhake (mō ngā tono wai inu) he raina tuku wai putanga rānei (mō te whare katoa, mō ngā tono arumoni rānei).
Hei tāuta i tētahi pūnaha tātaritanga tino-rahi me te kore he kiriuhi horoi, honoa noa te pūnaha ki te raina tuku wai me tētahi puna wai motuhake (wai inu) he raina putanga rānei (mō ngā tono kāinga, pakihi rānei).
Ko tēhea te mea pai ake, ko RO, ko UF rānei?
Ko te osmosis whakamuri me te tātaritanga-rahi ngā pūnaha tino whai hua me te kaha e wātea ana. Hei whakamutunga, ko tehea te mea pai ake he mea e pai ana ki a koe i runga i te āhua o tō wai, i ō hiahia reka, i te wāhi, i te hiahia ki te penapena wai, i te pēhanga wai, me ētahi atu.
Kei reira te Pūwhakamāori wai RO me Pūwhakamāori wai UF mō tāu whiringa.
