Tuatahi, i mua i te mārama ki ngā taputapu horoi wai, me mārama tātou ki ētahi kupu, ki ētahi āhuatanga rānei:

① Kiriuhi RO: Ko te RO he whakarāpopototanga mō te Osmosis Whakamuri. Mā te pēhanga ki te wai, ka wehea ngā matū ririki me ngā matū kino. Kei roto i ēnei matū kino ko ngā huaketo, ngā huakita, ngā konganuku taumaha, ngā toenga chlorine, ngā chloride, me ētahi atu.

② He aha tātou ka kohuatia ai te wai i ia wā: Ka taea e te wai kohua te tango i ngā toenga o te chlorine me te chloride i roto i te wai parakore mai i ngā whare maimoatanga wai, ā, ka taea hoki te mahi hei tikanga whakamate i ngā moroiti.

③ Te whakaputanga wai kua whakatauria: Ko te whakaputanga wai kua whakatauria e tohu ana i te nui o te wai i tātarihia i mua i te whakakapinga o te kātere tātari. Mena he iti rawa te whakaputanga wai kua whakatauria, me whakakapi pinepine te kātere tātari.

④ Te ōwehenga o te wai para: Ko te ōwehenga o te nui o te wai parakore i hangaia e te pūwhakapai wai ki te nui o te wai para i tukuna i roto i te wā kotahi.

⑤ Te tere rere o te wai: I te wā e whakamahia ana, ka rere te wai parakore i tētahi tere pumau mō tētahi wā kua whakaritea. Ka puta he tata ki te 2 rita wai i ia meneti i tētahi kaiwhakapai wai 800 karamu.

I tēnei wā, ko ngā mātāpono o ngā mīhini horoi wai i runga i te mākete e ahu mai ana i te "adsorption me te interception," e rua ngā momo matua: ultrafiltration me te reverse osmosis.

Ko te rerekētanga matua i waenga i ēnei pūwhakapai wai rongonui e rua kei roto i te tika o te tātari o te membrane.

Ko te tika o te tātari o te pūwhakamāori wai membrane RO he 0.0001 maikiromita, ka taea te tātari i te nuinga o ngā poke kua whakahuatia ake nei. Ka taea te inu tika i te wai mai i te pūwhakamāori wai membrane RO. Heoi, me whakamahi hiko, ka puta he wai para, ā, he nui ake te utu.

Ko te tika o te tātari o te kiriuhi horoi wai ultrafiltration he 0.01 maikiromita, ka taea te tātari i te nuinga o ngā poke me ngā huakita engari kāore e taea te whakakore i ngā konganuku taumaha me te unahi. Kāore e hiahiatia he hiko mō tēnei momo horoi, kāore he rerenga wai para motuhake, ā, he iti te utu. Heoi, i muri i te tātari, ka noho tonu ngā katote konganuku (pērā i te konupora), ka hua ake he unahi, ā, ka mau tonu ētahi atu poke iti.
