Ko tēhea te mea pai ake? Te tātari UF, te tātari RO rānei hei horoi wai.
I tēnei wā, e rua ngā momo pūwero wai kei te mākete, ko tētahi he pūwero wai tātari-tino, ko tētahi he pūwero wai osmosis whakamuri. Ko te rerekētanga nui i waenga i ngā momo pūwero wai e rua ko te rerekētanga o te tika o te tātari. Ka whakamahia e ngā pūwero wai tātari-tino ngā kiriuhi tātari-tino, ka taea te whakatutuki i te tika tātari o te 0.01 microns, ā, ka taea te tātari i te nuinga o ngā poke i roto i te wai, engari kāore e taea te tātari i te kawakore wai, nō te wai kohuke. Ko te wāhanga matua o te pūwero wai osmosis whakamuri ko te kiriuhi RO. Ka taea e te tika tātari o te kiriuhi RO te eke ki te 0.0001 μm, ā, ko ngā ngota wai anake ka taea te haere. Nō reira, ko te wai parakore taketake i whiwhihia i muri i te tātari, kāore e puta he unahi i roto i te ipu.
Mō tēnei kōwhiringa, ka taea te whakatau i runga i te kounga o te wai o tō rohe. Mena he pai te kounga o te wai o te rohe, ā, he iti noa te kawakawa wai, ka taea e koe te whiriwhiri i te pūwhakapai wai tātari-tino, he mea ohanga, he utu hoki. Mena he kino te kounga o te wai o te rohe, ā, he nui rawa te kawakawa wai, ka taea e koe te whiriwhiri i te pūwhakapai wai osmosis whakamuri.

Tātari UF Puritia ngā kohuke whai hua, Kore he wai para.
Te tiaki haumaru, Te tiaki i te haumaru wai
Maukati tamariki, Ārai mō te koropupū maroke me te wera rawa, Whakamaumahara mō te korenga o te wai,

Mahi horoi unahi
Ka tae te whakamahinga kohikohi ki te 10 hāora, ka mura te rama tango tauine hei whakamahara i te horoinga tauine.
