He mea tino nui te inu wai mā ki tō hauora. Nā te whānui o te parahanga o ngā wai, kāore te wai puna e waiho hei puna pono mō te wai. He maha ngā wā kua pāngia te tangata e te mate nā te inu wai puna kāore i tātarihia. Nō reira, he mea nui te whai i tētahi taputapu horoi wai kounga teitei mō ia whānau, ahakoa ehara i te mea pai rawa atu. Heoi anō, he maha ngā taputapu horoi wai e whakamahi ana i ngā pūnaha horoi wai rerekē kei te mākete. Nō reira, mā te whiriwhiri i te tātari wai tika mō tō whānau ka pōhēhē pea koe. Mā te whiriwhiri i te taputapu horoi wai tika ka taea te whakarerekē i te ao. Hei āwhina i a koe ki te whakatau tika, i whakaritea e mātou ngā pūnaha horoi wai tino rongonui, arā, te taputapu horoi wai osmosis whakamuri me te taputapu horoi wai ultraviolet.
He aha te pūnaha horoi wai o te Reverse Osmosis (RO)?
He pūnaha purenga wai tēnei e neke ana i ngā ngota wai mā roto i tētahi kiriuhi haurua-permeable. Nō reira, ko ngā ngota wai anake ka taea te neke ki tērā taha o te kiriuhi, ka waiho ngā tote rewa me ētahi atu poke. Nō reira, kāore he huakita kino me ngā poke rewa i roto i te wai purenga RO.
He aha te pūnaha horoi wai UV?
I roto i te pūnaha tātari UV, ka patua e ngā hihi UV (ultra-violet) ngā huakita kino i roto i te wai. Nō reira, kua tino horoia te wai mai i ngā mate urutā. He pai te horoi wai ultraviolet ki te hauora, nā te mea ka taea e ia te patu i ngā moroiti kino katoa i roto i te wai me te kore e pā ki te reka.
Ko tēhea te mea pai ake, te pūwhakapai wai RO, te pūwhakapai wai UV rānei?
Ahakoa ka taea e ngā pūnaha horoi wai RO me UV te tango, te patu rānei i ngā huakita kino i roto i te wai, me whai whakaaro koe ki ētahi atu āhuatanga i mua i te whakatau whakamutunga mō te hoko. Anei ngā rerekētanga matua i waenga i ngā pūnaha tātari e rua.
Ka patua e ngā tātari hihi-whero ngā mate katoa kei roto i te wai. Heoi, ka noho tonu ngā huakita mate i roto i te wai. I tētahi atu taha, ka patua e ngā mīhini horoi wai osmosis whakamuri ngā huakita, ā, ka tātarihia ngā tūpāpaku e mānu ana i roto i te wai. Nō reira, he pai ake te wai RO parakore.
Ka taea e te pūwhakapai wai RO te tango i ngā tote me ngā matū kua rewa i roto i te wai. Heoi, kāore e taea e ngā tātari UV te wehewehe i ngā totoka kua rewa i te wai. Nō reira, he pai ake te pūnaha osmosis whakamuri ki te whakamāori i te wai puna, nā te mea ehara i te huakita anake te mea e poke ana i te wai. Ka pā kino ngā konganuku taumaha me ētahi atu matū kino i roto i te wai ki tō hauora.
He pūnaha tātari mua kei roto i ngā pūwhakamātautau RO hei āwhina i a rātou ki te whakahaere i te wai paru me te wai paru. I tētahi atu taha, kāore e pai ngā tātari UV mō te wai paru. Me mārama te wai kia pai ai te patu i ngā huakita. Nō reira, kāore pea ngā tātari UV i te pai mō ngā wāhi he nui te paru i roto i te wai.
Me whakamahi hiko te pūwhakapai wai RO hei whakanui ake i te pēhanga wai. Heoi, ka taea e te tātari UV te mahi i raro i te pēhanga wai noa.
Ko tētahi atu āhuatanga nui o te whiriwhiri i tētahi taputapu horoi wai ko te utu. I ēnei rā, he tika te utu mō te taputapu horoi wai. Ka tiaki i a tātou mai i ngā mate wai, ā, ka whakarite kia kore tātou e ngaro i te kura, i te mahi rānei. Ko te utu mō te tātari RO he mea hei tautoko i tōna tiakitanga. Hei tāpiri, ka taea e te taputapu horoi wai UV te penapena i ētahi atu āhuatanga nui, pērā i te wā (he tere ake te taputapu horoi wai UV i te tātari osmosis whakamuri), ā, ka pupuri i te wai i tōna tae me tōna reka tūturu.
Heoi, ina whakaritea ngā pūwhakamāori wai RO me UV, e mārama ana he pūnaha whakamāori wai RO te pūnaha i te pūnaha UV. Ka patu huakita noa te pūwhakamāori wai ultraviolet i te wai hei tiaki i a koe mai i ngā mate wai. Heoi, kāore e taea te tango i ngā tote kino me ngā konganuku taumaha i roto i te wai, nō reira he pono ake, he whai hua ake hoki te pūnaha whakamāori wai RO. Heoi, ko te kōwhiringa haumaru ake ināianei ko te whiriwhiri i te pūwhakamāori wai ultraviolet RO mā te whakamahi i te SCMT (hangarau kiriuhi hiriwa).
