TDS. RO. GPD. NSF 53. Mena kua whakaaro koe me whiwhi tohu pūtaiao koe hei mārama ki te whārangi hua o te kaihoroi wai, ehara i te mea ko koe anake. He maha ngā wā ka rite ngā rauemi hokohoko ki te mea kei roto i te waehere, ā, he uaua ki te mōhio he aha te mea e hokona ana e koe. Me wetewete tātou i ngā kupu matua kia taea ai e koe te hokohoko me te māia.

Tuatahi, He aha te Hiranga o tēnei?

Ehara te mōhio ki te reo i te mea he tohunga hangarau. Engari he mea hei whakakore i te kohu hokohoko mā te pātai i tētahi pātai māmā: "Ka whakaotihia e tēnei mīhini ngā raruraru motuhake memywai?” Ko ēnei kupu ngā taputapu hei kimi i tāu whakautu.

Wāhanga 1: Ngā Kupu Whakarāpopoto (Ngā Hangarau Matua)

• RO (Reverse Osmosis): Koinei te mīhini hiki taumaha. Whakaarohia he kiriuhi RO he tātari tino angiangi e panaia ana te wai i raro i te pēhanga. Ka tangohia e ia te nuinga o ngā poke, tae atu ki ngā tote rewa, ngā konganuku taumaha (pēnei i te mata), ngā huaketo, me ngā huakita. Ko te painga ko te tango i ngā kohuke whai hua, ā, ka moumou wai i roto i te tukanga.
• UF (Ultrafiltration): He whanaunga ngāwari ake ki te RO. He nui ake ngā pūwero o te kiriuhi UF. He pai mō te tango i ngā matūriki, te waikura, ngā huakita, me ngā pūwero, engari kāore e taea te tango i ngā tote rewa, i ngā konganuku taumaha rānei. He tino pai mō te wai kua rongoatia e te kaunihera, ko te whāinga matua he pai ake te reka me te haumaru me te kore e moumou i te pūnaha RO.
• UV (Ultraviolet): Ehara tēnei i te tātari; he patu huakita. Ka whakangaromia e te mārama UV ngā moroiti pēnei i te huakita me te huaketo, ka whakangaromia ō rātou DNA kia kore ai e taea te whakaputa uri. Kāore he pānga ki ngā matū, ki ngā konganuku, ki te reka rānei. Tata tonu te whakamahinga.i roto i te whakakotahitangame ētahi atu tātari mō te whakahoromata whakamutunga.
• TDS (Total Dissolved Solids): He ine tēnei, ehara i te hangarau. Ka ine ngā mita TDS i te kukū o ngā matū kore-waro me ngā matū waro katoa kua rewa i roto i tō wai—ko te nuinga he kohuke me te tote (konupūmā, konupora, pāhare pākawa, konutai). Ko te TDS teitei (hei tauira, neke atu i te 500 ppm) he tikanga he hiahia koe ki tētahi pūnaha RO hei whakapai ake i te reka me te whakaiti i te unahi. He Tirohanga Matua: Ko te iti o te TDS ehara i te mea he haumaru te wai—tērā pea kei roto tonu he huakita, he matū rānei.
• GPD (Karani ia Rā): Koinei te whakatauranga kaha. E whakaatu ana i te maha o ngā karani wai parakore ka taea e te pūnaha te whakaputa i roto i ngā haora 24. He pai te pūnaha 50 GPD mō te tokorua, engari ko te whānau tokowhā ka hiahia pea ki te 75-100 GPD kia kore ai e tatari kia whakakīia te tāke.

Wāhanga 2: Ngā Tiwhikete (Ngā Hiri Tiaki)

Koinei te huarahi e whakamana ai koe i ngā kereme a te kamupene. Kaua e whakawhirinaki noa ki ā rātou kōrero.

• Ngā Paerewa NSF/ANSI: Koinei te paerewa koura. Ko te tikanga o te tiwhikete NSF motuhake kua whakamatautauria te hua, ā, kua whakamātauhia tōna kaha ki te whakaiti i ngā poke motuhake.
  • NSF/ANSI 42: E whakamana ana ka whakaitihia e te tātari te haukini, te reka, me te kakara (ngā āhuatanga ataahua).
  • NSF/ANSI 53: E whakamana ana ka whakaitihia e te tātari ngā poke hauora pēnei i te mata, te mercury, ngā cysts, me ngā VOC.
  • NSF/ANSI 58: Ko te paerewa motuhake mō ngā pūnaha Osmosis Whakamuri.
• Hiri Koura WQA: Ko te tiwhikete a te Water Quality Association tētahi atu tohu rongonui, he rite ki te NSF.
• Me aha: I te wā e hokohoko ana, tirohia te tohu me te nama tiwhikete tuturu kei runga i te hua, i te paetukutuku rānei. Kāore he rite o te kereme koretake pēnei i te "e tutuki ana i ngā paerewa NSF" ki te tiwhikete mana.

Wāhanga 3: Ngā Kupu rongonui noa (engari he pōhēhē)

• Wai Kawakore/Wai Kohuke: Ka tāpirihia e ētahi tātari ngā kohuke ki roto i te wai RO, ka whakamahia rānei he uku motuhake hei whakanui ake i te pH (kia iti ake te waikawa). Kei te tautohetia ngā painga hauora e kīia ana, engari he tokomaha te hunga e pai ake ana ki te reka.
• ZeroWater®: He ingoa waitohu tēnei mō ngā ipu e whakamahi ana i te tātari 5-wāhanga tae atu ki te kapia whakawhiti-katote, he mea tino pai ki te whakaiti i te TDS mō te wai tino parakore. Ko te tikanga me whakakapi pinepine ā rātou tātari i ngā wāhi wai mārō.
• Tātari Wāhanga (hei tauira, Wāhanga-5): Kāore e pai ake te maha o ngā wāhanga. Ka whakaahuahia e rātou ngā wāhanga tātari motuhake. Ko te pūnaha RO wāhanga-5 noa pea: 1) Tātari paru, 2) Tātari waro, 3) Kiriuhi RO, 4) Tātari muri-waro, 5) Tātari kawakore. Kia mārama ki te mahi a ia wāhanga.

Tō Pepa Tinihanga Whakahē mō te Hoko

1. Whakamātauria Tuatahi. Tikina he mita TDS māmā, he rīpene whakamātautau rānei. He nui te TDS/kohuke? He kaitono RO pea koe. Kei te hiahia noa koe ki te reka/kakara pai ake? He rawaka pea he tātari waro (NSF 42).
2. Whakatauritehia te Tiwhikete ki te Raru. He āwangawanga mō te mata, mō ngā matū rānei? Tirohia noa ngā tauira me te NSF/ANSI 53, 58 rānei. Kaua e utu mō tētahi pūnaha whai tiwhikete hauora mēnā ko te whakapai ake i te reka anake te mea e hiahiatia ana e koe.
3. Kaua e aro ki ngā kereme koretake. Kaua e aro ki te "whakakore paitini" te "whakakaha rānei i te wairua." Kia arotahi ki te whakaiti i ngā poke kua whakamanahia, kua tohua.
4. Mahia te Pāngarau Pūmanawa. Ka puta he 0.035 karani ia meneti i roto i te pūnaha 50 GPD. Mena ka neke atu i te 45 hēkona te roa o te whakakī i tētahi pounamu 1-rita, koinā te mea e tika ana mōu. Kōwhiria he GPD e rite ana ki tō manawanui.
