He nui rawa ngā mea pai
Mō ngā rautau, kua whakamahia e ngā kaipāmu ā rātou paru hei tongi. He nui ngā matūkai me te wai i roto i tēnei tongi, ā, ka horahia noa ki ngā mara hei āwhina i te tipu o ngā hua. Heoi, ko te mahi ahuwhenua kararehe nui e whakahaere ana i te ahuwhenua o ēnei rā ka nui ake te tongi i tērā i mahia i mua i runga i te nui o te whenua.

"Ahakoa he tongi pai te paru kararehe, mā te hora i tēnei ka rere te wai, ka poke hoki i ngā puna wai utu nui," te kī a Thurston. "Ka taea e te hangarau a LWR te whakaora me te pure i te wai, me te whakaemi i ngā matūkai mai i te paru."

I mea ia mā tēnei momo tukatuka ka whakaitihia te rahinga tukatuka katoa, "ka whakarato i tētahi huarahi utu-pai, ā, he pai hoki mō te taiao mō ngā kaiwhakahaere kararehe."

I whakamārama a Thurston ko te tukanga he maimoatanga wai ā-ringa me te matū hei wehe i ngā matūkai me ngā huaketo mai i ngā paru.

"E arotahi ana ki te wehenga me te kukū o ngā matūkai totoka me ngā matūkai whai hua pērā i te whākōkī, te pāhare pāporo, te haukini me te hauota," tana kī.

Ka hopukina e ia taahiraa o te tukanga ngā matūkai rerekē, ā, kātahi, "ka whakamahia e te wāhanga whakamutunga o te tukanga he pūnaha tātari kiriuhi hei whakaora i te wai ma."

I taua wā anō, "kāore he tukunga, nō reira ka whakamahia anōtia, ka hangaruatia hoki ngā wāhanga katoa o te wai tuatahi e kohia ana, hei putanga nui, ka whakamahia anōtia i roto i te umanga kararehe," te kī a Thurston.

Ko te rauemi e pā ana he ranunga o te paru kararehe me te wai, ka tukuna ki roto i te pūnaha LWR mā te papu tīwiri. Mā te wehewehe me te mata ka tangohia ngā totoka mai i te wai. I muri i te wehenga o ngā totoka, ka kohia te wai ki roto i te tāke whakawhiti. Ko te papu e whakamahia ana hei neke i te wai ki te wāhanga tango totoka pai he rite tonu ki te papu whakauru. Kātahi ka papua te wai ki roto i te tāke whāngai o te pūnaha tātari kiriuhi.

Ka panaia te wai e te papu toremi i roto i te kiriuhi, ā, ka wehea te awa tukanga ki ngā matūkai kukū me te wai ma. Ko te takirere whakatere i te pito tuku matūkai o te pūnaha tātari kiriuhi te kaiwhakahaere i te mahi a te kiriuhi.

Ngā takirere i roto i te pūnaha
E rua ngā momo o te LWRngā takirerei roto i ana takirere pūnaha-ao mō te whakawhāiti i ngā pūnaha tātari membrane mengā takirere pōromō te noho motuhake.

I whakamārama a Thurston ko te nuinga o ngā takirere pōro he takirere PVC, e wehe ana i ngā wāhanga pūnaha mō te tiaki me te ratonga. Ka whakamahia hoki ētahi takirere iti hei kohikohi me te tātari i ngā tauira mai i te awa tukanga. Ka whakatikatika te takirere kati i te tere rere o te tātari kiriuhi kia taea ai te wehewehe i ngā matūkai me te wai ma i roto i te ōrau kua whakaritea.

"Me kaha ngā takirere o ēnei pūnaha ki te tu atu ki ngā wāhanga o roto i te paru," te kī a Thurston. "Tērā pea ka rerekē tēnei i runga i te rohe me te kararehe, engari he mea hanga ā mātou takirere katoa ki te PVC, ki te maitai kore waikura rānei. He EPDM, he rapa nitrile rānei ngā nohoanga takirere katoa," tāna tāpiri.

Ko te nuinga o ngā takirere o te pūnaha katoa ka whakahaerehia ā-ringa. Ahakoa he takirere ētahi e whakawhiti aunoa ana i te pūnaha tātari kiriuhi mai i te mahi noa ki te tukanga horoi ā-roto, ka whakahaerehia mā te hiko. Kia oti te tukanga horoi, ka whakakorea te hiko o ēnei takirere, ā, ka hoki te pūnaha tātari kiriuhi ki te mahi noa.

Ka whakahaerehia te tukanga katoa e tētahi pūmana arorau ka taea te whakarite (PLC) me tētahi atanga kaiwhakahaere. Ka taea te uru atu ki te pūnaha mai i tawhiti hei tiro i ngā tawhā pūnaha, hei hanga huringa whakahaere, me te rapurongoā.

"Ko te wero nui rawa atu e pā ana ki ngā takirere me ngā kaiwhakaoho i roto i tēnei tukanga ko te hau waikura," te kī a Thurston. "Kei roto i te wai tukanga te haukini, ā, he tino iti hoki te nui o te haukini me te H2S i roto i te hau o te whare."

Ahakoa he rerekē ngā wero e pā ana ki ngā rohe whenua me ngā momo kararehe rerekē, he rite tonu te tukanga whānui mō ia wāhi. Nā te rerekētanga ngawari i waenga i ngā pūnaha mō te tukatuka i ngā momo paru rerekē, "I mua i te hanganga o te taputapu, ka whakamatautauria e mātou ngā paru o ia kiritaki i roto i te taiwhanga hei whakatau i te mahere maimoatanga pai rawa atu. He pūnaha whaiaro tēnei," te kī a Seuss He.

Te tipu haere o te hiahia
E ai ki te Pūrongo Whakawhanake Rauemi Wai a te Kotahitanga o ngā Whenua o te Ao, e 70% o te wai māori o te ao e tangohia ana i te ahuwhenua i tēnei wā. I taua wā anō, i te tau 2050, me piki ake te whakaputanga kai o te ao mā te 70% hei whakatutuki i ngā hiahia o te 9 piriona tāngata. Ki te kore he whanaketanga hangarau, e kore e taea.

Whakatutukihia tēnei hiahia. Nā ngā rauemi hou me ngā putanga hangarau hou pērā i te hangarua wai kararehe me ngā auahatanga takirere i whakawhanakehia hei whakarite i te angitu o ēnei mahi, ko te tikanga he iti ake te nui o ngā rauemi wai utu nui o te ao, ā, ka āwhina ēnei ki te whāngai i te ao.
