Nō nā tata nei i whakahaerehia e NSEN Valve te whakamātautau rehu tote kūpapa o te takirere, ā, i angitu te whakamātautau i raro i te tirotiro a TUV. Ko te peita i whakamahia mō te takirere i whakamatautauria ko JOTAMASTIC 90, e hangai ana te whakamātautau ki te paerewa ISO 9227-2017, ā, ko te roa o te whakamātautau he 96 hāora.

Kei raro nei ka whakamārama pototia e au te kaupapa o te whakamātautau NSS,

Ka whakatauira te whakamātautau rehu tote i te taiao o te moana, i te āhuarangi rānei o ngā wāhi tote, makuku hoki, ā, ka whakamahia hei aromatawai i te ātete ki te waikura o ngā hua, ngā rauemi me ō rātou paparanga tiaki.

E whakamārama ana te paerewa whakamātautau rehu tote i ngā āhuatanga whakamātautau, pērā i te pāmahana, te haumākū, te kukū o te wairewa konutai pūhaumāota me te uara pH, me ētahi atu, ā, e whakaatu ana hoki i ngā whakaritenga hangarau mō te mahi a te rūma whakamātautau rehu tote. Ko ngā tikanga mō te aromatawai i ngā hua o te whakamātautau rehu tote ko: te tikanga aromatawai whakatauranga, te tikanga aromatawai pauna, te tikanga aromatawai āhua waikura, me te tikanga tātari tatauranga raraunga waikura. Ko ngā hua e hiahia ana ki te whakamātautau rehu tote ko ētahi hua whakarewa, ā, ka tirotirohia te ātete waikura o ngā hua mā te whakamātautau.

Ko te whakamātautau taiao rehu tote hangai horihori he whakamahi i tētahi momo taputapu whakamātautau me tētahi pouaka whakamātautau rehu tote-wāhi rōrahi motuhake, i roto i tōna wāhi rōrahi, ka whakamahia ngā tikanga hangai hei waihanga i tētahi taiao rehu tote hei aromatawai i te kounga o te ātete waikura o te hua ki te rehu tote. Ki te whakatauritea ki te taiao tūturu, ko te kukū tote o te pūhaumāota i roto i te taiao rehu tote ka taea te maha, te tekau rānei ngā wā o te ihirangi rehu tote o te taiao tūturu whānui, ka nui ake te tere waikura. Ka whakahaerehia te whakamātautau rehu tote o te hua, ā, ka puta te hua. Ka tino poto hoki te wā. Hei tauira, ki te whakamatautauria he tauira hua i roto i tētahi taiao whakaaturanga taiao, ka roa pea te tatari mō tōna waikura, ko te whakamātautau i raro i ngā āhuatanga taiao rehu tote hangai horihori e 24 hāora noa iho hei whiwhi i ngā hua ōrite.

Ko te whakamātautau rehu tote kūpapa (whakamātautau NSS) te tikanga whakamātautau waikura tere tuatahi, ā, ko te tikanga tino whānui te whakamahinga. Ka whakamahia he wai tote konutai pūhaumāota 5%, ka whakatikatikaina te uara pH o te wai ki te awhe kūpapa (6-7) hei wai rehu. Ko te pāmahana whakamātautau he 35℃, ā, me noho te tere whakatō o te rehu tote i waenga i te 1～2ml/80cm²·h.
