Tuatahi, he tata te tawhiti i waenga i te taputapu wehewehe hau me te taputapu whakaora whanariki, ā, ko ngā hau H2S me SO2 e puta ana i roto i te hau putanga o te whakaora whanariki ka pāngia e te ahunga hau me te pēhanga taiao, ā, ka mimitihia ki roto i te pēhi hau mā te tātari horoi-ake o te wae wehenga hau ka tomo ki te pūnaha purenga, ka hua ake he hekenga āta haere o te mahi a te tātari ngota. Kāore i te tino nui te nui o te hau waikawa i roto i tēnei wāhanga, engari i roto i te tukanga pēhi pēhi hau, kāore e taea te wareware i tōna kohikohinga. Tuarua, i roto i te tukanga whakaputa, nā te turuturu o roto o te whakawhiti wera, ka turuturu te hau waikawa e puta ana i te hau tukatuka hau mata me te tukanga horoi me te whakaora methanol pāmahana iti ki roto i te pūnaha wai rere. Nā te huringa o te wera huna o te mimiti i muri i te pa atu o te hau maroke e tomo ana ki te pourewa whakamatao hau ki te wai horoi, ka heke te pāmahana o te hau, ā, ka tau te hau H2S me SO2 i roto i te wai rere ki roto i te pourewa whakamatao hau, kātahi ka tomo ki te pūnaha purenga me te hau. I paitinihia te tātari ngota, ā, i whakakorengia, ā, i whakaitihia te kaha mimiti.
I te nuinga o te wā, me tino tātarihia te taiao e karapoti ana i te tātari horoi-ā-roto o te waeine wehewehe hau i ia wā, kia kore ai te hau waikawa e uru ki te pūnaha kōpeketanga me te hau. Hei tāpiri, kua tutukihia te tauira me te tātari auau o ngā momo whakawhiti wera i roto i ngā taputapu whakapūngao me ngā taputapu whakahiato i te wā tika kia kitea ai te turuturu o roto o ngā taputapu, kia kore ai hoki te reo whakawhiti wera e tuku parahanga, kia pai ai te kounga o ngā paerewa wai e rere ana, kia haumaru ai, kia pumau ai hoki te mahi a te tātari ngota.
