Ko ngā mea whakamaroke wai he matū e mimiti ana i te makuku mai i te taiao, ā, he mea nui ēnei i roto i ngā momo ahumahi hei tiaki i te kounga o ngā hua me ngā rauemi. I roto i ngā mea whakamaroke wai maha e wātea ana, ko te alumina whakahohe te mea e tū motuhake ana nā ōna āhuatanga ahurei me tōna maha o ngā whakamahinga.
He momo waikura konumohe tino pūwero te alumina whakahohe, i hangaia mā te whakamahana i te hauwai konumohe ki te wera. Ka whakarei ake tēnei tukanga i tōna horahanga mata me te kaha mimiti, ka waiho hei whakamaroke whai hua. Me te horahanga mata tae atu ki te 300 m²/g, ka taea e te alumina whakahohe te mimiti i te nui o te mamaoa wai, ka pai mō ngā tono e tino hiahiatia ana te whakahaere i te makuku.
Ko tētahi o ngā whakamahinga matua o te alumina whakahohe ko te whakamaroke i ngā hau me ngā wai. I roto i ngā taiao ahumahi, ka whakamahia pinepine hei tango i te makuku mai i te hau kōpeke me te hau māori, hei ārai i te waikura me te whakarite i te whai huatanga o ngā taputapu. Hei tāpiri, ka whakamahia te alumina whakahohe ki te hanga matū me ngā rongoā parakore teitei, ahakoa he iti noa te makuku ka taea te whakararu i te kounga o te hua.
He mea nui anō hoki te mahi a te alumina whakahohe i roto i te umanga maimoatanga wai. He whai hua ki te tango i te fluoride me te arsenic i roto i te wai inu, ā, he mea nui hoki ki ngā pūnaha horoi wai. Ko tōna kaha ki te mimiti i ngā poke me te pupuri i te tere whakahekenga iti ka whakarite kia noho haumaru te wai kua rongoatia mō te inu.
Heoi anō, ka taea te whakamahi anō i te alumina kua whakahohehia. Ka taea te hanga anō mā te whakamahana, ka taea ai te tuku i te makuku kua mimitihia, ā, ka taea te whakamahi anō. Nā tēnei āhuatanga, ehara i te mea he iti noa te utu engari he pai hoki mō te taiao, nā te mea ka whakaitihia te para e pā ana ki ngā whakamaroke kotahi te whakamahinga.
Hei whakamutunga, he mea whakamaroke kaha te alumina kua whakahohehia, he maha ngā whakamahinga puta noa i ngā ahumahi rerekē. Nā ōna kaha ki te mimiti i te makuku, me tōna āheinga ki te whakamahi anō, he taputapu tino nui hei pupuri i te kounga me te haumaru o te hua i roto i ngā taiao tairongo ki te makuku.
