Alumina whakahohe

Kua tutuki he whanaketanga hou i roto i te hangarau tango-pūhaumāota mā te whanaketanga o tētahi momo kaikōmiwaiwai hou kua whakarerekētia hei tango-pūhaumāota. Kua whakaatuhia e tēnei kaikōmiwaiwai hou ngā āhuatanga tango-pūhaumāota kua whakarei ake i roto i te wai whenua me te wai mata, he mea nui tēnei hei aro atu ki ngā taumata morearea o te poke o te pūhaumāota e tū hei mōrearea nui ki te hauora o te tangata.

Kua honoa te nui rawa o te fluoride i roto i te wai inu ki ngā momo raruraru hauora, tae atu ki te fluorosis niho me te angaanga, me ētahi atu mate hauora kino. I te mea kāore e whai hua ngā tikanga maimoatanga wai tuku iho ki te tango i te fluoride mai i te wai, ko te whakawhanaketanga o tētahi mea mimiti whai hua ka tuku i te tumanako hou ki te whakatika i tēnei take nui.

Kua whakaatuhia e te adsorbent alumina kua whakarerekētia te waikawa auaha ngā hua whakamīharo i roto i ngā rangahau defluoridation, me ōna āhuatanga kinetic me isotherm e whakaatu ana i tōna whai huatanga ki te tango i te fluoride mai i te wai. He pai ake te kōwhiringa o tēnei putanga hou hei whakarite i te haumaru o te wai inu, inā koa i ngā rohe he nui te āwangawanga mō te poke o te fluoride.

Ko te tikanga tango mimiti e whakamahia ana e te kaimomomi alumina hou he otinga utu-whai hua, he otinga whai hua hoki mō ngā hapori e pāngia ana e te poke o te fluoride i roto i ō rātou puna wai. He rerekē ki ētahi atu tikanga e whai tukanga uaua ana, e nui ana hoki ngā utu, ko te whakamahinga o te kaimomomi alumina kua whakarerekētia te waikawa ka whakarato i tētahi huarahi māmā ake, ngāwari ake hoki ki te whakatika i ngā taumata fluoride i roto i te wai.

Hei tāpiritanga, ko ngā āhuatanga tango-pūhaumāota kua whakarei ake o te mea mimiti hou e tuku ana i tētahi otinga pumau mō te maimoatanga wai, nā te mea ka taea te whakauru ngāwari ki roto i ngā pūnaha maimoatanga wai o nāianei me te kore he whakarerekētanga nui, he haumitanga nui rānei. Nā tēnei ka waiho hei kōwhiringa whai hua mō ngā hapori me ngā rohe e raru ana ki te whawhai ki te poke o te pūhaumāota i roto i ō rātou puna wai.

Ko te whanaketanga o te mea mimiti alumina kua whakarerekētia te waikawa he whanaketanga nui i roto i te ao o te maimoatanga wai me te hauora tūmatanui. Mā te tuku i tētahi otinga whai hua me te whai hua ki te wero o te nui rawa o te fluoride i roto i te wai, ka taea e tēnei auahatanga te whai pānga pai ki te oranga me te oranga o ngā hapori huri noa i te ao.

I te heke mai, he mea nui te rangahau me te whanaketanga atu i tēnei wāhanga hei whakapai ake i te whakamahinga o te adsorbent hou me te tūhura i ōna tono pea i roto i ngā āhuatanga maimoatanga wai rerekē. Mā te whakapau kaha tonu me te haumi ki tēnei hangarau, e tūmanakohia ana ka taea te whakaiti i te take o te poke o te fluoride i roto i te wai, kia pai ai te inu wai haumaru, ma hoki mō te katoa.
