I te mea kei te piki haere tonu ngā āwangawanga o te ao mō te korenga o te wai me te parahanga, kua kaha ake te rapu i ngā hangarau maimoatanga wai whai hua, utu-whai hua, me te pumau. Kei mua i tēnei rapunga te alumina (Al₂O₃), inā koa i roto i ōna āhua whakahohe me ōna āhua nano-hanganga, kua puta ake nei hei rauemi tūāpapa mō te purenga wai inu, te maimoatanga wai para ahumahi, me te whakarite i te haumaru taiao.
Te Mana o te Porosity: Alumina Whakahohe
Ko te alumina whakahohe, he momo waikura konumohe tino pūwero i hangaia mā te whakamaroke i te hauwai konumohe i ngā pāmahana teitei, e rongonui ana mō tōna horahanga mata motuhake nui (te nuinga o te 250–1000 m²/g) me ōna āhuatanga mimiti pai rawa atu. Ko tōna whakamahinga rongonui me te rongonui ko te tango i ngā katote fluoride mai i te wai inu.
Ko te nui rawa o te fluoride (neke atu i te 1.5 mg/L) i roto i ngā puna wai he take ā-ao e pā ana ki te neke atu i te 200 miriona tāngata, ka arahi ki ngā āhuatanga ngoikore pēnei i te fluorosis niho me te angaanga. Ka mahi te alumina whakahohe mā te chemisorption, ka hanga i ngā matatini konumohe-fluoro pumau, ka whakaiti i ngā taumata fluoride kia tutuki ai ngā paerewa pakari kua whakatakotoria e te World Health Organization (WHO). He tino whai hua puta noa i te whānuitanga o te pH (3–12) ā, he tino whai hua i raro i ngā āhuatanga tata-kore (5.5–6.5).
Haunga te pūhaumāota, he tino pai te alumina kua whakahohehia ki te tango i ngā konganuku taumaha me ngā konganuku metalloid paitini, ko te mea nui ko te arsenic. He āhuatanga ohorere hauora tūmatanui puku te poke o te arsenic i roto i te wai whenua i roto i ngā rohe maha. Ka whakaratohia e te alumina kua whakahohehia he arai pono, ka mimiti i ngā momo As(III) me As(V), ā, ka ārai i te pānga roa me ngā mate pukupuku e pā ana.
Ngā Taupānga Ahumahi me ngā Taupānga Matatau
He nui atu te whai huatanga o te alumina i tua atu i te wai inu ā-tāone. I roto i ngā wāhi ahumahi, he mea whakamaroke, he whakamaroke i te hau kōpeke, te hau māori, me ngā momo awa tukanga mā te mimiti i te makuku. Ka whakaitihia hoki te tauine me te poke i roto i te wai whāngai me ngā pūnaha whakamatao o ngā poihau.
Nā ngā whanaketanga pūtaiao o nāianei kua akiakihia te alumina ki ngā tono matatau:
Hangarau Nano: He nui rawa te horahanga o te mata me te tauhohenga o te Nano-alumina (Al₂O₃ NP). Kua angitu ngā kairangahau ki te hanga i ēnei matūriki nano mai i te pepa konumohe para, ka hangaia he mea mimiti matomato, he iti te utu, ka taea te tango i ngā katote mata (Pb²⁺) mai i te wai me te whai huatanga tae atu ki te 98%.
Te Ozonation Whakakorikori: He tautoko whakakorikori mahi-teitei te Alumina. Ka whakarei ake ngā whakakorikori pēnei i te Co₃O₄/Al₂O₃ i te tukanga ozonation, ka tere te whakaheke i ngā poke waro pumau, tae atu ki ngā toenga rongoā i roto i te wai para, he nui atu i ngā kaha o te ozonation anake.
Hangarau Kiriuhi: Nā te whakaurunga o ngā matūriki nano γ-alumina mesoporous ki roto i ngā kiriuhi nanofiltration kiriata-angiangi (TFN) kua tino hurihia te tango tote i roto i te wai parakore. E toru ngā pikinga o te rere o te wai i roto i ēnei kiriuhi kua whakarerekētia, me te pupuri tonu i ngā reiti whakakore tote tino pai (tae atu ki te 98.4%), ā, he tino whai hua mō te whakangawari me te purenga wai.
Ngā Painga me te Oranga Tonu
Ko tētahi painga matua o te alumina ko tōna pumau. Kāore i rite ki te nuinga o ngā tātari whakamahi kotahi, ka taea te whakahou i te alumina kua whakahohehia. Kia tae ki tōna kaha mimiti, ka taea te horoi matū me te whakamahi anō mō ngā huringa maha, ka whakaitihia ngā utu whakahaere me te para taiao. Ko tōna pumau matū, te kaha miihini, me te ātete ki te pakū ka whakarite kia roa te ora ratonga i roto i ngā taiao maimoatanga uaua.
Te Tirohanga ki Mua
I te ao e whakataetae ana ki ngā wero wai e piki haere ana te uaua, ka whānui haere te tūranga o te alumina. Kei te haere tonu te rangahau mō ngā rauemi alumina kua whakarerekētia te mata me ngā rauemi alumina hiato ki te pana i ngā rohe o te mahi, me te arotahi ki ngā poke hou me te tika me te kaha ake. Mai i te tiaki i te hauora tūmatanui mai i te fluoride me te arsenic ki te whakahohe i te whakatupuranga hou o ngā hangarau tango tote me te whakamahi anō i te wai, kei te noho tonu te alumina hei toa nui me te whanake haere i roto i te whai i te ao mo te wai ma me te haumaru mo te katoa.
