He maha ngā whakamahinga me ngā whakaritenga o ngā pōro alumina whakahohe, ā, e rima ngā mahi matua ka taea te whakarapopoto.

Whakamaroke Alumini: Ko te nuinga o te wā ka whakamahia ngā pūwero kua whanaketia o ngā pōro alumina kua whakahohehia, ā, he tino kaha te kaha mimiti i te kohu wai. Kāore e rerekē te āhua, e pakaru rānei i muri i te mimiti i te wai, ā, kāore e kino ki ngā taputapu. He whānuitia te whakamahinga i roto i ngā mīhini whakapūmau hau, ngā mīhini whakamaroke me ētahi atu taputapu. Ko ngā whakatakotoranga noa ko te 3-5mm 4-6mm.

Tautoko Alumina: te nuinga o te wā ka whakamahia te hanganga nui o ngā pore me te horahanga mata motuhake o ngā pōro alumina kua whakahohehia, ā, ka whakamahia te kaha van der Waals hei mimiti i te otinga whakakorikori e hiahiatia ana ki roto i te hanganga nui o ngā pore o ngā pōro alumina kua whakahohehia, kia whakakīia ai ngā pōro alumina kua whakahohehia ki roto i tētahi tukanga motuhake. He rite tonu te mahi ki te otinga whakakorikori. He maha ngā momo whakakorikori ka taea te whakamahi, pērā i: te otinga pāhare pākawa, te otinga waro, ngā konganuku onge, ngā konganuku utu nui me ētahi atu whakakorikori rerekē, ko ngā whakatakotoranga noa ko 2-3mm.3-5mm.

Kaihoko tango fluoride alumina: Ko te nuinga o te wā ka whakamahia ngā pūwero tino nui me te horahanga mata motuhake tino nui o ngā pōro alumina kua whakahohehia. He pai te kaha mimiti ā-tinana mō te fluoride me te arsenide i roto i te otinga. Kāore he paitini, kāore hoki he kino, ā, kāore e pā ki te inu wai. Ka whakamahia i roto i ngā kaupapa tango fluoride wai whenua me te wai inu, ko te rahi noa he 2-3mm.
