E toru ngā tikanga matua:
1. Tikanga matū
He whakarapopototanga, ko tōna tikanga he tāpiri i ngā matū ki te wai para kia taea ai e te paru o roto te tauhohe, kia ngāwari ai hoki te tango atu.
Tikanga whakapūpū：TKo te kaupapa mahi o te tikanga whakapūkara he tāpiri i ngā matū ki te wai, ka meinga ngā matūriki iti kia huihui, kia hanga he putunga nui ake, kātahi ka tau ki raro i te kaha o te kaha ā-papa. Ka taea e tēnei tikanga te tango i te tae, te huakita, me ētahi mea rauropi mai i te wai. Heoi, he iti noa iho te pānga o tōna maimoatanga ki ngā matū kua rewa katoa i roto i te wai, ā, ka pāngia ngāwari te pānga o te maimoatanga e ngā rerekētanga o te pāmahana wai me te uara pH.
Tikanga whakahāora:UKa whakamahia ngā waikura (pērā i te chlorine, te ozone) hei wawahi i ngā matū paitini kia kore e kino. He pai ngā pānga o te ozone, ā, kāore he parahanga tuarua, engari he nui te utu; He mea noa te whakamahi i te chlorine, ā, he pai mō te rongoā i ngā waipara kei roto ko te phenol me te cyanide; He iti noa te pānga o te waikura o te hau, ā, he mea noa te whakamahi i roto i ngā waipara kei reira ngā parahanga ka ngāwari te waikura.
Tikanga hikohiko: Ka whakamahia te hiko hei tuku i ngā poke kia tauhohe ki te mata o te hikohiko hei tango, ā, i ētahi wā ka tāpirihia te konutai hauota hei whakarei ake i te pānga. He pai te pānga tukatuka o tēnei tikanga, engari he mārama hoki ōna ngoikoretanga: i tētahi taha, he nui te hiko e pau ana, ā, he nui ngā utu whakahaere; I tētahi atu taha, ka puta pea ētahi tauhohenga taha i te wā o te tukanga, ka hua ake he parahanga tuarua.
2. Tikanga Ā-tinana
Wehea ngā poke totoka i te wai mā ngā tikanga ā-tinana.
Ka whakamahia e te tikanga tātari ngā pāpāho tātari he moroiti ōna pūwero (pērā i ngā tātari moroiti) hei aukati i ngā totoka iri i roto i te wai.
Ko te ture whakapūpū he whakamahi i te kaha ā-papa kia taea ai e ngā matūriki taumaha i roto i te paru te tau maori ki te takere o te wai.
Mā te tikanga whakamānu hau ka whakaurua he maha o ngā mirumiru ririki ki roto i te wai, ka piri atu ki ngā matūriki poke, ka hanga he tinana mānu me te matotoru whānui he iti iho i te wai. Kātahi ka piki ake ki te mata o te wai mā te pōrewarewa, ā, ka tangohia mā te taputapu waru.
He māmā noa iho ēnei tikanga, ā, he ngāwari hoki te whakahaere, engari kāore e taea te tango i ngā poke i rewa i roto i te wai, ā, he iti noa iho ngā herenga o tō rātou whakamahinga.
3. Hangarau whakahāora whakaahua-whakaata
Mā te whakamahi i te mārama ultraviolet me ngā matū whakahāora (pērā i te hauwai peroxide), ka taea te whakangaro katoa i ngā poke uaua ki te pirau (pērā i te polychlorinated biphenyls).
Tērā tētahi tikanga e kīia ana ko te 'photocatalytic Fenton', e taea ai te whakaputa tere i te nui o ngā matū hohe, me te wawahi pai i ngā mea rauropi i raro i te mahi tahi a ngā katote mārama me te rino.
Ko tētahi atu tikanga ko te tāpiri i ngā rauemi haurua-ā-ira e aro ana ki te hihi (pērā i te hauhā titanium), e whakaputa ana i ngā rauropi kore utu tino waikura i raro i te hihi mārama, ka pirau katoa ngā poke hei matū kore kino pērā i te hauhā waro me te wai. He nui te kaha o tēnei tikanga ki te rongoā i ngā poke uaua.
