Kaihoko Huakita Āhuarangi
Whakaahuatanga
He paura mā tēnei, ā, he mea tito mai i ngā huakita me ngā koki, ka taea e ēnei te hanga pua (endospores).
Kei roto neke atu i te 10-20 piriona/karamu o ngā huakita ora
Mara tono
He pai mō te taiao whai hāora o ngā tipu maimoatanga wai para o te tāone, ngā momo wai para matū ahumahi katoa, te wai para tā me te tae, te wai para para, te wai para o te ahumahi kai me ētahi atu maimoatanga wai para o te ahumahi.
Ngā Mahi Matua
1. He pai te mahi a te huakita ki te whakapōrearea i ngā mea rauropi i roto i te wai. Nā te kaha o te ātete o ngā huakita pūrua ki ngā āhuatanga kino o waho. Ka taea e ia te whakanui ake i te kaha o te pūnaha maimoatanga paru ki te ātete i te kawenga pānga, ā, he kaha hoki te kaha ki te whakahaere, ka taea e te pūnaha te whakahaere tika ahakoa te rerekētanga nui o te kukū o te paru, me te whakarite kia pumau te tukunga para.
2. Ka taea e te huakita hauropi te tango i te BOD, te COD me te TTS. Ka whakapai ake i te kaha taunga totoka i roto i te puna whakatō, ka whakanui ake i te maha me te kanorau o ngā protozoa.
3. Tīmata me te Whakaora i te Pūnaha Tere, whakapai ake i te kaha tukatuka me te ātete pānga o te pūnaha, whakaitihia te nui o te paru toenga e puta ana, whakaitihia te whakamahinga o ngā matū pēnei i te flocculant, penapena hiko.
Tikanga Tono
1. E ai ki te taupū kounga wai ki roto i te pūnaha matū koiora o te wai para ahumahi: ko te horopeta tuatahi he tata ki te 80-150 karamu/pūtoru (e ai ki te tātaitanga rōrahi o te puna matū koiora).
2. Mena he nui rawa te pānga ki te pūnaha matū koiora nā te rerekētanga o te wai whāngai, tāpirihia he 30-50 karamu/pūkara ia rā (e ai ki te tātaitanga o te rōrahi o te puna matū koiora).
3. Ko te horopeta o te wai para o te tāone he 50-80 karamu/pūtoru (e ai ki te tātaitanga o te rōrahi o te puna matū koiora).
Whakatakotoranga
E whakaatu ana te whakamātautau ko ngā tawhā ā-tinana me ā-matū e whai ake nei te mea tino whai hua mō te tipu o te huakita:
1. pH: I waenga i te 5.5 me te 9.5, ko te tere o te tipu kei waenga i te 6.6-7.8, ko te pH 7.5 te mea tino pai rawa atu mō te tukatuka.
2. Pāmahana: ka pā mai i waenganui i te 8℃-60℃. Ka mate ngā huakita mēnā he teitei ake te pāmahana i te 60℃. Mēnā he iti iho i te 8℃, e kore e mate, engari ka tino āraihia te tipu o ngā huakita. Ko te pāmahana tino pai ko te 26-32℃.
3. Hāora Rewa: Ko te hāora rewa i roto i te tāke whakapūngao o te maimoatanga wai para he 2 mg/l te iti rawa; ka tere ake te pākia me te tere o te pirau o ngā huakita pakari ki te matū ūnga mā te 5~7 ngā wā me te nui o te hāora.
4. Ngā Huānga Āhuahira: Ka hiahiatia e te rōpū huakita motuhake he maha ngā huānga i roto i tōna tipu, pērā i te pāhare pāporo, te rino, te whanariki, te konupora, me ētahi atu. I te nuinga o te wā, he nui ngā huānga kei roto i te oneone me te wai.
5. Te tote: E tika ana mō te wai tote me te wai māori, ko te manawanui mōrahi ki te tote he 6%.
6. Ātete Paitini: Ka taea e ia te ātete pai ake i ngā matū paitini, tae atu ki te hauota, te cyanide me ngā konganuku taumaha, me ētahi atu.
