Ngā Tikanga Whaihua mō te Houra Kautika i roto i te Maimoatanga Wai Para – Te Whakatutukitanga ki ngā Ture Utu-iti

Mō ngā tohunga o te umanga matū me ngā kaiwhakahaere maimoatanga wai para, he tino whai hua, he ohanga hoki te houra kautika. Mā tēnei ka taea te whakarerekē tere i te pH, te whakatōtō konganuku taumaha, me te whakanui ake i te totohu-totoka. Heoi, ko ngā raruraru noa ko te inenga hē (kāore i te rawaka, i te nui rawa rānei) me ngā tikanga whakarewa hē e arahi ana ki te tauhohenga piri, kāore rānei i oti. Ka aro atu ēnei tikanga mahi ki ēnei wero.

Te Whakarite i mua i te Tātaritanga – Ngā Hipanga Matua e Toru

1. Tātaritanga Wai Para: Ine i te pH, te COD, ngā kukū konganuku taumaha, me ētahi atu tawhā e tika ana. Ko te horopeta o te houra tunutunu e hiahiatia ana ka whakawhirinaki ki te waikawa o te wai para me te nui o ngā parahanga. Ka ārai te tātari i te horopeta iti rawa (te kore e tutuki i ngā ture) me te horopeta nui rawa (te utu nui me te parahanga tuarua).
2. Te Kōwhiringa o te Houra Kai: Mō te maimoatanga waipara whānui, he rawaka te parakore o te 96%, 98% rānei. Mō te waipara matū tino tika e hiahia ana ki te kounga teitei o te waipara, ka taea te whakamahi i te parakore o te 99%+, ahakoa he nui ake te utu.
3. Ngā Taputapu Tiaki Whaiaro (PPE): Mauria he karapu rapa, he mōhiti matū, he kākahu tiaki, me te manawa. Kia tika te hauhautanga, ā, kia wātea hoki te wai horoi ohorere.

Tikanga Whakarewa Tika

Whāia te mātāpono "tāpiri puhoi, whakaoho, whakamatao".

• Ipu Whakarewa: Whakamahia ngā ipu kirihou, uku rānei anake. Kaua rawa e whakamahi i ngā ipu whakarewa, nā te mea ka waikura te wairewa kawakore.
• Te Rahinga Wai: Whakamahia he ōwehenga o te 1 wāhanga houra tunutunu ki ngā wāhanga 10–20 o te wai.
• Tikanga: Tāpirihia te houra tunutunu mārire ki te wai, me te whakaoho tonu. Kaua rawa e tāpirihia he wai ki te houra tunutunu, nā te mea ka pā mai he tauhohenga kino, ka tauhiuhi rānei.
• Te Whakahaere i te Wera: Ka tukuna he wera nui i te wā e whakarewahia ana. Tukua kia whakamatao te wairewa ki te pāmahana rūma i mua i te whakamahinga.

Ngā Tikanga Matua – Te Inenga me te Tikanga Tāpiri

• Te Whakatau Inenga: Hei tohutoro whānui, mā te 5–8 karamu o te houra tunutunu mō ia mita pūtoru o te wai para ka piki ake te pH mā te 1 waeine pea. Heoi anō, me whakamātautau tonu i roto i te ipu: tangohia he tauira iti o te wai para, tāpirihia ngā horopeta rerekē o te otinga houra tunutunu, ka ine i te pH ka puta hei whakatau i te horopeta pai rawa atu hei whakatutuki i te pH whainga o te 7–8.
• Ngā Konganuku Taumaha: Mena kei roto i te wai para ngā konganuku taumaha (hei tauira, te parahi, te rino, te mata), me nui ake te horopeta hei hanga i ngā hauwai waikore. Whakatikatikahia te whakamātautau ipu kia rite ki tēnā, ka ine i ngā kukū konganuku toenga.
• Tikanga Tāpiri: Tāpirihia te otinga houra tunutunu kua oti te whakarite mā te āta, kia ōrite hoki ki te tāke maimoatanga i a koe e whakaranu ana. Whai muri i te tāpiritanga, me whakaranu tonu mō te 10–15 meneti, kātahi ka waiho kia tau.

Ngā Tohutohu me ngā Whakatūpato mō te Penapena Utu

• Whakamahia te houra tunutunu parakore 96% mō te nuinga o ngā mahi; kāore e hiahiatia ana te whakamahi i te parakore teitei ake.
• Whakakotahitia ki ngā matū whakapūkara (hei tauira, te polyaluminum chloride, te polyacrylamide) hei whakapai ake i te rere o te wai me te whakaiti i te kai i te houra tunutunu.
• Kaua e tāpirihia te houra tunutunu me ngā matū waikawa (hei tauira, te waikawa hauwaiora, te waikawa whanariki). Mena e hiahiatia ana ngā mea e rua, me tatari kia 1–2 hāora i waenga i ngā tāpiringa.
• Aroturukihia tonutia te pH i te wā e hoatu ana te horopeta, ā, whakarerekētia mēnā e tika ana.
• Whakakorengia te toenga o te houra kautika i mua i te whakakorenga atu kia rite ki ngā ture taiao.
