HLN-127 Ārai Waikura Whakakore mō ngā Wāhanga Whakamakuku Hauātea me te Korehau
Ngā Āhuatanga o te Hua
- Whakahaere pH: Ka pupuri i te pH o te wai whakapūpū i waenga i te 5.5 ki te 6.0, ka whakataurite i te waikura waikawa me te waikura iti i puta mai i te NH4Cl me te FeS.
- Mahi Whai Hua: Ka whakaiti i te whakamahinga o ngā kaihoko mā te neke atu i te 20% ki te whakataurite ki ngā hua ōrite, ka eke ki te tere aukati waikura o te ≥90%.
- Ārai-Whakarewa: Ka whakaiti i te ia o te wai whakapūpū ki te hanga i ngā whakarewa, ka whakaheke i te nui o te hinu me te COD i roto i te wāhanga wai.
- Haumaru ki te Taiao: Kore he konganuku me ngā huānga kino, kia kore ai he pānga kino ki ngā wae tukatuka o raro iho, ki ngā pūnaha maimoatanga wai para rānei.

Ngā tono
- Te Whakahaere Waikura: Ka ārai i te waikura HCl-H2S-H2O i roto i ngā pūnaha whakamatao whakatōtō o runga o ngā waeine whakatōtō hau me te korehau.
- Te Whakaiti i te Tauine: Ka ārai i te tauine o te ammonium chloride (NH4Cl) me te rino sulfide (FeS), ka karo i te waikura tuarua, ā, ka whakarite kia roa te ora o ngā taputapu.
Ngā Tohutohu Whakamahinga
1. **Te Whakarite:** Papuhia te hua ki roto i tētahi tāke rokiroki aukati waikura, ka whakaranua ki te wai kua tangohia ngā kohuke, te wai kua tangohia te hāora rānei ki te kukū e hiahiatia ana.
2. **Ngā Wāhi Werohanga:** Whakamahia he papu ine hei wero i te aukati i mua i te wāhi werohanga wai i te rārangi mimiti i te tihi o te pou whakamātao, ko te mea pai ko te tata ki te pūwāhi tomairangi.
3. **Inenga:** Whakatikatikahia ngā tere werohanga kia mau tonu te pH o te wai whakapūhau i waenga i te 5.5 me te 8.0. Inenga noa: 10-40ppm (e pā ana ki te hinu mata). Ka taea te whakanui ake i ngā inenga tuatahi kia whakatūria he taurite mimiti.
4. **Whakarerekētanga Ritenga:** Whakarerekētia ngā tere werohanga i runga i ngā āhuatanga hinu mata (te ihirangi hauwai me te whanariki waro), ngā taumata katote hauwai konutai, me ngā raraunga aroturuki waikura.
Pūtāhui Mahi
- Ka pupuri i te kukū o te katote rino i roto i te wai whakapūmau i ngā wāhi tino nui (hei tauira, te pourewa whakatō tuatahi, te pourewa āhuarangi, me ngā tihi pourewa korehau) he ≤3mg/L.
- Kāore e whakaemulsification, kāore hoki e pā ki te wehenga hinu-wai, te pumau o te taputapu, te kounga rānei o te hua.
- Kāore he pānga kino ki ngā wae tukatuka o raro iho, ki ngā pūnaha maimoatanga wai para rānei.
- Inenga e Manakohia ana: I runga i ngā āhuatanga o te hinu mata, kei te ripanga e whai ake nei he aratohu mō ngā reiti werohanga whakakāhore.
