I te Hakihea, 2021, kua oti te whakahau i te rere o te rangi kua rewa ka tutuki ki te paerewa wheketere kia pai ai te tuku.
Ko te Whakarererangi Hau ( DAF System) he tukanga maimoatanga wai e whakamarama ana i te wai para (tetahi atu wai ranei, penei i te awa, i te roto ranei) ma te tango i nga totoka susu, te hinu me te hinu.Ka whakamahia nuitia i roto i te maimoatanga wai para mo te wehenga totoka-wai, ka taea e ia te tango i nga totoka iri, te hinu me te hinu me te matū colloidal.I tenei wa, ka taea te whakaiti i te COD, BOD.Koia te taputapu matua mo te maimoatanga wai para.
Ngā Āhuatanga Hanganga
Ko te Pūnaha DAF te nuinga o te papu hau rewa, te hau compressor, te ipu hau rewa, te tinana taika maitai tapawhā, te punaha skimmer.
1. Mahi ngawari me te whakahaere ngawari, he pai te whakahaere i te nui o te wai para me te kounga.
2.Ko nga mirumiru moroiti e hangaia ana e te ipu hau kua memeha he 15-30um noa iho, he kaha te piri ki te flocculant kia pai ake ai te painga o te rere.
3. Pūnaha hau rewa GFA ahurei, te tino pai o te hau memeha ka tae ki te 90%+, te kaha kaha mo te aukati
4. He momo pereti mekameka, he mahi pumau me te tino pai ki te pakaru.
Kaupapa Mahi
Ko te wai hau memeha e whakaputahia ana e te punaha GFA ka panaia ki roto i te tuku hau ma te whakaiti i te pehanga.15-30um nga mirumiru moroiti mai i te kaiwhakaputa hau ka piri ki nga totoka iri ka mama ake i te wai, katahi ka rewa nga totoka me nga mirumiru moroiti ki runga ki te mata hei hanga i te paparanga paru ka tangohia e te punaha skimmer ki roto i te tank para. .Ka rere te wai ma o raro ki te taika wai ma.Neke atu i te 30% o te wai ma ka hangarua mo te punaha GFA ka tukuna etahi atu, ka maemaa ranei ki te mahi ka whai ake.
Taupānga
Ko te Pūnaha DAF, hei mahi maimoatanga wai parakore, e whakamahia nuitia ana i roto i te miihini horoi parapara.Ka taea te whakamahi mo enei ahumahi:
1. Ahumahi pepa — hangarua te penupenu ki te wai ma me te wai ma i hangarua hei whakamahi.
2. Ahumahi kakano, ta me te tae tae - te whakaheke i te chromaticity tae me te tango SS
3. Whare patu me te ahumahi kai
4. Te ahumahi Petro-matū - te wehenga hinu-wai
