Ngā Pūnaha Wai Para WWTP Whakamārama Ngā Kaiwhakarato Maimoatanga Wai Ngā Wāhanga DAF Te Whakarewatanga o te Hau
DAFte rere o te hau rewaKei roto ko te tāke whakatārewatanga, te pūnaha hau rewa, te paipa reflux, te pūnaha hau rewa kua tukuna, te skimmer (I runga i ngā hiahia o te kiritaki, he momo whakakotahi, he momo haereere me te momo mekameka-pereti hei whiriwhiri.), te kāpata hiko me ētahi atu.
Hangarau wehewehenga rangi o Benenv DAFte rere o te hau rewaka whakarewa i te hau ki roto i te wai i runga i tētahi pēhanga mahi. I roto i te tukanga, ka whakakīia te wai pēhanga ki te hau rewa, ka tukuna ki roto i tētahi oko mānu. Ka piri ngā mirumiru hau moroiti i hangaia e te hau kua tukuna ki ngā totoka kua whakatārewatia, ka mānu ki runga i te mata, ka hanga he paraikete paru. Ka tangohia e te koko te paru matotoru. Hei whakamutunga, ka tino purea te wai.
He mea nui te hangarau whakapūmau hau o te whakapūmau hau rewa DAF ki te wehenga totoka-wai (Whakaitihia te COD, te BOD, te chroma, me ētahi atu i te wā kotahi). Tuatahi, whakaranua te matū whakapūmau ki te wai mata, ka whakaohokia kia pai. Whai muri i te wā pupuri whai hua (ka whakatauhia e te taiwhanga te wā, te horopeta me te pānga whakapūmau), ka uru te wai mata ki te rohe whakapā ka piri ngā mirumiru hau moroiti ki te whakapūmau, kātahi ka rere ki te rohe wehenga. I raro i ngā pānga pōturi, ka whakapūmauhia ngā whakapūmau e ngā mirumiru iti ki te mata, ka hanga he paraikete paru. Ka tangohia e te taputapu mimiti te paru ki roto i te ipu paru. Kātahi ka rere te wai kua mārama ki raro ki te puna wai ma mā te paipa kohikohi. Ka hangarua ētahi o te wai ki te tāke whakapūmau mō te pūnaha whakapūmau hau, ko ētahi ka tukuna.
