Nga Pūnaha Waipara WWTP Whakamarama Kaituku Tiaki wai DAF Waeine Rererangi Rererangi
DAFte rere o te hau rewaKei roto i te tank flotation, te punaha hau rewa, te putorino rewharewha, te punaha tuku hau rewa, te skimmer (I runga i nga hiahia o nga kaihoko, he momo whakakotahi, momo haere me te momo mekameka-pereti hei whiriwhiri.), rūnanga hiko me etahi atu.
Hangarau wehewehe rererangi rererangi o Benenv DAFte rere o te hau rewaka memeha hau ki te wai i etahi pehanga mahi.I roto i te tukanga, ka kuhu te wai pehanga ki te hau memeha, ka tukuna ki roto i te waka rererangi.Ko nga mirumiru hau moroiti i puta mai i te hau i tukuna ka piri ki nga totoka iri ka rewa ki te mata, ka hanga he paraikete paru.Ka tangohia e te kokopi te paru kua matotoru.Ka mutu, ka oti te pure i te wai.
Ko te hangarau rererangi o te DAF te whakarewanga o te hau ka whai waahi nui ki te wehenga totoka-wai (I te wa ano ka whakaitihia te COD, BOD, chroma, etc).Ko te tuatahi, uruhia te maatete ki roto i te wai mata, ka tino whakaohokia.Whai muri i te wa pupuri whai hua (ka whakatauhia e te taiwhanga te wa, te inenga me te paanga o te putunga), ka uru te wai mata ki roto i te rohe whakapiri ka piri nga mirumiru hau moroiti ki te floc katahi ka rere ki te rohe wehe.I raro i nga paanga o te pupuhi, ka rewa nga mirumiru ririki i nga kahui ki te mata, ka hanga he paraikete paraikete.Ka tangohia e te taputapu paraka te para ki roto i te kopa para.Katahi ka rere te wai whakamarama o raro ki roto i te putunga wai ma ma te paipa kohi.Ko etahi o te wai ka recycled ki te taika rererangi mo te punaha whakamahana hau, ko etahi ka tukuna.
