DAFka lana ʻana o ka ea i hoʻoheheʻe ʻiaʻo ia ka pahu flotation, ka ʻōnaehana ea i hoʻoheheʻe ʻia, ka paipu reflux, ka ʻōnaehana hoʻokuʻu ea i hoʻoheheʻe ʻia, ka skimmer (Ma muli o nā pono o ka mea kūʻai aku, aia nā ʻano i hui pū ʻia, ke ʻano huakaʻi a me ke ʻano kaulahao-pā e koho ai.), keʻena uila a pēlā aku.
ʻO ka ʻenehana hoʻokaʻawale lana ea o Benenv DAFka lana ʻana o ka ea i hoʻoheheʻe ʻiaHoʻoheheʻe i ka ea i loko o ka wai ma kekahi kaomi hana. I ke kaʻina hana, ua hoʻopiha ʻia ka wai i hoʻopaʻa ʻia me ka ea i hoʻoheheʻe ʻia a hoʻokuʻu ʻia i loko o kahi ipu lana. Hoʻopili nā pehu ea microscopic i hana ʻia e ka ea i hoʻokuʻu ʻia i nā mea paʻa i hoʻokuʻu ʻia a lana iā lākou i luna, e hana ana i kahi uhi lepo. Hoʻopau kahi scoop i ka lepo mānoanoa. ʻO ka hope, hoʻomaʻemaʻe piha ia i ka wai.
He kuleana koʻikoʻi ka ʻenehana lana ea o ka lana ea i hoʻoheheʻe ʻia ʻo DAF i ka hoʻokaʻawale ʻana i ka wai paʻa (E hōʻemi pū i ka COD, BOD, chroma, a pēlā aku). ʻO ka mea mua, e kāwili i ka mea flocculating i loko o ka wai maka a hoʻoulu maikaʻi. Ma hope o ka manawa paʻa pono (hoʻoholo ka lab i ka manawa, ka nui a me ka hopena flocculation), komo ka wai maka i loko o ka ʻāpana pili kahi e pili ai nā pehu ea microscopic i ka floc a laila kahe i loko o ka ʻāpana hoʻokaʻawale. Ma lalo o nā hopena buoyancy, lana nā pehu liʻiliʻi i nā flocs i luna, e hana ana i kahi uhi sludge. Hoʻoneʻe kahi mea skimming i ka sludge i loko o ka hopper sludge. A laila kahe ka wai i hoʻomaʻemaʻe ʻia i lalo i loko o ka waihona wai maʻemaʻe ma o ka paipu hōʻiliʻili. Hoʻohana hou ʻia kekahi o ka wai i ka pahu flotation no ka ʻōnaehana hoʻoheheʻe ea, aʻo nā mea ʻē aʻe e hoʻokuʻu ʻia.
