ʻO ka ʻenehana hoʻokaʻawale lana ea o ka lana ea hoʻoheheʻe ʻia ʻo Benenv DAF e hoʻoheheʻe i ka ea i loko o ka wai ma kekahi kaomi hana.

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.
