Cov txheej txheem sib cais cua ntawm Benenv DAF yaj cua flotation yaj cov huab cua rau hauv dej ntawm qee qhov siab ua haujlwm. Hauv cov txheej txheem, cov dej siab tau saturated nrog cov huab cua yaj thiab raug tso tawm mus rau hauv lub nkoj flotation. Cov pa npuas me me uas tsim los ntawm cov cua tso tawm txuas rau cov khoom khov thiab ntab lawv mus rau saum npoo, tsim cov sludge pam. Ib lub scoop tshem tawm cov sludge tuab. Thaum kawg, nws ua kom cov dej huv.

Cov txheej txheem cua flotation ntawm DAF yaj cua flotation ua lub luag haujlwm tseem ceeb hauv kev sib cais cov khoom khov thiab kua (Ua ke txo COD, BOD, chroma, thiab lwm yam). Ua ntej, sib tov cov neeg sawv cev flocculating rau hauv dej nyoos thiab do kom huv si. Tom qab lub sijhawm khaws cia zoo (chaw kuaj txiav txim siab lub sijhawm, koob tshuaj thiab cov nyhuv flocculation), cov dej nyoos nkag mus rau hauv thaj chaw sib cuag uas cov pa me me lo rau ntawm cov floc thiab tom qab ntawd ntws mus rau hauv thaj chaw sib cais. Nyob rau hauv cov teebmeem buoyancy, cov npuas me me ntab cov flocs mus rau saum npoo, tsim cov sludge pam. Lub cuab yeej skimming tshem tawm cov sludge mus rau hauv lub sludge hopper. Tom qab ntawd cov dej ntshiab qis dua ntws mus rau hauv lub pas dej huv los ntawm cov yeeb nkab sau. Ib feem ntawm cov dej raug rov ua dua rau lub tank flotation rau lub kaw lus yaj cua, thaum lwm tus yuav raug tso tawm.
