Nyob rau hauv cov txheej txheem aeration, ib lub taub hau aeration, uas yog, yuav tsum tau muaj cov dej khib nyiab diffuser. Cov dej khib nyiab diffuser ze tshaj rau cov qauv siv hluav taws xob no yog hydraulic shearing hom diffusion ntaus ntawv-ib qho inverted basin hom khib nyiab diffuser. Nws muaj lub tswb-puab lub plhaub nrog cov cua nkag thiab lub phaj roj hmab. , Ntsia hlau thiab txiv ntseej.
Cov ntug sab saud ntawm cov dej khib nyiab inverted diffuser yog ua los ntawm polyethylene yas, thiab ib lub phaj roj hmab txhawb nqa hauv qab nws. Thaum lub sij hawm aeration, cov cua tshuab tawm los ntawm ib ncig ntawm cov roj hmab phaj thiab tig thiab nce nyob rau hauv ib tug dav dav dav ntws. Cov nyhuv shearing thiab turbulence tshwm sim los ntawm lub swirling flow Cov nyhuv ntws ua rau cov npuas me me, cov kua zaj duab xis yog rov ua dua sai dua, thiab cov nyhuv zoo dua. Qhov tsis zoo yog tias nws tsis tuaj yeem muab cov npuas me me nrog kev hloov pauv siab dua.
