Hauv kev kho dej, lub luag haujlwm ntawm polyacrylamide flocculants feem ntau yog tshwm sim hauv sedimentation, flotation, thiab sludge dehydration thaum siv rau ntawm qhov chaw.
Thaum siv rau sedimentation los yog flotation, nws yuav tsum tau soj ntsuam qhov siab ntawm lub sedimentation tank (los yog tshem tawm cov teeb meem nyob rau hauv lub flotation tank), cov tshuaj tiv thaiv tus nqi, sedimentation tus nqi (los yog floating tus nqi), thiab effluent clarity.
Thaum siv rau sludge lub cev qhuav dej, nws yuav tsum tau soj ntsuam tsis tsuas yog cov tshuaj tiv thaiv tus nqi thiab effluent clarity, tab sis kuj qhov luaj li cas ntawm cov av nkos, qhov luaj li cas ntawm cov flocculants, thiab cov dej ntsiab lus ntawm cov av nkos. Cov txheej txheem kev sib txawv thiab kev ua haujlwm yuav cuam tshuam rau kev siv thiab ua haujlwm ntawm cov khoom.
