Sedimentation yog ib qho ntawm ob peb txoj kev rau daim ntawv thov ua ntej pom: lwm yam kev xaiv muaj xws li yaj huab cua flotation thiab qee qhov txoj kev ntawm filtration.

Cov piv txwv ntawm sedimentation yog dab tsi?

Rau piv txwv , xuab zeb thiab silt yuav nqa tau nyob rau hauv kev ncua nyob rau hauv dej ntws thiab mus txog lub hiav txwv txaj tso los ntawm sedimentation.
