Sedimentation Kaolin Flocs

  • Effect of the concentration of NaCl and cylinder

    · The sedimentation behavior of flocs is dependent on floc size which in turn is controlled by salt concentration and collision rate between flocs Our findings suggest that the size of the flocs increases owing to prolonged traveling distance in higher cylinders coupled with the sedimentation turbulence that emerges during the gel collapse
