… If a floc density slightly greater than 1 (ie 1.05 g/mL) is assumed with an average floc diameter
of 20 μm, the expected floc … (This floc number estimate is rather insensitive to the precise …

… roundness of the floc 30 and reduce its shape factor. The most important factors contributing
to the high settling velocities of ballasted flocs seem to be the increased floc density. Zhu 31 …

… for water treatment, the increase in flocculation time above 40 min. shows impairment of floc
… The purpose of flocculation is to create a floc of a suitable size, density, and toughness for …

… of flocs (number/milliliter); and pp = density of primary particles (grams/centimeter cubed).
6. The modified density (Pro) is calculated by: 9m = 9p - (gp - 1)fm. This flOC density is used in …
