If the particles are about 4/zm in diameter, the sedimentation flocculation can be 10 times greater than the Brownian flocculation. For particles of about 2/zm in diameter interacting with particles I/zm in diameter, the Brownian flocculation and sedimentation flocculation will be about the same.Energetics of nanocrystalline TiO2 - …,The anatase–rutile transformation depends on impurities, grain size, reaction atmosphere, and synthesis conditions . Zhang and Banfield reported that the anatase–rutile phase transformation occurred at higher temperature with the addition of Al 2 O 3. They attributed this to suppression of coarsening caused by surface diffusion.

One option is to use controlled flocculation. Controlled flocculating additives incorporate the different pigments together in the flocculate and therefore forcibly adjust their mobility. The targeted co-flocculation of the different pigment types therefore combats separation.water treatment - flocculation with sludge …,Scope of flocculation with sludge contact: carbonate removal, iron or manganese removal, clarification as part of pre or post treatment in aerobic or，Remove Iron From Kaolin Using Selective …,Iron and titanium occur as ilmenite and anatase， Method of rapid differential flocculation， remove iron from kaolin using selective flocculation,，Drinking Water Treatment: Coagulation, Flocculation, …,differential sedimentation only occurs between a large and small particle, but fluid shear collisions can occur between any size particles. For this reason, fluid shear is the primary mechanism of floc formation, making the mechanical mixing of …Differential adhesion of Streptococcus gordonii …,Read "Differential adhesion of Streptococcus gordonii to anatase and rutile titanium dioxide surfaces with and without functionalization with chlorhexidine，
