Bridging Flocculation by Polymers - J-STAGE

Bridging Flocculation by Polymers - J-STAGE

where k B is Boltzmann’s constant, T is absolute temperature, μ is the liquid viscosity, d s and d p are, respectively, the solid particle and effective polymer molecule diameters and Ḡ is the mean shear rate due to agitation of the suspension.. For soluble polymers, adsorption will be limited by surface coverage as surface sites become blocked by adsorbed molecules.
