In a later development, Somasundaran et al. ]57] developed a PBM for aggregation by polymers in shear environments. The D LVO theory was extended for this case, as discussed in the previous section, by using the modifled expression for van der Waals attraction for particles covered with polymers and the expression for bridging attraction or steric repulsion derived from the scaling theory [25]. Their model was tested qualitatively with experimental data for the flocculation of colloidal alumina suspensions in the presence of PAA and was found to reproduce the observed experimental trends [60] reasonably well.
