TLDR
Comparison of the two polymeric flocculants revealed that both the fractal dimension and the tendency for ruptured fragments to reflocculate were sensitive to the polymer used.About:

A review of floc strength and breakage.
TL;DR: Current theoretical understanding of floc growth and breakage and an analysis of different techniques used for measuring floc strength are reviewed, with general trends emerge showing that smaller flocs tend to have greater strength than largerflocs, whilst the use of polymer seems to give increased strength to only some types offloc.

Nanoparticles: structure, properties, preparation and behaviour in environmental media
TL;DR: The key properties of nanoparticles and their preparation are discussed and how these factors can play a role in determining their fate and behaviour in the natural environment are discussed.

Aggregation and disaggregation of iron oxide nanoparticles: Influence of particle concentration, pH and natural organic matter.
TL;DR: The formation of small aggregates of about 170 nm and surface coating of several nanometers of SRHA on iron oxide NPs confirm the role of NOM in the disaggregation process and indicate that NPs might mimic the behavior of natural colloids.

Flocculation modelling : A review
TL;DR: In this article, a review of recent developments in this area is discussed with reference to the classical analytical expression of Smoluchowski defining collision frequency and originally published in 1917, with the key models that have been developed to address specific limitations discussed in detail.
