The dosage of chitosan required for … WebFlocculation is synonymous with agglomeration and coagulation / coalescence. Basically, coagulation is a process of addition of coagulant to destabilize a stabilized charged …
WebJan 1, 2015 · Polymer-bridging flocculation performance using turbulent pipe flow. 1. Introduction. The aggregation of suspended particles is one of the first processes … When polymers chains adsorb to particles loosely, a polymer chain may bridge two particles, and induce bridging forces. This situation is referred to as bridging flocculation. When particle aggregation is solely driven by diffusion, one refers to perikinetic aggregation. Aggregation can be enhanced through … See more Particle agglomeration refers to formation of assemblages in a suspension and represents a mechanism leading to the functional destabilization of colloidal systems. During this process, particles dispersed in the … See more As the aggregation process continues, larger clusters form. The growth occurs mainly through encounters between different clusters, and therefore one refers to cluster-cluster … See more Numerous experimental techniques have been developed to study particle aggregation.
