Difference Between Flocculation And Deflocculation 2 Systems Theory The magnitude of the repulsive forces at the primary maximum determines whether a flocculated system will remain flocculated. if the thermal energy in the system is similar to, or greater than, the repulsive barrier, the particles in the system can move closer together (0.5 – 2.0 nm) and encounter strong attraction due to the primary minimum. 2.2.7 flocculation and deflocculation. a deflocculated system has a zeta potential higher than the critical value when the repulsive forces supercede the attractive forces. particles in this type of systems remains suspended for a long period of time, and only a small portion of the solid is found in the sediment due to the force of gravitation.
Ppt Suspensi Powerpoint Presentation Id 1843019 Flocculation (except in polymer science) process of contact and adhesion whereby dispersed molecules or particles are held together by weak physical interactions ultimately leading to phase separation by the formation of precipitates of larger than colloidal size. in contrast to aggregation, agglomeration is a reversible process. Knowledge of interfacial properties, wetting, electric double layer, nernst and zeta potential, electrokinetic phenomenon, dlvo theory, flocculation, and deflocculation should ultimately help the formulator select the ingredients that are most appropriate for the suspension as well as formulate suspensions that are physically stable and suitable for administration to patients. A flocculated suspension is a suspension in which particles of the suspension has undergone flocculation. a flocculated suspension is composed of large aggregates (flocks) and this type of suspension will lead to a rapid rate of sedimentation. sedimentation is the settling down of aggregates or particles of suspension to the bottom of the liquid. 6.1 introduction. a disperse system is defined as a two phase system in which an insoluble or immiscible dispersed phase (e.g., solid particles or liquid droplets) is distributed through a continuous phase. disperse systems are typically classified based upon the size of the dispersed phase (i.e., particles or droplets).

Flocculation – process during which particles, for example, of a soil, dispersed in a solution contact and adhere each another, forming clusters, flocks, flakes, or clumps of a larger size. the term originates from the word “floc,” which is the flake of precipitate that comes out of solution. the floc may float to the top or settle to the. Flocculated and deflocculated suspensions represent two different states of particle dispersion within a liquid medium. flocculation refers to the aggregation of particles into loose clusters or flocs, while deflocculation involves the dispersion of particles to a uniform, individual state. these states have distinct characteristics, mechanisms.
