This method is termed ultra-flocculation. Degree of flocculation. The rate at which flocculation occurs is principally governed by the frequency of collision of particles but also by the fraction of surface covered by the flocculant. When collision is the result of mechanical or hydro-dynamical agitation it is called orthokinetic flocculation.

Flocculation. Flocculation is the slow mixing process that causes smaller particles to merge into larger particles that settle more easily. The particles are then more easily removed in the sedimentation and filtration process. The process of flocculation is achieved by controlling the rate of impacts between particles as they gain size.

Flocculation involves a combined process of the aggregation and breakage of suspended particulate matter (SPM) in the water environment, as shown in Fig. 1.Here, aggregation induces particles to attach to each other to form larger flocs, while breakage disaggregates large flocs into smaller flocs or into primary particles (Lee et al., 2012; Maggi, …

Flocculation is a physical process that promotes formation of larger particles by gentle mixing. Alum (an aluminum salt), lime (alkaline chemicals principally containing calcium or magnesium with oxygen), or iron salts are commonly used coagulants. Alum is non-toxic and used in the food industry for pickling.

Flocculation is a key process in water treatment where fine particles suspended in water are brought together into larger clumps called flocs. These flocs are easier to separate from the water, making the treatment process more effective. The formation of flocs is achieved by adding specific chemicals known as flocculants, which help particles bind together.

Flocculation follows coagulation in the conventional water treatment process. During flocculation, a process of gentle mixing causes smaller particles called microfloc to collide and form into larger macrofloc. The speed at which flocculation occurs is directly related to the rate of particle collisions. More mixing energy results in more ...
