Fine silt soils are not flocculated by calcium hydroxide on account of the inefficiency of the relatively small amount of “emulsoid” clay to protect the large “suspensoid” surface exposed by the fine silt. Flocculation is thus the initial step leading to further aging of the emulsion (droplet coalescence and the ultimate separation of the phases).

Williamson, William Turner Horace The effect of soil: solution ratio on clay dispersion was attributed to greater shattering and abrasive action of soil aggregates against each other as their concentration in suspension increased. Most of the soils have gentle slopes and are used as cropland. Flocculation, in physical chemistry, separation of solid particles from a liquid to form loose aggregations or soft flakes. In the context of heavy oil, asphaltenes are known to flocculate at the molecular level (before precipitation) and in the precipitated state.The extent of asphaltene flocculation changes with fluid composition, temperature and pressure.For precipitated asphaltenes, flocculation is also affected by the shear environment. In agricultural soils the calcium cation flocculates clay and organic matter particles which results in proper soil porosity. Flocculation is destroyed by long periods of drought and by washing away the magnetism in the soil. CRTSL0101612. This may be done in either static (Fig. Filter the soil solution into a test tube through filter paper. A calcium-dominated soil is granular in structure and porous.

A Dictionary of Nursing. flocculation A process in which clay and other soil particles adhere to form larger groupings or aggregates, thereby coarsening the soil texture and making heavier soils easier to cultivate. In industrial processes, flocculation may be a desired or an undesirable phenomenon, and various methods may be used to cause or eliminate flocculates. The principal parameter governing the rate of orthokinetic flocculation is the velocity gradient applied. Page 425 note 1 Pickering has advanced a different explanation.

So the process is more complex than simple Creaming. flocculation behaviors of soil clays were studied at different Ca:Mg ratios and solution electrolyte.

The view is advanced and some experimental support of it is described, that clay, as an “emulsoid,” protects the larger particles which by themselves are “suspensoid.” The soil aggregates are conceived as having large nuclei surrounded by particles which become smaller from the centre of the aggregate outwards, the clay ultimately imposing its “emulsoid” nature on the whole aggregate, and on the whole soil in normal cases.
