In this behaviour clay resembles silicic acid and some other members of the so-called “emulsoid” colloids, and it is suggested that the clay particles are protected by such colloids and thus behave as an “emulsoid” and not as a “suspensoid.”. 1. physik. ."

Flocculation and Dispersion in Soils Soils are generally in an aggregated state, which means the individual particles are stuck together to form clumps. Orthokinetic flocculation arises from induced velocity gradients in the liquid. In early stages of development, some are thought to have supported forest vegetation that was later succeeded by grass. Dispersion of clay affects soil physical properties and can result in clay transport with surface runoff or with percolating water moving through soil macropores.

Because of this, the sedimentation step is usually preceded by a chemical process known as coagulation.

II - Volume 11 Issue 4 - Norman M. Comber. (Department of Agriculture, the University of Leeds. 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. This may be done in either static (Fig. Experiment 3 – To Measure the pH of Soil Large, heavy particles settle out readily, but smaller and lighter particles settle very slowly or in some cases do not settle at all. Encyclopedia.com. It is here that primary particles are induced to approach close enough together, make contact and progressively form larger agglomerates, or flocs. 21 Dec. 2020 .

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 the soil environment the calcium cation serves four basic functions that are critical to agricultural production. © 2019 Encyclopedia.com | All rights reserved. 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.
