WebJan 1, 2014 · 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. During flocculation, gentle mixing accelerates the rate of particle collision, and the destabilized particles are further aggregated and enmeshed into larger precipitates. Flocculation is affected by several parameters, including mixing speeds, mixing intensity, and mixing time. See more Flocculation, in the field of chemistry, is a process by which colloidal particles come out of suspension to sediment under the form of floc or flake, either spontaneously or due to the addition of a clarifying agent. The action differs from See more According to the IUPAC definition, flocculation is "a process of contact and adhesion whereby the particles of a dispersion form larger-size clusters". Flocculation is synonymous with agglomeration and coagulation / coalescence See more Deflocculation is the exact opposite of flocculation, also sometimes known as peptization. Sodium silicate (Na2SiO3) is a typical example. Usually in higher pH ranges in addition to low ionic strength of solutions and domination of monovalent metal See more Surface chemistry In colloid chemistry, flocculation refers to the process by which fine particulates are caused to clump together into a floc. The floc may then float to the top of the liquid (creaming), settle to the bottom of the liquid ( See more • Algaculture – Aquaculture involving the farming of algae • Clay–water interaction – Various progressive interactions between clay minerals and … See more • John Gregory (2006), Particles in water: properties and processes, Taylor & Francis, ISBN 1-58716-085-4 • John C.

WebJul 30, 2024 · From genetic engineering to geoengineering, we treat nature as though it’s a machine. This view of nature has deep roots in Western thought, all the way to Descartes and Hobbs, but it’s a fundamental misconception with potentially disastrous consequences, argues Jeremy Lent. WebJul 15, 2024 · The conversion between flocculated and deflocculated particles was rapid, reversible and highly shear dependent. As such, changing shear rates during laser …
WebWhen clay soils are remoulded, their flocculated structure changes and particles change their orientation from edge-to-face orientation to face-to-face orientation. This kind of formed soil structure is called dispersed soil structure. These soils have relatively lower volume of voids consequently low void ratio.
