In dispersed clay slurries, flocculation occurs after mechanical agitation ceases and the dispersed clay platelets spontaneously form flocs because of attractions between negative face charges and positive edge charges.
(2) Dispersion (or disaggregation) causes clay platelets to break apart and disperse into the water due to the loss of attractive forces as water moves the platelets further apart. (3) Flocculation begins when mechanical shearing stops, and platelets previously dispersed come together due to the attractive force of surface charges on the platelets.
A well dispersed colloidal suspension consists of individual, separated particles and is stabilized by repulsive inter-particle forces. When the repulsive forces weaken or become attractive through the addition of a coagulant, particles start to aggregate. Initially, particle doublets A 2 will form from singlets A 1 according to the scheme [2]
The formation of soil aggregates (or so-called secondary soil particles or peds) occurs due to interactions of primary soil particles (i.e., clay) through rearrangement, flocculation and cementation. Aggregate stability has a direct impact on soil pore size distribution, which affects soil water retention and water movement in soil, therefore ...
The use of depletion forces to initiate flocculation is a common process in water treatment. The relatively small size of dispersed particles in waste water renders typical filtration methods ineffective. However, if the dispersion was to be destabilized and flocculation occur, particles
Flocculation is the accumulation of drops within a continuous liquid phase. Creaming is the accumulation of drops at the top of a liquid continuous phase. Coalescence is the merging of two drops into one single drop. Demulsification is when the dispersed phase completely coalesces into one continuous phase.
If these fine particles remain dispersed in the water column, Stokes law applies to the settling velocity of the individual grains, [4] although due to seawater being a strong electrolyte bonding agent, flocculation occurs where individual particles create an electrical bond adhering each other together to form flocs. [4] "The face of a clay ...
Once the clay is deposited on the ocean floor it can change its structure through a process known as flocculation, process by which fine particulates are caused to clump together or floc. These can be either edge to edge flocculation or edge to face flocculation. Relating to individual clay particles interacting with each other.
