coagulation

Physics

The process in which colloidal particles come together irreversibly to form larger masses. Coagulation can be brought about by adding ions to change the ionic strength of the solution and thus destabilize the colloid. Ions with a high charge are particularly effective (e.g. alum, containing Al³⁺, is used in styptics to coagulate blood). Another example of ionic coagulation is in the formation of river deltas, which occurs when colloidal silt particles in rivers are coagulated by ions in sea water. Alum and iron(III) sulphate are also used for coagulation in sewage treatment. Heating is another way of coagulating certain colloids (e.g. boiling an egg coagulates the albumin).

Chemical Engineering

The joining of colloidal particles to form a larger mass of particles. Coagulation occurs when an agent is added to a colloidal solution in which the ions change the ionic strength of the solution, and therefore destabilize the colloid. For example, alum is used to remove proteins in beer and wine which otherwise give cloudiness. Alum and iron (III) sulphate are used as coagulation agents in sewage treatment.
