Coagulation
Coagulation, also known as clotting, is the process by which blood changes from a liquid to a gel, forming a blood clot. It potentially results in hemostasis, the cessation of blood loss from a damaged vessel, followed by repair.
Filtration
the action or process of filtering something is called filtration.
Sludge
sludge is thick, soft, wet mud or a similar viscous mixture of liquid and solid components, especially the product of an industrial or refining process.
Aeration
the introduction of air into a material is called aeration.
Primary Treatment
Primary treatment consists of temporarily holding the sewage in a quiescent basin where heavy solids can settle to the bottom while oil, grease and lighter solids float to the surface.
Chlorination
chlorination is the process of adding chlorine or chlorine compounds such as sodium hypochlorite to water. This method is used to kill certain bacteria and other microbes in tap water as chlorine is highly toxic.
