The adjective clarifier refers to what clarifies: that is brightens, brightens or cleans something. The term is often used as a noun to refer to a device that removes solid elements from a liquid.
A clarifier, in this framework, is a tank that resorts to mechanical procedures to remove solid. Impurities can float on the surface of the liquid or settle to the bottom.
Clarifiers are used in the treatment of waters. It is usual that, as a process prior to the access of the water to the tank, reagents that favor the flocculation (forming larger and thicker particles) and the coagulation (solidifying). This way, once the water is in the clarifier, it is easier to separate the solids.
It is common for the clarifier to have scrapers or conveyor belts to remove the solids that accumulate. These mechanical parts are constantly moving at a certain velocity.
To treat sewage water, for example, clarifiers are often used to remove the foam by flotation and solids by sedimentation. In addition, the mud particles (that is, those that settle to the bottom) are thickened in them so that it is possible to remove them and then treat them separately.
Also called clarifier is chemical compound that is poured into swimming pools in order to reduce the turbidity level of the water. What the clarifier does is promote flocculation and decantation to help the water remain crystalline with the action of the filter or through a cleaner.
The pool clarifiers, in short, promote an agglomeration of the particles that were suspended, which end up in the background. This way they can be easily removed.
