Surface finish refers to the process of altering a metal’s surface that involves removing, adding, or reshaping. It is a measure of the complete texture of a product’s surface that is defined by three characteristics of surface roughness, waviness, and lay. The surface roughness is the measure of the total spaced irregularities on the surface.

Filtration is a process that removes particles from suspension in water. Removal takes place by a number of mechanisms that include straining, flocculation, sedimentation and surface capture. Filters can be categorised by the main method of capture, i.e. exclusion of particles at the surface of the filter media i.e. straining, or deposition within the media i.e. in-depth
