 Screening removes large objects such as vegetable matter or sanitary napkins from the water stream in order to avoid clogging the system.  It is usually accomplished using wire mesh screen, bar meshes, rotating drums or other mechanical means, configured for continuous operations.

 Particles are removed by controlling the velocity of the flow and providing impingement surfaces in order to favorise the settlement of particles into the bottom of the cremoval section.

 Equalisers regulate flow in order provide continuous flow to treatment systems and reduce turbulence, favoring settlement.

 Skimmers are used to remove floating grease and oils from the water stream, as these materials are lighter than water and tend to rose to the surface.

+===Primary treatment===
 Primary treatment usually consists of settlement chambers where oils rise to the top and sludge falls to the bottom. The sludge is removed mechanically and transferred to a separate treatment stream.

 Most water treatment systems include a number of steps for waste water treatment.  Screening, filtering, biological treatment and chemical filtration.  Some systems also include Ultra-violet and ozonation.
