The secondary stage of treatment gets rid of about 85% of the natural issue in sewage by using the bacteria in it, based on the EPA. The principal secondary treatment procedures Employed in secondary treatment are the trickling filter as well as activated sludge process.
The activated sludge treatment system is made of an aeration tank accompanied by a secondary clarifier. Settled sewage, blended with clean sludge that's recirculated more info in the secondary clarifier, is launched to the aeration tank.

Quite a few metropolitan areas also use filtration in sewage treatment. Once the solids are taken out, the liquid sewage is filtered by way of a compound, commonly sand, via the motion of gravity. This technique gets rid of virtually all microbes, lessens turbidity and colour, gets rid of odors, decreases the amount of iron, and removes most other sound particles that remained within the water.
