Biological wastewater treatment using biological filters has been used for a long time. It has a lot of advantages. In this essay, I discuss the two main types of biological filters and provide some details on the design of a relatively new type of one of them. see this Advanced Bio-Treatment

Biological filters are used to treat wastewater biologically by exposing them to wastewater and air alternately. This permits the microorganisms to multiply and build a layer on the surface of the biological filter. The bacteria that live in this stratum break down the wastewater’s contents. These microbes adsorb the organic particles in the wastewater and breakdown them through an aerobic process. These biological filters can be categorised into two groups. The spinning biological reactor and the fixed media filters are the two groups. Both of these groupings share the ability to produce a microbial film.

The Biotower is a relatively new form of fixed media filter. This is made up of plastic waffles placed in a honeycomb pattern. This is where the microbe film forms, which aids in the biological treatment of wastewater. This kit includes a growing media that aids in the growth of a commercially available bacterium culture. A nutrient solution containing a mixture of ammonia and phosphorus is also provided for bacterial development. At the bottom of the Biotower, the bacterial culture, influent wastewater, and fertiliser solution are all introduced and combined. With the help of a forceful draught of air, this combination is subsequently propelled upwards. The treated wastewater emerges from the Biotower’s top section.
