We will start the discussion here with the basics so, therefore, we will, first of all, see the definition of sewage, to define sewage in simple words we can say that sewage is actually the waste that is produced by humans as part of their digestion process. It is very much essential to get this sewage treated as if the sewage will be left untreated then that would further lead to many infections and other life-threatening diseases. Now let us further move the discussion regarding the sewage treatment system in India, if we talk regarding the system in general then we can say that it is all handled by the public treatment works that are facilitated by the city, country, or the region based systems, it all depends on the funding and building of the system as it comes to the operations of the systems. In further discussion regarding the sewage treatment system, we can say that these systems work by separating the solids from the waste. After the separation of the solids from the waste, the leftover is then put for treatment.


If we further talk regarding the importance of the sewage treatment system in detail then we can say that it is not just regarding the maintenance of health, hygiene, and cleanliness it is also regarding the importance of the sludge that is produced as a result of the sewage treatment. This sludge can be taken into use as the fertilizer and the sewage sludge is always counted as the most efficient source for the fertilization of the soil. There are chemical fertilizers also available but the sewage sludge is always preferred more for being a natural source of fertilizing the soil.


But here it is not regarding the general discussion of the sewage treatment or the sewage treatment system; here the discussion is to be focused on the biological sewage treatment system here we will define the biological sewage treatment system along with its workings.


Defining the biological sewage treatment system we can say that this sewage system is actually a small part of the bigger sewage treatment process we can also say that through the biological sewage treatment system the process of sewage treatment is conducted through the biological natural bacteria. It is through the bacteria that all the waste is broken down into by-products such as sludge.


Further talking regarding the working procedure of the biological sewage treatment system we can say that all the untreated sewage wastewater is collected from all over the city, goes into the sewers, and further enters into the pump stations, and finally reaches to the plants. After that in the reactor basins, the water is treated with the help of the microorganisms. The water after this process flows through another clarifier and the biosolids are separated and the microorganisms are retained. The microorganisms are then settled at the bottom in a cone-shaped base and from there they are returned back as activated sludge. Making it simpler we can say that the untreated wastewater is combined with the bacteria and thus the bacteria is allowed to grow. We can further divide the workings of a biological sewage treatment system into simple points so that it would become clearer in the heads of the people: The organisms are grown in a suspension and are retained. The wastewater is mixed with the biomass. The mixed liquor is aerated and thus the bacterium gets to work. The mixed liquor suspended solids are further settled. The activated sludge is sent to the reactor basin. Waste activated sludge is sent for further dewatering and treatment. If one would get more into details regarding the biological sewage treatment system then we can say that there are various sewage treatment system variations that are there in the market. One can select anyone out of them considering all the factors that are associated with the process of sewage treatment and the requirements that are associated with the sewage treatment. Also, the choice of the sewage treatment system may depend on budget and other things such as the geography of the place where the sewage treatment system is to be taken into use. So reading this carefully is going to help all those who are planning to get a sewage system installed specially a biological sewage treatment system.
