What is the size of bacteria or microorganisms founds in STP Plant?
Sewage treatment plants play a crucial role in the removal of pollutants and contaminants from wastewater. The treatment process involves the use of various biological, physical, and chemical processes, and bacteria play a significant role in the process.
In this blog, we will discuss the size and appearance of bacteria found in sewage treatment plants and the quantity of bacteria that may be found per liter of sewage water.
Size and Appearance of Bacteria in Sewage Treatment Plants
Bacteria are microscopic organisms that are too small to be seen with the naked eye. The size of bacteria varies depending on the species, and most bacteria found in sewage treatment plants range from 0.5 to 5 microns in diameter and 1 to 10 microns in length. Bacteria have various shapes, including spherical (cocci), rod-shaped (bacilli), and spiral-shaped (spirilla). The shape and size of the bacteria play a significant role in the treatment process, as different bacteria are responsible for different stages of the process.
The appearance of bacteria can be observed under a microscope. In sewage treatment plants, bacteria are usually present in the form of flocs or clumps. Flocs are aggregates of bacteria and other microorganisms that are held together by extracellular polymeric substances (EPS). The flocs play a critical role in the treatment process, as they help in the settling of the solids and the removal of pollutants.
Quantity of Bacteria in Sewage Water
The quantity of bacteria present in sewage water varies depending on the source of the water and the treatment process. In raw sewage water, the quantity of bacteria may range from 10^6 to 10^9 bacteria per liter. However, during the treatment process, the number of bacteria is reduced significantly. The final effluent from the treatment plant may contain as few as 10^3 to 10^5 bacteria per liter.
The quantity of bacteria present in sewage water is critical for the treatment process. The bacteria play a significant role in the biological processes that occur during the treatment process. The bacteria break down organic matter and convert it into less harmful substances. The quantity of bacteria is monitored regularly during the treatment process to ensure that the treatment process is working efficiently.
Conclusion
In conclusion, bacteria play a crucial role in the treatment of sewage water. The size and appearance of bacteria found in sewage treatment plants vary depending on the species and stage of the treatment process. Bacteria are present in the form of flocs, which help in the settling of solids and the removal of pollutants. The quantity of bacteria present in sewage water varies depending on the source of the water and the treatment process. The quantity of bacteria is monitored regularly during the treatment process to ensure that the treatment process is working efficiently. Overall, bacteria are a vital component of the sewage treatment process, and their presence is essential for the removal of pollutants and contaminants from wastewater.
