Sewage treatment plants use microorganisms to destroy the biological material in sewage.
Sewage treatment plants use microorganisms to destroy the biological material in sewage.
If microorganisms are used in the water treatment plant then it is necessary to provide oxygen to them and make the sludge degradation through them so air is bubbled for oxidation as well as for microorganisms.

Sewage purification in natural way:Sewage is purified by microorganisms present in sewage in an environmentally favourable condition to them. Microorganisms purify sewage either in the presence of oxygen or in the absence of oxygen also. When dissolved oxygen is completely utilised resulting no dissolved oxygen in the sewage, sewage attains a stingy condition commonly known as septic condition.
In a sewage treatment process, microorganisms break down organic matter present in the sewage through respiration. As they respire, they release carbon dioxide as a byproduct. This carbon dioxide is formed when the organic compounds in the sewage are broken down and their carbon content is released into the environment as CO2.
Flagellates are found in fresh water as well as in salt water, sewage, and stagnant water.
Protozoa.
In sewage treatment plants, decay and microorganisms break down organic matter in sewage into simpler substances like water, carbon dioxide, and minerals. Microorganisms such as bacteria and fungi play a crucial role in this process by feeding on organic waste and converting it into harmless byproducts through a series of biochemical reactions. These byproducts can then be safely released back into the environment or reused for other purposes.
Many microorganisms are found naturally in fresh and saltwater.
A pollutant, such as fertilizer runoff or untreated sewage, can carry nitrogen compounds and harmful microorganisms into the water supply, impacting water quality and ecosystem health.
The activated sludge process is commonly used to treat sewage. In this process, microorganisms are added to break down organic matter in the sewage, forming a sludge that settles out, leaving cleaner water behind. The cleaned water is then further treated before being discharged.
