Viemäribakteeritoiminta refers to the biological processes occurring within sewage treatment systems, primarily driven by microorganisms. These bacteria and other microbes play a crucial role in breaking down organic pollutants present in wastewater. This natural decomposition process is fundamental to the purification of sewage before it is discharged back into the environment.

The bacteria in sewage treatment plants utilize the organic compounds in wastewater as a source of energy and nutrients. Different types of bacteria are involved in various stages of the treatment process. Aerobic bacteria, which require oxygen, are prevalent in activated sludge processes where air is supplied to the wastewater. They efficiently convert complex organic molecules into simpler substances like carbon dioxide, water, and mineral salts. Anaerobic bacteria, on the other hand, operate in oxygen-deprived environments, such as in sludge digesters. They break down organic matter into biogas, primarily methane and carbon dioxide, and stabilized sludge.

Understanding and controlling viemäribakteeritoiminta is essential for effective wastewater treatment. Factors like temperature, pH, and the availability of nutrients and oxygen significantly influence the efficiency of these microbial communities. Optimizing these conditions ensures the maximum removal of pollutants and the production of treated effluent that meets environmental standards. The process also generates biosolids, which can be further processed and utilized, for example, as fertilizer.
