Common Microorganisms Used In Wastewater Treatment

 Wastewater can cause damage to the environment if left untreated. This is because human and pet waste is a source of several types of waterborne disease and bacterial contamination.

 

Thanks in part to microorganisms, it is possible to treat wastewater and sewage. The role of microorganisms in wastewater treatment helps to treat and purify wastewater so that it is less harmful to the environment.

 

While there are many different microorganisms used in wastewater treatment, there are three well-known microorganisms that play an important role in keeping wastewater clean. Each of these types of bacteria helps the treatment process in a unique way, ensuring that there is little impact on the surrounding environment.

 

Common microorganisms used in wastewater treatment

Here is a list of bacteria used in wastewater treatment that you can refer to

 

Aerobic bacteria

Aerobic bacteria are mostly used in new treatment plants and in so-called aerated environments. This type of bacteria uses the free oxygen in the water to degrade the pollutants in the wastewater and then converts it into energy that can be used for growth and reproduction.

 

In order for this type of bacteria to be used correctly, oxygen must be added mechanically. This will ensure that the bacteria are able to do their job correctly and continue to grow and multiply on their food source.

Anaerobic bacteria

Anaerobic bacteria are used in wastewater treatment as normal. The main role of these bacteria in wastewater treatment is to reduce the volume of sludge and to produce methane gas from it.

 

The great thing about this bacterium and why it is used more frequently than aerobic bacteria is that methane gas can be used as an alternative energy source if cleaned and treated properly. This is a huge benefit considering the already high levels of energy consumption for wastewater treatment.

 

Unlike aerobic bacteria, this type of bacteria is able to obtain enough oxygen from its food source that it does not need to add oxygen to help it do its job. The removal of phosphorus from wastewater is another benefit of anaerobic microorganisms used in wastewater treatment.

 

Cultured

Parthenogenic microorganisms in wastewater treatment are bacteria that can vary between aerobic and anaerobic depending on the environment in which they are found. Please note that these bacteria usually prefer to be in an aerobic state.

Final thoughts on the role of microorganisms in water treatment

 

Many industrial and municipal wastewater treatment plants use bacteria and other microorganisms to help in the process of cleaning wastewater. Picking the right bacteria can be tricky as your choice depends on the conditions of effective use in your area. Sewage treatment can also provide a good alternative source of energy if anaerobic bacteria are treated properly.
