Large amounts of wastewater are produced daily from a variety of sources, including houses, businesses, and agricultural operations. It contains hazardous substances, air and water pollutants, and other types of contaminants that might harm local flora and wildlife, as well as the ecosystem.
As a result, wastewater treatment is crucial, and a healthy colony of microorganisms and bacteria is important to this process.
Role of wastewater treatment plants
A wastewater treatment plant's primary objective is to cleanse wastewater to a standard level. Solid particles are removed from the wastewater using physical processes and equipment’s. The wastewater is then cleaned of soluble and insoluble organic material using biological methods.
Bacteria, protozoa, and other types of microbes are primarily responsible for reducing, and purifying the organic matter found in wastewater. Bacteria use substances like lipids, proteins, and sugar as well as nutrients like nitrogen and phosphorus, as a food source.
Microorganisms found in wastewater
There are three different species of bacteria that are typically utilized in a wastewater treatment facility, depending on the availability of oxygen.
· Aerobic bacteria
To work on the waste, aerobic bacteria need a constant supply of enough oxygen. As a result, aeration devices are used to supply oxygen to the treatment tank.
The aeration procedure effectively breaks down the waste, and promotes the growth of bacteria in this environment. It transforms contaminants into energy, which it then uses to expand and flourish.
· Anaerobic bacteria
In the absence of oxygen, anaerobic bacteria are known to decompose organic waste. It doesn't need oxygen separately, because it gets its oxygen from its food source.
The anaerobic bacteria produce by-products like carbon dioxide and water, and are very effective in reducing sludge quantities. It's also possible to generate electricity from the methane gas that is emitted during the process.Additionally, anaerobic bacteria uses the denitrification process to convert nitrate and nitrite, into nitrogen gas.
· Facultative bacteria
Both with and without oxygen, facultative bacteria are able to function. Although, it favours an aerobic environment, it may also endure in other conditions.
What are the Importance of Healthy Bacteria in WWTP?
A balanced bacterial community is necessary for efficient wastewater treatment. However, there are a number of elements that influence the development and functionality of bacteria, in treatment plants. Oxygen consumption, pH, temperature, and dissolved oxygen are all included. While, some of these can be managed, operators are unable to control others.
Furthermore, the performance of bacteria can be impacted by elements, like the climate and the amount of waste produced. This can then result in wastewater treatment facilities failing.
Conclusion
Rapid industry, urbanisation, and population growth result in the production of a significant amount of wastewater. The capacity of the wastewater treatment plant is frequently exceeded. Therefore, to meet these obstacles, creative solutions are needed.
