One of the most important global issues today that both wealthy and developing nations, must deal with is wastewater management. One of the main causes of water contamination is the enormous production of industrial effluent, as a result of rapid industrialisation.
Additionally, there are strict laws in place for treating sewage and industrial effluent that is released into the environment. Consequently, it's crucial to have a successful industrial wastewater treatment plant.Utilizing microorganisms for effective and sustainable biological wastewater treatment, has drawn a lot of attention in recent years. However, it has drawbacks, such as the inability to effectively remove some specific pollutants.
Therefore, in order to get over these restrictions, bio-augmentation has proven to be a useful technique that can boost microorganisms' capacity for degradation, while also improving the effectiveness of biological treatment as a whole.
What is biological enhancement or bioaugmentation?
The technique of adding particular supplemental microorganisms to the wastewater treatment system, in order to increase the effectiveness of pollutant degradation in an activated sludge process, is known as bio-augmentation. It aids in the breakdown and removal of contaminants, such as resistant chemicals, in the setting of industrial wastewater systems.
Why is bioaugmentation important?
1: In general, industrial wastewater discharge contains a wide variety of naturally occurring bacterial species. Assuming a steady-state, they gradually gain the ability to handle the degradation of pollutants, over time.
2: Some pollutants can withstand biological breakdown, nevertheless, because of characteristics including high toxicity, low water solubility, and complicated chemical structures. They must therefore be biodegraded by a variety of bacteria. Here, bio-augmentation is useful.
3: Bio-augmentation products use a variety of isolated strains of bacteria and fungi, to gradually change the microbial population. Thus, excessive COD/BOD levels brought on by particular and dominant contaminants in the treatment system, can be addressed by bio-augmentation.
4: It's also vital to keep in mind that industrial wastewater treatment facilities, typically don't run at steady-state settings. The steady-state is impacted by a number of variables, including fast urbanization, a mixing of hazardous and resistant chemicals, and daily changes in influent characteristics. In order to increase the efficiency of operations, like the activated sludge process, additional microorganisms with specialized abilities are used in the bio-augmentation process.
Factors to consider in the bio-augmentation process
1)Strain selection: This is essential to the success of bio-augmentation since chosen strains must be resilient, to all microbial stresses and effluent characteristics. Applications include the use of either a single strain when it is necessary to degrade a particular substance, or a group of strains to recreate a natural community with numerous paths of degradation.
2) Operational Factors: A thorough understanding of all wastewater effluent characteristics and operational parameters is necessary, for the application to be successful. It would be useful to comprehend potential difficulties for the microbial community, such as toxicity and nutrition availability.
3) Dosage site, size, and regime: The dosing site should be chosen after carefully examining the environmental requirements, for the chosen strains. The initial inoculum must be large enough to handle system demands, without disrupting the natural environment hence, dosage quantity and regimen are crucial.
After the initial dose, maintenance treatments could be necessary to keep the populations of the inoculated strains from declining, due to sludge waste.
Advantages of bioaugmentation
1) Increasing the effectiveness of solid settling
It helps in reducing the need for polymers in the settling process by introducing organisms, recognised for their superior floc-forming capacity, and high toxicity resistance to systems.
2) Specific compound degradation
The addition of selective microorganisms to target particular compounds, such as phenols and chlorinated aromatics, can help in breaking down local microbial populations.
3) Improved Nitrification
By adding nitrifying bacteria on a regular basis, it is possible to maintain high levels of ammonia elimination.
The removal of contaminants from wastewater via bio-augmentation is an approach with a high potential. The environmentally friendly method portends well, for wastewater treatment in the future.
