The difference between mechanical and biological wastewater treatment methods
Wastewater is one of the serious environmental issues that is being addressed and resolved worldwide. Treating wastewater is extremely important to ensure safety for humans, animals, plants, and the environment.
Among them, the method of treating wastewater by mechanical and biological means is widely used due to its effectiveness and environmental friendliness. Let’s learn more about this wastewater treatment method in the following article.

The method of treating industrial wastewater by mechanical means is used to remove insoluble impurities in the wastewater. This is a preliminary stage in the wastewater treatment process and is usually not the final stage. Mechanical methods include screening, sedimentation, hydraulic cyclones, filtration through sand media, and centrifugation.
The mechanical wastewater treatment method is a simple and independent method, requiring few expensive materials and equipment. It can be performed on small or large treatment facilities depending on the level of production.
However, this method has some limitations. Firstly, it only removes insoluble impurities, while soluble impurities in the wastewater will not be removed. Therefore, other methods need to be used to remove soluble impurities. Secondly, the mechanical wastewater treatment method cannot remove organic substances in the wastewater. To remove organic substances, biological or chemical treatment methods need to be employed.
Although there are such limitations, the mechanical wastewater treatment method is still an important method in the wastewater treatment process. Removing non-dissolved impurities such as debris, sand, and other suspended impurities is crucial to ensure the effectiveness of subsequent treatment methods such as biological or chemical treatment.
Moreover, the mechanical wastewater treatment method can also be used to minimize pollution and negative impacts on the environment. When non-dissolved impurities are removed, the wastewater will become cleaner and safer to discharge into the environment.

Industrial wastewater treatment by biological method
The method of biological wastewater treatment is one of the most effective and environmentally friendly technologies today. This method uses microorganisms to decompose pollutants in wastewater, reducing the levels of contaminants such as COD and BOD in the wastewater and meeting the standards for wastewater quality discharged into the environment.
One of the advantages of this method is its stability and cost-effectiveness. Compared to other wastewater treatment methods, the biological method requires fewer materials and equipment and does not require much human intervention. Additionally, this method provides environmental benefits by reducing the impact of wastewater on water resources and minimizing the presence of harmful substances in the environment.
However, this method still has some drawbacks that need to be noted. One of them is the need to control and monitor the strains of microorganisms used to treat wastewater. The microorganisms, such as bacteria, viruses, or algae in wastewater, can carry diseases for humans, so it is essential to ensure the quality of wastewater before releasing it into the environment. Monitoring and controlling the quality of wastewater after treatment is also crucial to ensure safety for the environment and human health.
In summary, the biological wastewater treatment method is one of the most effective and environmentally friendly technologies available today. However, to ensure the safety of the environment and human health, it is necessary to control and monitor the quality of wastewater before and after treatment using this method.
