Human activities produce a huge volume of sewage and wastewater that needs to be treated before it is safe to be discharged into waterways. Mostly wastewater has excessive amounts of minerals such as nitrogen, phosphorus and other metallic compounds. In addition, it also has organic pollutants that could cause pollution of waterways as well as other non-biodegradable and pathogenic microorganisms that can lead to infections. Microbial treatment of wastewater is very important for the organic wastes.
Considering these high levels of toxins, proper treatment is crucial before any waste is to be allowed to reach the environment. There are chemical and biological wastes that must be broken down or eliminated to normal safe levels present in clean water. There are many processes that are used in different places for the degradation of both organic and inorganic products. One popularly used method is the use of microbes to degrade organic matter. Once treatment is over purification becomes the final process to clean and safe drinking water.
The use of microbes in treatment plants has been well studied and it forms an important part in the purification process. However a challenge arises when the number of these organisms reduces or is completely eliminated. This could occur following many different reasons that affect the microbial population. This then leads to organic material building up. In these cases it becomes necessary to supplement microbial agents. It can be done at several stages.
In the general the cleaning process, there are three steps under which the wastewater undergoes. The primary stage is responsible for removing any heavy matter that is contained through allowing it to settle at the bottom. The lighter material at the top can also be easily removed because it remains floating. A secondary step is to remove any biological mater present in the water while the tertiary stage involves any other process to enhance water safety.
The use of microbes to degrade organic waste is primarily a secondary stage process. These organisms break down organic matter by feeding on material as a source of their food. An increase in the number of the microbes like through supplementation can enhance the process while a low number can cause accumulation of waste.
The use of microbes is not only limited the second stage of processing. Introducing them from the start of the purification allows them to begin the degradation process earlier. The result is increase breakdown of any waste present and a more efficient process.
In some cleaning plants, there are additional stages that have been added where the waste in water is suspected to have a higher organic content. These microbes are therefore used in the tertiary steps to further eliminate the waste. This is important because of harmful downstream problems of high levels of organic matter. The use of microorganisms could be substituted with using chemicals at this step to try maintaining the process natural and pollution free.
The sludge produced in the primary stage has also to be disposed into the environment. Microbes are useful also in this stage given that the content of organic matter is high. The microbes help decrease the volume of this sludge and the foul smell it emits.
It is not hard to understand why very many plants have employed microbial treatment of wastewater. It has benefits of increased capacity to degrade, higher efficiency and decreased operation costs, microbes also keep the treatment process as natural as possible, which is the ultimate goal of a wastewater treatment plant.
