What Does Aeration Do For Wastewater Systems?

About Me
Protecting Your Home

When we moved into a more rural part of the country, I was surprised by how many things were different. In addition to having a septic tank, we also had a water well that we had to figure out how to service. However, we quickly learned everything we needed to know, and before I knew it, I was moving in to a place that I felt really good about. Now I can see that all of those little services are a serious benefit, since they help to reduce our monthly costs.

Wastewater treatment services are essential for ensuring the safe disposal of sewage and the production of fresh, clean water. Within the wastewater treatment system is an aeration process that helps to break down organic matter and pollutants in the water. Understanding the role that aeration plays and its importance helps you get a better understanding of the entire treatment process.

The Aeration Process

Aeration is the process of introducing air into the wastewater to encourage microorganism growth. Those microorganisms help to facilitate the oxidation of organic compounds. This aeration process mimics the environment's natural ability to break down pollutants in rivers, lakes, and similar bodies of water. In water treatment, aeration usually happens with a series of mechanical devices that inject air directly into the water.

Enhanced Microbial Activity

Aerating wastewater boosts microbial activity. Microorganisms, including fungi and bacteria, help the organic matter in the wastewater break down. Those microorganisms need oxygen to survive and function, so aerating the water helps them thrive and break down waste and contaminants properly. This accelerates the decomposition process to purify the water.

Removal of Harmful Substances

Aeration also helps to remove ammonia and hydrogen sulfide from wastewater. Ammonia is commonly found in sewage, and it can be toxic to aquatic life. Aeration helps convert ammonia into nitrate and nitrite ions. Additionally, aeration reduces hydrogen sulfide, which corrodes equipment and produces foul odors.

Improved Settling and Clarification

Aerated wastewater settles and clarifies more easily and more efficiently. During the aeration process, fine particles and flocs are formed and are later removed in settling. This creates clearer, cleaner water that is easier to treat in later stages. The clearer you can get the water now, the less additional intervention it needs later.

Energy Efficiency Considerations

Aeration is important for effective wastewater treatment, but facilities also need to balance energy consumption. The energy required for aeration is often significant, but facilities can regulate that demand through adjustments of the aeration rate based on the needs of the water coming into the system.

Aeration plays an important part in the water treatment process. Ensuring access to fresh, clean water is a priority all over the globe, and the aeration process is just one step in making that happen. When you understand the process and its benefits, it's easier to embrace it in your water treatment operation. Consider your current structure and incorporate aeration equipment to help improve the purification process in your operation.
