Why Is Wastewater Aerated?

Aeration is the process by which air is circulated through, mixed with, or dissolved in a liquid. So why is this important in the treatment of wastewater? When wastewater is treated, the main goal is to create purified water that can once again be used as a resource; a critical component in wastewater treatment is bacteria.

Protozoa are single-celled eukaryotes that feed on organic matter, such as other microorganisms or organic tissues and debris. Rotifers are microscopic aquatic animals of the phylum Rotifera. Rotifers can be found in many freshwater environments and in moist soil, where they inhabit the thin films of water that are formed around soil particles. These two bacteria are thought of as purifying bacteria and are largely present inside wastewater tanks. A further commonality between the two is that they require oxygen to survive, thrive and purify.

In municipal and industrial wastewater treatment, aeration is part of the stage known as the secondary treatment process. This is where oxygen is essentially pumped into the tank to be utilised by the bacteria. The bacteria break down the organic matter containing carbon to form carbon dioxide and water. If sufficient oxygen were to be withheld from the process, the mentioned bacteria, along with other types, would not able to biodegrade the incoming organic matter in a time effective manner. And, in the absence of oxygen, degradation occurs. This is odorous and does not allow for a complete breakdown of pollutants.

Aerated Wastewater Treatment System

Aeration, and therefore the activated sludge process, is the most critical component of a wastewater treatment system. In acknowledgment of this, EcoSeptic offers aerated wastewater treatment systems. Installation of a tank is not all that we offer, as we are committed to both water sustainability and our valid customers who, like us, recognise the importance of preserving and recycling such a valuable natural resource; we will service, repair and carry out maintenance of the system as it is required. We will ensure, upon installation, that you understand how to care for your tank.
