What is pure oxygen Aeration?
Pure oxygen is presence of only and only oxygen molecules which is different from air.
We say we breathe in oxygen and breathe our carbon di-oxide but in reality we take oxygen from the air which is a mixture of gases through our delicate respiratory systems.
It’s a truth that each part of the ecosystem requires oxygen to survive. In truth, the principle duty of the body’s respiration machine — is to soak up oxygen and breathe out carbon dioxide.
Is aeration the similar process?
Aeration is a familiar process that most of us understand and experience.
Have you ever blown a bubble into a liquid from a straw or seen a jet of water from a decorative fountain?
Aeration is used to mix, circulate, or dissolve air in either a liquid or other substance but what is pure oxygen aeration?
This process is often used in wastewater treatment.
Wastewater or dirty water is exposed to air through an aeration mixer or aerator. When air is added to water, some of the existing gases such as carbon dioxide and hydrogen sulphide are released. This is useful in the activated sludge treatment process, in which sludge and effluent are mixed together. The addition of air enables microorganisms to use available oxygen to break down organic materials.
Pure oxygen in Waste Water Treatment
In wastewater treatment, aeration is the process by which air dissolves in water. This allows aerobic bacteria to grow on key pollutant parameters such as biochemical oxygen demand (BOD) and ammonia during processing.
However, there are limits to ventilation. The air we breathe has 21% oxygen. Adding oxygento wastewater has several benefits.
"Pure oxygen" represents a gaseous mixture containing more than 90% oxygen. Pure oxygen aeration is based on the idea that pure oxygen increases the wastewater treatment capacity of a given capacity of the aeration tank. In addition, the use of pure oxygen avoids the compression and stripping of large amounts of nitrogen, resulting in lower energy requirements and emissions than normal aeration.
Addition of pure oxygen
Pure oxygen aeration is best for floating aerators with high oxygen transfer efficiency. The suction aerator combines aeration and mixing under the surface of drainage. The angle can be adjusted, making it ideal for ventilation in the lagoon.
What can we determine about pure oxygen addition in WWTPs?
Since the life cycle cost of pure oxygen aeration is usually higher than conventional aeration, consider dealing with specific issues such as capacity limitation, low oxygen problem, odour, emissions, performance limitations, all needs to be addressed. In the right circumstances, pure oxygen aeration provides an attractive total cost of ownership and can address some of the major challenges facing wastewater treatment plants today.
Characteristics enhanced by Aeration:
1. Reduction of VOCs and odour;
2. Reduction of operating time of aeration;
3. Higher efficiency of aeration.
