How does liquid oxygen improve wastewater treatment?

How Does Liquid Oxygen Improve Wastewater Treatment? Liquid Oxygen helps biological wastewater treatment plants by increasing their capacity and by helping to settle upset conditions quickly.

What is liquid oxygen used for?

There are several ways that the use of pure oxygen can help to ensure the system operates correctly and has this needed oxygen level with fewer detrimental impacts.

What happens when you add air to wastewater?

When air is added to wastewater, it can strip hydrogen sulfide and/or VOCs (volatile organic compounds such as benzene, toluene or methanol) that might be present during the aeration process. Compared to the traditional compressed air approach, pure oxygen often achieves a higher level of dissolved oxygen.

How is oxygen injected?

Finally, the oxygen is injected. There are several methods of injection. Simple devices such as spargers, diffusers or porous hoses can be used. More complex devices can provide additional mixing energy and typically improve transfer efficiency. These devices can be floating, sit on the bottom of the basin, or even be side stream and will vary based on the applicable criteria (e.g. basin depth and size, quantity of O2 needed, need for mixing, availability of power, and many other factors).

What does an oxygen supplier look for in a plant?

A well-informed oxygen supplier specialist will look at each individual site situation to design a solution that meets the unique needs of a specific plant. This will take into account oxygen demand, as well as criteria such as the water depth and existing aeration equipment.

quaternary purification, involving the removal of specific substances which are characteristic of the waste water flow.

How is wastewater treated?

In industrial and municipal wastewater treatment plants, oxygen is injected during the secondary treatment process. Also known as the activated sludge process, the oxygen is pumped into the wastewater tank to encourage the growth of the bacteria. As the bacteria consume the organic matter, they form flocs, which quickly settle out and become separated in a different tank. This cycle is repeated continuously to make sure the decomposition process is as quick as possible.

What is the function of bacteria in wastewater?

Bacteria are an important part of wastewater—they break down the organic matter found in wastewater and convert it to carbon dioxide and water. While the bacteria can get the job done on their own, it takes an incredibly long time, and is not nearly as effective. In fact, instead of being converted to carbon dioxide and water, the wastewater can create hydrogen sulfide, which then transforms carbon into methane. Some of the carbon will be become organic acids, which will make the water harder to treat and lead to odor formation.

Does wastewater have a chemical reaction?

If left to its own devices, wastewater takes a very long time to naturally biodegrade. And, as it sits, it creates an intense odor and potent chemical reactions. Luckily, there is a way to speed along the process so the organic matter can biodegrade and the smell can diminish. As such, the water needs to be treated. Some treatment plants opt for chemical treatments to stabilize the contaminants; however, by injecting the wastewater with oxygen (a.k.a. aeration), the same benefits can be achieved.

Why is liquid oxygen important?
