Oxygen dosing to remove hydrogen sulphide from an anaerobic digester
Did you know that you can remove hydrogen sulphide from an anaerobic digester using oxygen dosing? The oxygen is microdosed into the headspace of the digester where it removes the sulphur.
- Oxygen dosing gives a lower total cost of ownership compared to other methods
- Oxygen dosing is shown to improve the quality of the digested sludge
For this process, the main requirement is to introduce the right mass flow of oxygen, at the right purity. Atlas Copco's oxygen generators provide the required purity with a high flow capacity, and at a controlled cost, making them perfect for dosing anaerobic digesters in biogas and biomethane production.
The benefits of self-generating oxygen for your biogas plant
- Lower operating costs: No rental charges, transport expenses or bulk user evaporation losses (up to 80% more cost-effective vs. delivered; depending on purity, gas and electrical cost).
- Greater safety: No safety hazards when handling high-pressure cylinders.
- Higher productivity: By saving the time that is normally spent on changing tanks, you will ensure that your application runs continuously and without much attention from the operator.
- Better control: Generating your own oxygen means no more ordering, changing and running out of bottles. There will also be no more liquid deliveries to remote locations interrupting production, and you no longer have to deal with suppliers' unpredictable price increases.
- Non-stop availability: 24 hours a day, 7 days a week.
- Reduced footprint: Minimising the visits of trucks for oxygen delivery and any related CO2 emissions.
- Only pay for the purity you need: The OGP & OGP+ ranges supply oxygen concentrations from 90% to 95%. If your application only requires 93% purity for example, this is what the oxygen generator will supply at the touch of a button - there is no need to pay for a higher purity than is necessary. This means that on-site generated oxygen comes at a lower cost per unit than bottled or liquid oxygen. Atlas Copco's oxygen generators use Pressure Swing Adsorption technology to isolate oxygen molecules from other molecules in compressed air to leave high purity oxygen at the outlet of the generator.
Choose the right oxygen supply for your needs
The OGP & OGP+ oxygen generators offer a reliable and continuous source of oxygen gas.
Oxygen self-generation is more cost-effective than bottled/liquid oxygen. It does not leave you reliant on timely deliveries and removes the hassle of getting large trucks into rural locations along small lanes.
With a wide range of oxygen generators to choose from, Atlas Copco brings you the right supply of oxygen to meet your specific needs and optimize your production process at the same time.

Oxygen dosing in the headspace of the anaerobic digester converts the H2S into elemental sulphur. This will minimize the H2S transfer to the gas engine and upgrading plant.
