The danger of H2S (hydrogen disulphide)
Hydrogen sulfide is a component produced by many industries, such as food processing, wastewater treatment, etc. H2S ((di)hydrogen sulphide, hydrogen disulphide or hydrogen sulphide gas) is a toxic and flammable gas with a foul rotten egg smell. Because of this toxicity, it is important to eliminate this component.
Effectiveness of H2S removal with a biological air scrubber
The removal efficiency with this method is about 95%. This means that no odours are released into the environment. A simple odour measurement or olfactometry will suffice to see this.
One of the main advantages of this disposal technique is its very low operating cost. This is because no constant supply of chemicals is required, as is the case with chemical gas scrubbers. Learn more about biogas desulphurisation?
