Sewage treatment plants have the potential to generate unpleasant odorous gases, a persistent nuisance to nearby residents. The inlet collection area and sludge treatment facility release hydrogen sulphide (H₂S), which smells like rotten egg. Due to its low solubility in wastewater, it is released into the atmosphere, producing offensive odours.
Hydrogen sulphide from sewage collection tanks and screening chambers creates a strong rotten-egg smell which affect residents.
Sewage treatment plants that fail odour control can risk penalties from local authorities and complaints from the public.
Odour is generated across the entire plant from the pre-treatment inlet system through to the sludge treatment facility.
With multiple odour control technologies available, choosing the right system for your plant's size and efficiency is challenging.
