  • Why do wastewater treatment plants smell bad?
  • Generally speaking, foul odors at treatment plants originate from the anaerobic decomposition of organic compounds. A natural by-product of anaerobic digestion is hydrogen sulfide (H2S), which gives off a strong, nauseating smell. Due to its low solubility in wastewater, it is released into the atmosphere, producing an offensive odor.
  • Why do wastewater treatment plants need odor control covers?
  • Odor control covers can also collect biogas, help regulate temperatures, and reduce greenhouse gas emissions. U npleasant odors at wastewater treatment plants are a reminder that the plant is doing what it is intended to do: treat wastewater.
  • Is odor control a challenge for a sustainable implementation of modern waste treatment plants?
  • In conclusion, odor control is the main challenge for a sustainable implementation of modern waste treatment plants. 1. Introduction Anaerobic digestion and/or composting are currently replacing incineration and landfills in the framework of waste management in modern societies.
  • What are the different odor control technologies in wastewater treatment facilities?
  • Member states of the European Union spend increasing amounts of money to resolve odor nuisance in communities adjacent to wastewater treatment facilities ( Kim et al., 2014 ). There are different odor control technologies in WWTPs, such as chemical scrubbing, biofiltration, biotrickling, bioscrubbing, and adsorption ( Ren et al., 2019 ).
