Odor Management

Providing preventative solutions to help minimize odors

We are committed to reducing odor pollution

Veolia Water Technologies has invested in research and development activities for many years to develop odor-free treatment plants that suit both operating personnel and keep local residents happy.

Committed to water treatment for more than a century, Veolia Water Technologies has acquired a solid knowledge base concerning the issues arising from odor pollution. This can come from stagnant effluents, contained in basins or lagoons before being rejected or treated.


Odor nuisance: what are the main causes?

We’re all familiar with bad smells around industrial complexes. Smells similar to "rotten eggs" or "cabbage" are among the most common complaints of local residents. 

The main sources of bad odors?

  • Sludge storage
  • Dehydration

They are caused by the decomposition of chemical elements that are found in the recycling of industrial effluents.

It was not until the 2000s that site operators causing odor pollution began to really consider the disruption they were causing in the absence of adequate effluent treatments. While the commercialization of anti-odor processes for the industry has been slow to emerge, prefectural decrees now define the tolerated levels of odors emitted by industry. Maximum levels can also be set during requests for tenders.

The nuisance caused by bad odors has not always been given the attention it deserves. We now know that it varies according to several factors, such as:

  • Frequency
  • Duration of exposure to bad odors
  • Weather conditions
  • Time of year
  • Geographical environment
  • Individual reactions to the smells themselves

Although water purification, pumping and sludge treatment plants play a role in protecting the environment, they too become sources of nuisance if not treated properly. The nuisances may be:

  • Visual
  • Noise-related
  • Odor-related, particularly in urban areas

This is why Veolia Water Technologies is extremely attentive to technology performance in this area, as it helps improve the quality of life for all. We help industries and municipalities deal with odors emitted during wastewater treatment. We have preventative solutions that can help minimize nuisance:

  • Pond covers to minimize nuisance for local residents
  • Knowhow in biochemistry and sustainable development for a comprehensive solution to the problem
