Sewer Odour Control Systems

The underlying process is as follows:    

1. Under the anaerobic (oxygen-free) conditions that are typically experienced in sewers, sulfate is utilized by sulfur reducing bacteria which make up the biofilm at the bottom of sewers pipes. 
2. H2S is produced by the biofilm as a by-product and is dissolved into the  wastewater.   
3. H2S can than diffuse from the liquid phase and enter the headspace of the pipe as a gas, which can then contribute to odours experienced when released from the sewer system. 
4. Corrosion is caused when sulphur oxidizing bacteria, living in the sewer utilize the H2S and  produce sulfuric acid as a by-product, degrading  concrete and metals. 

Depending on site specific parameters, OxyGen can provide systems that halt H2S generation or convert it once it has been formed to protect your systems from corrosion and your residents from odours.  

OxyGen has completed pilot trials and has a full-scale system in operation at a private community in Waterloo. We are happy to set up a site tour to go over the major components!
