Sewer Network Odor Control

The sewer network cannot be regarded as only a hydraulic collection and transport system but also a system where some major chemical and biological transformations take place. A characteristic example of the effect of biological conversions in networks is hydrogen sulfide (H2S) production. Its production is associated with health risks, corrosion problems of pipe material, operational problems in the WWTP, as well as severe problems with odor emissions.

By controlled dosing of specialized bacteria in sewer pipes,  the following direct results are achieved:
The existing hydrogen sulfide is microbially oxidized.
Further production of hydrogen sulfide is prevented.
Growth of microorganisms prevent any other microbial activity responsible for producing malodorous compounds (e.g. fatty acids).
The prevention of hydrogen sulfide production results in the prevention of its subsequent conversion to sulfuric acid, which is highly corrosive to the piping material.
Dissolving and eliminating fats and accumulated solids in pipelines and sewage pumping stations.
