Corrosion and Odours in Sewers |
| Controlling corrosion and odour emissions in sewers
The bacterial degradation process of wastewater passing through sealed pressure pipes rapidly consumes all available oxygen. The resulting anaerobic environment can cause corrosion and generate unpleasant odour emissions in treatment-plant gravity channels and inlet structures.
A corrosion-damaged pressure pipe can be seen on the right.
Our solution
The SOLVOX®-D process injects pure oxygen into wastewater. The volume of oxygen injected is monitored around the clock.
Benefits of oxygen injection
- Elimination of odour emissions
- Prevention of corrosion in concrete or metal
- Improved sedimentation during primary clarification
- Reduced pollution load in biological treatment stage due to preliminary decomposition in pressure pipe
The oxygen injection can be monitored by using an electrical switch box (see picture below).
Additional advantages
- Low investment
- Inexpensive implementation
- No external power supply necessary
- No additional chemical additives required (e.g. iron salts to precipitate H2S)
- No problematic deposits (e.g. iron sulphide sludge during primary clarification)
The picture below shows an Oxygen injection into sewage pressure pipes using SOLVOX®-D.
