Accepted Norms:
- Untreated hydrogen sulfide in a wastewater collection system can cause serious odor issues resulting in complaints from the public. In recent years, however, corrosion has surpassed odor as the leading constituent in untreated hydrogen sulfide. The collection system isn’t the only entity that can fall ill to the dangers of hydrogen sulfide production. The WWTP can also succumb to the negative effects of H2S corrosion in the following areas:
- sludge thickeners and dewatering equipment
- electronic controls
- carbon steel
- influent infrastructure
- flow meters
- bar screen electronics
- pipelines
2. In the water distribution line, corrosion occurs when metals oxidize with oxygen-rich water. This results in metal oxides that precipitate out at the tap. The corrosion issues in drinking water lines can be detrimental to the health of customers and negatively impact the overall quality (taste, smell, aesthetic) of finished water. Furthermore, older water systems with lead pipes must be analyzed in order to avoid elevated lead concentrations and to meet the requirements of the EPA’s lead (and copper) rule.
