Wastewater treatment plants are some of the most challenging environments due to the aggressive nature of the material treated.
Organic matter, bacteria, suspended solids, aggressive gases, etc., present difficult challenges for treatment facilities, pipelines, and pumping stations. Steel and concrete assets in these facilities are subject to harsh conditions.
- The usual long-term threats to reinforced concrete are carbon dioxide, acid, and freeze-thaw cycles.
- Turbulent flows and suspended solids can cause abrasion and erosion.
- High sulfate levels and biogenically induced acid create aggressive environments.
The treatment process can lead to rapid deterioration of concrete surfaces and corrosion of concrete reinforcement and steel structures.
