FGD Wastewater: Industry Perspectives

摘要

1. Physical/chemical plus biological treatment for FGD wastewater requires a lot of lead time for optimization (minimum 6 months to 1 year). 2. There is great uncertainty over the limits that can be consistently achieved using this technology. 3. The power industry needs the flexibility to switch fuels based on market conditions and other factors. 4. FGD wastewater treatment limits should account for the variability that will occur due to many factors, including: 4.1 Fuel switching 4.2 Cycling of units 4.3 Changes in air emission technologies to comply with air regulations 4.4 Unit load.
