- Temperatures regularly drop below freezing in Albany, New York during winter, creating challenges for water treatment equipment at a power station. The clarifier unit that is important for water treatment tends to freeze.
- Joe Ruggiero, a senior environmental engineer, came up with a solution to prevent the clarifier from freezing by recycling heated blowdown water from heat recovery steam generator units to warm the clarifier.
- Implementing this approach would have multiple benefits - it would considerably reduce discharge to the nearby river by reusing the blowdown water, help ensure reliable station operations, and be better for the environment.
