Air2Air enables power plants to recover much of the water that typically would be evaporated if using a standard cooling tower, which could help a power plant to reduce its annual water consumption by as much as 20 percent, according to the manufacturer. The water recovery system reportedly reduces water consumption while maintaining overall steam turbine efficiency. For example, a typical 500-MW coal plant in the U.S. uses roughly 30,000 tons of water each day. Such a cooling tower fitted with this technology can reclaim up to 10,000 tons of water each day, says the manufacturer. Recovered water can be returned directly to the tower basin or piped away for other plant uses.
