Spray drying technology can be used to meet zero liquid discharge (ZLD) requirements by reducing or eliminating liquid waste streams from a variety of sources. It has been successfully utilized in power generation applications for more than 40 years to remove SO2 from flue gas.
Applications include:
- Spray dryer absorber (SDA) flue gas desulfurization (FGD) for coal, oil, and high-chloride fuels (e.g., municipal solid waste)
- Elimination of wastewater from wet FGDs
- Evaporation of existing ponds
- Evaporation of other liquid effluent or waste streams
