Spray drying evaporation for wastewater treatment
Achieve efficient zero liquid discharge with this spray drying evaporation system, which transforms wastewater and flue gas effluents into collectable dry solids, ensuring cleaner emissions and environmental compliance.
Evaporates and Dries Industrial Waste Streams
The Spray Drying Evaporation (SDE) System by GEA revolutionizes wastewater treatment in power and waste-to-energy sectors by converting liquid effluents into dry, manageable solids. Leveraging GEA’s well-proven spray drying and proprietary rotary atomization technology, the SDE system provides a seamless integration into existing flue-gas desulfurization (FGD) processes. It operates via the evaporation of water from contaminated streams using hot flue gases, which results in a fine dry powder captured by a downstream filter, achieving zero liquid discharge effectively.
Designed for high efficiency and continuous operation, the system can be customized to handle varying hot gas temperatures and effluent capacities, employing a range of atomizer sizes based on specific requirements. Automation is enhanced with precise control over gas distribution and droplet size, ensuring complete conversion with minimized energy consumption. Constructed from carbon steel with optional material configurations, it offers substantial resistance to corrosion and operational longevity.
Ideal for industries focusing on environmental compliance, the Spray Drying Evaporation System manufactures end products like dry salts, metal oxides, and sulfate solids, with the capability to purify gases free of heavy metals. Incorporating optional features like specific dust collectors or the main filter enhances flexibility and performance in diverse industrial applications.
