Spray drying evaporation for wastewater treatment
Industries emitting wastewater with salts and solid particles face regulatory and environmental mandates to minimize liquid discharge. Traditional methods often require substantial energy and additional filtering systems, leading to higher operational costs and maintenance burdens.
Convert wastewater into dry powder
The GEA Spray Drying Evaporation (SDE) system is an efficient technology for treating industrial effluents. Utilizing hot flue gas to evaporate water from wastewater, the system leaves a fine dry powder that’s easier to handle and dispose of without liquid discharge. This process integrates seamlessly into various industrial setups, making use of existing heat sources like flue gas or pre-heated combustion air. The GEA SDE system features a well-proven rotary atomizer, ensuring precise droplet size distribution and consistent drying performance. Applicable in industries such as power, waste to energy, and metallurgy, the system is designed with flexibility and efficiency in mind, featuring carbon steel construction for durability.
