Agitated Thin Film Dryer (ATFD)
The Agitated Thin Film Dryer (ATFD) is an advanced drying system used to concentrate and dry high-solid, viscous, and heat-sensitive liquids into powder or flakes. In wastewater and effluent treatment systems, ATFD is typically used for the final stage to achieve zero liquid discharge (ZLD) by converting slurry into dry solids.
