Screw Separator

Doda’s Screw Separator—with its compact design, easy installation and simple to maintain features—is an excellent machine for the separation of solids from liquids and sludges. It uses an auger rotating at 30 RPM inside two wedge wire screens.

Our heavy duty screens come in a variety of sizes – 1.0mm, 0.75mm, 0.50mm, 0.25mm are standard. Other sizes are available upon request. Choosing a larger screen in the first stage of the separation for fast dewatering and a smaller opening screen for the final compression stage resulting in a higher capture rate of solids is a popular, effective option. Our knowledgeable team is available to help you determine the optimal configuration for your waste management needs.
