Solids dewatering focuses on liquid reduction while providing safe handling and disposal of residuals. Slurries contain free liquid and bound liquid. Sedimentation, stationary and moving screens can only remove some of the free liquid, none of the bonded liquid and are only effective with extremely diluted wastes. Doda screw and roller separators accomplish solids separation by squeezing out all of the free liquid plus some of the bound liquid.
The 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.
Manufactured in 304 stainless steel with manual or automatic adjustable weights to control the dry solids consistency of up to 40%.
The roller separator provides a highly efficient and reliable system for the separation of the slurry liquid fraction from the solid one by using a combination of a rotating drum with adjustable compression rollers.
Completely 304 stainless steel with hydraulic adjustable high resistance pressure rollers.
