Top Quality · Great Reliability · High Durability


Solids dewatering focuses on liquid reduction while providing safe handling and disposal of residuals at a wastewater treatment facility. Slurries contain free liquid and bound liquid. Sedimentation, stationary and moving screens can only remove some of the free liquid and none of the bonded liquid and are only effective with extremely dilutedwastes, which complicate the problem. Doda screw and roller separators accomplish solids separation by squeezing out all of the free liquid plus some of the bound liquid.

With its compact design, easy installation and simple to maintain features the Doda screw press separator is an excellent machine for the separation of suspended solids from liquids and sludges.
