In many coolant filtration systems, conveyorized tanks are used to automatically remove the settleable solids and discharge the material into a drum or hopper for disposal. In this process, “free” liquids often get trapped in the solids and accumulate on the surface of the container. This “free” liquid makes container handling and disposal of the material more difficult and less valuable especially for applications using mineral oil.

To remove these “free” liquids from the sludge, Filtertech offers its “Sludge Dewatering Unit”. The Model SDU provides an effective means for removing the fluid from the sludge with minimal operator attention. The Model SDU comes in standard sizes and can be adapted to most conveyorized tank arrangements, either above or below grade configurations. The unit is available in both left and right hand configurations with standard hot rolled steel construction as well as Cor-ten® steel and 304 stainless steel to meet many application needs.
