The Sludge Dewatering Press is an enclosed high performance sludge dewatering system. It utilizes a central screw and a slowly multi-disk filter to gradually increase pressure on flocculated sludge to produce an dry sludge cake. With electrical, water and polymer usage, and high capture rates the system is very cost effective.
The Sludge Dewatering Press can be provided with all equipment required for dewatering included and factory mounted, piped and wired on a single stainless steel skid. This equipment includes the sludge pump, wash water pump, polymer dosing system and control panel. The system features fully automated one pushbutton startup and shutdown. Once started up the system can run and can be set to shutdown automatically with no operator intervention.
Structure Principle:
The main part of the dehydrator is a filter device that a screw runs through the fixed rings and moving ring.
|
The small gaps between fixed rings and moving ring can filter the sludge, and the carity between screw and rings is filled with flocs. The moving ring transfers the sludge to the end of the machine with pressure and produce sludge cakes. Thickening: When the shaft is driven by the screw, moving rings around the shaft move up and down relatively. Most water is pressed out from the thickening zone and fall down to the filtrate tank for gravity. 
Advantages: The dewatering body is formed by a screw with fixing and moving plates overlapping, as the inner diameter of screw is larger than the moving plate, it do the circular motion with the screw to prevent clogging, to ensure the continuous operation |

① Use three letters and three digits to represent the Model.
The letter MD means machine type—Multi-Disk Screw. Two former digits means the MD cylinder diameter, the last digit shows the number of the screw shafts, such as MD312,it means the MD cylinder diameter is 310mm, the number of the screw shafts is two.
② Sludge Treatment Capacity=DS Standard Capacity÷Sludge Concentration (DS stands for Dried Sludge, 0% moisture.
* Throughput of each model is based on sludge cake with 85% water content.
* There is no certain upper limitation on inlet sludge concentration, however, the target sludge must be flowable.
* Throughput of DAF Sludge is based on sludge containing much fat, oil, and grease such as meat processing applications etc.
* Throughput of Mixed Sludge (Primary Sludge and Waste Activated Sludge) and Aerobically Digested Sludge is based on sludge containing more than 30% fiber (200 mesh) against Total Solids.
