Sludge Dewatering Equipment: Continuous Sludge Dryers
***NOT FOR BIO SLUDGE***
The M.W. Watermark™ Continuous Sludge Dryer is designed for volume and weight reduction of metal hydroxide plating waste.
M.W. Watermark™ holds a commitment to providing innovation for the water and wastewater treatment industry which is well renowned. That is why we are constantly working on improving and redesigning machinery to introduce to the world. With that in mind, our engineers have produced the M.W. Watermark™ Continuous Sludge Dryer, which can reduce waste volume and weight significantly, offering an average yearly savings of nearly 60%.

About the M.W. Watermark™ Continuous Sludge Dryer
We offer the M.W. Watermark™ Continuous Sludge Dryer in two models, the DM-200G and the DM-380G. At full capacity, the DM-200G can process up to three cubic feet of material in an hour, while the larger DM-380G can process double that, or six cubic feet. These machines are designed to process metal hydroxide plating wastes, and, when used in conjunction with your filter press, are used to dry filter cakes and bring them from 30% solids to up to 75% solids*.
*Typical results. Actual results may vary.
The M.W. Watermark™ Continuous Sludge Dryer offers several improvements in efficiency and simplicity over other continuous dryers. These improvements include a drop-in footprint for compatibility and ease of installation, a PLC with full-color touch screen and fault alarms, stainless steel cake hopper, easy external access to high-temperature bearings, an over-sized extruder gearbox with AC drive and inverter duty motor, and durable stainless steel construction of all wetted components.
M.W. Watermark™ also offers maintenance and repair services for our own line of sludge dryers and as well as models from other suppliers. We will also continue to offer aftermarket support for other brands of dryers.
Our continuous sludge dryer is designed to be used in conjunction with a filter press, which dewaters metal hydroxide slurries from metal plating operations. The filter cake that is produced by the filter press is dumped into the sludge dryer receiving hopper (A). Wiper blades push the filter cake through a stainless steel screen, decreasing the material’s size and shaping it for increased surface-area and efficient drying (B, C). Next, the noodle-shaped material falls onto a continuous stainless steel mesh belt, where it passes under a series of infrared heaters for drying (D). The heat is produced by natural or LP gas, while ambient air is drawn through the heat chamber by a fan mounted on the inlet of the wet scrubber (E). After significant reduction, the dry, granular material exits the dryer into a container for removal.
