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 or “mated up” with your filter press, are used to dry filter cakes and bring them from 30% solids to up to 75% solids. 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.

Process

This machine is designed to partner or mate up 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.
