New ‘monster’ for pump stations

The Channel Monster XD 3.0 is reportedly the world's largest, most powerful sewage grinder and is 13 feet (4m) tall, weighing 9300 lbs (4220 kg) and producing 7 tons of cutting force at peak loads.

It incorporates rotating screening drums and a Muffin Monster 15 hp (11 kW) grinder to shred solids while processing up to 59 million gallons per day (9306 m3/h. The grinder has larger 3 inch (76mm) hex drive shafts and stainless steel coil drums with ½ inch (12mm) diameter rod. It can shred rags, plastics, wood, and trash so particles flow easily through pumps and pipelines. The Channel Monster XD 3.0 also includes 1 hp (0.75 kW) motor for the drums. This new design features larger cutters, shafts and housings so the grinder can process heavy debris and first flush storm loading. "We designed thicker cutters for a longer service life," said Rob Sabol, JWC's director of engineering. "Bigger cutters also help the process - solids are ground up so they pass through pumps but are still large enough for headworks screens to capture and remove them."
