Channel Monster™ sewage grinders represent the best-in-class technology for wastewater solids reduction. The patented Channel Monster uses rotating screening drums to capture solids and direct them into our proven dual-shafted grinder. The result is a high-flow capacity system that can handle typical solids loading as well as tougher solids like wood and occasional rocks.
Functioning as a pump station grinder, lift station grinder, or headworks grinder - the Channel Monster prevents clogged sewer lines and protects system pumps. Whether installed as a headworks or sewer grinder, the Channel Monster delivers premier solids reduction grinder performance in applications requiring high-flow capacity.
The CMD Channel Monster protects pumps and other sensitive equipment by capturing and grinding the toughest wastewater solids in high-flow systems. It utilizes a rotating drum to capture solids and direct them to a powerful, dual-shafted, slow-speed, high-torque grinder designed to shred the tough solids that typically cause sewer problems.

Channel Monster sewage grinders are available with the unique Wipes Ready technology. It is designed to capture all wipes in the waste stream and shred them into small pieces that will not reweave to form ropes and ragballs that cause problems in sewage systems.
The Wipes Ready technologies applied in Channel Monster sewage
grinders are:
Wipes Ready cutters – A combination of serrated cutters and knurled
spacers cuts wipes in two directions. The result is smaller particles that
cannot reweave downstream.
Delta P Side Rails – Direct solids into the cutters without sacrificing
flow rate and prevent debris build-up in the grinder
Optimized cut control (OCC) – The OCC gear ratio optimizes shaft
speeds to enhance the cutting action and cleaning of the cutters,
which in turn improves the performance and life of the grinder.
Discover how the CDD Channel Monster™ helps the Moygashel wastewater treatment facility in Northern Ireland to protect their fine band screens and screenings compactors.
The pump station in Billerica, Massachusetts, installed a CDD Channel Monster™ with Wipes Ready® technology to protect its equipment from undue stress, damage and unscheduled maintenance.
Reliability is a key characteristic in the wastewater industry where pumps are required to work round-the-clock, especially in pumping stations that transfer wastewater from residential and industrial areas to the treatment plant. However, for one municipality in Sweden, debris in the water was causing significant equipment downtime. Sulzer quickly fixed the issue with the installation of a channel grinder to protect the pumps and minimize unexpected downtime.
Sewage system operators deal with problematic waste such as wet wipes, disposable wipes and other solids flushed down toilets. They spend a lot of resources cleaning their pumps of unwanted solids in the sewage. Our Muffin Monster range, very powerful grinders, break these solids down and prevent pumps from clogging.
Wherever fluids are pumped, mixed, controlled or applied, we are there. See how our solutions create value for customers and learn how we can make your pumping and mixing processes more efficient and profitable, safeguarding your production and ensuring lasting reliability.
Inlet pumping stations are somewhat similar to large terminal pumping stations. Depending on the depth of the incoming sewer, the lifting heads can range from around 2 up to 30 meters. To prevent hydraulic shock loads, which negatively impact the biological process, the stations often make use of variable-speed drives and/or several pumps in parallel.
The sludge buffer tank can be used for a variety of purposes. The most common application is the blending and homogenization of highly concentrated primary, secondary or digested sludge. The solution used to mix the sludge itself, or to mix the sludge with the dosed thickening chemicals, depends on the design and volume of the sludge buffer tank. Submersible mixer types ABS XRW and RW, as well as the agitator type Scaba, can be used to provide highly efficient mixing. Positive displacement, progressing cavity transfer pumps and Muffin Monster™ grinders are used for solids reduction and sludge transfer from sludge feed to sludge dewatering process.
Sulzer pumps, mixers, grinders and agitators are used to condition, transfer, blend and handle sludge. Our progressing cavity, positive displacement pump range, provide a near constant flow rate with suction lift capability, for handling all types of non-Newtonian sludge and cake processes, typically demanded within the wastewater treatment plant. Maintain in place features ensure any process downtime due to the change out of wear components is kept to a minimum. The Muffin Monster™ grinders protect the equipment downstream. The sludge conditioned by grinders will not clog valves, heat exchangers, digesters, centrifuges and other equipment on the sludge line.
