Features and benefits
Dual-shafted grinder

  • Proven low-speed, high-torque dual shafted grinding which can shred the toughest solids
  • Grinds debris smaller than single-shafted machines
  • Grinding separates organic from inorganic materials in the waste stream
High-flow screening drums

  • High flow screening drums to prevent bypass of unshredded solids without compromising flow
  • Standard stainless steel 12 mm perforated drums
Automated monitoring and controls

  • Protect pumps and other critical equipment from costly clogs and damage from tough solids
  • Auto load sensing reduce interrupts and protects the system from damage
  • Adaptive to custom requirements and plant SCADA systems
  • Stores operational data
Wipes Ready™ technology

  • Wipes Ready technology available which prevents materials from forming long strips and reweaving in the waste stream
Lower operating cost

  • Clear pipes and pumps means shorter pump run cycles and lower electrical costs
Main applications

The Channel Monster™ sewage grinders are designed to capture and grind down the toughest wastewater solids in high-flow systems such as:

  • Pump stations where tough solids need to be ground up
  • High flows at the plant’s headworks
Wipes Ready™ Technology

Channel Monster sewage grinders are available with the unique Wipes Ready™ suite of technologies. It was designed to capture all wipes in the waste stream and shred them into small pieces that will not reweave into a ragball in sewage systems.

  • Rotating drum screen: stainless steel
  • Cutters and spacers: hardened alloy steel
  • Shafts: hardened hexagonal steel
  • End housings, covers and side rails: ductile iron

Wipes Ready™ feature availability

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.

  • Muffin Monster prevents sewage pumps from clogging
    January 16, 2020
    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.

  • Case studies
    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 station
    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.

  • Sludge buffer tank
    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.

  • Sludge handling and transfer
    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.
