Wipes Ready technology

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.

    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.

  • Grinding out success
    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.

    A Sulzer Channel Monster has been a lifeline for a large-scale wastewater treatment project in Vác, Hungary

  • Preventing sewage pumps from clogging
    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.

Applications
  • 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.
