Features and benefits

---

Dual-shafted grinder

• Dual-shafted, slow-speed, high-torque grinder easily shreds the toughest debris, including rocks, wood, wipes, hair, clothing, plastic and other debris
• Capable of grinding a wider variety of solids than single-shafted machines, macerators, or chopper pumps
• Grinding separates organic from inorganic materials in the waste stream

---

Automated monitoring and controls

• Protect pumps and other critical equipment from costly clogs and damage from tough solids
• Auto load sensing and reversals reduce interrupts and optimize performance

---

Wipes Ready® technology

• Wipes Ready Technology available which prevents materials from forming long strips and reweaving in the waste stream

---

Compact and efficient design

• Adapts to pipelines or channels with little or no modification
• Custom stainless-steel frames allow easy installation in channels, wet wells and pump stations
• Inline 30K Muffin Monster® offers easy removable cartridge maintenance that allows for overhaul without removing the unit from the pipeline

---

Lower operating cost

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

Main applications

The Muffin Monster® sewage grinders are designed to protect pumps and other equipment by grinding down the toughest wastewater solids. Available in three different models each with two different configurations, they are suitable for applications such as:

• Pump stations
• Sludge processing    
• Correctional facilities
• Headworks – primary treatment
• Septage/Grease receiving
• Airports

Wipes Ready® Technology

Muffin Monster sewage grinders are available with the unique Wipes Ready® suite of technologies. It is 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.

The Wipes Ready technologies applied in Muffin 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.

Please note that different Muffin Monster models feature different Wipes Ready options.

Applications

Anaerobic digestion

Anaerobic digestion requires temperature equalization and the proper homogenization of the biomass. Floating crusts must be broken and the formation of foam must be prevented. Sulzer can provide an ideal homogenization solution for many common digester designs.

Network pumping station

Network pumping stations collect municipal wastewater from residential homes and communal schemes. Installed in dry or wet wells, the pumps deliver the effluent to a terminal pumping station. Since most pumping stations are not equipped with screens, the pumps must cope with difficult materials such as fibrous sanitary and packaging items.

Terminal pumping station

Terminal pumping stations receive municipal wastewater from network pumping stations. Installed in dry or wet wells, the pumps forward the medium to a treatment plant for final purification. Due to the lack of screens at most pumping stations, difficult materials such as fibrous sanitary and packaging items are a constant threat to uptime.
