Muffin Monster Grinders

In 1973, JWCE invented the Muffin Monster, the world’s first dual-shafted wastewater grinder. The Muffin Monster line of waste grinders performed so well, and made such an impact, that they virtually changed the typical Wastewater Treatment System design from that point forward.

Today, JWCE has shipped over 35,000 waste shredders and screens worldwide and is committed to providing customers with cutting edge technologies, services and value. ACG-Envirocan is proud to represent JWC products across Ontario.

Muffin Monster Grinders lead the industry in performance and efficiency. These reliable assets are proven to provide municipal facilities with the wastewater treatment solutions they’re looking for, from reducing solids to keeping your system running smoothly. We have a product that can grind in any application imaginable, whether it’s sludge, sanitary wipes or rags.

The Muffin Monster line includes grinders specifically designed to provide high flow capacities and easy serviceability in sewage applications. We also have grinders ideal for smaller wastewater pump stations, or high-flow wastewater grinders for headworks. All Muffin Monster grinders have best-in-class technology for wastewater solids reduction while providing great flexibility. All Muffin Monster units provide operators with class-leading capacity while capturing and shredding rags, rocks, wood, and other solids into small pieces to pass through pumps, pipes, and process equipment.

Muffin Monster Grinders are also used in a wide variety of industrial applications including manufacturing facilities where solids reduction is a necessary procedure in pre or post-production processing, office buildings, agricultural operations, resorts & theme parks, correctional facilities, and many more.

Multiple Muffin Monster Installation Options

The Muffin Monster line offers configurations to suit every system and application.  Open channel, in-line and manhole grinders, all manufactured to the same high-quality standards

Intelligent Design

Debris in your wastewater stream varies by level. 

Commonly, there are hard, abrasive materials such as rock and sand at the bottom, materials that float in the waste stream, such as stringy wipes and food scraps are at mid-level, and above the wastewater, the air is often high in H2S, which creates a corrosive environment. Choosing a single cutter type for a grinder may address one challenge while ignoring the others.

The Right Cutter at the Right Location

The JWC Monster Stack is a customized cutter stack designed specifically for your application, that gives you the right cutters at the right location to meet the expected challenges in your wastewater environment.
