Wastewater Processing With a Grinder

Jane Cooper

A grinder is ideal for your wastewater processing and treatment applications. A grinder like the Dimminutor provides an effective and low-maintenance solution for reducing the solids in your wastewater.

Find out more about grinders and their role in wastewater processing. You'll be ready to take the first step toward improving your wastewater processing.

What Is a Wastewater Grinder?

A grinder uses abrasion and often compression as well to reduce solid materials into small particles. Our grinders typically use cutters, in particular our Cutter Cartridge Technology, to pulverize material. They can handle solids like plastics, vegetable matter, and disposable wipes.

A wastewater grinder protects downstream equipment from large debris. For example, solids can clog the pump impellers, digestors, and nozzles in the sewage treatment process. Grinders can easily pay for themselves by preventing damage and downtime.

Open Channel vs. In-Line

A wastewater grinder can either be an open channel or in-line. An open channel grinder fits into a straight-through channel, wet well, or water inlet.

An in-line grinder fits directly into the pipeline. You'll need an in-line grinder if you have a dry pumping station.

Dual Shaft Grinders

A dual shaft grinder has two shafts of blades. They rotate toward one another at different speeds, which helps clear the blades of debris.

Dual shaft grinders are very effective when it comes to wastewater processing.

How Does a Grinder Help with Wastewater Processing?

Cleaning and purifying the recaptured water is a critical part of wastewater processing. A grinder makes this process work more efficiently.

First the grinder removes larger solids from the process water. This starts cleaning the water for reuse.

Once the large solids are removed, it goes through a pumping station and into a fine screen that removes even smaller debris.

Downstream processes remove particles and polluting materials from the wastewater, in addition to other remaining contaminants. Some processes have waste materials that you can reuse. After removing this material from the water, you can put it back into the production process.

Benefits of Wastewater Processing

Wastewater processing has benefits for the environment and your business.

You spend less on effluent disposal because your waste volume is less. This leads to lower costs for storage, transportation, and disposal. You reduce your costs by handling some of the material yourself.

Using processed wastewater and materials is naturally good for the environment too. You use fewer raw materials, which puts less strain on resources, and you use less energy because you don't need to pump in as much water.

Why Choose a Dimminutor Grinder?

A grinder like the Dimminutor has many advantages for your wastewater processing program. It's easy to use and maintain.

The Dimminutor grinder has three interchangeable cutters, which you can remove or adjust independently. They work in both directions.

You can also rotate the cutters to ensure that they wear evenly.

The cutters are made from hardened stainless steel and the screens are made from stainless steel plates. Producing the screens with laser cutting technology makes them highly precise and durable.

Ultimately, the design of the Dimminutor lets you avoid some of the issues you may find with other grinders.

Unlike other grinders, the Dimminutor's cutters penetrate the individual slots of the screen. This lets the cutters clear the screen with each revolution.

The Dimminutor is cantilevered, so it doesn't have seals or bearings near the gritty channel floor. The screen doesn't move, and it doesn't rub against the bottom grit either. This saves wear and tear on the unit.

The seals and bearings are also immersed in an oil bath, which helps provide a longer life and less maintenance required.

How Does the Dimminutor Work?

You can install the Dimminutor in a straight-through channel, wet well, or water inlet. It will handle full or occasional submergence.

The wastewater passes through the grinder with minimal pressure loss and the flow will remain unobstructed even during reversing cycles.

Solid matter arrives with the fluid current and reaches the rotary blades. The cutters grab the foreign matter and draw it in with its smooth, continuously rotating design.

The low speed and high torque provide good performance with low drive power as the blades rip and grind up solid, coarse, or brittle material. It cuts long-fibered material into pieces.

The Dimminutor grinder doesn't have gaps or openings between the cutters and the screen. It gives you a controlled output and complete grinding of solid matter.
