Sludge Dewatering Decanter Centrifuges | Sludge Thickening
Centrifuges in Wastewater Treatment:
Solutions for Municipal Water Management
Engineered, Designed and Manufactured in the U.S.A.
Built From the Ground Up
In 1987, the first Centrisys centrifuge was designed and built around what was learned in the field by servicing competitor’s equipment in both municipal and industrial applications.

Based in Kenosha, Wisconsin, Centrisys is the only U.S.A. manufacturer of decanter centrifuges for municipal wastewater and one of the few companies in the world focused solely on centrifuge technology. The Centrisys team collaborates together to bring fresh perspectives and continuous learning to tackle the toughest challenges in municipal water and wastewater.
Lowest Life-Cycle Cost
Centrisys provides the most cost-effective option for owning, operating and maintaining a decanter centrifuge.
All this equates to costs savings for municipal treatment plants. A Centrisys centrifuge delivers the driest cake at the lowest hp per gpm of flow. These results deliver savings for our customers year after year.
- Higher capacity
- Increased throughput
- Drier cake
- Lower energy consumption
- Reduced polymer consumption
- Fewer service requirements
- More process flexibility

A Trusted Partner
It’s our years of dewatering and thickening in municipal markets, along with operating and servicing our competitor’s equipment, that gives Centrisys the advantage in water and wastewater applications. Before we specify one of our standard Centrisys centrifuge models, we want to hear more about your plant's process goals and analyze your sludge. After this, we can determine if one of our standard centrifuge designs or a custom solution will deliver the best results.
It’s our team’s based approach to understand the deliverables of each project that brings value to our customers.
