  • Dewatering Decanter Centrifuges CS Series

    The Right Solution, The Fastest Payback

    In 1987, Centrisys designed and built its first centrifuge around what was learned in the field by servicing competitor’s equipment in both municipal and industrial applications. Thirty years later, the Centrisys engineering team continues to benefit from problem-solving, learning what does and does not work in the real world and takes that knowledge to continue Centrisys’ lifelong commitment to brand excellence. By providing the most efficient, robust decanter centrifuges, Centrisys gives our customers the results they need.

  • Sludge Thickener THK Series

    The Most Efficient Solution to Thicken Sludge

    The Centrisys Sludge Thickener (THK Series) is specifically engineered to achieve high-performance thickening of biosolids. The non-conical design results in greater G-volume, allowing for the highest capacity of flow to the centrifuge. The THK improves upon existing technologies using fundamental principles of a 1) Centrifuge - 3,000 Gs, 2) Rotary Drum Thickener - fully enclosed and small footprint, 3) Dissolved Air Flotation (DAFT) - air injection. The patented Hydro-Pneumatic design has proven that NO polymer is required under normal conditions (150 SVI)

  • Screw Press SP Series

    Maintenance is a Breeze

    With four divided screens, the Centrisys SP20 is simple to operate, maintain and clean. The four screen baskets and horizontal design allow for most maintenance to be completed without removing the screw shaft. There is no need to pull the auger out; simply open the maintenance cover to clean. The SP20 combines a longer screen design and dual filtrate zones to create dryer cake solids, cleaner centrate and maximum water drainage. Two filtrate zones allow for the separate collection of clean and dirty centrate. The longer screen design increases retention time by using the entire length of the screw for dewatering.

  • PONDUS: Thermo-Chemical Hydrolosys Process (TCHP)

    PONDUS keeps the hydrolysis process simple and affordable – even for smaller plants!

    Drastically reducing the overall carbon footprint by minimizing solid waste production, PONDUS enables useful repurposing of biosolids (as fertilizer and carbon source) and methane gas outputs (as renewable energy). Using caustic soda and hot water to destroy cell membranes of Waste Activated Sludge (WAS), organic acids are released in the process.

  • Sülzle Klein Dryer

    Low-Temperature Dryer

    Centrisys/CNP is an exclusive NA distributor for Sülzle Klein dryers. The first U.S. installation of a Compact-Dry was in 2015 at Kenosha, WI. This is a dual belt, low temperature, sludge dryer. The dewatered biosolids are fed at +30% DS and dried to over 90% DS. Since dryer optimization, the biosolids disposal weight is reduced to one-third and are certified as Class A with exceptional quality.
