Centrisys/CNP
About
Centrisys/CNP is a U.S.-based manufacturer of decanter centrifuge systems and advanced biosolids process technologies, headquartered in Kenosha, Wisconsin. The company holds ISO 9001:2015 certification and is Build America, Buy America (BABA) compliant, designing and engineering its equipment domestically. Operating under two brands—Centrisys for centrifuge equipment and CNP for process technologies—the company serves municipal water and wastewater, oil and gas, mining and minerals, pulp and paper, food and beverage, animal protein, dairy manure, steel and primary metals, and tunneling markets. The CS-Series dewatering centrifuges provide mechanical sludge dewatering with models including the CS21-4 and CS26-4, designed for low energy consumption and maximum uptime. The THK-Series sludge thickener operates without polymer addition, a patented approach that reduces operating costs. The DLT-Series low-temperature belt dryer offers compact, modular biosolids drying with USA-sourced parts. The CD-Series vertical cuttings dryer recovers drilling fluids from oil and gas drill cuttings. CNP process technologies include PONDUS thermal hydrolysis for intensifying anaerobic digestion and boosting biogas output, MagPrex for struvite removal and phosphorus recovery, and CalPrex for phosphorus index management. Centrisys also provides the ROTODIFF hydraulic backdrive system, mobile and containerized centrifuge systems, rental fleet services, and 24/7 nationwide repair covering all centrifuge brands.
Key Products
Decanter centrifuge for mechanical dewatering of municipal and industrial sludge, producing dry cake solids with high solids capture rates.
Patented centrifuge-based sludge thickener that achieves thickening without polymer addition, reducing operating costs for wastewater treatment plants.
Belt dryer for biosolids drying that uses low-temperature thermal processes to reduce sludge volume and produce Class A biosolids with simple operation and maintenance.
Vertical centrifuge for solids-liquid separation in oil and gas drilling operations, recovering drilling fluid from cuttings.
Thermal hydrolysis technology that intensifies the anaerobic digestion process, increasing biogas production and reducing biosolids volume for wastewater treatment plants.
Process technology for struvite removal and phosphorus recovery from wastewater treatment sidestreams, preventing struvite scaling while recovering valuable phosphorus as a fertilizer product.
Phosphorus recovery and management system that captures phosphorus from wastewater biosolids processing streams for beneficial reuse.
Hydraulic scroll drive technology for centrifuges that provides precise differential speed control for optimized sludge dewatering performance.
Transportable and containerized centrifuge systems for temporary or mobile dewatering operations at wastewater treatment plants and industrial sites.
Short-term and long-term rental decanter centrifuge systems available for pilot testing, seasonal needs, or equipment downtime situations.
24/7 nationwide and global centrifuge repair service covering all manufacturer brands, including emergency response, preventive maintenance, and full rebuilds.
Factory upgrade and retrofit services for existing centrifuge installations to improve performance, efficiency, and reliability regardless of original manufacturer.
