The Centrisys/CNP THK Sludge Thickener Improves Municipal and Industrial Wastewater Applications

With eight purchase orders in the last 3 months, the company’s sludge thickener has been used in several wastewater treatment facilities and wineries.

THK 600In the last few years, the U.S. has undergone a series of innovations and technology advancements. These changes have impacted several industries, leading them to save energy and resources. One such industry is wastewater treatment. Seven wastewater treatment plants in San Antonio, TX; Lincoln, NE; Belvidere, IL; Grandville, MI; Fargo, ND; University of Florida, Beijing airport and an East coast winery have benefited from the Centrisys/CNP THK sludge thickener. It offers proven performance with lower life cycle costs, less or zero polymer, higher G-volume for higher capacity and less redundancy, as well as up to 50% less power consumption compared to standard dewatering centrifuges.

THK 200“I’m surprised it’s taken this long for other treatment plants to see the value of this piece of equipment. The Kenosha WWTP (Wastewater Treatment Plant) installed our first THK200 in 2011. This one machine replaced four DAFT units, operated 24/7 using no polymer and achieved 5% TS cake and 95% capture. In 2015, we upgraded our plant process and now have an additional THK200 for primary sludge. With this THK, we doubled our solids concentration and cut in half the amount of water sent to the digesters,” said Melissa Arnot, P.E. Director of Operations at Kenosha Water Utility.

The basis of the THK design highlights what Centrisys is best known for – centrifuges. This sludge thickener is not a modified dewatering centrifuge, which is typically what happens when a conventional dewatering centrifuge is used for thickening sludge. The THK sludge thickener is designed and built specifically to thicken both primary and waste activated sludge using the fundamental principles of a centrifuge, DAFT and Rotary Drum Thickener.

According to Centrisys/ CNP’s CEO, Michael Kopper, “Equipment in this industry should last for decades. Those decision makers who understand the increasing importance of lower lifecycle costs and higher process efficiencies are clearly making the right choices for their plants and ultimately rate payers and our environment.”

Centrisys/CNP Announces Exclusive U.S. Distributorship for the Passavant® hydrograv® adapt System

Passavant hydrograv adapt SystemCentrisys/CNP (Kenosha, WI), a leader in decanter centrifuge technology and systems for nutrient recovery and sludge optimization, has announced their exclusive distributorship for the Passavant hydrograv adapt System in North America (U.S. patent pending).

Unlike fixed inlet structures for secondary clarifiers, the Passavant hydrograv adapt System consistently and continuously adjusts to current loading in a clarifier. If the loads are low, the hydrograv adapt automatically shifts the inlet elevation and opening height to a low position, introducing the mixed liquor below the sludge blanket. As the loads increase, the hydrograv adapt system shifts itself to a higher elevation and opening height, ensuring ideal hydraulic conditions for the operation of the secondary clarifiers and avoiding sludge overflow.

Benefits of the Passavant hydrograv adapt System include improved process stability of secondary clarification, a reduction of effluent suspended solids to usually less than 3 mg/L, improved particulate phosphorus removal, improved clarification capacity from hydraulic optimization and overall low maintenance requirements.

At WEFTEC 2018, Dr. Martin Armbruster, the Managing Director and founder of hydrograv GmbH and the inventor of the hydrograv adapt system, will co-present on the topic of “Stress Testing of a Secondary Clarifier with an Adaptive Inlet Structure.” His expertise in the field of clarifier CFD simulation includes optimization and practical engineering for more than 1,000 clarifiers in 200+ treatment plants worldwide. His experience in improving hydraulic efficiency of water management systems is based on 500+ hydrograv® with CFD simulations installations. The seminar will take place on Wednesday, October 3 at 1:50 p.m. in room 239.

Little Patuxent Water Reclamation Facility Upgrades System with AirPrex® for Sludge Optimization and P-Recovery

CNP – Technology Water and Biosolids, a division of Centrisys Corporation in Kenosha, Wisconsin, recently supplied the Howard County Department of Public Works with the patented CNP AirPrex process. AirPrex, scheduled to be operational during the Q3 2018, will improve the current biosolids processing facility by sequestering phosphorous and preventing the formation of phosphorous scale known as struvite.

Howard County Department of Public Works engaged HDR to provide engineering design services for upgrades to the biosolids facilities at the Little Patuxent Water Reclamation Facility in Savage, Maryland. The Little Patuxent facility used dewatered cake lime stabilization for biosolids treatment. The changes to the biosolids processing included eliminating the lime system and replacing it with anaerobic digesters, centrate demmonification and associated solids screening, thickening, odor control and digester gas handling improvements.

After an extensive evaluation of phosphorous removal technologies, the design was based on AirPrex because of its demonstrated ability to prevent struvite precipitation in downstream processes, including piping and the solids dewatering equipment. The Little Patuxent facility uses decanter centrifuges for biosolids dewatering.The AirPrex process is a patented phosphorus recovery technology owned by CNP. AirPrex reduces problematic struvite buildup in wastewater treatment plants improving overall plant efficiencies, including dewatering improvements resulting in significant operational cost savings for treatment plants.

AirPrex’s flexibility was another factor in the design. The process either sequesters struvite, leaving it in the biosolids stream for land application on farm fields as fertilizer, or recovers struvite, separating it from the biosolids stream. Once separated, the struvite can be used as a beneficial slow-release fertilizer.

Howard County selected the Construction Manager at Risk (CMAR) delivery method for the construction of the upgrades and installation of AirPrex. Clark Construction, the CMAR contractor, negotiated with Kershner Environmental Technologies, the local CNP representative, on behalf of the county to procure AirPrex.

The Little Patuxent Water Reclamation Facility is a 29 MGD advanced wastewater treatment plant using enhanced nutrient removal processes to reduce nitrogen and phosphorous discharges to the Chesapeake Bay. The facility serves 56 percent of the county’s 317,000 population.
