Centrisys secured an order from the City of Manchester, New Hampshire for the Department of Public Works–Environmental Protection Division's Solids Train Project for three THK350 sewage sludge thickeners and upgrades to all existing decanter centrifuge control panels. The THKs will eliminate the release of phosphorus. The captured phosphorus will be maintained in the biosolids; this plays a critical role in meeting the city's P effluent permit. All units will be designed, engineered, and built in the United States, with centrifuge shipment expected in November 2021.

Centrisys’ is providing five custom CS30-4DT dewatering centrifuges and one spare rotating assembly for the upgrade and expansion at Inland Empire Utilities' Regional Water Recycling Plant No. 5 in Chino, California. The project will expand the biosolids managment system to 40 MGD, including thickening, anaerobic digestion and dewatering, and potential food waste treatment. Centrisys was selected as the centrifuge of choice between four centrifuge manufacturers based on Centrisys' ability to provide custom centrifuges to meet the specific demands of the application.
The City of Seaside, Oregon Wastewater Treatment Plant solids handling upgrade will include a DLT420 low-temperature sludge belt dryer specifically designed and manufactured for the U.S. WWTP and a CS21-4HC dewatering centrifuge. The upgraded equipment replaces aging dewatering and sludge drying equipment and allows the city to meet the Western Oregon regulation that mandates the elimination of Class B cake in landfills. The DLT dryer meets Class A requirements, produces a sludge with a dryness level greater than 90% solids and reduces biosoilds weight up to +80%. The DLT uses standard USA parts and components that are manufactured, sourced and distributed in the USA, ensuring that the DLT is USA BABA manufacturing compliant.

New BioWin processes were created to model organic acid phase digestion and brushite precipitation and recovery. Several BioWin default parameters for those process compartments were optimized against the extensive published data from the WRF-sponsored 2018 pilot at Nine Springs Wastewater Treatment Plant, Madison, WI, and correctly model pH and concentrations of VFAs and soluble P in the organic digester and brushite collection from the CalPrex pilot operation. BioWin modeling predicts brushite recovery levels at whole-plant scale as the sole P recovery technology and permits comparison with the existing struvite recovery process in place. Economic analysis shows that brushite recovered at a WWTP with an existing acid digester is cost-competitive with standard P fertilizers, even without considering the value of nuisance struvite reduction.
PONDUS is designed for solids from 4% to 12% and uses a combination of caustic soda (NaOH) and low grade heated water (140 °F to 160 °F) to break down the cell walls. It is a cost-effective choice that requires little day-to-day plant supervision or pressure vessel. Because of PONDUS' simplicity and long-time operational success, two more projects are underway in Germany and two PONDUS orders are pending in the USA.

The Fox River Water Reclamation District (FRWRD) MagPrex system has been operating since 2021 and is close to full Bio-P. MagPrex removes at least 90% of the soluble phosphorus concentrations in the anaerobically digested biosoilds and ensures FRWRD meets their stringent P-limits and mitigates any P-related operational or maintenance issues. Central Valley Water Reclamation Facility has almost completed the MagPrex construction and will start up in Q1 of 2023; Meridian Wastewater Plant's MagPrex system is in fabrication; and Nampa Wastewater Treatment Plant's MagPrex system is in design.

The Build America, Buy America (BABA) Act went into effect, but changes to the Act’s requirements are expected to be put into place by Fall 2022. This impacts businesses and the manufacturing and buying/selling of goods as the Act calls for 55% of all iron, steel, manufactured products, and construction materials to be domestically produced for a project to receive and use federal funding.
Do Centrisys/CNP’s sourcing and manufacturing practices comply with BABA requirements?
Yes. Centrisys/CNP will work collaboratively to ensure all sourcing and manufacturing practices comply with the BABA requirements currently in place for any municipal or industrial customers.
