Centrisys to provide centrifuges for Inland Empire Utilities Plant expansion in Chino, CA

Centrisys Corporation has announced that it has secured an order from Inland Empire Utilities to support a planned upgrade and expansion of its Regional Water Recycling Plant No. 5 (RP-5) in Chino, California. With plant upgrade and expansion design and engineering support provided by Parsons, the order placed with Centrisys consists of five custom CS30-4DT decanter centrifuges and one spare rotating assembly unit. All units will be designed, engineered, and built in the United States with shipment and installation planned to take place in July 2022.

“The Centrisys team was thrilled to offer the customised solution required by Inland Empire Utilities and Parsons’ engineer to meet specific application requirements,” said Michael Kopper, president and chief executive officer of Centrisys. “The Centrisys CS30-4DT offers the highest G-volume of any other competing centrifuges, and our customisation options create a robust option for the specified feed application. Even with the customised centrifuge features, we know our capabilities will allow us to meet or exceed delivery date guidelines.”

The Centrisys CS30-4DT decanter centrifuge offers:

  • Feed capacity up to 600gpm
  • Design flow for maximum removal efficiency up to 380gpm
  • Total installed power of 190HP
  • Air/oil auto lube system 

The RP-5 upgrade and expansion will increase liquid treatment to 30 million gallons per day (mgd) using membrane bioreactor (MBR) and ultraviolet (UV) disinfection processes, and will expand the biosolids management system to 40 mgd, including thickening, anaerobic digestion and dewatering, and potential food waste treatment. The increased biosolids treatment capacity at RP-5 will replace Regional Water Recycling Plant 2, allowing that facility to be decommissioned.

As one of the nation’s largest recycled water facilities using membrane bioreactor and ultraviolet disinfection, the upgrade and expansion to RP-5 will support groundwater recharge and a reduction of the region’s need for imported water. Additionally, as expanded landfill restrictions and food disposal laws go into effect in California, the facility will eventually accommodate food waste digestion.
