Centrisys/CNP to upgrade Houston wastewater treatment plant

Decanter centrifuge manufacturer Centrisys/CNP is to upgrade equipment for the City of Houston’s largest wastewater treatment facility - the 69th Street Wastewater Treatment Plant – in Texas, USA.

The upgrade will include 14 CS21-4HC 2ph decanter centrifuges with two spare rotating assemblies.

The new equipment will replace aging dewatering and solids handling equipment and will support the facility’s management of up to 200 million gallons per day (MGD) and daily average flow of 400 MGD 2-hour peak flow.

Houston’s 69th Street Wastewater Treatment Plant currently consists of 21 decanter centrifuges separated into seven trains. Each train is equipped with two duty decanter centrifuges and one standby. The upgrade will allow for the replacement of existing decanter centrifuges, continuing the use of two decanter centrifuges per train, with two backup decanter centrifuges stored onsite.

Global WET, Centrisys/CNP’s manufacturing representative based in Austin, Texas, assisted with the project in the planning of technology to advance Houston’s 69th Street Wastewater Treatment Plant’s infrastructure and performance.

“In collaboration with Global WET, a thorough assessment was conducted during the bidding phase to ensure the wastewater treatment plant would get the most optimal equipment to achieve its goals,” said Josh Gable, sales director for Centrisys/CNP. “It is a critical first step when municipal plant representatives understand the process and importance of a bid evaluation and take the costs associated with maintenance and spare parts availability - not only CAPEX - into close consideration. We’re proud that Centrisys/CNP shines bright for the quality and reliability of our equipment and technology, as well as parts availability, service, and support.”

In October 2022, Centrisys/CNP announced the planned opening of a new service and repair centre in Houston, Texas, to support customers located throughout the south-central region of the US. The facility opened in January 2023 and will offer full-service repair and maintenance capabilities, including inspections, machining, welding and balancing. Onsite technicians will also have the capability to test equipment and manufacture spare parts all under one roof, with quality control capabilities for all brands of decanter centrifuges.
