Industrial Wastewater Treatment and Recovery Plant Design-Build for a Semiconductor Facility

Carollo delivered programming, detailed design, and engineering support during construction services for an industrial wastewater treatment and recovery plant owned and operated by a confidential semiconductor manufacturing facility in the City of Chandler, Arizona. The client’s top priority for this design was meeting stringent water quality goals while ensuring that treated reclaimed water was available to serve their on-site factories around the clock.

Carollo designed the plant’s treatment train to accomplish three primary tasks:

• Reduce total nitrogen (TN): Achieved through equalization and peroxide quench, biological nutrient removal (BNR), and membrane bioreactor (MBR) processes. Biosolids are stored on-site, dewatered through a screw press, and hauled to the local landfill.
• Concentrate total dissolved solids (TDS): Achieved through ion exchange, reverse osmosis, and thermal concentration using bring concentrators and crystallizers. Reclaimed water is stored on-site and re-used for factory operations.
• Remove TDS: Achieved through brine storage and salt handling before the end product is hauled off-site to the local landfill.

The plant also features odor control, chemical storage, and an administration building.

In addition to coordinating with the pre-selected supplier, contractor, and the client to install these various process systems, Carollo also worked closely with the Maricopa County Environmental Services Department to obtain permit approval for this important design-build project.
