Water is a precious resource, and nowhere is that more evident than places like Chandler, Arizona, where demand for water is high, but supply can be precariously low. That’s why a global semiconductor manufacturer chose the design-build team of Sundt and our design partner to come up with a solution to treat a wastewater stream from its newest fabrication facility. The team developed a treatment solution that significantly reduced the volume of brine flow through a combination of pretreatment, desalination, and thermal concentration technologies.
This state-of-the-art, unique system creates an extremely high quality water product that has a wide variety of potential uses to offset our client’s potable water demands. The brine reduction facility was designed to treat 1,950 gallons of wastewater per minute. Approximately 97 percent of the water that comes into the plant is being re-used or re-injected, instead of going to waste. Reducing the waste stream from nearly 2,000 gallons per minute to less than 60 was a significant achievement.
The unique combination of technologies used to produce such a high level of treatment is extremely cutting-edge and possibly the first of its kind.
Recovering and reusing a high percentage of the water from the fabrication facility, or squeezing more usable water out of the waste stream, helps manage the City of Chandler’s water resource issues and will provide opportunities for additional economic development and sustainable growth.
