Meeting Zero Liquid Discharge Goals at Simplot Potato Plant
Demand is trending upward for one of the world’s largest producers of potato products. The J.R. Simplot Company (Simplot) has seen steady growth in its French fry and potato product business in recent years. To meet that growth and increase efficiency, Simplot expanded by building a new, large production facility in Caldwell, Idaho. Inspired by its core values of respect for resources, spirit of innovation and passion for people, the company set ambitious zero discharge water management objectives for the new facility. Simplot then enlisted CDM Smith to design and build a process water treatment system that would accomplish the company’s goals of discharging no water to local streams or city sewers and producing treated return water suitable for reuse in the food production process.
The project’s completion marks Simplot’s designation as the largest food processor successfully returning treated process water equivalent to EPA drinking water standards in the United States. And due to its successful execution and collaborative partnership, Simplot’s PWTRP was named the national 2016 Industrial Project of the Year by the WateReuse Association. The facility was later honored as Food Processing magazine's 2017 Green Plant of the Year.
