City of Spokane selects Pall filtration technology for water reuse project

Pall Corp is to provide membrane filtration for the City of Spokane’s Riverside Park Water Reclamation Facility upgrade in Washington, USA.

After a successful year-long, head to head pilot against submerged membrane technology conducted by CH2M, the Pall Aria™ FLEX system was selected based on significantly lower cost of operations.

“While both systems clearly achieved the phosphorous removal limit, the Pall offering allows us to meet our treatment goals in an easy to use system,” said Mike Taylor, Next Level of Treatment Program Manager, City of Spokane. “After a rigorous qualitative and quantitative evaluation of both offerings, the Pall system was our first choice. We are excited to work with the Pall team and look forward to achieving our Cleaner River Faster goal.”
 
The Aria FLEX system was designed to treat a maximum monthly average wastewater flow of 50 million gallons per day (MGD) and a 12-hour peak flow of 75 MGD. The custom system is engineered to successfully treat seasonal algae and other unique characteristics of wastewater that is discharged into Spokane River.
 
A member of Pall’s Aria CARE service team will be onsite for support during the first year.
 
This project will be the largest upgrade at the plant, which currently treats 34 MGD.
 
The use of Pall filtration units at the Riverside Park Water Reclamation Facility is part of the City of Spokane’s Integrated Clean Water Plan which is a major, multi-year initiative aimed at improving the health of the Spokane River.
