Operations Support at Scottsdale Water Campus Advanced Water Treatment Facility

Client: City of Scottsdale
Location: Scottsdale, Arizona

Hazen provided operations support including process performance troubleshooting and procurement assistance for large diameter reverse osmosis membranes, developing clean-in-place standard operating procedures, procurement and acceptance testing of new antiscalant, and evaluation for rehabilitation or replacement of pretreatment strainers.

Our operations support included process performance troubleshooting and procurement assistance for large diameter reverse osmosis membranes.

With an overall plant capacity of 20 mgd, the plant has a combination of RO trains using 8” diameter membrane elements and RO trains using 16” diameter membrane elements.

The Scottsdale Water Campus in Arizona is an innovative water reuse facility, using microfiltration, reverse osmosis (RO), and ultraviolet (UV) treatment processes to recycle tertiary effluent for a variety of reuse applications, including golf course irrigation and aquifer recharge.

Since beginning operation in 1999, the facility has reclaimed more than 19 bil gal of wastewater for aquifer recharge and golf course irrigation.

Project Outcomes and Benefits

  • Deliverable output for large diameter reverse osmosis performance evaluation and troubleshooting was a report on all findings and recommendations.
  • Subsequently, Hazen was contracted to assist with implementing recommended actions, including procurement of new membranes and standard operating procedure development.
  • Hazen was also contracted to assist with strainer evaluation for rehabilitation or replacement and antiscalant procurement and acceptance testing.
