Webinar: Case Studies—Struvite Recovery for Phosphorus Removal and Recovery at Wastewater Treatment Plants

December 6th
12:00 pm to 1:30 pm Pacific Time

Sponsored by PNCWA Emerging Technology Committee
No cost for PNCWA members, PNCWA Section members, and WEF-UPP organization employees; .1 CEUs requested; $50 for nonmembers

Struvite, or magnesium ammonium phosphate, is a crystalline material that is often formed downstream of anaerobic digestion processes, where abundant nitrogen, magnesium, and phosphorus is present and pH is raised due to CO2 stripping, which results from pumping or other turbulences. Uncontrolled struvite formation is typically viewed as a maintenance problem; until recently, as technologies have emerged that precipitate struvite in a controlled manner to recover phosphorus, allowing the plants to achieve low phosphorus limits, and simultaneously remove a fraction of the sidestream nitrogen.

This webinar highlights and provides the updates on full-scale implementations of two representative struvite recovery technologies in the Pacific Northwest, the Ostara Nutrient Recovery Technology implemented at the Clean Water Services’ wastewater treatment facilities (WWTFs) in Oregon, and the Multiform P- Recovery System implemented at the West Boise WWTF of City of Boise, Idaho.

This webinar completes the side stream webinar series started in 2015.

This webinar features the following presentations:

  • Case studies: Struvite Recovery at Durham and Rock Creek Wastewater Treatment Facilities (WWTF), OR, by Peter Schauer, Clean Water Services, OR. The presentation will discuss the history of the first struvite recovery facility in United States that was opened at the Durham WWTF in 2009, and the struvite recovery facility opened in 2012 at the Rock Creek WWTF. Updates on the recent operations will be provided.
  • Case study: Struvite Recovery at West Boise WWTF, ID, by William Benko and Ron Gearhart, City of Boise, ID. The West Boise WWTF dewaters digested sludge from the nearby Launder Street WWTF, which represents a significant phosphorus load to the West Boise WWTF. The presentation will highlight the latest operational requirements and optimization of the struvite production facility and the impacts from the 2015 startup of the enhanced biological phosphorus removal (EBPR) improvements constructed at the West Boise WWTF, as well as from Launder Street WWTF’s 2015 conversion from a chemical phosphorus removal plant to an EBPR plant.


This webinar is ideal for municipalities, utility managers, operators, and engineers who may consider or be interested in utilizing struvite recovery as a potential revenue generating vehicle to recover phosphorus, reduce sidestream phosphorus load to the plant, and allow achievement of stringent phosphorus permit limit more efficiently.

Past Webinars

  • Asset Management - CMMS Aug. 11, 2016

  • Significant money is spent collecting data for utility operations, capital improvement, and customer service. But many utilities do not know what happens to data after it is collected. Do operations improve or does the data sit, under-analyzed, on utility servers? The more resources we place in collecting data, the more important it becomes to know that we are actually using that data to improve our decision making.

    • This webinar highlights the essential methods for using data effectively. Participants will learn how to optimally choose key performance indicators and run the right reports. They will take away optimized data visualization techniques and better understand how to leverage their technology to make decisions.

    • This webinar is ideal for utility managers and operators who want to better leverage utility data collection to improve processes, management, and customer service.

  • Cyber Security for WWTP Operations and Maintenance Aug. 23, 2016 

  • Cyber-Security is an ever-increasing concern for governments, businesses, and consumers. High-profile data breaches that affect government agencies, conglomerates and millions of consumers alike indicate hackers are becoming more creative in their efforts. Historically, SCADA systems have been isolated from cyber-attacks; primarily because SCADA systems were developed in isolation of business networks. As critical infrastructures such as water systems become increasingly dependent on digital technology, those that manage these systems must be educated in the ways that computers and networks influence their operation.

    • This webinar will review the range of security technologies used to protect those systems including case studies, and will cover methods and processes that do allow for legitimate stakeholder access to data and yet provide adequate security to identify and minimize the impacts of cyber-attacks.

Webinar Continuing Education Units Requirements

The following guidelines apply when a webinar is approved for CEU’s

  • No partial credit will be given.
  • Attendees must pre-register and provide a valid certification number or License number.
  • Each attendee must be logged into a separate computer so that their participation may be accurately tracked.
  • In certain webinars where the CEU authority has required a proctor or attendance monitor be present, more than one individual may attend at a station and be eligible for CEUs.
