Biosolids and Composting Technical Tour

Three distinct tours have been organized to enhance the learning opportunities for attendees at the 2015 BCWWA Annual Conference & Trade Show. This tour showcases the City of Kelowna Wastewater Treatment Plant and the Okanagan College Wastewater Heat Recovery process.

Tour Details

Date: Wednesday May 27, 2015
Time:  12:00 - 4:30pm
Location:  Bus departs from The Delta Grand Okanagan Hotel at the North Entrance
Price:  Registration closed
CEUs: 0.15

This tour includes bus transportation to and from the tour sites, and a boxed lunch.

The first part of this tour shows attendees the lab and an overview of the work of Dr. Eskicioglu and her research team at the University of British Columbia’s Okanagan Biosolids Lab are conducting.  Dr. Eskicioglu and her research team have established the UBC Bioreactor Technology Group that is operating three state-of-the-art laboratory facilities (i.e. Advanced Anaerobic Digestion Facility, Particle Sizing, Zeta Potential and Imaging Facility and Micro-pollutant Detection Facility) at the University of BC’s Okanagan Campus.

Attendees will learn about how the group is working toward gaining greater understanding of biological waste treatment processes and developing new bioreactor technologies for maximizing energy (biogas) and resource recovery from organic waste (i.e. municipal and industrial biosolids, kitchen waste, animal manure).

Other areas of interest the group is working on include:

  • Producing digested biosolids in compliance with the Organic Matter Recycling (OMR) and Food Inspection Agency (CFIA).
  • Fertilizer regulations (concerning pathogenic microorganisms and heavy metals) for reuse as soil amendment.
  • Detection of odors and micropollutants of emerging concern (i.e. hormones, pharmaceutical and personal care products) in wastewater and biosolids.

The second part of the tour takes place at the Regional Biosolids Composting Facility operated by the City of Kelowna. In 2006, the City of Kelowna and the City of Vernon began operation of a Regional Biosolids Composting Facility (RBCF) utilizing the Extended Aerated Static Pile technology to process 27000 wet tonnes of dewatered biosolids annually (18-20% solids). The highly advanced composting technology produces a high quality compost product (Ogogrow) that is primarily sold to nurseries, landscapers, home gardeners and one value added customer.

Tour attendees will learn about the challenges and lessons learned in composting biosolids in an arid environment, as well as issues around odour generation, monitoring and control, and leachate management.
