Advanced Resource Recovery from Sludgehttps://metrovancouver.org/about-us/sustainability-innovation-fund/project/34Advanced Resource Recovery from SludgeWaste management;Resource recoveryIn Progress<div class="ExternalClass405E5719EA184087ADFDECF384C5C241"><p>Advancing the recovery of resources from wastewater to produce value-added outputs for use by other industries can help build a stronger circular economy. The project goals are to (i) assess options for recycling the HTP aqueous effluent back to the WWTP, explore the potential for recovering nitrogen and phosphorus from HTP by-products, evaluate the destruction of CECs in HTP; and (ii) develop a bioreactor that can augment production of biomethane from sludge.</p><p>The project partners are UBC School of Engineering and the Natural Sciences and Engineering Research Council.</p><p>An additional $1.83 million in funding has been leveraged from external agencies for this project.<br></p></div><div class="ExternalClassD5978EFE58384E9FBDDEF7FBF4472E56"><p> <strong>(i) </strong><br> Tested several treatment processes for the HTP aqueous stream and identified severalpromising options, as well as their limitations.</p><p>Investigated options to recover nutrients from HTP byproducts –​ namely ammonia from the aqueous stream and phosphorus from the solid precipitate – in forms that could be beneficially used as fertilizer.</p><p>Explored the fate of CECs in HTP.</p><p>Disseminated research results in eighteen journal articles and eleven conference presentations.</p><p> <strong>(ii) </strong><br>The UBC team’s prototyping guided the transition of the bioreactor project from lab scale topilot scale. An engineering consultant completed preliminary design for a pilot-scale bioreactor to be tested at Lulu Island WWTP.</p><p> <strong>Next steps</strong></p><p> <strong>(i) </strong><br>Research will be conducted on adding fats, oils, and grease (FOG) to the wastewater sludgefeedstock for HTP. The results of UBC’s research will inform the operation of the HTP demonstrationfacility at Annacis Island WWTP, as well as informing integration of HTP into WWTPs in future full-scale implementation. The research will also inform pathways for recovering nutrients from HTP by-products th​at can contribute to the business case for full-scale HTP.</p><p> <strong>(ii) </strong><br>The pilot-scale bioreactor will be constructed and the pilot test results will be evaluated todetermine the increase in biomethane production. The business case will be updated to inform whether to proceed with full-scale implementation at a Metro Vancouver WWTP.</p>​<br></div>GP0|#dc483649-e413-4696-af50-020fd4b8c1eb;L0|#0dc483649-e413-4696-af50-020fd4b8c1eb|Liquid Waste;GTSet|#ab8a80a3-ac09-4cde-99c1-454c04cb5931BC Lower Mainland2019
