Three interrelated topics are being researched, on the overall theme of "resource recovery from waste streams".(a) Phosphorus and Nitrogen Removal and Recovery Technology: The objective is to continue and expand on research into a relatively new topic for this applicant, phosphorus (P) and nitrogen (N) removal and recovery from nutrient - rich wastes. Facilities include lab-scale, pilot scale and commercial-scale up flow reactor systems, installed at UBC, the Dairy Education Research Centre (DERC) at Agassiz, B.C., and at the new Annacis Wastewater Centre (AWC), Metro Vancouver Annacis, WWTP. The focus is on "struvite" fertilizer formation, pelletization and optimized reactor conditions.(b) Advanced Waste-Water Sludge Treatment: The objective is to advance waste-water sludge treatment, with an emphasis on thermophilic treatment, as well as peroxide-microwave (PM) treatment - toward the ultimate goal of zero-sludge production. Facilities include an advanced biological nutrient removal (BNR) pilot plant, a pilot scale PM system and a thermophilic sludge treatment facility (TAD) in Salmon Arm, B.C. Current research is focused on treatment of combined sludges, recovery of P from digester supernatant, production of volatile fatty acids (VFA) from TAD systems, sludge destruction and enhanced methane production for energy generation.(c) Treatment of High Nitrogen Wastes: The objective is to expand/scale-up research on "optimization" of biological processes (fixed media, Anammox process) chosen for treatment of N-laden wastwaters and a new IP-protected "ammonia cracker" technology, using struvite (fertilizer) pellets for roasting and recycling. The emphasis continues to be on nutrient-recovery, energy production, and toxicity reduction of final effluent discharges.

正在研究三个相互关联的主题，这是“从废物流中回收的资源回收”的总体主题。（a）磷和氮去除和恢复技术：目标是继续研究并将研究扩展到该申请人相对较新的话题中（p）和氮（n）从养分 - 富含营养的废物中恢复。设施包括实验室规模，飞行员量表和商业规模的流动反应堆系统，该系统安装在UBC，卑诗省阿加西兹的乳制品教育研究中心（DERC）以及新的Annacis Wastewater Center（AW​​C），温哥华Annacis，WWTP，WWTP 。重点是“田径”肥料形成，颗粒化和优化的反应堆条件。（b）先进的废水污泥处理：目标是提高废水污泥处理，重点是嗜热治疗以及过氧化物 - 微波处理（PM）治疗 - 朝着零污染生产的最终目标。设施包括先进的生物营养素清除（BNR）试验厂，试点量表PM系统和卑诗省鲑鱼臂中的嗜热污泥处理设施（TAD）。当前的研究集中在治疗污泥的处理，从上清液中回收P，tad系统中挥发性脂肪酸（VFA）的产生，污泥破坏和甲烷产生增强的能量产生。是为了扩展/扩展对生物过程“优化”（固定培养基，Anammox工艺）的研究，用于治疗N含N型废水和一种新的受ip蛋白质保护的“ Ammonia Cracker”技术和回收。这种重点继续是养分恢复，能源生产和最终废水排放的毒性降低。
