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.

研究了三个相互关联的主题，该主题是“从废物流中恢复资源”的总体主题。 （a）磷和氮去除和恢复技术：目标是继续研究并扩展到该申请人，磷（P）和氮（N）清除和从养分 - 丰富的废物中恢复的相对新主题。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 。重点放在“田径”肥料形成，颗粒化和优化的反应器条件上。 （b）先进的废水污泥处理：目的是提高废水污泥处理，重点是嗜热治疗以及过氧化物 - 微波（PM）处理 - 朝着零污泥生产的最终目标。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合并污泥，从上清液中恢复P，TAD系统的挥发性脂肪酸（VFA）的产生，污泥破坏和增强的甲烷生产以产生能量。 （c）处理高氮废物的处理：目的是扩大/扩展研究生物过程的“优化”（固定培养基，Anammox工艺），用于治疗N含N型废水和新的IPPROTED'Ammonia Cracker “技术，使用田径（肥料）颗粒进行烘烤和回收。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。
