Canada's wastewater treatment plants (WWTP) are mandated by federal and provincial regulations to upgrade to full removal of organics and fertilizing nutrients which lead to deterioration of rivers and lakes. Existing WWTP use long, continuous flow reactors (CFR). A traditional upgrade of such plants would require significant increase of land (often hardly available on site) and capital costs as well as carry large operating costs, which could be overwhelming for a municipality. A new and highly effective technology of aerobic granular sludge (AGS) recently demonstrated outside Canada, has potential to offset these problems by requiring less land and carrying much lower operating costs. The AGS technology is however offered only as a sequencing batch reactor technology or AGS-SBR, which is a discontinuous process and is ill-suited to retrofit/upgrade the CFR process present in some 90% of Canadian municipal plants. It is proposed to develop a ground-breaking aerobic granular sludge continuous flow reactor or AGS-CFR, in a configuration that would feature key elements of granular sludge in an existing continuous flow system. A large pilot scale system fed with raw wastewater at an existing wastewater treatment plant will be used to develop design criteria, control, monitoring and operational parameters which will facilitate scale-up to full scale. The elements of this breakthrough new AGS CFR process have already been demonstrated by the Applicants in small scale. The project is of strategic importance to Canadian municipalities as application of AGS-CFR will allow for implementation of full nutrient removal by fitting the process into existing infrastructure and actually lowering the operating costs. The industrial partner AECOM has an immediate interest in adopting the technology in its design work around the world. The City of Winnipeg utility partner is vitally interested as it has been faced with prohibitive costs and size of anticipated conventional upgrade of its main plant and therefore views the AGS-CFR technology as the alternative solution to arrive at more affordable capital and operating costs.**

加拿大的废水处理厂（WWTP）根据联邦和省级法规的要求进行升级，以完全去除导致河流和湖泊恶化的有机物和施肥养分。现有污水处理厂使用长的连续流反应器 (CFR)。此类工厂的传统升级将需要大量增加土地（通常现场很难获得）和资本成本，并且会带来巨额运营成本，这对于市政当局来说可能是难以承受的。最近在加拿大境外展示了一种高效的新的好氧颗粒污泥（AGS）技术，该技术有可能通过减少土地需求和降低运营成本来解决这些问题。 然而，AGS 技术仅作为序批式反应器技术或 AGS-SBR 提供，这是一种不连续工艺，不适合改造/升级加拿大约 90% 市政工厂中存在的 CFR 工艺。 建议开发一种突破性的好氧颗粒污泥连续流反应器或 AGS-CFR，其配置将具有现有连续流系统中颗粒污泥的关键要素。将使用现有废水处理厂的一个大型中试规模系统，以原废水为原料，制定设计标准、控制、监测和操作参数，以促进全面扩大规模。申请人已经小规模地演示了这一突破性的新AGS CFR工艺的要素。 该项目对加拿大市政当局具有战略意义，因为 AGS-CFR 的应用将允许通过将该工艺融入现有基础设施并实际降低运营成本来实现全面的营养物去除。 工业合作伙伴 AECOM 非常有兴趣在其世界各地的设计工作中采用该技术。温尼伯市公用事业合作伙伴对此非常感兴趣，因为其主电厂的预期常规升级成本高昂且规模庞大，因此将 AGS-CFR 技术视为替代解决方案，以实现更实惠的资本和运营成本。* *
