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）由联邦和省级法规授权升级，以完全去除导致河流和湖泊恶化的有机物和有害营养物。现有的污水处理厂使用长的连续流反应器（CFR）。对这些工厂进行传统的升级将需要大量增加土地（通常现场几乎没有）和资本成本，并带来巨大的运营成本，这对一个市政当局来说可能是压倒性的。一种新的和高效的好氧颗粒污泥（AGS）技术，最近在加拿大以外的地方展示，有可能抵消这些问题，需要更少的土地和携带低得多的运营成本。 然而，AGS技术仅作为序批式反应器技术或AGS-SBR提供，这是一种不连续的工艺，不适合于改造/升级加拿大90%的市政工厂中存在的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，其配置将以现有连续流系统中颗粒污泥的关键要素为特征。在现有的污水处理厂，将使用一个大型的试验规模的系统，以原料污水进料，以制定设计标准，控制，监测和操作参数，这将有助于扩大到全规模。这种突破性的新AGS CFR方法的要素已经由申请人在小规模中证明。 该项目对加拿大各城市具有战略重要性，因为AGS-CFR的应用将允许通过将该过程融入现有基础设施并实际降低运营成本来实施全面的营养物去除。 工业合作伙伴AECOM对在其全球设计工作中采用该技术有着直接的兴趣。温尼伯市公用事业合作伙伴对此非常感兴趣，因为它一直面临着高昂的成本和预期的主工厂常规升级规模，因此将AGS-CFR技术视为实现更实惠的资本和运营成本的替代解决方案。**
