Depleted energy resources, increasing worldwide energy demand, and global climate change, mainly caused by anthropogenic activities of fossil fuels can be detrimental to economic development, particularly in areas of high-energy consumption such as North America. For a long time, wastewater has been considered a human health concern and an environmental hazard and therefore, treated to produce an effluent with satisfactory quality for discharge to the environment. A paradigm shift from considering wastewater streams as waste to being treated as a proactive energy and material resource is currently underway to contribute to the development of water resource recovery facilities (WRRFs). The overall objective of the proposed research program is to develop economical, robust, and efficient processes to produce bioenergy and recover chemical resources from wastewater and turn the high strength organic municipal waste streams into WRRFs facilities from which water along with different value-added products can be recovered. The research program will be focusing on the commissioning of the developed technologies and the next group of value-added products with a main focus on the high-risk compound in the wastewater and study of these biotechnologies to remove pollutants that recently discovered their presence in the wastewater. This will be done across four research themes: 1) Explore the modification of conventional activated sludge process and convert it into an A-stage process of high rate activated sludge (A-HRAS), high-rate contact stabilization (HiCS), and Alternating Activated Adsorption (AAA), 2) Develop a sequential biochemical process to recover biomethanol, extracellular polymeric substances (EPS), and Biopolymer (PHB and PHAs) from waste streams, 3) Develop a novel approach to integrate the Modified activated sludge system with the sequential biochemical process, and 4) Develop a high-level model to integrate the new systems within the WRRFs process and real municipal waste streams. For future sustainability, Canada needs to produce more of its energy and chemicals using a process based on renewable materials that utilize the latest advances in technology. Furthermore, Canada needs to train highly qualified researchers/engineers that can develop and operate these processes. For Ontario, creating and using wastewater as recourses and recovery into valuable resources substitute is strongly recommended from environmental and societal perspectives. Hence, an essential part of that future will rely on using innovative biotechnology to produce/recover energy, resources, and value-added products. The novelty of these biotechnologies not only lies in its integration of innovative technologies that are being developed by 100% Canadian researchers and professional engineers, but also every technology presents a novel approach to resolve a practical problem, and advances the state-of-the-art.

主要由化石燃料的人类活动引起的能源资源枯竭、全球能源需求增加以及全球气候变化可能对经济发展有害，特别是在北美等高能耗地区。长期以来，废水一直被认为是人类健康问题和环境危害，因此被处理以产生具有令人满意的质量的流出物以排放到环境中。目前正在进行从将废水流视为废物到将其视为积极的能源和物质资源的范式转变，以促进水资源回收设施（WRRF）的发展。拟议的研究计划的总体目标是开发经济，稳健，高效的工艺，以生产生物能源和回收废水中的化学资源，并把高强度的有机城市废物流到WRFs设施，水沿着不同的增值产品可以回收。该研究计划将专注于开发技术和下一组增值产品的调试，主要关注废水中的高风险化合物，并研究这些生物技术以去除最近发现的废水中存在的污染物。这将在四个研究主题中进行：1）探索传统活性污泥法的改造，将其改造为高速率活性污泥（A-HRAS）、高速率接触稳定（HiCS）和交替活性吸附（AAA）的A级工艺; 2）开发回收生物甲醇、胞外聚合物（EPS）、和生物聚合物（聚羟基丁酸和PHA）的废物流，3）开发一种新的方法，以整合的改性活性污泥系统与连续的生化过程，和4）开发一个高层次的模型，以整合新的系统内的WRRF过程和真实的城市废物流。 为了未来的可持续发展，加拿大需要使用基于可再生材料的工艺来生产更多的能源和化学品，这些材料利用了最新的技术进步。此外，加拿大需要培训能够开发和操作这些工艺的高素质研究人员/工程师。对于安大略来说，从环境和社会的角度来看，强烈建议将废水作为资源并回收为有价值的资源替代品。因此，未来的一个重要部分将依赖于使用创新生物技术来生产/回收能源、资源和增值产品。这些生物技术的新奇不仅在于它整合了由100%加拿大研究人员和专业工程师开发的创新技术，而且每项技术都提出了解决实际问题的新方法，并推进了最先进的技术。
