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.

能源资源的枯竭、世界范围内能源需求的增加以及主要由矿物燃料的人为活动引起的全球气候变化都可能对经济发展有害，特别是在诸如北美这样的高能量消费地区。长期以来，废水一直被认为是一个人类健康问题和环境危害，因此，经过处理，产生的废水质量令人满意，可以排放到环境中。为了促进水资源回收设施（WRRFs）的发展，目前正在进行从将废水流视为废物到将其视为主动能源和物质资源的范式转变。拟议研究计划的总体目标是开发经济，稳健和高效的工艺来生产生物能源和从废水中回收化学资源，并将高强度有机城市废物流转化为WRRFs设施，从中回收水和不同的增值产品。该研究计划将重点放在已开发技术的调试和下一组增值产品上，主要关注废水中的高风险化合物，并研究这些生物技术来去除废水中最近发现的污染物。这将涉及四个研究主题：1)探索对传统活性污泥工艺的改进，并将其转化为高速率活性污泥（a - hras）、高速率接触稳定（HiCS）和交替活性吸附（AAA）的a级工艺；2)开发从废物流中回收生物甲醇、细胞外聚合物（EPS）和生物聚合物（PHB和pha）的顺序生化工艺；3)开发一种将改性活性污泥系统与顺序生化过程集成的新方法；4)开发一个高级模型，将新系统集成到WRRFs过程和真实的城市废物流中。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生产更多的能源和化学品，利用最新的技术进步。此外，加拿大需要培养能够开发和操作这些流程的高素质研究人员/工程师。对于安大略省来说，从环境和社会的角度来看，强烈建议将废水作为资源和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的生物技术来生产/回收能源、资源和增值产品。这些生物技术的新颖性不仅在于它整合了100%由加拿大研究人员和专业工程师开发的创新技术，而且每一项技术都提出了解决实际问题的新方法，并推动了最先进的技术。
