The objective of this research is to develop new devises which will enhance electrokinetically generation of energy from sludge and wastewater, while a high quality effluent is simultaneously produced. The project might be seen not only as a part of new self-sustained environmental engineering facilities with zero-energy and zero-emission-waste systems, but rather as a source of value added products. Subsequently, the project focuses on development anaerobic electro-bioreactors with and without membranes. Proposed investigations will also combine the anaerobic electro-bioreactor with principles of microbial electrolysis cells, which is a superior of all conventional bio-electrochemical system. Energy will be obtained based on a sustainable process combining biological processes, electrokinetic phenomena, exothermic reactions, and membrane filtration. Developed technologies, beside generation of energy, they will produce recycle water and excellent quality soil amendment. Work defined in Stream 1 will address superior production of biogas from solids streams (biological sludge with/without additional load of fat, oil and grease). The methodological approach will permit to increase the efficiency of biotic and abiotic gas production by application of enhanced electrokinetics to organic solids, while vastly improving the final quality of electro-anaerobically treated sludge and effluents. Work defined in Stream 2 will focus on hydrogen-biohydrogen production from wastewater by novel anaerobic membrane electro-bioreactor. The project addresses issues important to Canada and the world; i.e. production of clean energy and preserving clean water resources. Many municipalities and industries are seeking more sustainable treatment of their wastewater with lower costs and utilizing novel forms of energy recovery. It is anticipated that developed system would be also serve decentralized treatment systems, mining and military bases, as well as remote located settlements, even in northern regions. The validation of devises in cold temperature is considered. New technologies would improve the quality of life in many areas where sanitation and energy are still insufficient. The success of the project will also lay on advanced investigations of microbial communities undergone changes in anaerobic digester under electrical field - significant contributions to science are expected. The project will permit to train at least 15 HQP - leaders in advanced treatment of wasted materials and energy recovery. Due to multidisciplinary research team, HQP will be exposed to different domains of science which permit them to become more knowledgeable, creative and competitive.

这项研究的目的是开发新的装置，以加强从污泥和废水中电动产生能量，同时产生高质量的废水。该项目不仅可以被视为具有零能源和零排放废物系统的自给自足的新环境工程设施的一部分，而且还可以被视为增值产品的来源。随后，该项目的重点是开发带膜和不带膜的厌氧电生物反应器。拟议的研究还将厌氧电生物反应器与微生物电解池的原理相结合，这是所有传统生物电化学系统的优势。能源将基于生物过程、电动现象、放热反应和膜过滤的可持续过程而获得。先进的技术，除了发电外，还将生产循环水和优质的土壤改良剂。流1中定义的工作将解决固体流(含/不含额外脂肪、油和油脂的生物污泥)生产沼气的优势。该方法将允许通过将增强的电动力学应用于有机固体来提高生物和非生物气体生产的效率，同时极大地改善电厌氧处理的污泥和废水的最终质量。在流2中定义的工作将集中在利用新型厌氧膜电生物反应器从废水中生产氢气-生物氢。该项目涉及对加拿大和世界都很重要的问题，即生产清洁能源和保护清洁水资源。许多城市和工业正在寻求以更低的成本和利用新的能源回收形式更可持续地处理其废水。预计已开发的系统还将服务于分散的处理系统、采矿和军事基地以及偏远的定居点，即使在北部地区也是如此。考虑了器件在低温下的验证问题。新技术将改善卫生和能源仍然不足的许多地区的生活质量。该项目的成功还取决于对在电场作用下厌氧消化器发生变化的微生物群落的深入研究--预计将对科学做出重大贡献。该项目将允许对至少15名HQP负责人进行废物深度处理和能源回收方面的培训。由于多学科的研究团队，HQP将接触到不同的科学领域，使他们变得更有知识，更有创造力和竞争力。
