The long term and general objective of the research program is to develop sustainable solutions for the treatment of Canadian industrial wastewaters, focusing especially on small systems that are not easily treatable and using technologies that not only treat the waste water, but consume less energy, are economically viable and in many cases will produce energy in the form of methane and/or waste heat. Many industrial waste streams contain high strength organic contamination or high concentrations of salts (brines). In addition to the contaminants in wastewaters, seasonality and variable or low volumetric flow rates are impediments to designing typical wastewater treatment plants for these industries. In many cases the wastewaters are not treated or are discharged to a local municipality for treatment. Municipalities struggle to treat these wastewaters because they use treatment processes designed for low strength municipal wastewater and not for high strength industrial wastewater. Typical aerobic treatment processes are inefficient for the treatment of high-strength wastewater. The short term objectives covered by this research proposal involve studies on the removal of perchlorate or nitrate from brines, the development of processes for the sustainable treatment of high strength winery waste and wastewater and the development of anaerobic processes to treat oil sands tailings water, converting the contaminants into energy. The research is unique in that the focus is on the treatment of small industrial wastewaters relevant to the Canadian economy and it will include the development of the basic science to support processes that are energy-efficient, suitable for small systems and may produce methane (biogas) as a renewable energy source. The methane can either be used by the producers to fuel their own generators for electricity, for heating, or be sold to fuel providers. Organisms degrading high strength wastes can also produce heat which can be recovered for other uses in the facility.

该研究计划的长期和总体目标是为加拿大工业废水的处理开发可持续的解决方案，特别关注不易处理的小型系统，并使用不仅处理废水，而且消耗更少能源的技术，经济上可行，在许多情况下将以甲烷和/或废热的形式产生能源。 许多工业废物流含有高浓度的有机污染物或高浓度的盐（盐水）。 除了废水中的污染物之外，季节性和可变或低体积流速也是为这些行业设计典型废水处理厂的障碍。 在许多情况下，废水未经处理或排放到当地市政当局进行处理。 城市努力处理这些废水，因为他们使用的处理工艺是为低浓度城市废水而不是高浓度工业废水设计的。 典型的好氧处理工艺对于高浓度废水的处理是低效的。 本研究提案涵盖的短期目标包括研究从盐水中去除高氯酸盐或硝酸盐，开发高强度酿酒厂废物和废水的可持续处理工艺，以及开发处理油砂尾矿水的厌氧工艺，将污染物转化为能源。 这项研究的独特之处在于，重点是处理与加拿大经济有关的小型工业废水，它将包括发展基础科学，以支持节能、适合小型系统并可产生甲烷（沼气）作为可再生能源的工艺。 甲烷可以被生产者用来为他们自己的发电机提供燃料，用于发电，供暖，或者出售给燃料供应商。 降解高强度废物的生物也可以产生热量，这些热量可以回收用于设施中的其他用途。
