Today's search for new resources advances exploration in remote cold regions and arid zones. In Canada, the province of Quebec has recently announced Le plan nord. Moreover, the Middle East and African countries have invested aggressively in the development of their arid areas. Such rapid developments in remote cold regions and arid zones might have important negative consequences including the generation of waste and the production of emissions, which very likely to create irreversible negative impacts on the environment if they are not restrained by the application of adequate technologies. Unfortunately, the reality is that today's commonly used technologies are not efficient in extreme climate conditions. The main objective of this five-year project is the development of new technologies, efficiently operating in extreme weather conditions, that will treat residential and industrial slurries as well as liquid and solid waste. A series of sub-projects will address particular issues associated with wastewater and sludge treatment and the energy recovery from waste and gas emissions. Previous work proved that the electrokinetic phenomena and certain electrochemical methods combined with other processes permitted to significantly enhance the treatment efficiency and that independently of temperature. The project will address the development of new treatment facilities that will be flexible to dramatic flow rate change and that will permit complete nutrient, carbon, metal, and endocrine disruptor removal. Extended investigations of mix microbial consortium and membrane filtration processes will be investigated for modular and for mobile systems adapted to remote locations. New technologies will eliminate large ponds and decrease devastating impacts on permafrost and air quality. Investigation of sequestration of CO2 will be also carried out. Besides bringing a valuable contribution to knowledge, the outcomes from this research will be immediately applicable to the industry, compounds and aboriginal villages in the Canadian northern territories and in other northern. The research's outcomes in regards to elevated temperature conditions can be applied by Canadian companies in the Gulf region and in African countries.

今天对新资源的寻找推动了对偏远寒冷地区和干旱地区的勘探。在加拿大，魁北克省最近宣布了LeNord计划。此外，中东和非洲国家积极投资于干旱地区的发展。偏远寒冷地区和干旱地区的这种快速发展可能会产生重要的负面后果，包括产生废物和排放，如果不应用适当的技术加以限制，很可能对环境造成不可逆转的负面影响。不幸的是，现实情况是，今天常用的技术在极端气候条件下并不有效。这项为期五年的项目的主要目标是开发在极端天气条件下高效运行的新技术，这些技术将处理住宅和工业泥浆以及液体和固体废物。一系列次级项目将处理与废水和污泥处理以及从废物和气体排放中回收能源有关的特殊问题。以前的工作证明，电动现象和某些电化学方法与其他工艺相结合，可以显著提高处理效率，而且不受温度的影响。该项目将致力于开发新的处理设施，这些设施将灵活地应对巨大的流速变化，并允许完全去除营养、碳、金属和内分泌干扰物。将对适用于偏远地区的模块化和移动式系统的混合微生物联合体和膜过滤过程进行深入调查。新技术将消除大池塘，减少对永久冻土和空气质量的破坏性影响。还将对二氧化碳的封存进行调查。除了为知识带来有价值的贡献外，这项研究的结果将立即适用于加拿大北部地区和其他北部地区的行业、院落和土著村庄。加拿大公司可以在海湾地区和非洲国家应用这项关于高温条件的研究成果。
