Advanced Technologies for Water and Wastewater Treatment

由于人口增长、快速城市化和工业化、与水有关的灾害、气候变化和缺乏治理，全球水资源面临巨大压力。节约用水、保护水源、再生、回收和再利用被确定为解决全球淡水危机的最有效的水管理方法。 在这些主题下，根据申请者关于可持续水和废水技术的既定和正在进行的研究计划，拟议的研究将处理重要的水问题，即饮用水安全、工业废水回收和资源回收。未来五年拟议研究的短期目标旨在开发和优化以下技术：(A)减少饮用水中产生的消毒副产品(DBP)中的藻类物质；(B)处理和回收含有复杂油类、溶解有机物和重金属的含油废水；以及(C)从工业废水中去除微量污染物以供循环使用的三级处理。 该计划涉及的技术基于物理化学原理的新发展，即混凝、吸附、膜分离和具有过程强化的高级氧化过程、过程模型的开发和成本分析。具体地说，在未来五年，拟议的研究将涉及(I)难以去除细胞内的亲水性藻类物质，确定最佳的预处理和混凝条件，(Ii)回收由混凝剂金属和藻类物质形成的生物絮凝剂，(Iii)减轻藻类物质与天然有机物相互作用造成的膜污染，(Iv)确定减少藻类相关消毒副产物的最佳处理条件，(V)表征同时去除有毒金属和有机物的新型吸附剂组合，以及(Vi)用于处理微量有机物的集成新型振荡膜分离器和光催化反应器。 DG提案的长期研究目标是促进基础环境科学知识，开发具有成本效益的创新技术，以实现有效的水管理和水源保护。到2020年，全球水市场的规模可能达到1万亿美元，许多世界领先的水务公司都设在加拿大。在该计划中培训的HQP将为人才库做出贡献，以保持加拿大在这一重要工业部门的领先地位。

Global water resources are under tremendous strain due to population growth, rapid urbanization and industrialization, water-related disasters, climate change and lack of governance. Water conservation, source water protection, reclamation, recycling and reuse are identified as the most effective water management approaches to solve the global freshwater crisis. Under these themes, and in accordance with the established and on-going research program of the applicant on sustainable water and wastewater technologies, the proposed research will deal with important water issues namely drinking water safety, industrial wastewater recycling, and resource recovery. The short-term objectives of proposed research for the next five years are aimed at developing and optimizing technologies for: (A) reduction of algal matter produced disinfection by-products (DBP) in drinking water; (B) treatment and recycling of oily wastewater with complex composition of oil, dissolved organics, and heavy metals; and (C) tertiary treatment for removal of trace contaminants from industrial effluents for recycling. The technologies involved in the program are based on new developments of physico-chemical principles namely coagulation, adsorption, membrane separation and advanced oxidation processes with process intensification, development of process models and cost analysis. Specifically, over the next five years, the proposed research will address (i) difficult removal of hydrophilic intracellular algal matter determining optimum pretreatment and coagulation conditions, (ii) recovery of bio-flocculants formed by coagulant metal and algal matter, (iii) alleviation of membrane-fouling due to interactions of algal matter with natural organic matter, (iv) determine optimum treatment conditions for the reduction of algae related disinfection by-products, (v) characterization of novel combination of adsorbents for simultaneous removal of toxic metal and organics, and (vi) integrated novel oscillatory membrane separator and photocatalytic reactor for the treatment of trace concentration of organics. The long-term research objectives of the DG proposal are to contribute to the knowledge on basic environmental sciences and develop innovative and cost-effective technologies for efficient water management and source water protection. Global water market will be potentially $1 trillion by 2020, and many of the world's leading water companies are located in Canada. The HQPs trained in the program will contribute to the talent pool to maintain the leading role of Canada in this vital industrial sector.
