A Zeta Potential Analyzer for the Understanding of Interfacial Phenomena and Particle Size Distribution for Environmental Engineering Applications

所有能源系统都必须解决与能源开发、管理和供应有关的环境问题。此外，需要解决目前许多补救和复垦标准缺乏科学依据的问题。此外，迫切需要制定土地和水的综合填海战略，以减少城市和工业发展对环境的影响。所要求的Zeta电位分析仪配备了颗粒测量，通过帮助评估环境工程领域中胶体物质的命运和运输，支持所有专注于土地和水的处理和开垦的研究项目。Zeta电位仪是估算纳米颗粒、无机胶体、蛋白质、病毒和细菌等各种胶体物质表面电荷的重要分析工具，而通过测定颗粒大小来估算固液分离效率则需要测定颗粒大小。对于我们的团队以及艾伯塔大学许多工程和科学学科的研究人员来说，该仪器将是一个极其有用的工具。目前需要使用分析仪的研究项目很少，包括：(1)开发用于土地和水围垦的新型吸附材料；(2)使用主动和工程改造的被动方法处理工艺水；(3)使用不同的混凝剂和助凝剂处理复合下水道溢流；以及(4)了解生物膜与水相成分的相互作用以及病原体在生物过滤系统上的附着。这些研究项目对加拿大具有战略重要性，因为它们提供了减少工业活动对环境的影响的处理和回收战略。此外，所要求的设备是一个重要的研究工具，将提供对分散机理的详细了解，并将有助于控制静电分散过程。通过在所描述的研究项目中使用配备颗粒测量的Zeta电势分析仪，最终将导致开发具有成本效益的处理和回收方法，并将有助于确保艾伯塔大学在环境工程和科学研究方面继续保持领先地位。

Environmental issues associated with energy development, management and supply must be addressed for all energy systems. Moreover, the lack of scientific basis for many current remediation and reclamation criteria needs to be addressed. In addition, there is an urgent need to develop integrated land and water reclamation strategies to reduce the impacts of urban and industrial development on the environment. The requested zeta potential analyzer equipped with particle sizing is indented to support all research projects focusing on the treatment and reclamation of land and water by helping evaluate the fate and transport of colloidal matters in the environmental engineering field. The zeta potential analyzer is an essential analytical tool used to estimate the electrical surface charge of various colloidal matters such as nanoparticles, inorganic colloids, proteins, virus, and bacteria, while the particle sizing is required to estimate the solid-liquid separation efficiency by determining the particle size distribution. The instrument will be an extremely useful tool for our groups as well as to researchers in many engineering and science disciplines at the University of Alberta. Few examples of current research projects that necessitate the requested analyzer include: (1) development of novel adsorption materials for land and water reclamation; (2) treatment of process water using active and engineered passive approaches; (3) treatment of combined sewer overflows using different coagulants and coagulant aids; and (4) understanding of the biofilm interactions with constituents in water phases and adhesion of pathogens on biofiltration systems. These research projects are of strategic importance to Canada because they provide treatment and reclamation strategies to reduce the impacts of industrial activities on the environment. Moreover, the requested equipment is an important research tool that will provide detailed insight into the dispersion mechanism and will help to control electrostatic dispersion processes. By using the zeta potential analyzer equipped with particle sizing in the described research projects will eventually lead to the development of cost-effective treatment and reclamation approaches, and will help ensure the continued leadership of the University of Alberta in environmental engineering and science research.
