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.

所有能源系统都必须处理与能源开发、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综合回收战略，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功能，旨在通过帮助评估环境工程领域中胶体物质的归宿和运输，支持所有以土地和水的处理和回收为重点的研究项目。Zeta电位分析仪是用于估计各种胶体物质（如纳米颗粒、无机胶体、蛋白质、病毒和细菌）的表面电荷的基本分析工具，而粒度测量需要通过确定粒度分布来估计固液分离效率。该仪器将是一个非常有用的工具，为我们的团体，以及在许多工程和科学学科的研究人员在阿尔伯塔大学。目前的一些研究项目需要所要求的分析仪的例子包括：（1）开发新的吸附材料的土地和水回收;（2）处理工艺用水使用主动和被动的方法;（3）处理合并污水溢流使用不同的混凝剂和助凝剂;（4）了解生物膜与水相组分的相互作用以及病原体在生物过滤系统上的粘附。这些研究项目对加拿大具有战略重要性，因为它们提供了处理和回收战略，以减少工业活动对环境的影响。此外，所要求的设备是一个重要的研究工具，将提供对分散机制的详细了解，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尺寸的zeta电位分析仪，最终将导致开发具有成本效益的处理和回收方法，并将有助于确保阿尔伯塔大学在环境工程和科学研究方面的持续领导地位。
