必须针对所有能源系统处理与能源开发、管理和供应有关的环境问题。此外，许多现行的修复和填海标准缺乏科学依据，需要加以解决。此外，迫切需要制订综合的土地和水复垦战略，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尺寸，通过帮助评估环境工程领域胶体物质的命运和运输，以支持所有关注土地和水的处理和回收的研究项目。zeta电位分析仪是估计各种胶体物质（如纳米颗粒、无机胶体、蛋白质、病毒、细菌）表面电荷的必要分析工具，而粒度则需要通过确定粒度分布来估计固液分离效率。该仪器将是我们的小组以及阿尔伯塔大学许多工程和科学学科的研究人员非常有用的工具。目前需要所需分析仪的研究项目的几个例子包括：(1)开发用于土地和水复垦的新型吸附材料；(2)采用主动和工程被动方法处理工艺水；(3)采用不同混凝剂和助凝剂处理合流污水溢流；(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，将提供详细的了解扩散机制，并将有助于控制静电扩散过程。通过在上述研究项目中使用配备粒度的zeta电位分析仪，最终将导致经济有效的处理和回收方法的发展，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。

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.
