MRI: Acquisition of a Dynamic Imaging Particle Analyzer for Characterization of Particulate Matters in Engineered and Natural Water Systems at Montclair State University

该奖项是为了购买一台动态成像颗粒分析仪(DIPA)，用于蒙特克莱尔州立大学(MSU)与水中颗粒相关的研究和培训。DIPA能够准确、快速地计数和表征水中的颗粒。它将作为密歇根州立大学现有两个研究领域的核心仪器：1)开发用于去除各种水污染物的创新水处理技术；2)鉴定和表征天然淡水中的藻类。此外，DIPA将被用于为密歇根州立大学开辟新的研究机会，包括测量与土壤侵蚀有关的暴雨径流颗粒，以及开发针对自然灾害的紧急水处理。DIPA将在密歇根州立大学不同系和项目的教职员工、研究人员和学生之间共享。该仪器还将用于教育和推广目的。颗粒物质(PM)，如粘土和藻类细胞，会显著降低工程和天然水系统的质量。有时，为了去除不受欢迎的水污染物(例如胶体)，故意生产PM(例如，添加混凝剂产生的絮状物)。对这些PM的准确和快速分析是密歇根州立大学水处理和淡水浮游植物核心研究领域成功的关键。建议的DIPA将提供一种实时和非侵入性的方式来对水中的PM进行成像、计数和表征。该仪器将为密歇根州立大学的多个项目提供新的研究机会，特别是环境工程、环境科学、生态学、生物学和化学。该工具还将用于帕塞伊克河研究所关于休闲用水安全的公共教育。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

This award is to purchase a Dynamic Imaging Particle Analyzer (DIPA) for research and training associated with particles in water at Montclair State University (MSU). The DIPA is capable of accurately and rapidly counting and characterizing particles in water. It will serve as a core instrument for two MSU's existing research areas: 1) the development of innovative water treatment technologies for the removal of various water pollutants and 2) the identification and characterization of algae in natural freshwater. Furthermore, the DIPA will be used to open new research opportunities for MSU, including the measurement of storm water runoff particulates related to soil erosion and the development of emergency water treatment for natural disasters. The DIPA will be shared among MSU faculty, research staff, and students across different departments and programs. The instrument will also be used for educational and outreach purposes.Particulate matters (PMs), such as clays and algal cells, can significantly degrade the quality of engineered and natural water systems. Occasionally, PMs (e.g. flocs from coagulant addition) are intentionally produced for removing undesirable water contaminants (e.g. colloids). Accurate and rapid analyses of these PMs are key to the success of MSU's core research areas in water treatment and freshwater phytoplankton. The proposed DIPA will provide a real-time and non-invasive way to image, count, and characterize PMs in water. This instrument will enable new research opportunities for multiple programs at MSU, particularly environmental engineering, environmental science, ecology, biology, and chemistry. The instrument will also be used for the Passaic River Institute's public education on recreational water safety.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
