Fundamental Studies and Chemical and Engineering Innovationsin Flocculative Water Cleaning

9520573 MAGEE这个奖项是一个为期三年的合作项目，将在新泽西理工学院的危险废物管理行业/大学合作研究中心和位于英国北爱尔兰贝尔法斯特的女王大学环境科学和技术中心(Questor)共同研究。这项研究旨在提高使用絮凝进行净化的水处理设施的效果和效率。Questor的研究人员得到了当地工业财团的资助，以设计、建造和运营一个试点水处理厂，以设计使用絮凝添加剂的新方法，以扩大絮凝清洗的范围和效率。I/UCRC的研究将集中在絮凝剂流体动力学的一些基本方面。通过确定几种絮凝室构型中的局部速度梯度的空间分布，可以确定在絮凝器中运动的普通絮体颗粒的速度梯度时间积分。这可以用来准确地量化许多絮凝配置的这一关键参数的值，以确定絮体的聚集和破坏。这项研究应该阐明絮凝的基本流体动力学方面的问题，以改进净水工艺。

9520573 Magee This award is a collaborative three-year project to be studied jointly at both the New Jersey Institute of Technology's Industry/University Cooperative Research Center for Hazardous Waste Management and the Queen's University Environmental Science and Technology Center (QUESTOR) at Belfast, Northern Ireland, UK. The study is designed to improve the effectiveness and efficiency of water processing facilities that use flocculation for purification. The QUESTOR researchers have been funded by a consortium of local industries to design, build and operate a pilot water treatment plant to devise new approaches to the use of flocculation additives to extend the range and efficiency of flocculative cleaning. The I/UCRC studies will focus on some fundamental aspects of the fluid dynamics of flocculators. By determining the spacial distribution of local velocity gradients in a number of flocculation vessal configurations, the velocity gradient time integral for a generic floc particle moving in the flocculator can be determined. This can be used to accurately quantify the value of this key parameter for a number of flocculation configurations to determine floc aggregation and breakage. The study should elucidate the fundamental fluid dynamic aspects of flocculation for process improvement in water purification.
