Fundamental Studies and Chemical and Engineering Innovationsin Flocculative Water Cleaning

该奖项是一个为期三年的合作项目，将由新泽西理工学院的工业/大学危险废物管理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与技术中心（QUESTOR）共同研究。本研究旨在提高絮凝净化水处理设施的效能和效率。QUESTOR的研究人员得到了当地工业财团的资助，设计、建造和运营一个试验性水处理厂，设计使用絮凝添加剂的新方法，以扩大絮凝清洁的范围和效率。I/UCRC的研究将集中在絮凝器流体动力学的一些基本方面。通过确定若干絮凝血管构型中局部速度梯度的空间分布，可以确定一般絮凝颗粒在絮凝器中运动的速度梯度时间积分。这可以用来准确地量化这一关键参数的值，以确定絮凝体的聚集和破坏。该研究应阐明絮凝的基本流体动力学方面，以改进水净化工艺。

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.
