CBET- 0747602KupferleThe central vision for this CAREER award is that sustainable waste treatment technology must be designed and operated in a way that returns the elements in a waste to environmentally-friendly forms using renewable energy to drive the process. The objective of the research aspect of this project is to test the hypothesis that the amount and species of undesirable chlorinated byproducts produced in electrochemical treatment of chloride-bearing waste depend on reactor configuration, anode material, anode potential, applied current and chlorine-to-contaminant ratio in the waste. Phenol will be used as a model compound, and energy input and changes in phenol, carbon species, oxygen demand, and chlorine species will be measured as treatment proceeds under different reaction conditions in a full factorial design. Exploratory data analysis and analysis of variance techniques will be applied to the data to identify which parameters, individually and interactively, have the most impact on power consumption and production of undesirable chlorinated byproducts.The education objective of this project is to use the knowledge gained to increase public and professional understanding of1) sustainable engineering solutions based on an elemental cycle approach,2) chlorine chemistry in a broader context than typically explored in environmental curricula, and3) appropriate use of electrochemical treatment systems.

CBET- 0747602Kupferle 该职业奖的中心愿景是，可持续废物处理技术的设计和运行方式必须使用可再生能源驱动该过程，将废物中的元素返回到环境友好的形式。该项目研究的目的是检验以下假设：含氯废物电化学处理中产生的不良氯化副产物的数量和种类取决于反应器配置、阳极材料、阳极电位、施加电流和废物中的氯与污染物的比率。苯酚将用作模型化合物，在全析因设计中，随着处理在不同反应条件下进行，将测量能量输入以及苯酚、碳物种、需氧量和氯物种的变化。探索性数据分析和方差分析技术将应用于数据，以确定哪些参数（单独和交互）对电力消耗和不良氯化副产品的生产影响最大。该项目的教育目标是利用所获得的知识来提高公众和专业人士对1）基于元素循环方法的可持续工程解决方案的理解，2）比环境课程中通常探讨的更广泛背景下的氯化学， 3) 适当使用电化学处理系统。
