本研究的目的是:使用工程陶瓷介质改善颗粒介质过滤； 评估操作稳健性和对化学混凝的依赖性； 建立一个基线，以便继续进行进一步的机理研究；和 评估微球作为隐孢子虫的替代物。概述了隐孢子虫和过滤的作用，以及性能演示实验装置、研究平台、中试工厂配置、合成水实验的实验条件、安大略湖水实验条件和机理实验。列出了初步结论和进一步测试。包括表格、数字。

The objectives of this study were to: improve granular media filtration using engineered ceramic media; evaluate operational robustness and dependency on chemical coagulation; establish a baseline from which to continue further mechanistic studies; and, evaluate microspheres as surrogates for Cryptosporidium. Cryptosporidium and the role of filtration is outlined, along with Performance Demonstration Experimental Set-Up, research platforms, pilot plant configuration, experimental conditions for synthetic water experiments, and Lake Ontario water experimental conditions and mechanistic experiments. Preliminary conclusions and further testing are listed. Includes tables, figures.
