该项目的目标是描述康涅狄格州六家BHC公司地表水处理厂的回收实践，并研究水质影响。该项目的范围包括检查现有的循环水水质数据，了解现场具体的反洗和循环实践，并进行现场取样和分析，以检查水质影响。水质评估包括描述循环水、原水、混合工厂进水和下游工艺水（即澄清和过滤水）的特征。水质参数包括pH值、温度、总悬浮固体、浊度、颗粒数、有机碳、铝和锰的总含量和溶解分数。包括10个参考文献、图表。

The objectives of this project were to characterize recycle practices at six BHC Company surface water treatment plants in Connecticut and to study water quality impacts. The scope of the project entailed examining existing recycle water quality data, understanding site specific backwash and recycle practices, and conducting on-site sampling and analysis to examine water quality impacts. Water quality assessment involved characterizing recycle water, raw water, mixed plant influent and downstream process waters (i.e., clarified and filtered waters). Water quality parameters included pH, temperature, total suspended solids, turbidity, particle counts, and total and dissolved fractions of organic carbon, aluminum and manganese. Includes 10 references, figures.
