大多数水回收法规，比如加利福尼亚州的第22条，主要是为了 保护公众健康。条例涵盖的主要水质参数包括: 浊度（或透明度）和消毒水平。然而，大多数工业用户使用的是回收的 水还涉及与结垢相关的水质参数， 腐蚀、生物污染、可达到的浓缩循环次数以及 空气中颗粒物排放的可能性。本文讨论了附加的 与使用循环水进行工业冷却有关的水质问题。例子 重点介绍了现有的工业循环水用户。包括2个参考文献、表格和图表。

Most water recycling regulations, such as Title 22 in California, are primarily intended to protect public health. The main water quality parameters covered by the regulations are turbidity (or clarity) and level of disinfection. However, most industrial users of recycled water are also concerned with water quality parameters that are related to scaling, corrosion, biofouling, the number of cycles of concentration that can be achieved and the potential for emissions of airborne particulate matter. This paper discusses the additional water quality issues related to use of recycled water for industrial cooling. Examples of existing industrial recycled water users are highlighted. Includes 2 references, tables, figure.
