已经开发了两种新的浊度计，以帮助优化水处理厂的过滤器性能。一个浊度计的设计目的是对反洗循环中的浊度变化做出简单、准确和快速的响应。另一个专门设计用于监测过滤废水。在这项研究中，仪器用于监测过滤前检测到的过滤废水事件。最终目标是通过识别和随后减少过滤前或反洗循环期间发生的颗粒事件来优化电厂性能。还讨论了使用这些技术的成本和收益。包括表格、数字。

Two new nephelometers have been developed to help optimize filterperformance at water treatment plants. One nephelometer was designed to give simple, accurate, and rapid response to turbidity changes during a backwash cycle. The other was designed specifically to monitor filter effluent. During this study, the instrumentation was used to monitor the filter effluent for events detected before filtration. The ultimate goal will be to optimize plant performance through identification and subsequent reduction of particle events that occur prior to filtration or during the backwash cycle. The costs and benefits of using these technologies are also addressed. Includes tables, figures.
