本文旨在为那些评估水处理厂的人员提供指导，以降低过滤厂生产的成品水的浊度，其中化学混凝是处理过程的一部分。浊度去除效果不佳可能与多个因素有关，包括设施的物理条件、处理过程的水力、水质和操作人员的能力。通过预先规划，可以以逻辑方式进行评估，从而考虑电厂及其运行的所有必要和重要方面。描述了工艺序列中每个组件的正确操作，以及提高性能的实用补救措施。包括48个参考文献、图表。

This article is intended to serve as a guide for those who evaluate water treatment plants with the objective of lowering the turbidity of finished water produced from filtration plants in which chemical coagulation is part of the treatment process. Ineffective removal of turbidity may be related to several factors, including the physical condition of the facilities, the hydraulics of treatment processes, the quality of water, and the competence of the operating staff. By preplanning, the evaluation can be conducted in a logical fashion that results in consideration of all necessary and important aspects of the plant and its operation. Descriptions of the proper operation of each component in the process train and pragmatic remedies to improve performance are given. Includes 48 references, figures.
