摘要

Backwash water chemistry can have significant detrimentaleffects on filtered water quality under some circumstances.Water utilities experiencing adverse backwash waterchemistry can significantly improve water quality, protect publichealth, and help ensure regulatory compliance by applying theinformation set forth in this article.Delayed start and backwash water chemistry can range fromplaying a large role to having no effect on filtered water quality,depending on treatment conditions. Indeed, delayed start hasbeen known to work well at some locations and not at others. Inthis article, the authors explain the details of why this techniquemay or may not be effective and how to evaluate what methodsare most effective at a particular facility. With the insights in thisarticle, some water suppliers will be able to make minor operationalchanges that will significantly improve filtered water qualityfrom their facility. Includes 24 references, tables, figures. 反冲洗水化学可能会产生重大不利影响在某些情况下对过滤水质量的影响。遭遇不利反冲洗水的供水设施化学可以显著改善水质，保护公众健康并通过应用本条所述信息。延迟启动和反洗水化学成分的范围为对过滤后的水质没有影响起到很大作用，取决于治疗条件。事实上，推迟启动已经开始在某些地方工作良好，而在其他地方则不然。在里面在本文中，作者详细解释了为什么使用这种技术可能有效，也可能无效，如何评估哪些方法在特定设施中最有效。有了这些见解第二条，一些供水商将能够进行小型运营将显著改善过滤水质量的变化从他们的设施。包括24个参考文献、表格和图表。展开▼
