本powerpoint演示文稿首先提供了管道内部缩放层的背景信息，其中包含 腐蚀副产物。介绍了德克萨斯州的一个案例，以及自来水质量和管道水的相互作用。主要观察结果包括: 配电系统是复杂而动态的 （腐蚀、硝化、生物再生长）； 化学和生物稳定的水将 减少管道材料对水的影响 质量和 选择合适的管道材料或内衬管道 新管道或更换管道。 包括数字。

This powerpoint presentation begins by providing background information on the internal layers of scale inside pipes that contain corrosion byproducts. An example of a case in Texas is presented, along with tap water quality and pipe water interactions. Key observations include: distribution systems are complex and dynamic (corrosion, nitrification, biological re-growth); chemically and biologically stable water will reduce the influence of pipe materials on water quality; and, select benign pipe materials or lined pipes for new or replacement pipes. Includes figures.
