艾伯塔省环境局为该地区的颗粒物控制制定了新的绩效标准 饮用水，这给埃德蒙顿的水处理厂带来了新的挑战。基于 颗粒计数技术作为饮用水检测新工具的研究 在工业界，为了兼容，需要从新的角度来设计过滤介质 使用新技术。本文总结了过滤介质研究的结果 包括一个试点阶段1和一个全面阶段2。这项研究是在英国进行的 2001年至2002年，检查不同过滤介质设计在不同条件下的性能 严格的颗粒计数标准。本研究的目的是寻找一种过滤系统 这可以使成品水中的颗粒计数水平远低于新标准。 这个 本研究的最后一个建议是使用双介质过滤器。该过滤器由一个550毫米的过滤器组成 有效尺寸为0.35 mm的沙子深度和200 mm深度的无烟煤深度 有效尺寸为0.9毫米的沙子。E.L.史密斯水处理厂 在EPCOR中，通过使用这种新的过滤介质设计来更换其过滤介质 旧的过滤介质设计于2003年。包括2个参考文献、表格和图表。

Alberta Environment has set a new performance standard for particulate control in drinking water, which sets a new challenge for Edmonton's water treatment plants. Based on using particle-counting technology as a new measurement tool for the drinking water industry, a new perspective for filter media design is required in order to be compatible with the new technology. This paper summarizes the results from a filter media study that included a pilot-scale phase 1 and a full-scale phase 2. This study was conducted from 2001 to 2002 to examine the performance of different filter media designs under a stringent particle count standard. The purpose of this study was to find a filtration system that can keep particle count levels in finished water well below the new standard. The final suggestion of this study is a dual-media filter. This filter consists of a 550 mm depth of sand with an effective size of 0.35 mm and a 200 mm depth of anthracite with an effective size of 0.9 mm on the top of the sand. The E. L. Smith Water Treatment Plant in EPCOR is upgrading its filter media by using this new filter media design to replace the old filter media design in 2003. Includes 2 references, table, figures.
