Using MIEX® Resin and Membrane Filtration to Treat a Challenging Source Water in a Fort McMurray, Alberta, Canada Work Camp 使用MIEX®;在加拿大阿尔伯塔省麦克默里堡的一个工作营地 树脂和膜过滤处理具有挑战性的水源水
发布日期: 2009-11-01
森科尔航行者(SV)水处理厂(WTP)位于麦克默里堡, 加拿大阿尔伯塔省。0.5 MGD发电厂的原水来自阿萨巴斯卡河和 将为大约3500人的工作营地提供饮用水。一些 与工艺设计相关的挑战是非常高的日耗水量 峰值、设施间歇运行和广泛的水源水质。在项目的初始阶段,对许多处理方案进行了评估, 包括MIEX®预处理和压载絮凝,然后是微滤膜。 其目的是实现一种在宽温度下运行良好的工艺 范围内,提供足够的DBP前体去除,并可经历尽可能多的启动/停止 在不影响性能的情况下,根据需要进行循环。除铁也是目标。 作为该项目的一部分,使用压载絮凝法进行了大量台架试验 在各种条件下,包括环境温度和低温下。这些结果 与科罗拉多州大麋鹿草地水处理厂(WTP)的运行数据进行了比较,该处理厂采用50 gpm MIEX/膜 过滤水处理厂。该电厂面临着与SVWTP类似的挑战,例如32ºF 温度和总有机碳(TOC)高达16 mg/L。包括2个参考文献、表格和图表。
The Suncor Voyageur (SV) Water Treatment Plant (WTP) is located in Fort McMurray, Alberta, Canada. The raw source water for the 0.5 MGD plant is obtained from the Athabasca River and will provide potable water for a work camp of approximately 3,500 people. Some of the challenges associated with the process design were the very high daily water consumption peaks, intermittent operation of the facility, and a wide range of source water quality. During the initial phase of the project a number of treatment alternatives were evaluated, including MIEX® pretreatment and ballasted flocculation, followed by microfiltration membranes. The objective was to implement a process that could operate well under a wide temperature range, provide for adequate DBP precursors removal and could undergo as many start/stop cycles as necessary, without compromising performance. Iron removal was also targeted. As part of this project a number of bench-scale tests were performed using ballasted flocculation and MIEX under a variety of conditions, including ambient and cold temperatures. These results were compared to operational data of Big Elk Meadows Water Treatment Plant (WTP), Colorado, a 50 gpm MIEX/membrane filtration WTP. This plant deals with similar challenges as the SVWTP, such as 32ºF temperatures and total organic carbon (TOC) up to 16 mg/L. Includes 2 references, tables, figures.
