过滤器成熟期间出现的浊度峰值 不需要额外的设备或设备，就可以最小化 化学品，只需优化反洗步骤。然而 仍需实现废物过滤（FTW） 积极过滤出水浊度目标。 在中央湖县进行了一项研究 伊利诺伊州布拉夫湖联合行动水资源局，以最大限度地减少 耗水量和最大化过滤服务 生活过滤和用水优化使用 现有设备和一种称为扩展终端的方法 亚流态化清洗，证明 10年历史的生物活性颗粒活性炭 仍然可行。反冲洗后FTW峰值 从平均0.13减少到0.08 ntu。 此外，结果表明，FTW不是必需的 在96%的过滤器反洗中。因此，自动 应停止反冲洗后的FTW， 相反，FTW只能在需要时使用。包括54个参考文献、表格和图表。

The turbidity spike that occurs during filter ripening can be minimized without additional equipment or chemicals, simply by optimizing backwash steps. However, filter-to-waste (FTW) is still needed to achieve aggressive filter effluent turbidity targets. A study was undertaken at the Central Lake County Joint Action Water Agency in Lake Bluff, Illinois, to minimize water consumption and maximize filter service life. Filtration and water use were optimized using existing equipment and a method called extended terminal subfluidization wash, demonstrating that 10-year-old biologically active granular activated carbon is still viable. The FTW peak following backwash was reduced from an average of 0.13 to 0.08 ntu. In addition, results suggest that FTW is not required in 96% of filter backwashes. Therefore, automatic FTW following backwash should be discontinued and, instead, FTW should only be used as needed. Includes 54 references, tables, figures.
