Brentwood’s engineering team is happy to announce that Dr. Shanshan Jin, Senior Process Engineer, will be presenting at the Dallas Convention Center during AWWA ACE ‘12 on June 12, 2012. 她的#TUE25会议将于下午2点开始，她的演讲将于下午3:30开始。

本文将讨论污泥疏浚（SD）型污泥收集系统的一系列性能评估测试和随后的设计改进。 The SD system consists of a wing design that removes settled solids from the bottom of the clarifier tanks.  Design configurations employing submersible pumps versus vacuum,  integral motor drive (self-driven) versus cable drive (cable-driven) were tested in a rectangular clarifier in a 3.4 MGD water treatment plant over 16 months period. The sludge discharge rate, solids concentration and TSS for each configuration at various influent conditions were monitored.  对每种配置进行统计分析。  并对其除砂效果和固体增稠效果进行了评价。  The performance data were then combined with the clarifier influent/effluent conditions and the site specific conditions to determine the design recommendations for every one of the four configurations.  成本分析和功率优化是基于这些建议生成的。  机翼设计进一步与另一种流行的收集器形状-管道设计进行了比较。 本研究为SD型污泥收集系统的设计考虑提供了见解。  该研究还提出了适合各种工厂条件的优选系统设计，这可能会降低污泥去除过程和污泥处置过程的成本。 我们很荣幸能代表布伦特伍德工业公司参加这次会议。

AWWA ACE ' 12将于2012年6月5日至8日在美国德克萨斯州达拉斯市的达拉斯会议中心举行。
