污泥的流变特性代表了少数几个从根本上衍生的特性的例子之一，这些特性也已成功地用于改进实际的污泥处理过程。先前的研究建议使用某些污泥流变参数来优化聚合物剂量和絮凝体表征。本研究评估了流变特性在聚电解质污泥调节表征和控制中的应用。利用合成纤维素悬浮液和实际污泥，在实验室评估中将流变特性与脱水性进行比较。这些实验旨在确定可能用于评估和控制调节和脱水过程的基本流变参数。本文报告并分析了受控实验室实验的结果；对附近污泥处理设施过程控制的在线流变测量进行了评估……
Rheological characteristics of sludge represent one of the few examples of fundamentally derivable properties that have also been successfully used for the improvement of actual sludge treatment processes. Previous research has suggested the use of certain sludge rheological parameters for polymer dose optimization and floc characterization. This research evaluated the use of rheological properties for characterization and control of sludge conditioning with polyelectrolytes. Rheological characteristics were compared with dewaterability in laboratory evaluations, utilizing both synthetic cellulose suspension and actual sludge. These experiments were designed to identify fundamental rheological parameters that may have the potential to be used for assessment and control of conditioning and dewatering processes. This paper reports and analyzes results from controlled laboratory experiments; evaluations of on-line rheology measurements for process control in a nearby sludge handing facility have been present...
