Dynamic time sweep measurement of sludge for four different concentrations (3%, 4%, 5% & 5.5%) at four different gas flow rates (1 Lpm to 7 LPM).

This submission contains the raw rheometer files from time sweep measurements of waste activated sludge (total solids content = 3%, 4%, 5% &amp; 5.5% ). The sludge samples were measured at various gas flow rates (1 LPM to 7 LPM). The dynamic time sweep measurements were generated from the sludge sample first without gas at 0.09% strain across 25 minutes. Then the sample was conditioned and the gas was injected for 20 minutes before the measurement at similar conditions. Similar procedure was repeated for different concentrations <br> The measurements were carried out on a DHR-3 rheometer (TA-Instruments), equipped custom made cup. For detail procedure refer: Bobade, V, et al. 2017, 'Impact of gas injection on the apparent viscosity and viscoelastic property of waste activated sewage sludge', <i>Water Research</i>, vol. 114, pp. 296-307. Detailed experimental protocol is recorded in the .tri (TRIOS) file attached with each data set. This file can be read using the TRIOS software made available on TA-Instruments website (http://www.tainstruments.com/support/software-downloads-support/downloads/). Rheometer geometry dimensions and other details are also obtainable from these files. Please contact authors for access to files.

本提交数据集包含剩余活性污泥（waste activated sludge）时间扫描测试的原始流变仪文件，该类污泥的总固体含量分别为3%、4%、5%及5.5%。
所有污泥样品均在1 LPM至7 LPM的多种气体流速条件下完成测试。
首先，对污泥样品在无气体通入、应变为0.09%的条件下，开展了时长25分钟的动态时间扫描测试。随后对该样品进行预处理，并通入气体预处理20分钟，再在相同实验条件下重复测试流程。针对不同总固体含量的污泥样品，上述实验步骤均被重复执行。

本次测试均在配备定制样品杯的DHR-3型流变仪（TA-Instruments）上完成。详细实验步骤可参考如下文献：Bobade V 等. 注入气体对剩余活性污泥表观黏度及黏弹性的影响[J]. 水研究, 2017, 114: 296-307.
