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.
