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% & 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 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', Water Research, 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.
