A comparative evaluation of reverse osmosis membrane performance when combined with anaerobic or aerobic membrane bioreactors for indirect potable reuse applications

Uv/Tio2 Photocatalysis as Post-Treatment for Anaerobic Membrane Bioreactor Effluent for Reuse

“…The systems were fed with settled municipal wastewater from the Cranfield University sewage works after settling in a primary settling tank. Details about the MBRs can be found in Huang et al (2022). Effluents used in adsorption and photocatalytic tests were sampled simultaneously from the AnMBR and AeMBR to minimize the effect on the effluent matrix caused by variation of influent wastewater.…”

“…Scan settings were 200-400 nm excitation and 280-500 nm emission wavelength, 1 nm entrance slit and an integration time of 0.1 s. The 1st and 2nd Rayleigh scatter was masked with 5 nm slit width by FluorEssence software (HORIBA, Japan). The fluorescence integrated composition analysis was extracted with as described in Huang et al (2022).…”

“…This can be explained by the fact that the high molecular weight (MW) carbon substances have a higher adsorption potential by TiO 2 (Benkoula et al, 2015;Thomas and Syres, 2012). Our previous work has suggested that the organic matter matrix is similar in the two effluents with a high content of humic acid-like substances (Huang et al, 2022), while the size distribution results displayed a negligeable difference in Dv50 (size point below which 50% of the material is contained) between all samples with the same TiO 2 doses (n = 10). Since the initial TC and IC concentrations in the AnMBR effluent were more than 4 times higher than for the AeMBR effluent, this suggests that the IC compounds in both effluents consist of high MW substances, while in contrast the other fraction of the TC has low MW.…”
