Feasibility of combined upflow anaerobic sludge blanket-aerobic membrane bioreactor system in treating purified terephthalic acid wastewater and polyimide membrane for biogas purification

Improved anaerobic degradation of purified terephthalic acid wastewater by adding nanoparticles or co-substrates to facilitate the electron transfer process

“…using a two-stage up-flow anaerobic sludge blanket (UASB) reactor and a UASB reactor combined with an aerobic membrane bioreactor. [6][7][8] Considering that the anaerobic degradation of TA requires the mutual collaboration of TA/BA degrading microorganisms, fermentative bacteria that form acetate and H 2 nutrient methanogens, the electron transfer between the syntrophic bacteria and the methanogens may play a dominant role in improving the degradation efficiency of TA wastewater. 9 Potentially, the degradation efficiency of TA can be enhanced by amplifying the interspecific electron transfer processes.…”
