Journal ArticleDOI
TL;DR: This study compares the performance and the treatment capability of an anaerobic baffled reactor (ABR), an aerated completely mixed activated sludge reactor (AS), and a UV/H2O2 process, as well as their combination for the removal of the total organic carbon (TOC).

TL;DR: The optimal HRT was 12h for thermal hydrolysis liquid and 8h for acidogenic liquid, with NO3--N removal efficiency of 91.0% and 97.6%, respectively, while the optimal denitrification rate (VDN) was 8h.

TL;DR: The results of denaturing gel gradient electrophoresis (DGGE), 16S rDNA gene sequence analysis, and hierarchical cluster analysis showed that the microbial community structures in MBfR were of low diversity, simple and stable at mature stages; and the beta-Proteobacteria probably play an important role in autohydrogenotrophic denitrification.

Journal ArticleDOI
TL;DR: In this paper, the treatment of wastewater generated from fruit juice industry (24-30 m3/batch) was investigated, and three treatment schemes have been investigated: batch activated sludge (AS) system, two-stage up-flow anaerobic sponge reactors (UASRs), and two-staged UASRs were operated at a total hydraulic retention time (HRT) of 13-h corresponding to an organic loading rate (OLR) of 8.7-kg COD/m3
