“…The results show that the UASB process can anaerobically treat a wide selection of different types of matrices with different HRTs depending on the type of matrices and the reactor operating temperature. Generally, industrial matrices required a higher HRT (and lower OLR) than urban wastewater due to the greater recalcitrance of the organic substance [ 32 , 39 , 41 ]. Furthermore, thermophilic reactors have generally allowed researchers to operate in lower HRT conditions thanks to the faster reaction kinetics that permit to fed higher OLR, as has already been confirmed by the previous literature [ 112 ].…”

“…To degrade organic substances and produce methane, the UASB process was tested on synthetic matrices [24][25][26][27][28][29] and real feed, mainly toilet wastewater [30,31], urban wastewater [32], distillery wastewater [33], mining wastewater [34,35], leachate [35,36], brewery wastewater [37], food waste [38], soybean molasses [39], pharmaceutical wastewater [40], and pulp mill wastewater [41].…”

The interest in research on up-flow anaerobic sludge blanket (UASB) reactors is growing. The meta-analysis of bibliometric data highlighted the growing interest in four diverse topics: (i) energy recovery production; (ii) combination with other treatments; (iii) the study of processes for the removal of specific pollutants and, (iv) characterization of microbial community and granular sludge composition. In particular, the papers published in the first 6 months of 2021 on this process were selected and critically reviewed to highlight and discuss the results, the gaps in the literature and possible ideas for future research. Although the state of research on UASB is to be considered advanced, there are still several points that will be developed in future research such as the consolidation of the results obtained on a semi-industrial or real scale, the use of real matrices instead of synthetic ones and a more in-depth study of the effect of substances such as antibiotics on the microbiota and microbiome of UASB granular biomass. To date, few and conflicting data about the environmental footprint of UASB are available and therefore other studies on this topic are strongly suggested.

“…Meanwhile, due to anaerobiosis, the level of color in the outlet of the UASB increases since anaerobic bacteria are not capable of degrading lignin chromophoric structures. But using the NF after the anaerobic and aerobic stages decreased the level of color . Moreover, ozonation can be used to treat the NF permeate (Figure ).…”

The pulp and paper industry generates vast amounts of wastewater, and its character heavily depends on various factors (raw material, the undertaken process, the final product, etc.). The wastewater from this sector, which originates from several sources in each mill and are mostly combined, is polluting and hazardous. This paper presents a state-of-the-art review of the physical, chemical, biological, and advanced hybrid treatment techniques, concerning their effectiveness in removing specific pollutants, namely, chemical oxygen demand, lignin, color, and adsorbable organo-halogens. Throughout the manuscript, at the end of each section, a conclusive comparison has been presented and the proper method is introduced. Furthermore, numeric data regarding the effectiveness of each technique toward each pollutant are gathered from the literature and are available in the Supporting Information of the paper. Biological treatment processes using anaerobic–aerobic treatment mostly cure organic biodegradable contaminants (75–90% COD removal). Moreover, biological treatment using a consortium of microorganisms can potentially increase color removal efficiency (from 65 to 97%). Hybrid treatment is also among the candidates for color removal. To treat complex matters (lignin and AOX), physical and chemical treatments have shown promising performance, but they are generally expensive and impractical to treat huge amounts of wastewater. For the treatment of high molecular weight contaminants (lignin) advanced oxidation processes (AOPs), including ozonation and Fenton-based treatment, have shown great performance (90–99%); however, they are limited due to their maintenance and operation costs. To overcome these challenges, source separation of the wastewater streams in the pulp and paper industry is recommended. AOPs or membrane technologies or hybrid processes are suggested for the bleaching effluent (80% AOX removal), which is relatively low in amount, and a combination of conventional treatment processes would be preferred to treat wastewater streams that are more biodegradable. The biological performance can also be enhanced using granular activated carbon on the sequence. Finally, for treating black liquor, adsorption processes have proven to be the prime candidate.
