“…The necessity of post-treatment UASB effluents has been pointed out by several authors [ 19 , 78 ]. One of the main reasons is the residual presence of microorganisms and chemical pollutants that could be a potential threat to human and wildlife health.…”

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.

“…Many studies evaluated the efficiency of diverse post-treatment in order to increase the effluent quality. For instance, de Oliveira and Daniel [ 19 ] found 28–33 oocysts L −1 of Cryptosporidium spp. and 3177–4267 cysts L −1 of Giardia spp.…”

“…On the other hand, the UASB technology has some disadvantages that need to be addressed, such as slow start-ups (mitigated by inoculation with granular biomass) and the required treatment of effluent for the removal of nutrients and pathogens [ 83 ]. Indeed, substantial quantities of pathogenic organisms such as Cryptosporidium and Giardia have been identified in UASB effluents [ 84 ], which could lead to human and environmental health concerns.…”

“…There are limited studies of non-archaeal, non-bacterial microorganisms (for example, Eukarya) in UASB systems, given that they do not play a major role in the functioning of the technology; however, it has been found that several genera are usually present, such as Epistylis , Telotrochidium , Tetrahymena and Vorticella (phylum Ciliophora ), Phalansterium and Saccamoeba (phylum Amoebozoa ), Cercomonas , Heteromita , and Rhogostoma (phylum Cercozoa ), and Protoperidinium (phylum Dinoflagellata ) [ 85 ]. Moreover, parasitic Cryptosporidium (phylum Apicomplexa ) has been detected in UASB effluents [ 84 ], which raises concerns about the safe handling of UASB-treated water streams.…”

Nowadays, the discharge of wastewater is a global concern due to the damage caused to human and environmental health. Wastewater treatment has progressed to provide environmentally and economically sustainable technologies. The biological treatment of wastewater is one of the fundamental bases of this field, and the employment of new technologies based on granular biofilm systems is demonstrating success in tackling the environmental issues derived from the discharge of wastewater. The granular-conforming microorganisms must be evaluated as functional entities because their activities and functions for removing pollutants are interconnected with the surrounding microbiota. The deep knowledge of microbial communities allows for the improvement in system operation, as the proliferation of microorganisms in charge of metabolic roles could be modified by adjustments to operational conditions. This is why engineering must consider the intrinsic microbiological aspects of biological wastewater treatment systems to obtain the most effective performance. This review provides an extensive view of the microbial ecology of biological wastewater treatment technologies based on granular biofilms for mitigating water pollution.

By summarizing 187 relevant research articles published in 2019, the review is focused on the research progress of physicochemical processes for wastewater treatment. This review divides into two sections, physical processes and chemical processes. The physical processes section includes three subsections , that is, adsorption, granular filtration, and dissolved air flotation, whereas the chemical processes section has five subsections , that is, coagulation/flocculation, advanced oxidation processes, electrochemical, capacitive deionization, and ion exchange.
