“…Membrane bioreactors are widely used in the secondary treatment of WWTPs; these are composed of a suspended reactor, with membrane separation (micro-filtration or ultrafiltration) to perform biological treatment and solids removal [68]. In the bioreactor, the wastewater that leaves the biological reactor, passes through the membranes where compounds larger than its pore are retained thanks to the negative pressure induced by a pump; this makes possible the separation between water and biomass, where the latter Technologies in Wastewater Treatment Plants for the Removal of Antibiotics, Resistant Bacteria and Antibiotic Resistance Genes: a Review of the Current Literature remains in the bioreactor [69].…”

This study aimed to evaluate the efficiency of technologies for removing antibiotics, antibiotic-resistant bacteria and their antibiotic resistance genes, and the countries where they have been developed. For this purpose, was conducted a systematic review to identify the tertiary treatments to remove the above-mentioned pollutants. The ScienceDirect and Scopus databases were used as sources of information, taking into account only experimental research from 2006 to 2019 and technologies with removal rates higher than 70% to the information analyses. From the analysis of 9 technologies evaluated, in a set of 47 investigations, photo-Fenton, and electrochemical treatments were found to be the most efficient in the removal of antibiotics; gamma radiation and photocatalysis with TiO2 and UV revealed better results in the removal of resistant microbial agents and their resistance genes, with efficiencies of 99.9%. As one of the largest producers and consumers of antibiotics, China appears to be the country with the most scientific research on the area. The importance of innovation in wastewater treatment processes to achieve better results in the remotion of antibiotics, antibiotic-resistant bacteria, and their resistance genes is highlighted, given the effects on the aquatic ecosystems and public health.

“…As with composting, this process entails the stabilization of the OM and may then influence the bioavailability of organic pollutants by promoting sorption processes [56]. Relevantly, physical adsorption was identified as a key mechanism for the removal of antibiotic residues from organic materials [214]. The anaerobic digestion of organic waste may be carried out under mesophilic or thermophilic conditions, the former being the most widely applied process [215].…”

Potential Benefits and Risks for Soil Health Derived From the Use of Organic Amendments in Agriculture

2019

The use of organic amendments in agriculture is a common practice due to their potential to increase crop productivity and enhance soil health. Indeed, organic amendments of different origin and composition (e.g., animal slurry, manure, compost, sewage sludge, etc.) can supply valuable nutrients to the soil, as well as increase its organic matter content, with concomitant benefits for soil health. However, the application of organic amendments to agricultural soil entails a variety of risks for environmental and human health. Organic amendments often contain a range of pollutants, including heavy metals, persistent organic pollutants, potential human pathogens, and emerging pollutants. Regarding emerging pollutants, the presence of antibiotic residues, antibiotic-resistant bacteria, and antibiotic-resistance genes in agricultural amendments is currently a matter of much concern, due to the concomitant risks for human health. Similarly, currently, the introduction of microplastics to agricultural soil, via the application of organic amendments (mainly, sewage sludge), is a topic of much relevance, owing to its magnitude and potential adverse effects for environmental health. There is, currently, much interest in the development of efficient strategies to mitigate the risks associated to the application of organic amendments to agricultural soil, while benefiting from their numerous advantages.

“…For example, during spring and winter when infectious diseases spread rapidly, antibiotic consumption and discharge into aquatic environments increases. Those antibiotics accumulate in activated sludge; during summer, a peak concentration of around 9481.43 ng/g for the fluoroquinolone ofloxacin has been monitored in water bodies [18].…”

“…Microfiltration (MF)/ultrafiltration (UF) MBRs are techno-economically feasible and a most promising option in wastewater treatment. In MBRs, flatsheet or hollowfiber (HF) membranes are immersed into a bioreactor to achieve excellent and consistent micropollutant removal, compared to conventional activated sludge systems [3,14,18,[43][44][45]. The worldwide suppliers and key players of MBRs include SUEZ Water Technologies & Solutions (formerly GE Water & Process Technologies) (France), Kubota (Japan), Beijing Origin Water Technology (China), Evoqua Water Technologies (US), Mitsubishi Chemical Aqua Solutions (Japan), Toray Industries (Japan), CITIC Envirotech Ltd.

Removal of Organic Micro-Pollutants by Conventional Membrane Bioreactors and High-Retention Membrane Bioreactors

et al. 2020

The ubiquitous presence of organic micropollutants (OMPs) in the environment as a result of continuous discharge from wastewater treatment plants (WWTPs) into water matrices—even at trace concentrations (ng/L)—is of great concern, both in the public and environmental health domains. This fact essentially warrants developing and implementing energy-efficient, economical, sustainable and easy to handle technologies to meet stringent legislative requirements. Membrane-based processes—both stand-alone or integration of membrane processes—are an attractive option for the removal of OMPs because of their high reliability compared with conventional process, least chemical consumption and smaller footprint. This review summarizes recent research (mainly 2015–present) on the application of conventional aerobic and anaerobic membrane bioreactors used for the removal of organic micropollutants (OMP) from wastewater. Integration and hybridization of membrane processes with other physicochemical processes are becoming promising options for OMP removal. Recent studies on high retention membrane bioreactors (HRMBRs) such as osmotic membrane bioreactor (OMBRs) and membrane distillation bioreactors (MDBRs) are discussed. Future prospects of membrane bioreactors (MBRs) and HRMBRs for improving OMP removal from wastewater are also proposed.
