“…UV disinfection has the advantage that it is compact, does not produce chemical residues, and is effective in reducing ARGs; however, it can cause regrowth and photoreactivation of pathogenic bacteria [ 76 ]. Currently, various new technologies, including a membrane-separation process, are being developed to improve the ability of STPs to reduce levels of ARB and ARGs [ 9 , 76 , 77 ]. The membrane-separation process has shown the most promising results in reducing both ARB and ARGs, although it is expensive [ 9 ].…”

Review of Antimicrobial Resistance in Wastewater in Japan: Current Challenges and Future Perspectives

Antimicrobial resistance (AMR) circulates through humans, animals, and the environments, requiring a One Health approach. Recently, urban sewage has increasingly been suggested as a hotspot for AMR even in high-income countries (HICs), where the water sanitation and hygiene infrastructure are well-developed. To understand the current status of AMR in wastewater in a HIC, we reviewed the epidemiological studies on AMR in the sewage environment in Japan from the published literature. Our review showed that a wide variety of clinically important antibiotic-resistant bacteria (ARB), antibiotic resistance genes (ARGs), and antimicrobial residues are present in human wastewater in Japan. Their concentrations are lower than in low- and middle-income countries (LMICs) and are further reduced by sewage treatment plants (STPs) before discharge. Nevertheless, the remaining ARB and ARGs could be an important source of AMR contamination in river water. Furthermore, hospital effluence may be an important reservoir of clinically important ARB. The high concentration of antimicrobial agents commonly prescribed in Japan may contribute to the selection and dissemination of AMR within wastewater. Our review shows the importance of both monitoring for AMR and antimicrobials in human wastewater and efforts to reduce their contamination load in wastewater.

“…[168] The first, simplest and most popular EAOP is AO, where organic compounds can be oxidized directly on the surface of the anode by electron transfer and indirectly oxidized by * OH weakly physiosorbed on the surface of the anode and/or agents in the bulk solution such as an active chlorine species, O 3 , persulfates and/or H 2 O 2 . [145,183] Some EAOP, such as heterogeneous photocatalysis, radiolysis and other advanced techniques, also use chemical reducers that allow transformations of toxic contaminants not susceptible to oxidation. This includes metal ions or halogenated compounds.…”

“…These variables include electrode material, which plays a fundamental role in the generation of an oxidizing species for the transformation or degradation of pollutants in solution. [145] Electrodes are modified with transition metals with different compositions, to target the generation of oxidizing species such as ( * OH, * OOH, H 2 O 2 and O 3 ) specifically required to carry out advanced oxidation processes. [202][203][204] As previously observed the efficiency of contaminant removal is closely related to the operating conditions and, above all, to the selected electrode materials.…”

Detection and Treatment of Persistent Pollutants in Water: General Review of Pharmaceutical Products

Environmental problems of great complexity arise from the enormous number of toxic substances that are generated by anthropogenic activities. Seemingly, society encounters new issues every day thus these problems seem to be endless. Now in the face of the COVID‐19 pandemic and the SARS‐CoV‐2 crisis, a large number of emerging treatment compounds generated by pharmaceutical companies worldwide makes future issues even more treacherous. For this reason, there is an increasing need to detect and treat emerging compounds to prevent them from becoming persistent pollutants. This review describes the advances in the use of electrochemical sensors with modified carbon‐based electrodes among other issues, to determine antibiotics, anti‐inflammatories and antidepressants levels in the environment. It further explores technologies suggested for cleaning wastewater polluted by pharmaceutical products using biological or advanced oxidation processes including photolysis, photocatalysis, microwave heating, ultrasound, Fenton, electro‐Fenton, photoelectro‐Fenton and various combined treatments.

The inefficiency of conventional biological processes to remove pharmaceutical compounds (PhCs) in wastewater is leading to their accumulation in aquatic environments. These compounds are characterized by high toxicity, high antibiotic activity and low biodegradability, and their presence is causing serious environmental risks. Because much of the PhCs consumed by humans are excreted in the urine, hospital effluents have been considered one of the main routes of entry of PhCs into the environment. In this work, a critical review of the technologies employed for the removal of PhCs in hospital wastewater was carried out. This review provides an overview of the current state of the developed technologies for decreasing the chemical risks associated with the presence of PhCs in hospital wastewater or urine in the last years, including conventional treatments (filtration, adsorption, or biological processes), advanced oxidation processes (AOPs) and electrochemical advanced oxidation processes (EAOPs).
