“…Biological treatment uses a variety of microorganisms to biodegrade pollutants and eliminate EC (Nguyen et al, 2021 ). There are some techniques dedicated to the removal of BOD 5 , COD, and TSS, others for the elimination of bacteria, PhAC, and virus inactivation (Sá et al, 2021 ; Alam et al, 2021 ; Panneerselvam & Priya, 2021 ; Pourakbar et al, 2022 ). Many researchers have studied the performance of biological treatments that are widely used technologies for wastewater treatment in general and frequently implemented for HWW treatment such as ASP, MBR, constructed wetlands (CW), and moving bed bioreactors (MBBR) (Mir-Tutusaus et al, 2021 ; Alarjani, 2021 ; Sossalla et al, 2021 ; Leiviskä & Risteelä, 2022 ).…”

Health care institutions generate large volumes of liquid effluents from specific activities related to healthcare, analysis, and research. Their direct discharge into the environment has various negative effects on aquatic environments and human health, due to their high organic matter charges and the presence of various emerging contaminants such as disinfectants, drugs, bacteria, viruses, and parasites. Moreover, hospital effluents, by carrying antibiotics, contribute to the development of antibiotic-resistant microorganisms in the environment. This resistance has become a global issue that manifests itself variously in different countries, causing the transmission of different infections. In this respect, an effort is provided to protect water resources by current treatment methods that imply physical–chemical processes such as adsorption and advanced oxidation processes, biological processes such as activated sludge and membrane bioreactors and other hybrid techniques. The purpose of this review is to improve the knowledge on the composition and impact of hospital wastewater on man and the environment, highlighting the different treatment techniques appropriate to this type of disposal before discharge into the environment.

“…Various studies have concluded that UV radiation achieves better contaminant removal efficiencies compared to the use of sunlight [67,96]; however, ferricarboxylate complexes are photoactive at wavelengths up to 600 nm, which allows the application of the photo-Fenton process in the visible region of the spectrum, which makes this process more attractive for application on an industrial scale compared to other similar processes, such as electro-Fenton [121]. On the other hand, the intensity affects the efficiency of the process proportionally [122,123], which implies that the location of the photo-Fenton processes must be chosen strategically in places with high solar radiation.…”

Currently there is a growing concern about the presence of emerging contaminants (EC) in water bodies and their potential ecotoxicological effects. Pharmaceuticals, a type of EC, are widely distributed in the environment and their main entry is through wastewater from treatment plants, since these systems are not designed to remove EC. In this sense, the photo-Fenton process, an advanced oxidation process, has proven to be highly efficient in degrading new potentially harmful contaminants. However, this process is affected by multiple factors, which makes it necessary to implement a methodological strategy to optimize the photo-Fenton process. Within these, the Taguchi method provides robust and low-cost solutions with the least number of experiments, providing knowledge of the contribution of each of the factors studied to the response variable. In addition to the above, the Taguchi method can be coupled to a Grey relational analysis (Grey–Taguchi method), which will allow the optimization of more than one response variable at the same time. This paper discusses the parameters that affect the photo-Fenton process and the application of designs of experiments to optimize the process.

“…Concerning solar photo-Fenton application as post-treatment of CAS effluent, only a stimulation of root elongation was detected within 90 min ( Freitas et al, 2017 ). Although results obtained from this bioassay provide essential information considering the reuse of treated wastewater for irrigation in agriculture ( Sobrero and Ronco, 2009 ), the classification of toxic effects concerning the RGI has only been applied in a few studies for environmental matrices such as: synthetic wastewater before and after UASB system ( Rodrigues-Silva et al, 2022b ), MSE ( Freitas et al, 2017 ), pesticides contaminated water ( Utzig et al, 2019 ), antibiotic contaminated water ( Rodrigues-Silva et al, 2022a ), and clinical laboratory hospital wastewater ( Sá et al, 2021 ).…”
