This paper thoroughly examines the biological treatment of hospital wastewater,focusing on organic pollutant concentrations, the presence of pharmaceuticalsubstances, removal rates, and pathogenic microorganisms. Conventional andinnovative treatment methods were analyzed, such as activated sludge systems,membrane bioreactors (MBR), aerobic granular sludge systems, artificial wetlands,and anaerobic processes (AnMBR). In addition, some cases where biologicalprocesses are combined with advanced oxidation processes (AOPs), ozonation, andultraviolet radiation (UV) were also examined. The removal rates for key indicators(COD, BOD, TN, TP, TSS) were compared, as well as the performance againstpharmaceutical compounds, for example, carbamazepine, ibuprofen, ciprofloxacin,and lorazepam. Particular emphasis was placed on the presence and risk ofpathogens such as E. coli, Klebsiella, Giardia and Cryptosporidium.The results showed significant differences in the effectiveness of methods, withinnovative technologies outperforming others in the removal of pharmaceuticals and pathogens, although they come with increased costs.The reported yields range from 0-100%, with this range being due to the different regions and populations studied.Only one value is observed at -2%, which indicates an increase in the concentration of the pharmaceutical substance. As for pathogens, there are no removal values as the research did not focus on this field. Future recommendations include the development of hybrid technologies, the use of sensors for online monitoring, staff training, and the introduction of incentives for investment in advanced systems. In conclusion, achieving high removal rates and protecting public health requires a combination of technologies and policies tailored to the specificities of each unit.
