“…Pollutants from pharmaceutical products can be categorized into antibiotics, non-steroidal antiinflammatory drugs (NSAIDs), anticonvulsants or anti-seizures, and stimulants [8]. Pharmaceutical product pollutants are able to produce resistant bacteria and alter the metabolic system of living things, thus making them harmful to the receiving environment [9].…”

Recently identified compounds and chemicals that are harmful to the environment and pose a major risk to human health, known as emerging pollutants (EPs), are receiving increasing attention today. The main basis for this study is the absence of studies that discuss the presence of anti-inflammatory and anti-pain medicines in river water in Surabaya. Based on the study results, it was found that the overall average paracetamol concentration was 333 μg/L in Mas River and 430 μg/L in Surabaya River. Meanwhile, the ibuprofen concentration was not detected at all sampling points. This can be caused by the levels of ibuprofen, which are very small or below the detection limit. River water quality standards are regulated in Appendix VI of Government Regulation of the Republic of Indonesia Number 22 of 2021. On average, other water parameters that were also monitored, namely BOD, COD, nitrate, and phosphate, exceed the class II quality standards. Meanwhile, the pH and temperature parameters are within the class II quality standards range. Further research is needed to determine the presence of EPs in Surabaya rivers. This research can be a useful reference for further research.

“…Antibiotics are discharged into wastewater from healthcare facilities by patients' excretion and discarding leftover medication. Moreover, large amounts of antibiotics are produced during the pharmaceutical manufacturing process and are dumped into wastewater, which presents a serious environmental risk (Larsson et al 2007, Khan et al 2023. Hospitals' contribution to the pharmaceutical consignment in wastewater is difficult to assess because most people use medications and contraceptives.…”

Antibiotic contamination of natural resources and the receiving environment is of great concern. This brief discussion consists of the sources regarding antibiotic contamination and the analysis of several viable methods of removing antibiotic substances. The sources include domestic discharges, agricultural runoff, and pharmaceutical manufacturing effluents. Antibiotics are classified as emerging contaminants attributed to their persistence in the environment. Antibiotics and their metabolites enter the environment through human and animal urine and faeces. Persistent pollutants are introduced to aquatic ecosystems as they pass the wastewater treatment process. The overuse of antibiotics has led to the emergence of bacteria and genes resistant to antibiotics in the environment. This study provides a descriptive overview of antibiotic sources in the environment, their harmful effects, analytical techniques for its detection in wastewater, related challenges in monitoring antibiotic contamination in water, and recently used techniques for its removal from wastewater and problems associated with current strategies. The study also underscores the importance of understanding the sources and learning how to successfully apply methods to minimise the effects of antibiotic contamination in wastewater.

“…A CW is a green, sustainable wastewater treatment technology with striking features such as ecologically restorative functions, low operational costs, and low energy consumption, and it has been widely used globally for various wastewater treatments, especially in recent years [2,7,32,33]. In CWs, the substrate, plants, and microbial community all collaborate to eliminate contaminants from wastewater.…”

“…Furthermore, when Fe 2+ is present in the system, the Fenton reaction will produce •OH with significant oxidizing power, hence enhancing the potential ability of hospital wastewater to remove pharmaceuticals [43,94]. Aeration may affect the redox potential of wetland ecosystems, which, in turn, affects the degradation of drugs by microbes [32]. Auvinen et al [87] developed a CW and applied continuous aeration to treat hospital wastewater; consequently, the removal rates of metformin and valsartan were dramatically boosted (99 ± 1% for metformin versus 68 ± 32% and 99 ± 1% for valsartan versus 17 ± 19%, respectively).…”

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has spread across the globe since the end of 2019, posing significant challenges for global medical facilities and human health. Treatment of hospital wastewater is vitally important under this special circumstance. However, there is a shortage of studies on the sustainable wastewater treatment processes utilized by hospitals. Based on a review of the research trends regarding hospital wastewater treatment in the past three years of the COVID-19 outbreak, this review overviews the existing hospital wastewater treatment processes. It is clear that activated sludge processes (ASPs) and the use of membrane bioreactors (MBRs) are the major and effective treatment techniques applied to hospital wastewater. Advanced technology (such as Fenton oxidation, electrocoagulation, etc.) has also achieved good results, but the use of such technology remains small scale for the moment and poses some side effects, including increased cost. More interestingly, this review reveals the increased use of constructed wetlands (CWs) as an eco-solution for hospital wastewater treatment and then focuses in slightly more detail on examining the roles and mechanisms of CWs’ components with respect to purifying hospital wastewater and compares their removal efficiency with other treatment processes. It is believed that a multi-stage CW system with various intensifications or CWs incorporated with other treatment processes constitute an effective, sustainable solution for hospital wastewater treatment in order to cope with the post-pandemic era.
