Summary: This review summarizes research data on pharmaceutical drugs used to treat the novel SARS-CoV-2 virus, their characteristics, environmental impacts, and the advanced oxidation processes (AOP) used to remove them. The results show that AOPs are a promising solution for minimizing the environmental impact of these compounds. Photocatalysis is currently the main technology used for removing these drugs, but there are limitations in large-scale practical applications. Additionally, the diverse and complex nature of pharmaceuticals in the environment is discussed.

Summary: A continuous flow photochemical pilot plant unit was used to remove VOC from waste gas stream. The efficiency of the system was studied by controlling reaction conditions, detecting intermediates, and analyzing reaction products. The conversion of the model substances depends on the initial concentration of the pollutant, the flow rate, and the type of pollutant. The results showed that the highest conversion was achieved at an initial pollutant concentration of 50 ppmv and a flow rate of 100 m3 center dot h-1. The study provides insights into the degradation pathways of VOCs and presents an effective AOPs system for VOC removal.

Summary: The majority of current wastewater treatment technologies are ineffective in removing pharmaceutical micropollutants, resulting in their discharge into surface water bodies and causing significant harm to fragile ecosystems. The European Commission has published an expansion of legislation for surface water that includes the monitoring and limitation of the discharge of nine pharmaceuticals. Photochemical advanced oxidation processes (AOPs) have shown promise in efficiently removing micropollutants and could potentially reduce the pharmaceutical burden in wastewater. However, there are challenges that limit their widespread use in treatment plants. This review fills the gap in summarizing and assessing the current trends in the utilization of photochemical AOPs for pharmaceutical micropollutant removal in wastewater treatment, representing the first attempt to address this topic.
