“…It should also be kept in mind that-at least at the scientific and technological levels-intensive internal technical discussions take place. For instance, a scientific discussion about the best strategy for the enforcement of wastewater treatment plants has been initiated quite a while ago and is ongoing at a world-wide scale (for examples, see [6,12,23,24,54,55,60,102]. However, it remains questionable whether stakeholder consultations and non-public scientific discussions will lead to a change in the policy response to pharmaceutical contaminants.…”

Background Despite clear-cut scientific evidence for pharmaceutical contaminants causing adverse effects in aquatic life, the regulatory response in Germany has been weak. In principle, there are different policy approaches to address pharmaceutical contaminants: German water protection policies mostly follows a control approach, complemented by end-of-pipe solutions in some German states. The approach leaves the activities of key target groups, such as the pharmaceutical industry, largely unaffected. A stakeholder consultation initiated in 2016 by the German Federal Ministry of the Environment did not lead to significant changes in regulation. Empirical research in political science has shown that analysing the public debate can be helpful in explaining policy responses and, in particular, policy change. This study follows this approach and investigates whether the German policy response to pharmaceutical contaminants can be explained by characteristics of the public debate on the issue. Results A discourse network analysis based on newspaper reporting in Germany was conducted between 2013 and 2017 to investigate the public debate on pharmaceutical contaminants. German newspapers actually paid considerable attention to the issue. In fact, the debate was not controversial, and participating organisations expressed similar views with regard to the risk of the contaminants, the causes of contamination and the approaches to be taken to mitigate the release of contaminants to the environment. The main narrative in the debate was supportive to the current policy approach applied in Germany. There were no concerted efforts by organisations such as environmental organisations or ecological parties to mobilise for an alternative policy approach. Conclusions The low level of polarisation in the policy subsystem and the absence of a strong narrative mobilising a major policy change may explain the persistence of the policy approach to pharmaceutical contaminants applied in Germany. A significant change to the current approach in the near future seems unlikely. Nevertheless, literature in political science shows that a polarised public debate and a strong pro-change actor coalition often preceded policy change. Actors with an interest in stricter regulation might want to reconsider their mobilisation strategies.

“…However, this method still needs more development in comparison with other similar ones. [57] This technique is based on a process called cavitation. During bubble collapse, for a very short time at the center of the bubble, the average temperature ranges from 4500 to 5000 K and the pressure exceeds 1000 atmospheres.…”

Sonophotocatalyticprocess (SPC) is the simultaneous use of ultraviolet radiation (UV), ultrasonic radiation (US), and semiconductor materials as photocatalysts and sonocatalysts for the generation of reactive oxygen species (ROS). These free radicals oxidize several pollutant molecules in various industrial wastewaters. The objective of this review was to compare the papers published on the sonophotocatalytic degradation of different pollutants in the presence of zinc oxide-based particles. The elimination rate of contaminants in this process was compared with individual methods such as sonocatalysis and photo-catalysis. The experimental conditions, including the catalyst dosage, the pollutant concentration, the radiation power, the applied frequency, the initial pH, and the reaction time were further investigated. ZnO nanoparticles are well-known as semiconductor materials with good sonophotocatalytic activity. In general, sonophotocatalysis is emerging as one of the most efficient treatment techniques for degrading the recalcitrant pollutants in the aqueous medium. It is expected that these technologies result in more progressive research with the most degradation efficiency.

“…These radicals can oxidize toxic organic components and pathogens contained in WW [5,12,33] that cannot be degraded in conventional WWTPs [6,26]. Thus, the implementation of AOPs allows for the regeneration and reuse of WW, being an alternative to reduce water stress in some regions of the world [14,34,35], particularly in those where the scarcity of this natural resource is recurrent.…”

In this work, the recent trends in the application of the sulfate radical-based advanced oxidation processes (SR-AOPs) for the treatment of wastewater polluted with emerging contaminants (ECs) and pathogenic load were systematically studied due to the high oxidizing power ascribed to these technologies. Additionally, because of the economic benefits and the synergies presented in terms of efficiency in ECs degradation and pathogen inactivation, the combination of the referred to AOPs and conventional treatments, including biological processes, was covered. Finally, the barriers and limitations related to the implementation of SR-AOPs were described, highlighting the still scarce full-scale implementation and the high operating-costs associated, especially when solar energy cannot be used in the oxidation systems.
