“…The recovery of water and nutrients contributes to the circular economy perspective through the reduced need for both chemical fertilizers and freshwater supply in the agricultural sector. This approach allows to transform WWTPs in sustainable technological systems (Leyva-Diaz et al 2020 ; Qu et al 2019 ).…”

The present work is a preliminary study on the potential of low-frequency ultrasound irradiation coupled with O 3 process for the disinfection of a primary effluent from a municipal wastewater treatment plant preserving nutrient levels (in particular nitrogen and phosphorous), for its possible reuse in civil, industrial, and agricultural sectors. The treated water could be reused, after appropriate dilution, contributing to the circular economy perspective and reducing the need for both chemical fertilizer addition and freshwater supply. The effect of different specific ultrasonic energies and ozone doses was assessed on a bench-top system, composed of an ultrasonic reactor and a semi-batch ozonation vessel. The results showed that the combined US-O 3 process produces a good removal efficiency regarding soluble Chemical Oxygen Demand, sCOD (ca. 60%), anionic surfactants (ca. 50%), and formaldehyde (ca. 50%), and an optimal abatement for Methylene Blue Active Substances (MBAS, > 90%). The process also reached high disinfection performances, obtaining 4 logs for E. coli and 5 log abatement for Total Coliforms. The high removal efficiency is matched by an outstanding retention of nutrients (total nitrogen and orthophosphate) highlighting a high potential value for agricultural reuse of the treated primary effluent, with possible significant saving of chemical fertilizers. It was concluded that low-frequency ultrasound pretreatment, combined with ozonation, could be a useful process for primary effluent recovery for several purposes. Further studies are expected to be planned and executed to evaluate system scale-up feasibility.

“…It was obvious that the FF and chromatogram of municipal wastewater were quite different from those of water body in SJ-BHGC. In recent years, Jiangsu Province has started to put forward more stringent effluent standards for local municipal WWTPs ( Qu et al, 2019 ). To response to the requirements of the government, many municipal WWTPs have reformed their wastewater treatment processes to enhance the removal rate of pollutants.…”

“…Compared with the European Union and the United States standards, China's wastewater discharge standards still have shortcomings, and there exist many challenges in this field. For this reason, the Chinese government is putting more effort into exploring new wastewater treatments [66]. In the United States, the potential use of municipal reclaimed water in the power sector has led to an increase in the number of publications about wastewater reclamation treatments.…”

Background: Water is a scarce resource and is considered a fundamental pillar of sustainable development. The modern development of society requires more and more drinking water. For this cleaner wastewater, treatments are key factors. Among those that exist, advanced oxidation processes are being researched as one of the sustainable solutions. The main objective of this manuscript is to show the scientific advances in this field. Methods: In this paper, a systematic analysis of all the existing scientific works was carried out to verify the evolution of this line of research. Results: It was observed that the three main countries researching this field are China, Spain, and the USA. Regarding the scientific collaboration between countries, three clusters were detected—one of Spain, one of China and the USA, and one of Italy and France. The publications are grouped around three types of water: industrial, urban, and drinking. Regarding the research, 15 clusters identified from the keywords analyzed the advanced oxidation process (alone or combined with biological oxidation) with the type of wastewater and the target pollutant, removal of which is intended. Finally, the most important scientific communities or clusters detected in terms of the number of published articles were those related to the elimination of pollutants of biological origin, such as bacteria, and of industrial nature, such as pesticides or pharmaceutical products.
