“…A special attention should be paid to the negative values of RE when the concentration of PCs increases after the treatment process. This phenomenon has been already described in previous studies [29,[39][40][41]. We attribute it to the removal of naproxen from the pretreated BC after 2 h incubation, as well as ketoprofen and diclofenac after 7 d incubation (Figs.…”

“…Wang et al [42] reported about the sorption of 14 PCs at comparatively low concentrations on rice straw BC. It was shown that the sorption was promoted by the porosity of sorbent and suppressed by the electron-donating nature of PC molecules [41]. In this respect, the effects of 12 molecular characteristics on the removal of PCs were evaluated by performing regression analysis.…”

The aim of this study was to evaluate the effectiveness of wood-derived biochar for the removal of 18 pharmaceutical compounds (PCs) from untreated municipal wastewater (WW). The WW samples were analyzed by an HPLC-Q-Orbitrap-HRMS method. Two aliquots of WWs were incubated with biochar sorbent for 2 h and 7 d. The highest absolute removal of PCs was achieved for ibuprofen and caffeine (2.6 and 13.2 mg L-1 after 7 d, respectively). The highest removal efficiency after 2 h incubation was detected for erythromycin (72.0% ± 12.7 %) while lower degree of removal was observed for other compounds with much higher initial concentrations. The results indicated that a 2 h sorption process on biochar may be insufficient and 7 d incubation is preferred for quantitative removal of xylazine, metoprolol, and azithromycin. However, the sorption of ketoprofen, diclofenac, ibuprofen, sulfamethoxazole, and simvastatin on biochar was more effective during the first 2 h than during the following 7 d. Regression analysis revealed a strong correlation (R 2~0 .9) between the absolute amounts of the removed PCs and their initial concentrations. In this respect, the removal of the last traces of PCs from WW is expected to present technological challenges.

“…Employees of the tourism industry are to be added to this floating population, as the former come to the islands every summer from different parts of Spain to fill vacant positions. The average number of people employed at hotels and aparthotels reaches 176,727 in the summer months, while the lowest figure is 73,198 in the low season [53]. The increasing demand and the high concentration of visitors create a complex situation with regard to managing the potential impacts that tourist activity generates on the natural environment.…”

“…It is here that reusing wastewater becomes relevant, as it allows increasing the available water resources while decreasing the impact caused by the pollutant load present in wastewater [69]. It should be noted that for safe reuse, water treatment schemes must meet high quality standards including removal of persistent micropollutants [70,71] some of which have been shown to persist after some wastewater treatments [72][73][74][75][76].…”

Tourist activity has a number of impacts on the destinations in which it takes place, among which are the environmental ones. A particular problem is the increase in water demand and wastewater production, which can compromise the balance of ecosystems. As many authors point out, there is a research gap in the comparative analysis between available water resources and the demand associated with tourism. In this respect, the main objective of this work is, on the one hand, to assess the water needs linked to the tourism industry and the capacity of natural resources to meet such a demand and, on the other hand, to estimate the economic cost of the water supply associated with the growing tourist demand in a territory, such as the island of Ibiza in Spain. It has been determined that the resources available are not sufficient to meet the water demand of the resident population at this destination, which is why it is necessary to resort to producing desalinated water. Therefore, the additional requirements associated with tourism must be met fully with desalinated water, which results in an increased cost of water management for the region. This paper also points at water losses in distribution networks and tourism seasonality as two phenomena that aggravate this issue.

“…Some results can be negative efficiency. For example, González-Pérez et al (2017) have worked on the system that has been operated with complex nitrification and ensured that the biodegradable organic material due to circulation is effectively retained [66]. By reducing the concentration increase in the diclofenac (DCF) in the aerobic bioreactor, negative removal efficiencies for DCF have been obtained.…”

In the recent past years, micropollutants that are pharmaceutically active compounds (PhACs) have been used extensively and have been discovered in raw sewage, wastewater treatment plants, effluents, surface, and groundwater with concentrations from ng/L to several μg/L. Even though many of these compounds are still not determined online, monitoring technology improvements progressed. Today's wastewater treatment plants are not constructed to remove these micropollutants yet. Conventional activated sludge processes are used in the treatment of municipal wastewater but are not specifically designed for the removal of micropollutants. The remaining pharmaceuticals mix into surface waters. At that stage, they can adversely affect the aquatic environment and may cause issues for drinking water production. As the conventional methods are insufficient for removing the micropollutants, other alternative treatment methods can be applied such as coagulation-flocculation, activated carbon adsorption (powdered activated carbon and granular activated carbon), advanced oxidation processes, membrane processes, and membrane bioreactor. It has been observed that membrane bioreactor (MBR) can achieve higher and more consistent micropollutants removal. The removal of micropollutants is based on physicochemical properties of micropollutants and the conditions of treatment. Due to recent technical innovations and cost reductions of the actual membranes, the membrane bioreactor takes attention. In this study, membrane bioreactor experiments for micropollutants in drinking use, wastewater, and surface waters were investigated in detail based on literature investigations, and the feasibility of this method was evaluated.
