“…Finally, solar photo-Fenton oxidation at bench scale was proved to be very efficient for the treatment of the winery effluents which were pretreated by a MBR, reaching an additional COD removal of approximately 70% (COD after MBR pre-treatment = 120 mg L -1 ), corresponding to a residual COD value of 33 mg L -1 [97]. The major part of COD was removed during first 30 min of chemical posttreatment (58%), while an additional 10% of COD was removed by increasing the treatment time to 90 min, after which a plateau was reached.…”

“…Furthermore, the combination of an advanced biological treatment, such as an MBR with solar Fenton oxidation, seems to be a very promising process, both for the elimination of the winery wastewaters' organic load (residual COD < 30 mg L -1 ), as well as its ecotoxicity, even at pilot/industrial scale [22,97]. The evaluation of the potential toxicity of the winery wastewater after each treatment process remains a knowledge gap in the literature, which requires further investigation.…”

Winery wastewater is a major waste stream resulting from numerous cleaning operations that occur during the production stages of wine. The resulting effluent contains various organic and inorganic contaminants and its environmental impact is notable, mainly due to its high organic/inorganic load, the large volumes produced and its seasonal variability. Several processes for the treatment of winery wastewater are currently available, but the development of alternative treatment methods is necessary in order to (i) maximize the efficiency and flexibility of the treatment process to meet the discharge requirements for winery effluents, and (ii) decrease both the environmental footprint, as well as the investment/operational costs of the process. This review, presents the state-of-the-art of the processes currently applied and/or tested for the treatment of winery wastewater, which were divided into five categories: i.e., physicochemical, biological, membrane filtration and separation, advanced oxidation processes, and combined biological and advanced oxidation processes. The advantages and disadvantages, as well as the main parameters/factors affecting the efficiency of winery wastewater treatment are discussed. Both bench- and pilot/industrial-scale processes have been considered for this review.

BACKGROUND Pharmaceutically active compounds, emerging extensively in ecosystems as pollutants, have become an important environmental and public health issue, since they can contaminate drinking water and pose threats to wildlife and human health. As a result, efforts should be made to develop methods to inactivate or eliminate this class of substance in the environment. RESULTS The photocatalytic degradation of psychoactive drug Fluvoxamine has been investigated. In the case of heterogeneous photocatalytic oxidation, the effect of TiO2 P25 concentration (0.1–1 g L‐1), initial concentration of H2O2 (0.25–0.2 g L‐1) and Fe3+ (0.00175–0.014 g L‐1) and pH of the solution on initial reaction rates were evaluated, while for homogeneous photocatalytic oxidation the effect of the amount of H2O2 (0.25–0.2 g L‐1) and Fe3+ (0.00175–0.014 g L‐1) were investigated. In addition, the conversion of the heteroatoms in the FVX molecule to inorganic ions (NO3‐, NH4+, F‐) during the photocatalytic process has been observed and phytotoxicity testing, using three plant species, was carried out in order to examine the effect of photocatalytic oxidation on the toxicity of FVX. CONCLUSION According to the results presented in this study, both heterogeneous and homogeneous photocatalytic oxidation is an efficient methodology for FVX degradation. © 2017 Society of Chemical Industry
