“…According to these results, the color and turbidity can be removed successfully by EC treatment from winery effluents, but the COD concentration remains too high for discharge (i.e. 13810 and 15200 mg L -1 for Al and Fe electrodes, respectively) [31]. Therefore, EC process could be applied as pre-or post-treatment of other treatment technologies, such as a biological treatment that can achieve higher COD removal.…”

“…The internal rate of return for this project was 29.5% and the payback time 4.0 years, suggesting thus the viability of the treatment process. In a recent study of Kara et al [31] the treatment of winery effluents by EC using two different electrodes (Al and Fe) was investigated. The removal efficiency of the COD (influent COD = 25200-28640 mg L -1 ), color (influent value = 6500 Pt-Co) and turbidity (influent value = 2490 NTU) for Fe and Al electrodes were found to be dependent on initial pH, applied current density and operating time.…”

“…There are various physicochemical processes that have been successfully applied for the treatment of real winery effluent, such as chemical precipitation with chelating agents [25], sedimentation with the addition of flocculants [26], coagulation/flocculation [27][28][29] and electrocogualation (EC) [30,31], as shown in Table 2. When comparing the efficiencies of the various processes, attention must be paid due to the fact that the qualitative characteristics of the initial effluents used in each study differ substantially (as shown in Tables 2, 4-6 and Table S1).…”

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.

“…Such result is more promising than the presented by [14], but similar to that observed by [9], both studies in distillery effluent using aluminum electrodes. High levels of clarification can also be observed with both materials in electrocoagulation of baker's yeast wastewater [15] or winery effluent [16]. In the case of aluminum EC, a turbidity increase is observed in the second hour of electrolysis, reaching the minimum value after 4 hours.…”

Sugarcane ethanol production generates considerable quantities of vinasse, its main wastewater. Microalgae cultivation is a promising option for effluent remediation, since the generated biomass can be feedstock for biofuel and bio-based chemical production. Due to vinasse high turbidity, pretreatment is necessary to clarify this effluent, adapting it as a mixotrophic culture medium. In this context, the present research evaluated the integrated process of electrocoagulation (EC) of sugarcane vinasse with aluminum or iron electrodes and subsequent cultivation of green microalgae Desmodesmus subspicatus. Results indicate pH neutralization and high turbidity removal efficiency by EC with both electrode materials. Aluminum EC and subsequent microalgae cultivation removed 66 and 75% of initial total organic carbon and total nitrogen, respectively, with biomass productivity of 1.45 g L-1day-1 and maximum specific growth rate of 0.095 h-1. Microalgae productivity was inferior in vinasse pretreated by iron EC, suggesting possible interference of ferric compounds in the microalgal development.
