“…Among these agro-industries, wineries are important pillars of the local economy in Mediterranean countries, including Greece [1]. The amount and complexity of wastes generated by wineries and the management of these wastes is very problematic [2,3]. Additionally, most of these wineries are usually small-sized, scattered throughout the country, and produce byproducts and wastes seasonally.…”

“…In addition, wine production generates large quantities of wastewater that originate from grape processing and washing operations such as grape crushing and pressing, and the rinsing of fermentation tanks, barrels and other equipment and surfaces [5]. Winery wastewater (WW) is characterized by fluctuations in both quality and quantity during the year [2,3,6,7], causing environmental concern in wine-producing countries. WW is characterized by low pH values (in the range of 3-6 (acidic), with the exception of some winemaking stages such as bottling, where pH values increase), low nutrient content [8][9][10], and high organic content, which according the literature is readily biodegradable [2,4,[11][12][13][14].…”

Biotreatment of Winery Wastewater Using a Hybrid System Combining Biological Trickling Filters and Constructed Wetlands

The objective of this work was to determine the ability of a pilot-scale hybrid system to treat real (non-synthetic) winery wastewater. The experimental treatment system consisted of two stages: An attached growth pilot-scale bioreactor (biological trickling filter with plastic support material) was initially used to remove a significant amount of dissolved chemical oxygen demand (d-COD) from winery wastewater, and then a pilot-scale, horizontal subsurface flow constructed wetland (CW) was examined as a post-treatment step for further d-COD removal. Results from the biofilter revealed that the recirculation rate of 1.0 L/min lead to higher d-COD removal rates than that of 0.5 L/min for all feed d-COD concentrations tested (3500, 7500, 9000 and 18,000 mg d-COD/L). Experiments in the CW were performed using feed d-COD concentrations of about 1500 mg/L (equivalent to biofilter effluent when initial filter feed d-COD concentrations are 18,000 mg/L). The wetland polishing stage managed to further remove d-COD and produced effluent concentrations below current legislation limits for safe disposal. Furthermore, the presence of zeolite in CW (one third of the length of CW) enhanced ammonium removal. The experimental results indicate that the combination of a biological trickling filter and a constructed wetland could effectively treat effluents originating from small wineries typical of the Mediterranean region.

“…Methods in place to manage WWW vary, with some wineries treating their WWW on‐site and reusing the effluent for irrigation, while others direct the WWW to municipal wastewater treatment plants (WWTPs) for co‐treatment within their biological treatment systems, if possible .

“…Technologies that can effectively treat WWW have recently been investigated; however, the majority of these focus on emerging technologies at the bench‐ and pilot‐scale . In terms of on‐site treatment, the majority of wineries utilize simple aerobic biological treatment technologies, while constructed wetland (CW) treatment systems are gaining in popularity and have been found to minimize environmental impacts associated with WWW treatment as compared to more conventional activated sludge systems . However, regional assessments of actual full‐scale practices are lacking in the literature, making it difficult to obtain an understanding of regional strategies in place to address WWW treatment needs.…”

The winemaking process produces a large volume of wastewater with highly variable characteristics. Methods in place to manage winery wastewater (WWW) vary, with some wineries treating their WWW on‐site, while others direct the WWW to municipal wastewater treatment plants (WWTPs). Despite the significant presence and growth of the wine industry in the Niagara Region of Ontario, Canada, few data are available regarding the characteristics and treatment of WWW in this geographic region. This work presents a comprehensive review of full‐scale treatment methods currently in place to manage and treat WWW at 53 wineries in the Niagara Region. The most common type of on‐site treatment is the constructed wetland process, providing overall removal rates of >98% for chemical oxygen demand (COD) and >98% for total suspended solids (TSS) for the combined treatment of WWW and site‐generated sanitary sewage. Subsurface effluent discharge is the most widely used disposal strategy, while larger systems treating WWW alone also reuse the effluent for vineyard irrigation. The construction and operation of on‐site treatment systems at wineries does not address all WWW treatment needs, requiring a portion of the WWW to be co‐treated at WWTPs. While full‐scale operating data indicate that anaerobic co‐digestion with municipal sludges is effective (89% COD removal), the co‐digestion capacity is limited. Co‐treatment in the municipal WWTPs' liquid treatment train leads to negative operational and performance impacts. No efficient WWW co‐treatment options, viable in the long‐term, are currently available at municipal WWTPs. Improved co‐treatment strategies are required to address WWW treatment needs in the Niagara Region.

“…The concentration of inorganics such as nitrogen, potassium, phosphates, and sulfates in agricultural lands may also increase.To avoid negative impacts of vinasses on the environment, a number of biological and physico-chemical treatment technologies can be employed before their discharge that are considered to be successful options [4,[12][13][14][15], either singly or in combination. Conventional biological processes using activated sludge are not efficient enough to depollute these wastewaters, and some compounds with antioxidant properties are toxic to many microorganisms, such as those typically found in the aerobic biological treatment process [16,17]. From an energy point of view, the high organic content makes the vinasses well-suitable for the anaerobic fermentation (biomethanation) [18,19].…”

The production of brandy from wine and bioethanol from sugarcane in distilleries generates vinasses, which are effluents that are rich in organic matter. Since they have a high pollution load characterized by high chemical and biological oxygen demands and a dark color, the depollution of these effluents is inevitable. Pt and Ru catalysts supported on titania and zirconia were explored in the catalytic wet air oxidation (CWAO) processing of cognac and sugarcane wastewaters, in batch mode and in a trickle-bed reactor, at a temperature condition of 190 °C and a pressure condition of 70 bar air. The addition of a catalyst promoted total organic carbon (TOC) abatement and the oxidation of ammonium ions formed from organic nitrogen in the effluents to dinitrogen or nitrates. The best results in terms of selectivity to N2 were obtained by using Pt catalysts; a selectivity of 92% to N2 and a TOC removal of 90% were observed in continuous oxidation of the sugarcane vinasse.
