The process behind recovering high-value phenolic compounds in vinasse, present at a concentration within the region of 600 mg L , is likely to be economically not feasible (Santos et al, 2003).…”

Ethanol production from sugarcane in Brazil is a well-established industry, with relatively simple operations and high yield. The ethanol primarily serves as a renewable fuel blending with gasoline and diesel to increase the energy security in Brazil. Several environmental concerns are emerged around the by-products from this industry. Vinasse, the liquid fraction generated from the rectification and distillation operations of ethanol, is a sulfur-rich, low pH, dark-colored, and odorous effluent, produced at volumes as high as 20-fold of ethanol. Traditional wastewater treatments, such as bioprocessing, advanced oxidative processes, anaerobic digestion (AD), and chemical-based processes, have been applied to vinasse management. Despite most of its utilization being in fertirrigation practices, vinasse may represent a key factor in enhancing profitability and environmental outcomes of a sugarcane-to-ethanol plant. The application of some upgrade solutions to sugarcane-derived vinasse may represent additional sources of energy, production of animal feed components, and reduction in water consumption within a plant. The use of mature technologies, yet not widespread in the sugarcane-to-ethanol industry, could help attenuate environmental concerns. Oxidation and chemical processes, AD, and microbial fermentation have been presented as alternative impactful alternatives to (i) reduce its organic and mineral load, converting it to a feedstock with fewer environmental applications when applied as fertilizer and (ii) to convert organic matter and nutrients to a nutritious biomass, simultaneously increasing water reclamation potential by plants. This mini-review article provides a critical and comprehensive summary of the alternatives developed or under development to vinasse management.

The winemaking industry produces large volumes of wastewater that pose an environmental threat if not treated correctly. The increasing numbers of wineries and the demand for wine around the world are adding to the growing problem. The vinification process includes all steps of the winemaking process, from the receipt of grapes to the final packaged product in the bottle. To fully understand all the aspects of winery wastewater it is important to know the winemaking processes before considering possible treatments. Winemaking is seen as an art and all wineries are individual, hence treatment solutions should be different. Furthermore, wastewater also differs from one winery to another regarding its volume and composition and therefore is it vital for a detailed characterisation of the wastewater to fully understand the problem before managing it. However, prevention is better than cure. There are a number of winemaking practices that can help lower the volume of the wastewater produced to decrease the work load of the treatment system and increase the efficiency of treatment.

“…Research has been carried out on the treatment of distilleries wastewater. Various conventional methods have been adopted such as biological flocculation (Zhang et al 2009), nanofiltration (Rai et al 2008), activated carbons (Satyawali and Balakrishnan 2007), bioelectrochemical process (Mohanakrishna et al 2010), ozonation-based process (Sreethawong and Chavadej 2008;Lucas et al 2010;Asaithambi et al 2012), electro-oxidation (Piya-areetham et al 2006;Thakur et al 2009), membrane-based nanofiltration and reverse osmosis (Nataraj et al 2006) and electrocoagulation (Ponselvan et al 2009). However, conventional methods found to be techno-economically non-feasible for the treatment of organic pollutant present in the effluent.…”

The treatment of distillery effluent was investigated experimentally by various advanced oxidation processes such as Fenton and ozone with different combination of UV and H 2 O 2 system. The effect of operating parameters such as hydrogen peroxide concentration, initial effluent pH and Fe 2? concentration on Fenton system for the percentage color and chemical oxygen demand removal has been studied. The energy per order was also calculated for the advanced oxidation process. The ozone-photoFenton system has been observed that 100 % color and chemical oxygen demand removal compared with other process studied in the present investigation within 4 h of treatment time. Electrical energy per order has been calculated for all the process and found that ozone-photoFenton shows lesser energy consumption of about 0.01 kWh/m 3 order 1 , for the complete color and chemical oxygen demand removal.
