Possible Pollution of Surface Water Bodies with Tequila Vinasses
Water, 2023 The aim of this study was to evaluate the water quality in two streams of the Valles region of Jalisco, Mexico and fully determine if they are being used as tequila vinasse disposal sites. Three sampling campaigns were carried out at eight different points of the two streams that run near tequila factories (TFs). Different physicochemical parameters of

Anaerobic treatment of Tequila vinasses in a CSTR-type digester
Biodegradation, 2009 Tequila industries in general produce great volumes of effluents with high pollutant loads, which are discharged (untreated or partially treated) into natural receivers, thus causing severe environmental problems. In this contribution, we propose an integrated system as a first step to comply with the Mexican ecological norms and stabilize the ...

ProcessesThe tequila industry faces several environmental challenges due to its high yields of contaminants, especially tequila distillation stillage or tequila vinasses, with ten to twelve liters produced per liter of tequila. All treatments aim to shorten retention times to avoid the need for large equipment or new facilities and the saturation of residues ...

Tequila vinasses acidogenesis in a UASB reactor with Clostridium predominance. [PDF]
Springerplus, 2015 Tequila vinasses represent an acidic, highly concentrated pollutant effluent generated during the distillation step of Tequila production. Although acidogenesis of Tequila vinasses has been reported for some reactor configurations, a characterization of the bacteria present during this metabolic process is lacking in the literature. Hydraulic retention

WaterThe aim of this study was to evaluate a natural coagulant, Moringa oleifera seeds (MOC), to reduce the color concentration in treated tequila vinasses (TVs). TV-A was the effluent of horizontal subsurface flow wetlands (HSSFW); TV-B was the effluent of vertical up-flow wetlands (VUFW); and TV-C was the effluent of vertical down-flow constructed ...

, 2007 This study consisted of three experiments designed to evaluate the practicality of using a cationic polyacrylamide (PAM) polymer flocculant to reduce commonly used aquatic pollution indicators in tequila vinasses. A first experiment with a 2 x 2 factorial arrangement was used to observe the effects on vinasses of five different concentrations of PAM ...
