Modeling pH and temperature effects on the anaerobic treatment of tequila vinasses
Journal of Chemical Technology & Biotechnology, 2020AbstractBACKGROUNDAn unstructured mathematical model is proposed to evaluate the effect of key variables on the anaerobic digestion of tequila vinasses and to determine the operating conditions that improve biogas production. Most of the models currently reported do not consider the simultaneous effects of pH and temperature on the process kinetics ...

Memorias del Congreso Nacional de Control Automático, 2022
In this work, a search methods strategy based on optimization algorithms is proposed for the kinetic modelling of a dark fermentation process using tequila stillage substrate for hydrogen production. Kinetic model based on the ADM1 approach is fitted to the experimental data to evaluate the dynamic behaviour of the metabolites produced and consumed ...

Tequila vinasses: generation and full scale treatment processes
Reviews in Environmental Science and Bio/Technology, 2010The production of Tequila (55% Alc. Vol.) in Mexico for the year 2008 was 227 million liters, and consequently around 2,270 million liters of Tequila vinasses (TVs) were generated, which without proper treatment is equivalent to the pollution produced by 6.2 million people.

Anaerobic treatment of Tequila vinasses in a CSTR-type digester
Biodegradation, 2009Tequila 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 ...

In this study, showed a strategy to generate methane and remove organic matter removal from tequila vinasses through of anaerobic digestion assisted via bioelectrochemical power to-gas. Specific methanogenic activity (SMA) assays in batch mode were tested and a single-stage bioelectrochemical upflow anaerobic sludge blanket reactor (UASB) was evaluated

International Journal of Hydrogen Energy, 2020
Abstract The objective of this work was to comparatively evaluate the production of biohydrogen (bio-H2) from tequila vinasses at optimized mesophilic and thermophilic conditions and to elucidate the main metabolic routes involved. Optimal temperatures of 35 °C and 55 °C, and pH of 5.5 maximized the bio-H2 production rates, 25.5 ± 0.01 NmL h−1 and ...

Fractality in pH time series of continuous anaerobic bioreactors for tequila vinasses treatment
Chemical Engineering Science, 2014pH measurements taken from anaerobic digestion (AD) processes show fluctuations with an apparent random behavior that is usually associated to noise. However, it is well-known that the AD process is carried out on the basis of electron interchange from donors to acceptors.

International Journal of Hydrogen Energy, 2019
Abstract Hydrogen production from dark fermentation is a potential source of sustainable fuel when it is generated from waste. This study compared hydrogen production resulting from fermentation using raw and detoxified tequila vinasse. Vinasse was detoxified with granular activated charcoal, which was used to adsorb compounds that could inhibit the ...

Ozone: Science & Engineering, 2016
ABSTRACTThis article describes the study of the treatment of tequila industry vinasses based on the sequential application of coagulation-flocculation and heterogeneous catalytic ozonation. Coagulation-flocculation treatment used biopolymers to reduce the nondissolved organic matter and to reduce the degree of color units in effluent.

The goal of this research is to find a more effective treatment for tequila vinasses (TVs) with potential industrial application in order to comply with the Mexican environmental regulations. TVs are characterized by their high content of solids, high values of biochemical oxygen demand (BODs), chemical oxygen demand (COD), low pH and intense colour ...
