“…In the case of TOC, more beneficial results were obtained in the experiment with non-controlled pH (Table 2). Similar results were achieved by Ghosh Ray and Ghangrekar (2019) in the process of aerobic biodegradation of the effluent from anaerobic degradation of distillery wastewater. They reported reductions in COD and BOD 5 values by 74 and 96%, respectively, at HRT = 24 h in the case of pollution load of 3.6 kg COD/(m 3 day), and by 43 and 84% in the case of pollution load of 9.0 kg COD/(m 3 day).…”

We analyzed the effect of hydraulic retention time (HRT) and pH control of beet molasses vinasse on the efficiency of its continuous aerobic biodegradation with a mixed culture of Bacillus bacteria. Two experimental series were conducted in a 2-L stirred-tank reactor, at an aeration rate of 1 vvm, stirrer speed of 900 rpm, and temperature of 36 °C. The first series was run without medium pH control, whereas the other with pH maintained at 8.0. In both series, HRTs were 26, 47, and 78 h, whereas vinasse pH was raised to 8.0. The extent of its treatment via aerobic biodegradation depended on betaine assimilation phenomenon. High removal of pollutants (over 84%) expressed by the SCODsum index (SCODsum = soluble COD determined with the dichromatic method + theoretical COD of betaine) was achieved at HRTs of 47 and 78 h, whereas medium pH control had no explicit effect on biodegradation efficiency.

“…The temperature, time, catalyst, and interactions significantly affected the COD removal ( Table 2 ). In rice vinasses, the COD removal could be 83% using a fermentative process [ 23 ], and in wine vinasse, the reduction could be 40 to 60% with an anaerobic reactor [ 24 ].…”

Thermal Treatment to Obtain 5-Hydroxymethyl Furfural (5-HMF), Furfural and Phenolic Compounds from Vinasse Waste from Agave

et al. 2023

Vinasses represent important final disposal problems due to their physical-chemical composition. This work analyzed the composition of tequila vinasses and increased 5-hydroxymethylfurfural, furfural, and phenolic compounds using thermal hydrolysis with hydrogen peroxide as a catalyst. A statistical Taguchi design was used, and a UPLC-MS (XEVO TQS Micro) analysis determined the presence and increase of the components. The treatment at 130 °C, 40 min, and 0.5% of catalyst presented the highest increase for 5-HMF (127 mg/L), furfural (3.07 mg/L), and phenol compounds as chlorogenic (0.36 mg/L), and vanillic acid (2.75 mg/L). Additionally, the highest removal of total sugars (57.3%), sucrose (99.3%), and COD (32.9%). For the treatment T130:30m:0P the syringic (0.74 mg/L) and coumaric (0.013 mg/L) acids obtained the highest increase, and the treatment T120:30m:1P increased 3-hydroxybenzoic (1.30 mg/L) and sinapic (0.06 mg/L) acid. The revaluation of vinasses through thermal treatments provides guidelines to reduce the impact generated on the environment.

“…Distillery wastewater could cause many environment issues such as eutrophication due to its high generation amount and high concentration of organics and nutrients [1] . The compounds contained in the distillery wastewater mainly come from the making process including pretreatment and hydrolysis of crops or fruits, fermentation, distillation and dehydration [9] .…”
