“…This approach could include the creation of custom cavitation devices, designed exclusively for the treatment of vinasse. Likewise, strategies such as placing cavitation devices in series [62,78], in parallel [79], or in the bypass line [80] should be considered. The integration of modeling and computational simulation in the study of hydrodynamic cavitation processes in vinasse treatment systems also becomes a common need.…”

This review examined the viability of hydrodynamic cavitation as a pretreatment method to improve biodegradability and reduce toxicity in alcoholic vinasse. The growing interest in environmental impacts and the demand for sustainable solutions in the alcohol production industry have driven the search for efficient methods to treat vinasse, a complex and polluting by-product. The basic principles of hydrodynamic cavitation and its application in contaminant removal are explored in detail. Through a critical review of existing research, the efficiency of removal of organic load and recalcitrant contaminants, the influence of geometric parameters, the operational parameters of the process, and the challenges of applying hydrodynamic cavitation as pretreatment of alcoholic vinasse are analyzed. Despite its limitations, its potential as a solution to address pollution problems in alcohol production stands out. Ultimately, this review aims not only to collect and analyze the available information but also to encourage future research in this direction. Therefore, this review article is presented as an essential resource that guides future researchers and practitioners towards more sustainable and effective solutions, significantly contributing to environmental improvements in the industry.

“…In the literature, there are different works where the process of dye degradation is addressed using methods such as adsorption, biodegradation, ultrasonification, photocatalysis, and Fenton degradation . However, these methods often require long treatment times, include the use of expensive compounds, and end up producing secondary contaminants that are more complex to degrade …”

The decolorization of the Basic violet I (BVI) dye when interacted with a corona discharge is studied in the present work, taking in account two systems, batch and flux. The current and voltage were measured during the whole process in which a corona plasma was generated, with an applied power of 51.9 and 167.72 W where the transport gas was air. A batch reactor and a flow reactor were used, where 500 and 5000 mL of samples were treated, respectively. Optical emission spectra (OES) were measured where the oxidizing species •OH were at wavelengths of 307.597 and 310.148 nm, associated with the A 2 ∑ + − X 2 Π transition. The absorption spectra for the batch system showed a discoloration of 85.7% in the first 10 min, while in the flow system, the absorption was 93.9% at the same time and 4.5% at the same time by conventional heating. Characteristics of the final sample included an acidic solution with an electrical conductivity of 449.20 ± 55.44 and 313.6 ± 39.58 μS/cm, a dissolved oxygen concentration of 7.74 ± 0.2 and 6.37 ± 0.23 mg/L, an absorbance of 0.04 ± 0.01 and 0.03 ± 0.01 au, with turbidity measuring 1.22 ± 1.59 and 10.34 ± 4.96 NTU, and an energy cost of 1.1 × 10 −1 and 6.3 × 10 −1 g/ kWh in the batch and continuous flow systems, respectively. The interaction of the corona plasma with water promoted the production of reactive species, resulting in the discoloration of the Basic Violet I dye.
