“…In addition, recently, Sarc et al [90] reported exploring certain new dimensions of cavitation formation, such as (super) cavitation via a venturi-type HC with a rotation generator that has effectively inactivated Legionella pneumophila, Escherichia coli, and Bacillus subtilis. Moreover, the disinfection capability of a green hybrid process utilizing HC along with natural clove oil was reported by Mane et al [91], which was also able to eliminate gram-negative E. coli and gram-positive S. aureus bacteria. The removal of waterborne viruses, such as enteric viruses (Rotavirus, Norovirus, Astrovirus, Sapovirus, Adenovirus) and Hepatitis A, is highly required due to their harmful effects.…”

The 20th century has witnessed a remarkable enhancement in the demand for varieties of consumer products, ranging from food, pharmaceutical, cosmetics, to other industries. To enhance the quality of the product and to reduce the production cost, industries are gradually inclined towards greener processing technologies. Cavitation-based technologies are gaining interest among processing technologies due to their cost effectiveness in operation, minimization of toxic solvent usage, and ability to obtain superior processed products compared to conventional methods. Also, following the recent advancements, cavitation technology with large-scale processing applicability is only denoted to the hydrodynamic cavitation (HC)-based method. This review includes a general overview of hydrodynamic cavitation-based processing technologies and a detailed discussion regarding the process effectiveness. HC has demonstrated its usefulness in food processing, extraction of valuable products, biofuel synthesis, emulsification, and waste remediation, including broad-spectrum contaminants such as pharmaceuticals, bacteria, dyes, and organic pollutants of concern. Following the requirement of a specific process, HC has been implemented either alone or in combination with other process-intensifying steps, for example, catalyst, surfactant, ultraviolet (UV), hydrogen peroxide (H2O2), and ozone (O3), for better performance. The reactor set-up of HC includes orifice, slit venturi, rotor-stator, and sonolator type constrictions that initiate and control the formation of bubbles. Moreover, the future directions have also been pointed out with careful consideration of specific drawbacks.

“…Moreover, the Venturi-shaped reactor could be realized in accordance with long established rules for circular-section ones [60], or in the form of generally more performing slit Venturi [43], as well as optimized by numerical simulations [62]. Other emerging setups could be used too, such as based on vortex diode [63]. The dosing pump is optional and could be useful for introducing any natural or technical additives.…”

Based on recent computational and experimental studies, hesperidin, a bioactive flavonoid abundant in citrus peel, stands out for its high binding affinity to the main cellular receptors of SARS-CoV-2, outperforming drugs already recommended for clinical trials. Thus, it is very promising for prophylaxis and treatment of COVID-19, along with other coexistent flavonoids such as naringin, which could help restraining the pro-inflammatory overreaction of the immune system. Controlled hydrodynamic cavitation processes showed the highest speed, effectiveness and efficiency in the integral and green aqueous extraction of flavonoids, essential oils and pectin from citrus peel waste. After freeze-drying, the extracted pectin showed high quality and excellent antioxidant and antibacterial activities, attributed to flavonoids and essential oils adsorbed and concentrated on its surface. This study reviews the recent evidence about hesperidin as a promising molecule, and proposes a feasible and affordable process based on hydrodynamic cavitation for the integral aqueous extraction of citrus peel waste resulting in hesperidin-rich products, either aqueous extracts or pectin tablets. The uptake of this process on a relevant scale is urged, in order to achieve large-scale production and distribution of hesperidin-rich products. Meanwhile, experimental and clinical studies could determine the effective doses either for therapeutic and preventive purposes.

“…After that, the applications of HC have begun to attract attention in a wide variety of areas, especially in the last few years (Figure 1). Nowadays, researchers have found that HC can be an effective tool for a number of chemical, biological, and other types of applications, e.g., microbial inactivation [bacteria (Mane et al, 2020), algae (Waghmare et al, 2019), virus (Kosel et al, 2017)], the removal of organic compounds (acids Choi et al, 2019, antibiotics (Tao et al, 2018, pesticides (Panda and Manickam, 2019), dyes Yi et al, 2018, pharmaceuticals (Rajoriya et al, 2019, fuel (Torabi Angaji and Ghiaee, 2015), phenols Chakinala et al, 2008, etc.,) decomposition of wasteactivated sludge (WAS) (Nabi et al, 2019), depolymerization (Prajapat and Gogate, 2019), denitrification (Song et al, 2019), desulfurization (Gagol et al, 2019), fibrillation (Kosel et al, 2019), intensification of biogas production (Zielinski et al, 2019), biofuel synthesis (Chipurici et al, 2019), liposome destruction (Pandur et al, 2020), catalyst slurry preparation (Nagalingam et al, 2019), viscosity reduction (Gregersen et al, 2019), residual stress relief, cleaning, and emulsification (Wu et al, 2019).…”

One of the most challenging issues for the large-scale application of nanomaterials, especially nanocarbons, is the lack of industrial synthetic methods. Sonochemistry, which creates an extreme condition of high pressure and temperature, has been thereby applied for synthesizing a wide variety of unusual nanostructured materials. Hydrodynamic cavitation (HC), characterized by high effectiveness, good scalability, and synergistic effect with other physical and chemical methods, has emerged as the promising sonochemistry technology for industrial-scale applications. Recently, it was reported that HC can not only significantly enhance the performance of biochar, but also preserve or improve the respective chemical composition. Moreover, the economic efficiency was found to be at least one order of magnitude higher than that of conventional methods. Due to the great potential of HC in the industrial-scale synthesis of nanomaterials, the present perspective focuses on the mechanism of sonochemistry, advances in HC applications, and development of hydrodynamic cavitation reactors, which is supposed to contribute to the fundamental understanding of this novel technology.
