“…Sonophotocatalysis (consisting of a combination of ultrasonic sound waves, ultraviolet radiation and a catalyst) has recently emerged as an alternative water treatment method [8][9][10] due to several advantages: lower doses of catalysts and reagents, no need for low turbidity, etc. However, the use of high-frequency ultrasound demands high amounts of energy, so that an economical study in needed to quantify its applicability in each reactor type.…”

The photo-Fenton degradation of carbamazepine (CBZ) assisted with ultrasound radiation (US/UV/HO/Fe) was tested in a lab thin film reactor allowing high TOC removals (89% in 35min). The synergism between the UV process and the sonolytic one was quantified as 55.2%. To test the applicability of this reactor for industrial purposes, the sono-photo-degradation of CBZ was also tested in a thin film pilot plant reactor and compared with a 28L UV-C conventional pilot plant and with a solar Collector Parabolic Compound (CPC). At a pilot plant scale, a US/UV/HO/Fe process reaching 60% of mineralization would cost 2.1 and 3.8€/m for the conventional and thin film plant respectively. The use of ultrasound (US) produces an extra generation of hydroxyl radicals, thus increasing the mineralization rate. In the solar process, electric consumption accounts for a maximum of 33% of total costs. Thus, for a TOC removal of 80%, the cost of this treatment is about 1.36€/m. However, the efficiency of the solar installation decreases in cloudy days and cannot be used during night, so that a limited flow rate can be treated.

“…Conventional advanced oxidation processes are often coupled with sonolysis. In the past few years, large numbers of papers have been published that report use of sono–hybrid techniques for oxidation and degradation of various pollutants. − Despite encouraging results that show significant enhancement in the degradation efficiency (as compared to either of the AOPs applied individually), the exact synergism of the sono–hybrid process is less extensively explored.…”

Hybrid advanced oxidation processes (HAPOs) for degradation of recalcitrant organic pollutants have been extensively studied in recent literature. In this paper, we have presented a mechanistic investigation of hybrid advanced oxidation processes with combinations of sonolysis and Fenton process coupled with UV. Degradation of a ubiquitous pollutant, bisphenol A, discharged in environment with solid plastic waste has been used as the model reaction. Essentially, an attempt is made to explore synergy between the individual mechanisms of these processes. With conjectures of possible synergies, we have devised the experimental protocols with combination of sonolysis and Fenton process coupled with UV. It is revealed that techniques of sonolysis + Fe2+ and sono–Fenton have positive synergy while technique of Fenton process + UV has no synergy. The technique of sono–Fenton + UV has been found to have negative synergy. The rationales for positive synergy have been identified as conservation and/or regeneration of •OH radicals and increased probability of radical-pollutant interaction, while the absence of synergy is a consequence of low utilization of UV irradiation due to lesser fractional energy at absorption wavelength (254 nm) of H2O2. A probable cause for negative synergy is conjectured as hindrance to effective utilization of H2O2 through sonolysis and Fenton process route by UV irradiation. The highest mineralization, monitored through total organic carbon (TOC) of the solution, was obtained with the sono–Fenton process.

Water makes up most of the Earth, although just 0.3% is usable for people and animals. The huge oceans, icecaps, and other non-potable water resources make up the remaining 99.7%. Water quality has declined in recent decades due to pollution from population growth, industry, unplanned urbanization, and poor water management. The textile industry has significant global importance, although it also stands as a major contributor to wastewater generation, leading to water depletion and ecotoxicity. This issue arises from the extensive utilization of harmful chemicals, notably dyes. The main aim of this review article is to combine and assess the impacts of textile wastewater that contains dyes and chemicals, and to examine their potential consequences on human health, aquatic health, and the environment. Moreover, the dedicated section presents an in-depth review of various environmentally sustainable approaches for the management and treatment of wastewater in the textile industry. These approaches encompass bio adsorbents, biological methods, membrane technology, ion exchange, advanced oxidation processes, as well as physicochemical and biochemical processes. Furthermore, this study also evaluates the contemporary progressions in this particular domain, taking into account the corresponding advantages and disadvantages. Finally, this article highlights the significance of recovering and reusing dyes, alkalis, and electrolytes in wastewater treatment. Additionally, it emphasizes the necessity of performing technoeconomic analyses and life cycle assessments (LCA) on wastewater treatment plants.
