“…Still, only a tiny fraction of this can be used for domestic purposes. Recycling and reusing water is a better option for accomplishing the water demand, so wastewater treatment has become indispensable to fulfil the water demand worldwide (Suresh et al 2021) for agricultural, industrial, and domestic usage (Kumari et al 2018;Suresh et al 2018;Gupta et al 2021).…”

This research presents the sonocatalytic degradation of naphthalene from an aqueous medium using a zinc oxide (ZnO) catalyst synthesised by the thermal decomposition method. The present paper also aims to apply the response surface methodology for the evaluation of the effect of different parameters on the degradation rate. The optimum parameters were found to be 50 min of reaction time, 2.2 g/l of the ZnO catalyst mass, 30 °C, 280 V, and 80 mg/l of initial concentration under a constant ultrasonic treatment at 20 kHz and 260 W of power intensity. The elemental composition of the catalyst was as follows: Zn 25.18%, O 37.03%, Mg 3.20%, K 0.83%, Ca 4.05%, N 5.07%, Na 4.13%, Cl 3.43%, and Fe 0.32%. Fourier Transform Infra-Red (FTIR) confirmed the Zn–O bond stretching at 510 cm−1. The degradation efficiency of naphthalene was almost double when the ZnO catalyst was used. The naphthalene degradation rate was a first-order reaction. Analysis of variance (ANOVA) results show that the quadratic model is suitable for the obtained data (P-value = 0.0001) and in an optimal process, performance conditions were set equal to 100%. Regression analysis with a high correlation coefficient (R2 = 0.989) and the model F-value of 6.94 indicated the adequacy of the model. The reusability study revealed that ZnO as a catalyst sustained the catalytic activity over five cycles.

“…Polycyclic aromatic hydrocarbons (PAHs) are a group of hardly degradable substances which are also widely spread in the environment as a consequence of natural and anthropogenic processes such as fires, volcano eruptions, petroleum spills, tobacco smoking, and incomplete combustion of fuels. Furthermore, they are commercial use in the plastic and chemical industry, agriculture, pharmaceuticals, and photographic products [20][21][22][23]. In the environment, over 100 PAHs were already identified, however, according to U.S. Environmental Protection Agency (USEPA), 16 of them have the greatest impact on human health and the environment [24,25].…”

“…For instance, Girardin et al [31] indicated that PYR concentration in the sediment of sedimentation pond could be the highest among PAHs. Due to the fact, that efficiency of the conventional treatment methods might be not sufficient in the removal of the above-mentioned substances, modern techniques should be developed [9,21]. An interesting alternative to the traditional treatment methods is the ultrasonication process which is considered as an effective technology in the removal of many harmful substances such as bacteria, algae, dyes, viruses, industrial chemicals, pharmaceuticals and personal care products (PPCPs), and hormones ( Nowadays, there is also the tendency to combine the ultrasonication process with other advanced oxidation processes (AOPs) due to economic reasons [43,44].…”

“…Recently, it was also found that ultrasonication can be effective when it is combined with membrane techniques because of the so-called fouling limitation [45][46][47]. According to literature data, ultrasonication could be effective also in BPA and PYR removal from the environment [4,8,9,21,[48][49][50][51][52][53]. However, there is a lack of knowledge about the removal of BPA and PYR from the retention basins water matrices by using ultrasound, thus, the study is the first research on determining ultrasound (US) technology efficiency for BPA and PYR removal from highway retention basin.…”

Due to the so-called road run-off, many various contaminants including Bisphenol A (BPA) and Pyrene (PYR) could enter the environment and retention basins. It was also suggested in the literature that their removal by using conventional treatment methods could be problematic, and modern techniques should be developed. In this study, the first attempt to remove BPA and PYR by using ultrasonication as a single process and with UV irradiation assistance was performed. The results showed that after 30 min of sonication, the degradation rate of BPA reached 92% while PYR was completely removed, however, after 1 min of the treatment degradation rate of BPA was significantly higher than PYR. In the study effect of pulsed ultrasound was also evaluated and it was found that its effectiveness in micropollutants removal could be higher than ultrasonication in continuous mode. Research revealed that the maximum removal rate of BPA and PYR was obtained during the ultrasonication process combined with UV irradiation-30 min of treatment resulted in 95% of BPA degradation. However, toxicity assessment showed that with an increase in the treatment time, an increase of toxic effects occurs. This phenomenon might be related to degradation of by-products formation which were identified in the study.

“…In general, aromatics are considered as substances that are hard to remove biologically, and thus, other techniques need to be developed [5]. One which can be used in water treatment is acoustic cavitation technology, which is defined as the formation of acoustic bubbles due to ultrasound, and their subsequent collapse in given conditions.…”

The articles reveal the removal effectiveness of 7 polycyclic aromatic hydrocarbons (PAHs), which were recognized in water from a highway drainage system by using the ultrasound treatment process. Results showed that after 45 min of sonication, the average removal of PAHs reached 59%. The reduction of analyzed substances was proportional to treated time and irradiation amplitude. Furthermore, as a consequence of ozone addition to the sonicated samples, the efficiency of the treatment was significantly higher.
