“…It is generally accepted that in order to start cavitation in a liquid medium, ultrasound wave intensity should be at least 1.0 W/cm 2 . It was found that with these parameters of the ultrasonic field, intensity of the ultrasound wave was higher than the theoretical threshold of cavitation and was 1.28 W/cm 2 [12]. After sonification process, COD content decreased substantially and was 3542 mg/dm 3 , whereas BOD was 1730 mg/dm 3 .…”

“…45 dm 3 /h). The measurement of the ozone content at the outlet from the reaction chamber was conducted using the Dreschel washing bottle with the absorption solution connected with the valve located at its top [11]. Sonication of the coke wastewater was performed using the Sonics vibro cell ultrasonic disintegrator which generated the ultrasonic wave with vibration frequency 40 kHz.…”

“…The value of the acoustic energy which was supplied to the wastewater sample for such parameters of ultrasound field was ca. 29885 J [12]. The exposure to the ultrasound field leads to cavitation, which is responsible for destabilization and oxidation of contaminants contained in wastewater using the hydroxyl radicals.…”

The aim of this research was to determine the effect the ozonation and sonification processes for post-treatment of coke wastewaters using activated carbons. The tests were carried out in three systems ie. I-AC (activated carbon), II-O3+AC (ozonation + activated carbon) and III-US+AC (ultrasound + activated carbon). In the experiment were used a three types of activated carbons: WG-12, ROW 08 Supra and Picabiol. The sorption process was carried out in static conditions at contact for 24h time of the wastewater with activated carbons. Coke wastewater was oxidized through ozonation at a constant ozone dose of 10 mg/dm 3 . Sonication of coke wastewater was conducted at vibration amplitude was 61.5 μm, with sonication time of 8 min. Results of removing of COD were estimated on the base of sorption capacity and COD removal efficiency. The second system was the most effective (O3+AC) for carbons WG-12 and ROW 08 Supra, whereas in the case of carbon Picabiol, the best efficiency was found for system I (AC). The lowest efficiency of removal of COD from coke wastewater was the systems III (US+AC) for all three activated carbons.

“…Since microfiltration membrane average pore sizes are larger than 100 nm, they are more suited to the removal of protozoa and bacteria rather than the smaller viruses [ 160 ]. However, this only considers separation by sieving mechanisms.…”
