Post-treatment of coke wastewater on activated carbons
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 + a...

| description | 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/dm3. 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. |
