Frequency Ultrasound

The saturate granular activated carbon(GAC) which adsorbed Ni2+ is regenerated using dual-frequency ultrasound. The individual frequency is 45KHz, 80KHz and 100KHz respectively. The experimental results show that the regeneration efficiency using dual-frequency ultrasound is better than that using single- frequency ultrasound under the same experimental condition. When the two ultrasound’s frequency is 45KHz, the regeneration efficiency is 81.03%, comparing single- frequency ultrasound it increase by 40% and it is the best in six group dual-frequency ultrasound. In conclusion, the dual-frequency ultrasound regeneration showed a possibility as an alternative to chemical and thermal regeneration of GAC.

In Harelbeke a Water Treatment Plant with a capacity of 15,000 m3/day, using Schelde river water has been in operation since April 1995. The treatment process comprises nitrification, dephosphatation by direct filtration, storage into a reservoir, direct filtration, granular activated carbon filtration and disinfection. The design of the three-layer direct filters was based on pilot experiments. The performance of the plant during the five years of operation is discussed. It was found that the removal of atrazin by activated carbon depends on the water temperature.
