AB - A system for treating waste water containing surfactants using a photo-oxidation catalyst combined with ultrasonic irradiation was investigated. The system consisted of two reaction chambers installed with ultrasonic transmitters of different frequencies to enhance the photo-catalytic reaction as well as to recover the photocatalyst particles used. An ultrasonic transmitter with a frequency of 200 kHz was used the reaction to enhance in the first chamber. An ultrasonic transmitter with a frequency of 28 kHz was installed for particles recovery in the second chamber. Glass beads (hereinafter GB) were used as the collectors as well as the accelerators of the agglomerated photocatalyst particles under ultrasonic irradiation. Waste water containing a surfactant, i.e., polyoxy-ethylene-alkyl-ether (C14H29O(CH2CH2)7H, hereinafter SS-70) with an initial concentration of 100 ppm and a volume of 1000 ml was used as a sample. It was confirmed that after three times of recycling tests there was no significant loss in catalyst activity.
