AB  - In this paper, the decomposition of Rhodamine B (RhB) by hydrodynamic cavitation 
      (HC), acoustic cavitation (AC) and the combination of these individual methods 
      (HAC) have been investigated. The degradation of 20 L RhB aqueous solution was 
      carried out in a self-designed HAC reactor, where hydrodynamic cavitation and 
      acoustic cavitation could take place in the same space simultaneously. The 
      effects of initial concentration, inlet pressure, solution temperature and 
      ultrasonic power were studied and discussed. Obvious synergies were found in the 
      HAC process. The combined method achieved the best conversion, and the 
      synergistic effect in HAC was even up to 119% with the ultrasonic power of 220 W 
      in a treatment time of 30 min. The time-independent synergistic factor based on 
      rate constant was introduced and the maximum value reached 40% in the HAC system. 
      Besides, the hybrid HAC method showed great superiority in energy efficiency at 
      lower ultrasonic power (88-176 W). Therefore, HAC technology can be visualized as 
      a promising method for wastewater treatment with good scale-up possibilities.
