Intensification of the degradation of Acid RED-18 using hydrodynamic cavitation

Emerging Contaminants, 2020
In this work degradation of Acid Red-18 (AR-18) was examined in the hydrodynamic cavitation reactor. Orifice plates with different holes geometry are used to determine the optimum plate to carry out the degradation based on cavitation number.

Occurrence of hydrodynamic cavitation

Water Science and Technology, 2011
In this paper, the conditions under which cavitation (or liquid film rupture) can or cannot occur in thin layers of moving liquid are derived for three typical cases. At the same time, expressions depending on geometrical and movement parameters, where cavitation might start, are given. The results are obtained using simple engineering terms, which can

Hydrodynamic cavitation-enhanced activation of sodium percarbonate for estrogen removal

, 2023
The present paper investigated the potential of hydrodynamic cavitation (HC) as an effective tool for activating sodium percarbonate (SPC). The method's efficiency was demonstrated by effectively removing estrogens, which are pollutants that have adverse
