“…In the past several years, several simple AOPs, such as photocatalytic oxidation (PCO), ozonation (O 3 ), sonolysis (US) and electrolytic oxidation, have been investigated for organics removal from the RO concentrates [9][10][11][12][13][14][15][16][17]. However, in most cases, these AOPs could only mineralize small fractions of the organics.…”

Escherichia coli (E. coli) and Bacillus megaterium bacteria were frozen at 2158C using a freezer and a spray freezing method. The frozen Bacillus spores were also exposed to UV and free chlorine. An average of 4.7-log inactivation was obtained from the spray ice with 2-day storage time, while the freezer freezing only caused 0.84-log reduction with the same storage time. Significantly higher inactivation levels were observed for the E. coli cells with 2-day storage compared with those without storage. The spray freezing was found more effective in killing the E. coli cells, while more cells were sublethally injured by the freezer freezing. Freezing did not kill the Bacillus megaterium spores, but affected their response to UV and chlorine. Greater inactivation levels were observed at higher free chlorine doses or longer contact time, and the UV fluence-response curve showed initial rapid kill followed by tailing for the frozen spores.

“…Applying an oxidation process alone (e.g., ozonation (O3), photocatalytic oxidation (PCO), electrolytic oxidation, and sonolysis (US)) may not be efficient in the oxidation of the organic components present in ROC (Hege et al, 2004;Facey and Smith, 2001). Excessive oxidant dosage, high intensity of energy load, and extended reaction time appear to be insufficient to achieve satisfactory organic removal effectiveness .…”

ROC and biomass production was compared in a batch treatment system using both immobilised and suspended cultivation methods. The remediation performance of the microalgae system was also investigated with a semi-continuous treatment mode to learn the likely performance of the algal system in a continuous treatment manner. This work provided a basis to the further research in this treatment approach, with a view to facilitating its possible implementation.
