Biologically treated industrial wastewater disinfection using the synergy of low-frequency ultrasound and H2O2/O3
Biological wastewater treatment is mostly used in many industries to treat industrial influents. Treated water is consisting of an extremely high concentration of pathogenic microorganisms. Present work demonstrate the treatment of biologically treated sugar industry wastewater (BTSWW) using a low-frequency ultrasound (US). BTWSS consists of Enterobacter, Salmonella, and Escherichia Coli with a total coliform concentration of 2500 ± 300 CFU/mL. Experiments were performed using the individual effect of US, H2O2, and O3 and the combined effect of US with H2O2, O3, and H2O2 + O3. The complete removal of total coliform was obtained for the synergy effect of US with H2O2 and O3. The performance of the process was analyzed based on pseudo-first-order kinetic rate constant and synergy coefficient. The pseudo-first-order kinetic rate constant was 21.6 and 22.3 × 10–2 min−1 with a synergy coefficient of 2 and 1.9 for a combined effect of US with H2O2 and O3, respectively. Another advantage of the synergy of US and O3 was lower requirement of the initial dose of H2O2 (2.1 mM/L). The operational cost of the process was found to be $ 1.5 × 10–2 /MLD.
