Table 7 Nature and extent of pollutants removal by sonication and hydrodynamic cavitation- assisted AOPs.
Technique(s) | Pollutant(s) | Matrix scale | Kinetic results | Ref. |
|---|---|---|---|---|
(i) Photocatalytic oxidation (ii) Sonication, (iii) Hybrid of the former and latter | Acid Orange 52 Dye | Lab scale synthetic solution | In sonication, the dye decomposed almost entirely in 300 min with TOC reduction by 13% in 480 min | |
Hydrodynamic cavitation | E. Coli | Lab scale synthetic Solution | Effective in killing the bacteria but depends on several factors | |
Hydrodynamic cavitation | E. Coli | Lab scale synthetic solution | 75% of bacteria cell stopped dividing in 3 min Bacteria do not die but enters into an active but non-cluturable phase | |
Hydrodynamic cavitation | Benzene, toluene, ethylbenzene, and xylenes (BTEX) | Lab scale synthetic solution | Toluene and ethylbezene degradation rate is 21% and 13% in 240 min, respectively | |
Sonication | Polyaromatic hydrocarbons (PAH) | Lab scale petrochemical industrial wastewater | Total PAH removal of 97% in 150 min | |
Sonication | Phenols, total aromatic amines, COD | Lab scale olive mill wastewater | Removal of COD, phenols, and total aromatic amines were achieved maximally to 68%, 78%, and 71%, respectively | |
Hydrodynamic cavitation | Carbamazepine | Lab scale synthetic solution | 27% conversion of the pollutant in 15 min | |
Hydrodynamic cavitation | Microcystis aeruginosa | Lab scale synthetic solution | Reduction of density and Chlorophyll in the cell in 10 min by 88% and 94%, respectively | |
Hydrodynamic cavitation | Ibuprofen | Lab scale synthetic solution | >60% Ibuprofen degradation in 60 min, initial pH = 3 |
