TiO2 Photocatalyst Nanoparticle Separation: Flocculation in Different Matrices and Use of Powdered Activated Carbon as a Precoat in Low-Cost Fabric Filtration
Figure 7
Total solids concentrations (corrected for TS concentrations of the matrices) in 1 g/L TiO2 suspensions containing 2 g/L PAC ((a), (c)) and in 1 g/L TiO2 suspensions without any PAC ((b), (d)) at different NaCl ((a), (b)) and NaHCO3 concentrations ((c), (d)) subsequent to vacuum filtration over spunbond polypropylene fabrics.
