TiO2 Photocatalyst Nanoparticle Separation: Flocculation in Different Matrices and Use of Powdered Activated Carbon as a Precoat in Low-Cost Fabric Filtration
Figure 5
Total solids concentrations (corrected for TS concentrations of the matrices) in 1 g/L TiO2 suspensions containing different amounts of Merck PAC or Hydraffin WG PAC in different matrices ((a), (b): 0.1 g/L NaHCO3 solution; (c), (d): 0.5 g/L NaHCO3 solution; (e), (f): 1 g/L NaHCO3 solution) subsequent to vacuum filtration over spunbond polypropylene fabrics.
