TiO<sub>2</sub> Photocatalyst Nanoparticle Separation: Flocculation in Different Matrices and Use of Powdered Activated Carbon as a Precoat in Low-Cost Fabric Filtration

<table>Total solids concentrations (corrected for TS concentrations of the matrices) in 1 g/L TiO<sub>2</sub> suspensions containing different amounts of Merck PAC or Hydraffin WG PAC in a matrix of biologically pretreated greywater ((a), (b)) and secondary municipal effluent ((c), (d)) subsequent to vacuum filtration over spunbond polypropylene fabrics.</table>
