The effect of hetero-aggregated feeds on critical flux

Membrane fouling by flocculated particulate mixtures formed by silica (SiO2) and alumina (Al2O3) was studied. The properties of the particulate mixtures formed depended on the properties of the solutions. The effect of floc properties and temperature on the apparent critical flux was studied by flux stepping. Critical flux increased with operating temperature and decreased with pH and ionic strength of the mixture.
