Resumen
Coupling UV photolysis, stable photoactive TiO2 layers and water filtration in a single photocatalytic membrane reactor can be beneficial to achieve high quality drinking water since the membrane retains microorganisms and chemical pollutants whereas the photocatalytic treatment decreases fouling components and treats the concentrated retentate.
In this work, a newly designed photocatalytic membrane reactor combining filtration with UV photolysis/ photocatalysis under a low pressure mercury lamp (wavelength emission at 254 nm) using ceramic modified membranes was used to treat filtered surface water inoculated with Aspergillus fumigatus. The photocatalytic membranes used in this study were produced using an environmental friendly modification process. Results showed high percentages of adsorption and retention of the spores for both the unmodified and modified membrane. The lower pore size of the modified membrane has the advantage of retaining the spores at the surface instead of trapping the spores inside as observed for the unmodified membrane. Direct photolysis ach- ieved retentate treatment percentages up to 99% after 60 min of treatment. The effect of the combined treatment showed that direct photolysis and photocatalysis were able to cause the deformation of spores and led to changes in membrane permeability and enzymatic activity.
