17 Sep FEco TiO2 filaments used to print porous membranes for water treatment in Photocalytic Membrane Reactors (PMRs).
Our filament FEco TiO2 has been used in a research work to additively manufacture scaffold to be used in Photocalytic Membrane Reactors (PMRs). The printing process has been optimized in terms of thermal rheology and the printed scaffolds show excellent activity in the photocatalytic degradation of organic compounds (Methyl Orange) dissolved in water. This work compares the use of 3D scaffolds with tape cast planar membranes of PLA with the same nanosized titania inside. The printing accuracy achieved with our filaments allows regular openings sizes of 650 µm in the linear grid configuration and a range between 450 and 850 µm in the gyraoidal ones. Gyraoidal geometries present higher degradation rates than linear providing very promising results of the filaments and the FFF technique as a solution for the fabrication of easily extractable self-supported membranes for water treatment for the use in PMRs.
