As we are unsure of the effects of pharmaceutical micropollutants in the water, researchers are seeking a way to eradicate these unnatural components. Wetsus researchers have found an effective manner to use photocatalytic ceramic membranes. By irradiating photons on the TiO2 membrane surface, surrounded by dissolved testing model compounds – diclofenac, iopamidol, methylene blue, and metoprolol – they were able to get rid of up to 97% of unwanted medicine scraps.
