Propranolol is a beta blocker used to treat high blood pressure or an irregular heart rate. Using our Nyex treatment process we removed 99% of propranolol from municipal wastewater – from 0.0004 µg/L to below the limit of detection. In another project, we removed from 0.26 µg/L to 0.02 µg/L, showing the system’s capabilities both at trace and low levels of contamination.
