Berson's medium pressure UV systems are being used in a trial in the Netherlands to treat hospital wastewater prior to discharge. In the trial, UV is applied in combination with hydrogen peroxide (H2O2) to generate OH- radicals in a so-called "Advanced Oxidation Process" (AOP). The very reactive OH- radicals attack the pharmaceutical residues in the wastewater, breaking them down into H2O, CO2 and harmless metabolites.
Like all hospitals, the wastewater from the Isala Hospital in Zwolle, the Netherlands, contains elevated levels of X-ray contrast compounds and various other pharmaceutical residues.
