We will present the first LIFE PharmDegrade project results on the 6th Croatian Water Conference in Opatija with the following lecture:
Successful reduction of pharmaceuticals and herbicides from water: first laboratory-scale results of LIFE Pharmdegrade project”.
Numerous studies have been published about the presence of pharmaceuticals and phytopharmaceuticals in wastewater, ground and even in drinking waters. They present a significant burden for the environment and may cause health risks for the general population. Biological wastewater treatment plants are usually insufficiently equipped to treat pharmaceuticals. To introduce an efficient and financially viable technology for the removal of pharmaceuticals the demonstration project “LIFE PharmDegrade” has been supported. The technology is based on the advanced oxidation processes. The goal of the preliminary tests was to define degradability rate of 11 different pharmaceutical and phytopharmaceutical compounds and in different concentration ranges and presence of other organic material in drinking water. The selected compounds were subjected to LC-MS/MS analysis. Our results show that BDD exhibited high removal of pollutants, reaching up to 100 % degradation in 60 minutes of treatment. At higher concentration mixtures (100 µg/L per pharmaceutical), the removal capacity was lower. The present study shows that the advanced oxidation processes have a promising potential to be developed into an efficient wastewater treatment device for removal of potentially harmful pharmaceutical and phytopharmaceutical pollutants.
