Moving Bed Biofilm Reactors systems (MBBRs) have lately emerged as highly effective tools for treatment of wastewaters originating from various industrial sectors. System performance within the MBBRs is highly dependent on the carriers used, regarding efficiency in wastewater treatment (BOD/COD removal, heavy metal content reduction, nitrification and denitrification processes, various recalcitrant compounds removal etc.). Novel carrier structures have been obtained (patents pending), based on a mix of polyethylene with inorganic and organic compounds. Morphology analyses were carried out by Scanning Electron Microscopy, for assessment of internal surface structure, which will serve as an immobilization substrate for future bio-functionalization experiments. Chromatographic profile was assessed by Headspace Gas Chromatography, in order to identify Volatile Organic Compounds from the developed structures. The carried out analyses will serve as a starting point for future augmentation of the carriers with microbial strains.
