Abstract: In this article, presents research on the application of MBBR technology using porous HDPE/PEO carriers for the treatment of hospital wastewater. The results showed the effectiveness of treating analytical parameters (pH, BOD, TSS, NH4+, NO3-). Porous polyethylene (PE) carriers were modified with polyethylene oxide (PEO) and polyethylene glycol methyl ether acrylate (PEgMA) to enhance bacterial adhesion and growth. The obtained carriers had a density of 0.61 g/cm³ and a porosity of 40.48% with pore diameters in the range of 50-500 µm. The efficiency of the carriers in treating domestic wastewater was evaluated at Hung Yen Eye Hospital. After 8 weeks of operation, the significant removal of ammonium reached 99.8% and the Nitrate parameters also decreased significantly. These findings highlight the potential of PE-based materials in promoting MBBR technology for effective treatment of domestic wastewater, providing a sustainable and scalable solution.
