Fabrication of Porous Biochip Material Based on HDPE with Microbiological Compatibility and Orientation for Domestic Wastewater Treatment using MBBR Technology

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.
