In present study, a novel biocarrier was fabricated from wood and high density polyethylene (HDPE)using a single screw extruder. The effect of wood:plastic mass ratio on physico-chemical properties ofthe obtained wood plastic composite (WPC) was evaluated. While the tensile and flexural strengthswere decreased, the sample density was increased with higher wood contents. The wood:plastic massratio of 1:1 was considered as the best for the production of WPC biocarriers. The role of this materialin moving bed biofilm system was tested in a batch mode reactor having volume of 2 L with 20%filling by the biocarrier. The treatment efficiencies of organic matter, ammonia and phosphate wereenhanced nearly two times. The results are attributed to heterogenous and porous surface of WPC,which enhances bacteria adhesion and pollutant removal. It demonstrates that WPC can be a potentialbiocarrier for use in moving bed biofilm reactors (MBBRs).
