Abstract: Floating filter media are provided to improve the efficiency in treatment of suspended solids, organic materials, and nutrient salts, which are contained in wastewater, by mixing activated carbon and sand when the floating filter media are foamed, so as to increase surface areas and densities of the floating filter media. Floating filter media fill a bio-filter system to filter off wastewater. Large-sized filter media(3) have relatively greater densities than small-sized filter media. The large-sized filter media are positioned below the small-sized filter media due to density difference even after backwashing in the bio-filter system so that waste inputted in an upflow type is efficiently filtered off. The large-sized filter media have particle sizes of 5-7 mm, and densities of 0.060-0.090 g/cm^3. The large-sized filter media are prepared by preparing resin beads, mixing 3-4 wt% of volatile foaming agent, 30-80 wt% of water, 0.1-1 wt% of dispersing agent into 16.9-65 wt% of resin beads, agitating the mixed matter in an internal pressure container, heating the stirred matter at a temperature of 147-156°C and a pressure of 1.3-3.5 kgf/cm^2, and foaming the heated matter while discharging the heated matter.
