We evaluated four types of biomass carrier for treating disposer wastewater at high BOD loading rate, and designed the treatment plant to purify wastewater from condominium disposer system. The BOD removal efficiency was correlated with the biomass retaining capacities of the carrier, and, among the carriers studied, polyurethane cubes showed the highest BOD removal at the BOD loading of 2.0 kg⋅ (m<SUP>3</SUP>⋅d) <SUP>-1</SUP>. Our results indicated the relationship between influent BOD sludge loading and BOD removal sludge loading. Therefore, on the basis of this relationship, we designed the treatment plant for purifying wastewater from the disposer system in a condominium, supposing that 32 persons was dwelling, and evaluated the treatment efficiency. In 1-year follow-up, this pilot plant showed the high BOD removal at all seasons.
