The dynamic filtration method produces a high permeation flux with a slight head loss and is considered to have the separation capability more than several times higher than the conventional sedimentation basin method. In this study, continuous demonstration experiments were carried out with the dynamic filtration applied to the wastewater treatment. The treatment performance in the nitrification-denitrification treatment of housing estate sewage and the filtration performance in the activated sludge treatment of food wastewater were verified. In the nitrification-denitrification treatment, high filtration performance and stable nitrogen removal performance could be confirmed. In the food wastewater treatment using a maximum 100 m^3/d pilot plant, stable treatment performance such that, for the MLSS 6,OOOmg/L, the flux was above 2m^3/m^2d on average and the permeate SS about 10 m/L on average, could be confirmed.
