Excess sludge
1. Small footprint The high concentration MLSS operation allows the reaction tank to be downsized and the sludge thickening tank to be eliminated. 2. Good quality of treated water Filtration with a fine bore (nominal bore diameter 0.4 µm) produces good-quality treated water without E. coli, protozoa, etc. and recycled water. 3. Easy maintenance Separating solid and liquid through a membrane does not basically require attention to sedimentation, resulting in easy maintenance.
