In the physical wastewater treatment process, solid particles are removed through sedimentation, aided by flocculation and filtration. Flocculation is obtained by adding coagulants, which leads to aggregation of very small particles to form flocs. Again, sedimentation removes these flocs.

Management of Wastewater in Japan - GCUS
Japan has built a total of 460,000 km of sewer lines and 2,200 treatment plants for public wastewater service. The deterioration from aging may threat sustainability of wastewater service in the years ahead. The failed sewers cause around 4,000 cases of sinkholes annually. To improve this situation, asset management have been discussed and

1. Introduction. Wastewater basically includes the water supplied by communities after being utilized in various ways (showering, bathing, washing dishes and clothes, and using toilet) that deem or make it become incongruous for use before treatment (韦chobanoglous et al., 2003; Metcalf and Eddy, 2014).It has various levels of pollutants depending upon the type of wastewater (black water
