The Maishima Sludge Center will enable centralized and efficient treatment of sewage sludge from the city’s 12 wastewater treatment plants. It will be equipped with an incinerator to melt sludge and produce slag, which can be reused as construction material. The plant will be an environmentally sound facility in harmony with the surrounding area.
Currently, part of the sludge generated is melted into slag and reused, but the majority is transported to three plants, incinerated, and landfilled. The existing incineration facilities are in need of renewal and the introduction of advanced treatment and continued improvements in the sewerage system promises an increase in the volume of sludge to be generated.
Sludge melting furnace (150t/day x 6 units)
Dewatering units (60m3/hour x 6 units)
Treatment capacity: 900t/day of sludge cake
