Sludge Dewatering and Drying System
By combining our dewatering press with our dryer, we can offer a complete dewatering and drying unit.
Dewatered cake from the dewatering press will be fed directly to the dryer. It reduces sludge volume by drying waste activated sludge or chemically sedimented sludge up to 60 to 90% dry solids content. We offer electric rotary kiln type, SP series ( offered only in Japan ), and steam drum type, K series.
SP SeriesElectric heat source ( offered only in Japan )
We managed to design this dryer to be compact with our own double layered drum structure, creating sufficient surface area while maintaining high heat exchange efficiency with direct contact of sludge to the heat source.
Dried sludge is discharged in the form of flakes by combining the dryer with VOLUTETM Dewatering Press, minimizing the scatters of dried sludge making it easier to handle. In addition, it offers the advantage of dried sludge being less likely to decay than dewatered cake, consequently providing less odor during the temporary storage of the sludge.

- 1Discharge of dewatered cake
-
The dewatered cake with solid content of about 17%, discharged from the sludge dewatering press, is in turn fed into the dryer.
- 2The inside of the dryer
-
The dewatered cake fed to the dryer is gradually dried inside the drying drum.
- 3Dried cake
-
Dried cake with solid content of 60 to 90% is discharged.
Water content and weight of sludge
| State of Sludge | Water Content | Weight of Sludge Cake |
|---|---|---|
| Raw sludge | 99% | 10000kg |
| Thickened sludge | 96% | 2500kg |
| Dewatered cake | 83% | 588kg |
| Dried sludge | 40% | 167kg |
| 30% | 143kg | |
| 20% | 125kg | |
| 10% | 111kg |

K Series Steam heat source
Sludge dryer, K series is capable of decreasing a great amount of sludge-discharging with Steam-Heating Drum. Using after the sludge process of VOLUTETM dewatering press, it can make sludge cake (Assuming activated-sludge or chemically precipitated sludge) further drier one which has 10% ~ 40% moisture content.
* K Series is a product of KANKYO SETSUBI Co., Ltd.
