Toshiba provides the High-speed clarifier
(Sedimentation tank) with the flow rate
4 times faster than conventional ones.

Here is main text.
Generally, in the fields of industrial water treatment, the conventional Clarifier (Sedimentation tank) needs a large space due to low speed of TSS(total suspended solid) sedimentation which causes the low flow rate of treated water.
Toshiba has developed a High-speed clarifier (Sedimentation tank) of which flow rate is 4 times faster than conventional ones by finding the suitable flow dispersion using the latest fluid simulation.
Separate TSS from the waste water by sedimentation at the high water liner velocity of more than 4m/h.（4 times faster than conventional ones）
Lower the construction costs by reducing diameter and height of the tank.
Footprints are 4 times smaller than conventional ones due to higher flow rate.
Toshiba developed the original structure by using latest simulation technology, which leads to higher sedimentation efficiency and flow rate than conventional ones.
1 The structure to distribute flocs Raw water from the feedwell are distributed uniformly into the Clarifier (Sedimentation tank).
2 The structure to prevent most flocs from carrying over Flocs along the wall are prevented from carrying over.
3 The structure to re-feed flocs into the feedwell Some flocs which have been carried over are fed into the feedwell again.
Pre-treatment and high-speed sedimentation are provided
Chemicals are added to the raw water, and small particles are formed into flocs which can be separated by sedimentation.
pH control is applied when necessary.
Flocs are separated from pre-treatment water by sedimentation. This equipment can treat more than 4 times as much flow rate as conventional ones.
The sludge are pulled from the bottom of the tank and sent to the sludge treatment process.
