KDS Separator Patented Product (Japan)
The number of units sold : 1050 units (August, 2020)

Hybrid Model - combines two functions

- Solid-Liquid Separation
A solid-liquid separator is used for various purposes, such as industrial wastewater/livestock wastewater treatment, residue removal from industrial wastewater and sludge thickening. One of the problems that conventional machines have is that their filter screens get clogged easily. Cost and labour are required to remove the clogging.
We developed the cutting-edge mechanism with a unique self-cleaning function. The filter does not clogs without backwash water. KDS separator enables reduction in installation cost, life-cycle cost. Besides, the footprint is smaller.
- Sludge Dewatering
KDS separator can be used as a sludge dewatering device, as well. The original pressurization mechanism reduces water content and the amount of discharge. Besides, the discharged cake has been composted or utilized as cement raw material. This contributes to 3R(Reduce, Reuse, Recycle).

Swing Engineering Corporation


Our business partnership with Kendensha has started from when we adopted KDS Separator as a primary treatment device for our dewatering system. Since then, more than 100 KDS Separators have been installed with our dehydrators for sludge recycling in sewerage and plant wastewater fields. They are indispensable for our sludge treatment system now. Besides, Kendensha not only supplies excellent products but also has technical capabilities and agility to meet our demands. We, therefore, trust them as a partner for research and development as well.



The problems of widely used dewatering devices or solid-liquid separators are that significant decline of the processing capacity from filter clogging and costs and labour for inside cleaning. Since KDS separator solves those problems, we can suggest our clients better solutions which are labour saving, simple and easy to maintenance, on reduced running cost. Even the initial cost is lower than other equipment which has equivalent treating ability. So, KDS separator is our main product for both new and existing clients who are replacing their devices.
